With the speaker cone traveling freely when triggered, the tone produced tends to have a loose, "airy" quality as compared to closed back cabs. Since the cab is not completely sealed, air is able to travel in and out freely, and as a result, the speaker cone can also travel backward and forward with little resistance from any type of air pressure/vacuum. Often a large section of the back baffle is open, exposing the back of the speaker. "Open back" - With this type of design, the back of the cabinet is not completely sealed. One major feature that is dicussed quite a bit when dealing with cabs is "open back" versus "closed back" Here is a general overview of the differences: With that being said, there are a few manufacturers that have tweaked the design in one way or another and the cabs that they produce bring a bit more to the table in the way of performance and flexibility than the basic design. This has been the same basic recipe for a long time and it works very well, so it is hard to say that one cab's construction can be better than the next. Most cabs on a very basic level consist of a wooden box with a speaker mounted on a flat baffle. In our experience, from a composition standpoint, the vast majority of guitar cabs are pretty similar and the design remains pretty consistent from one to the next. This is an important consideration when you are trying to decide which cab is best for your needs. Driving the speakers is a bit easier when the power from the amp as a whole is not divided between as many speakers. Just like any good tube amp, speakers have a range in which they sound their best, and sometimes you have to push them a bit to get the most out of them. Some of the tone of an amp comes from the way that a speaker is driven. With the power from the amp split among 4 speakers rather than say 2, each speaker is going to be given less power and in turn will not be driven as hard. This can be a good thing or a bad thing depending on what exactly you're trying to achieve. One thing to consider when you opt for a larger cab (more speakers) over a smaller cab (less speakers) is that you now have split the power into smaller "shares" as it relates to how much power each speaker is getting. It is better to think about the cab more as a delivery device, which is still very important in the grand scheme of things, but only in conjunction with the amp that is driving it. The design of the amp itself is really going to have the largest impact on how loud an amp is. Power - A guitar cabinet is not actually where the power comes from, but rather a means to convert that power into sound. Speaker technology has come a long way in the last 100 years with huge advancements in both materials and design, loudspeakers can now be built with extreme efficiency compared to previous designs.

Speaker efficiency- Not all speakers are created equally when it comes to how efficiently they convert the electrical current into kinetic energy (cone movement) and produce sound.

Many other factors are going to have just as large of an impact as the number of speakers. What you do gain with more speakers is more speaker cone surface area, and in theory, the ability to move more air. An important point to consider is that more speakers does not always mean louder.

A common misconception that we run into quite a bit is that larger cabs are louder than smaller cabs, when in reality that may not necessarily always be the case. With that being said, larger may not always be better when it comes to cabs, depending on your needs. There's always the natural tendency with almost anything to assume that there is an inherent benefit to "going a little bigger." Here in the states, we would argue that it is practically in our blood :). FINANCING Blowouts Gift Certificates Testimonials Reviews & Articles
