Forgot your password? By JohnyNovember 26, in Electric Guitars. I want to build myself a cab in the near feature and I thought it might be cool to have a cab with 2 different sized speakers.
I think it's a great idea. I mean, PA speakers often have a 15 and a horn in the same cab. Some have a 15, a 6 and a horn. Bass cabs are the same way. Also, there's at least one model of Gibson Goldtone amps that has a 10" and a 12" in the same cab. Just match the impedance to your amp. You can get just about any size speaker in just about any impedance you want.
Other than a low frequency driver and a high frequency driver with a proper crossover, the more effecient driver is typically going to over power the less effecient driver.
We're you thinking of having a 12" full range driver and a 6" or 8" full range driver? Or more like a 12" driver and a tweeter with a crossover between them? Well I was thinking something like a 12" and a 8". I have honestly no idea about the full range thing, nor how to do a proper crossover. Well it certainly seems interesting.
I want to say it was Fender but I think I would be wrong but someone made a cab with 2 12s and 2 10s. I have been toying with the idea of re-doing a cab with 4 different speakers as in Manufacturers. Try a Celestion, Eminence, Carvin and something else perhaps. Trying to match the wattages close so there would be no one speaker working any harder or less than the other.Body found today
Obviously the impedance would be matched. I know it'll not be perfect, but actually doing it is the best way I know in order to learn stuff. With a guitar cab with 2 10s and 2 12s, you're not really going to be running a 2 or 3 way system, so no crossover is needed.
There will be some difference in the tonal character of the different speakers regardless. It's basically the same as mixing 2 types of 12" speakers in the same cab. Unless you're running a modeller and a transparent sounding power amp, you don't want a full range cabinet for your guitar anyway. While I agree that there is a lot of engineering that goes into cab dimensions and porting, for your basic guitar cabinet, there are some suggested guidelines, but really there's no set formula for what's going to sound good.
I've read many times that Marshall cabs were just basically built, not engineered to sound like they do, yet people are still raving about the Marshall sound 40 years later. I've put two different Celestions in the same cab Don't worry about the wattages.
Even you put a 30, 50, 75, and watt speaker in it, the same amount of juice is going to be going to each speaker.When designing a cabinet for guitar speakers, the cabinet's size,shape and construction are of far higher significance than the internal volume.
Guitar speaker cabinet design using Thiele Small parameters ignores these most fundamental aspects. Important factors include the material you make the cabinet from, the panel sizes and shapes, how they are joined, how the cabinet is finished, the mounting of the speaker, etc. These, not Thiele Small parameters are the critical factors in the design and ultimately the sound of a guitar speaker cabinet. Lead guitar speakers are a unique area of loudspeaker design.
A loudspeaker is usually a transducer, designed to faithfully reproduce the acoustics of the signal presented to it. An electric guitar speaker, however, is a creative part of the music, contributing its own character and tonality.
How Do You Match Amp Heads with Speaker Cabinets?
As guitar speakers are different, so their cabinets are different to hi-fi or PA cabinets. Designing the Guitar Cab. Guitar cabinets consist of two elements; a driver and a box. The box design is acoustically less critical than that for hi-fi or PA systems, but proper construction is essential. Remember that guitar speakers are quite heavy and amplifiers that sit on top of.
Maple, mahogany and walnut are often used for high quality cabinets. The important characteristics of the cabinet material are strength, sound and ease of use. When considering price, you should also consider cabinet finish. Open back or sealed boxes should be used. The box size is not critical.
Mount the speaker securely using bolts into T-nuts, not self tapping screws. Ensure the speaker is protected from the front, as the cone is easily damaged. We do not advise mixing different impedances of driver within the same cabinet.We do not advise mixing different impedances of driver within the same cabinet.
This can lead to uneven power sharing between speakers, causing one speaker to be overdriven and damaged, while the other is underdriven. Thiele Small parameters are useful for controlling the low frequency response of sealed or ported cabinet systems by changing the cabinet internal volume, and port dimensions.
However they are of severely limited use when designing a guitar speaker cabinet. Electric guitar speakers do not reproduce 'low' frequencies the low E string of a lead guitar has a fundamental of 82Hz and so the frequencies at which Thiele Small parameters have significance are mostly below the operating range.
Also, the parameters are measured at very small signal levels. Guitar speakers become non linear at very low levels compared to other types of speaker, greatly reducing the significance of Thiele Small parameters in actual speaker use.
Using the Thiele Small parameters of a typical guitar speaker, you will find that halving or doubling the cabinet size makes minimal difference to the response. They have no relevance to open back cabinets. Guitar speakers are not recommended for use in ported cabinets as the increase in cone excursion below the tuning frequency can cause the thin paper edge of the cone to tear.
The cabinet size, shape and construction are of far higher significance than the internal volume. Cabinet design using Thiele Small parameters ignores these most fundamental aspects. Important factors include the material you make the cabinet from, the panel sizes and shapes, how they are joined, how the cabinet is finished, the mounting of the speaker, etc.
These, not Thiele Small parameters are the critical factors in the design and ultimately the sound of a guitar speaker cabinet.Any top amp tech, thoughtful manufacturer, or clued-in player will tell you that your speakers are responsible for an enormous chunk of your tone. Despite this fact, the speaker is often the last thing a player considers in any quest to overhaul an unsatisfactory sound.
Indeed, early guitar amps rarely put out more than the higher figure, until the arrival of the watt Fender Twin of the late s, and a few others. These speakers were fine when used singly in small venues or recording studios, or in multi-driver cabs at dance-hall volumes.
As guitarists found themselves in bigger and bigger venues that required higher clean-volume levels, amp makers sought out more robust speaker designs. Whatever adjectives we apply to them, these performance properties combine to yield sweet, tactile clean sounds when driven a little, and gorgeous, rich, chewy overdrive when driven a lot.
Depending on availability, many of the same amp manufacturers also used speakers from Utah, Oxford, CTS, and others. These models usually shared some vintage Jensen properties, but are generally not as revered by players.
These speakers capture at least some of the tonal characteristics of the originals, although materials are not percent matches between the new and old units.
Major American manufacturer Eminence, which evolved out of the CTS company, also makes a number of vintage-American-voiced drivers, including its popular, long-running Legend speakers, and many speakers in the newer Patriot range.
The smaller Indiana-based manufacturer, Weber Speakers, likewise offers a range of highly regarded vintage-style units—many of which are based on Chicago-era Jensens. Across the pond, Elac, Goodmans, and Celestion were manufacturing speakers in the s that had broadly similar characteristics to their American cousins.
Using pulp-paper cones and alnico ring magnets to achieve power handling conservatively rated in the to watt ballpark, these appeared most famously as the Goodmans Audiom 60, and, more famously, the Vox Blue—a Celestion G12 relabeled by the amp manufacturer. The Blue has always been a highly efficient speaker, too—which means that it translates a relatively high proportion of the wattage pumped into it into volume.
The G12 has a sensitivity rating of dB measured by driving the speaker with one watt, and then evaluating the volume level from a distance of one metercompared to figures of 90dB to 97dB for similarly styled vintage Jensens and other speakers.
Such sensitivity means, for example, that a pair of G12s in a 2x12 Vox AC30 can produce a lot of noise from that plus-watts tube amp—even making it sound as loud as a watt or watt amp with less efficient speakers. Eminence covers both sides of the Atlantic by also offering a wide range of Brit-voiced drivers in its Red Coat line, and California maker Tone Tubby pays homage to the original alnico G12 with its hemp-coned speakers.
Likewise, Weber Speakers offers many units based on classic Celestion models, while Texas-based Kendrick has its own line of Blackframe, Brownframe, and Greenframe speakers.Restart java linux
Kendrick also distributes Fane speakers in the U. As already mentioned, the quest for more volume also sent amp manufacturers seeking speakers that could handle the power. The first such driver widely used by a major amp manufacturer came into play a lot earlier than our previous discussion might imply.
They succeeded in making Showmans hellaciously loud amps, and when added as an option to Twin Reverb combos a few years later, they also helped to make these amps both unfathomably loud and excruciatingly heavy. JBLs classically present firm lows, a round midrange with an edge of bark and a slightly nasal honk, and ringing, occasionally piercing highs.
There are speakers suited to loud playing—when you really want to cut through. Two other makers of advanced, modern-styled American speakers, Electro-Voice and Altec, started popping up in guitar amps in the s. Rated at watts, and still available today, it is famed for its ability to stand up to incredible punishment, and keep pumping out pristine clean tones and rich, detailed overdrive.
These watt drivers are known for powerful, full-throated clean tones, while translating cranked-amp overdrive tones with a minimum of speaker distortion. Many big names in vintage speakers survived to produce designs that fit more easily into the modern category. Celestion, for example, also offers the much-loved G12T, G12H, Classic Lead 80, and others—all powerful rock drivers with big voices and serious power-handling capabilities.
Meanwhile, many blur the lines between vintage and modern. Eminence carries robust speakers in its Legend, Patriot, and Red Coat ranges that have impressive power-handling specs, but achieve tones that fall more into the vintage-voicing camp. Similarly, the recently introduced Celestion Alnico Gold seeks to capture the tone of the watt Alnico Blue in a sturdier watt package. When we talk of speaker distortion, we mean a form of distortion—distinct from amplifier distortion—that is generated when a driver is pushed near its operating limits.
The voice coil and paper cone begin to fail to translate the electrical signal cleanly, and, as a result, produce a somewhat or, sometimes, severely distorted performance. The concept of such distortion is sometimes confusing, because it often occurs on top of any distortion the amplifier itself is producing. The distortion produced by a high-gain preamp stage—or a floored output stage—can occasionally be heard on its own when an amp is played through high-powered speakers that refuse to distort or distort very littleeven under high-output conditions.
Alnico is an alloy of aluminum, nickel, and cobalt blended with a quantity of iron. While this description of alnico implies a certain superiority, be aware that several classic speakers—even many vintage models, and those that remain the driver of choice for countless major players and tonehounds—were and continue to be made with ceramic magnets.Every now and then I am asked a question that directs my thoughts towards cabinet dimensions.
When I get to thinking, I often get to blogging. First rule: there are no rules. There are a plethora of "ideal size" cabinet calculators available. This is particularly true where open-back cabinets are concerned. I just took a quick inventory, and I have 12 1x12 combos, and no two of them have the same dimensions. Here is a quick run-down of a few notable models, all of which sound quite good in their own way. All dimensions in inches, rough, simply a quick tape-measure reading.
It is notable that all of these, save for the Burriss cabs, are open-back to varying degrees. The Burriss cab can be either open or closed back. In my view the lesson here is that, when it comes to an open-back cabinet, there is a great luxury of acceptable variance. And, of course the circuit itself! As Fender went on to higher power amps that used bigger speakers, Leo really just made the cabinets as big as was necessary to contain the chassis and speaker while allowing for easy access.
Leo, the old repair man, was always making stuff that was easy to service.Cool japanese names for games
So, my take on an open back cabinet is pretty much this: Make it something that will comfortably accommodate your speaker s and other size needs and make it about inches deep. Let the baffle resonate, and use a light resonant wood for the cab itself. Marshall may not have invented the closed-back guitar cabinet, but he sure perfected it.Barua mp3
A closed back cabinet has a lot more ability to influence the sound of a Driver than an open back, and I think that here the dimensions become quite important. Here, I will be very brief.
This wheel has already been invented by Mr. Jim Marshall; we need not re-invent it. The relatively new Marshall 1x12 18x20x My personal fav here is the slightly larger Avatar G at 24x For me, the difference between the really good sounding closed-back cabs and the ones that leave me wanting more usually comes down to this: the bigger box wins. Put head to head, a will blow away an MG 4x12 loaded with the same drivers. So, back to that "optimum size" calculator. Guitar speaker cabinets are like guitar speakers themselves; what looks good on paper rarely sounds good in real life.
Unlike, say, control room monitors, where you WANT a nice flat and wide response, guitar cabinets, generally speaking, should substantially color the sound. On paper, transistors whoop butt on tubes, but we all know which usually sounds better in real life.Mp3 andra respati
So, my suggestion on "ideal" size for a closed back cabinet is this: flatter Jim Marshall by copying his best cabinet designs. But, this is rare in guitar cabinets, and in real life these cabinets rarely fare as well in real live as on paper.
Good stuff in the land of bass bins and bass guitar cabs, not usually so good in guitar cabinets think WOOFY. Feel free to disagree, post it here if you wish. I believe there are designs for a 1 X 12" cab at the AX, I haven't heard it, but they come out with some good stuff.
Guitarplayer magazine liked the Port City Wave cab. Have you heard either cab and did you like them? My Somewhat Unconventional take on Ideal Speaker Cabinet Size Every now and then I am asked a question that directs my thoughts towards cabinet dimensions.
Is there anything I need to look out for when trying to match an amplifier head to a speaker cabinet? A: Matching an amp head with the right speaker cabinet can be a daunting task. However, if you know some basic things about amp head impedance, power, cabinets, and what to look for, it can make the task easier so you can choose an amp and speaker combination that will achieve the desired results. This way, your amp heads will run at optimal efficiency, produce the sound and output you are looking for, and protect your amp heads from damage so they can operate for many years to come.
An impedance mismatch between the amp and the speaker cabinets can cause serious damage to your speakers. To avoid impedance mismatch when selecting speaker cabinets you will need to know what the impedance of your amp heads is.
In order to properly pair a speaker cabinet with your amp head, be sure to check how many watts of power your amp will put out in different impedance modes, and that it is capable of running at the impedance the cab is wired for. Most modern amps have built-in features that allow them to determine what impedance to run at when you connect them to the speaker cab. The amount of power that an amp puts out for different impedances varies, so be sure you have enough power output for the volume and sound you desire to achieve.
Another important thing to check is that the cab can handle the load from your amp.
Can you mix speaker wattage in the same cabinet?
If the cab cannot handle the load from your amp, you will end up overdriving your speakers which will damage them. Another good feature of most modern amps is that they are equipped with a clip light indicator that lets you know if you are overdriving the speaker or not. This allows you to back off the volume and control power output to avoid causing unwanted damage. Also note that if you are going to run multi-speaker setups, this will change the impedance your amp runs up against.
Of course, there are the rarer high-end amps that have two power amp sections. The potentiality of these kinds of arrangements may come into play if you are playing to larger venues.
The most important thing to remember is that when you are matching your amp heads to speaker cabinets, be sure to check that the impedance and power output capabilities are compatible, that you will not be overdriving your speakers, and that you have enough power output for the volume you desire to achieve.

What are the differences between them?Which size Guitar Speakers do you prefer?
In this article, I will compare the two most common types of bass guitar enclosures and try to highlight the benefits and shortcomings of each. It took me a while to decide what details to cover, and I soon realized it might require a book to cover the concepts of cabinet design.
It would take a couple of articles this size just to introduce the terminology. For the DIY guys and players interested in obtaining more knowledge, there is a wealth of information available online to learn more about cabinet design. Whether you find information about car audio, home hi-fi, pro audio or bass guitar, the principles are basically the same. This article will be used for the details I feel will help bass players the most. A speaker produces minimal output in free-air outside of a cabinet.
These sound waves must be separated to achieve usable output. The baffle also absorbs vibration created by the speaker. A baffle that does not resonate with the speaker must be made from a solid and thick material. Any speaker will produce sound in any cabinet, but optimizing the relationship between the speaker and the enclosure is the key to good bass.
Thiele and Richard H. Small, devoted considerable effort to show how specific speaker parameters define the relationship between a speaker and a particular enclosure. They are a means of comparing speaker performance and finding optimal cabinet conditions.Svg image position
But, for now know that trade-offs are involved in every aspect. If you want deeper bass, punchier bass, tighter bass, more snap, pop, or whatever the desirable adjective, something else will be sacrificed to obtain it. Every amp and cabinet manufacturer has methods to achieve their signature tone. Speaker performance and cabinet design are equally crucial parts.
Designers must prioritize what performance or sonic characteristics they desire from a product and determine what aspects of the speaker and cabinet will make it a reality. Output level or SPLpower handling, frequency range, and size and weight are all considerations. When one is improved, other factors may suffer. The most difficult part is finding a middle ground.
The back of the speaker is completely sealed off from the front. The air inside the enclosure acts as a spring, which helps control the movement of the cone. When the speaker moves out, the pressure inside is decreased. When the speaker moves in, the pressure inside is increased. A sealed cabinet is considered a punchier, more accurate sound. Sealed cabinets are much easier to design and build than ported enclosures and are typically smaller in size.
