Stacked woofers

dsrviola · 15th October 2006, 02:11 AM

What problems, if any, are involved when vertically stacking 2 (or more) woofers (this is for a 3 way)? Do the drivers load the room differently? Can this create a peak in the bass response? Anything else I should watch for? Prototype Version 1 of the speaker I built currently uses one bass driver, but I want to implement 2 woofers since Version 2 is going to have increased midrange sensitivity.

TIA

You'll run into problems with dispersion and comb filtering if your crossover frequency is too high. If both woofers are within one 8th of a wavelength at the crossover frequency, then you should be in great shape. If the rule of thumb is some other fraction of a wavelength, I hope someone steps in to correct me.
