View Full Version : Box Efficiency
06-17-2007, 01:46 AM
Im trying to get a better understanding of the difference in box sizes. my next subs are 2 splw15"s..for quite awhile ill only be able to give them 750 rms each. my question is...should i build my box big to increase the efficiency of the power i have or should i build it small to increase the spl? im not trying to enter competitions but i want somethin that will rock my car. basically it has to be very loud but i dont want it to be peaky or sound terrible doing it.

Don't quote me but, from my understanding....The more power the smaller the box and the bigger the box then lesser power
Do about 8ft^3 NET at 35hz and come back with results

yes, the larger the box, the more efficient the driver will become....meaning less power to push it.
where did you hear smaller to increase spl?

i have absolutely no idea...didnt think it was true tho. anyways what happens if you give the sub too much room? i mean is there a point where bigger starts to decrease output?

yes, but every sub is different so there is no magic number.
Smaller box for higher SPL might be referring to the fact that SPL boxes can be smaller if you want them to peak at higher frequencies...not ideal for a daily setup at all...
