what would I need to do to use this just for a guitar amp, I don't think I really need the tweeters, if not do I just shorten up the box or what?

Thanks for your web site Dave

Please take a course in audio engineering. This cab is a joke, a virtual recipe for comb filtering.

Response to BassBoy44:

While you are correct in your statement that side by side drivers (hooked to the same crossover point) should be avoided if possible, I think you're overlooking the application here. The delay you're referring to will hardly be noticeable in the typical club or bar. I think everyone would agree that a properly custom designed and installed line array and monitor speakers with the proper crossover, amplification, and filtering would be the best solution for any venue. However here we are dealing with a "portable" system that has to be a compromise in many cases. SPL, bass response, cost, and portability being much more of a concern than time-coherency

Your knowledge and comments hint that you are an engineering student... one of the pit-falls many engineering students fall into, is that they are given "Ideal" examples in class. These frequently have little to do with real world application.

Comb filtering in the way you mean, is mainly of concern when the delay varies over time or due to frequency. Here the delay is fixed due to the path from ear to driver. The frequencies are also an issue. Consider the wavelength of the frequencies involved with the woofers, and think of the almost negligible phase difference the or 5” difference from each woofer to your ear. Not only that, but the reflected sound from the venue walls, usually far from "Ideal" in the places such a speaker would be used, will add far more of a time-coherency issue than driver placement.

You've always got to keep the end-user in mind. Not many PA solutions require audiophile quality speakers... I've found that the requirements for good PA cabinets are: (in no particular order) 1. Durability (and the ability to be used for multiple applications), 2. SPL (Loudness) 3. Bass Response, and. Cost.

P.S. in the case of the x 10" if the woofers are arrayed properly, (and these seem to be close enough) at any reasonable distance from the baffle, the sound "combines" into a single (though somewhat more directional) source as if from a single driver with slightly less thanx the cone area.

I just have a question. I have a pair of old Steven Trusonic speakers that I am hooking up to a Sony amp. The problem is, the Sone only has 8 ohm speaker taps. Will the sound quality be the same hooking up these speakes to 8 ohms? Thanks.

Can this 4 x 10" be converted to double 10" split in the middle and have a vent on the bottom for a 60 Hz - 18 kHz and a small 1" round horn (1.8 kHz). The 10" woofers Fs 59 Hz, Vas 1.30 litr, Qts .27, Qes .29 Xmax 4.9 mm Mms 28 grm, BL 14 Tm. As a DJ monitor and use an Eminence pre built Xover passive. Or even making the vent taller to 60 Hz tuning. I'll be putting a tophat at the bottom. The woofers are neo I want something light weight so may use Arauco 15 mm ply 5 or 7 ply for 18 mm thick. I am going to have it on the side of DJ table or in front of me. Thanks!

hi there all, i am a reggae/dub head and would really love to take this up as a
project, but the only thing is im not to handy with wires or speakers, if there
is anyone out there that has a good knowledge of what loudspeakers/tweeters and
every part of electrical goods i will need for this build i would be hugely
apprehensive if someone could make me a list of stuff i would need to get to make
there work. thanks Oli
