I guess I don't understand what you are trying to accomplish. Most modern receivers will allow you to change phase, and once it is set properly, why change it? The same with volume control. You want to calibrate your subs to your mains, whether that be even, cold, or hot. I do understand the need on rare occasions to bump the output a bit for certain movies, but that doesn't happen a lot. The only thing I could think of there is either use an SMS1 which has a dedicated sub volume control and DSP function; thereby killing 2 birds with one stone, or setting up a macro in your remote that would allow you to access the speaker levels in your receiver bumping them up or down as you see fit.
Also, you discourage a triangular box. Is this just due to build challenges or is that shape sonically deficient? Thanks again.
Well a square is a lot easier to build than a triangle for sure. There are a lot of angles to figure to get the joints to line up properly.
Also keep in mind a triangle will need to be a little bit larger in all dimensions to match the cf of a standard square cab. If only going with a single driver it's probably not a huge deal but for reference; a 4.29 gross volume square cab will need to be 21" cubed whereas a triangle one will need to be 26.5" cubed. You also have to take driver mounting depth into consideration based on the triangle shape.
Other than that, go for it. Edited by bass addict - 2/10/13 at 10:47am
