Thanks for the input (you too, M5). I'll experiment more with various settings below 100Hz and see how that works out when I don't need to worry about waking anyone up heh. And yeah, I agree. I like to keep the mains right on the subs. These are in separate boxes =) Thanks again.

It's a rackmount 3-way crossover. Not using these in a car hehe. I think which proper crossover points and filter types to be used are independent of the crossover itself, in that the same type of filter with the same cutoff on two different crossover models really wouldn't make a difference, except differences unrelated to the filter itself. No? Thanks.

Hey guys! I was wondering what any of you with a Q 18 set your crossover or lpf to? Also what type of crossover? Right now I have BW and LR filters to choose from, 6, 12, 18, or 24db/octave and 12 and 24db/octave, respectively. A simple frequency recommendation would be great though, hehe. I have tried many values from 70 to 180Hz but can't really decide. Are there any tests I could do to help me decide? Right now I have it at 127Hz 24dB LR which seems to be fine but I still feel indecisive. Thanks!

Thanks a bunch!!!

Does anyone have the specifications for the last model of the Q 18? I no longer have my saved WinISD profile, so that would work as well. Thanks!

Not every box will be the same so neither will the results. The smaller the box, the tighter the bass response. The larger the box, the boomier the bass will sound. I think polyfill is intended for smaller enclosures but Ive never used it personally. It makes it seem as if the enclosure were larger than it really is. Thank you for your reply. I had read somewhere that a smaller box would result in a boomier sound, and it also looked that way using WinISD, but didn't look to be that much different from a larger box. So by tighter bass response, what exactly does this mean? Thanks again

The recommended box volume for a sealed enclosure is 4-8 cubic feet. Is there much of a difference in sound quality from 4-8? What exactly would be the benefits and disadvantages of having the volume be 4 cubic feet to 8? What about 5 6 7? So far what I could gather is there would be less low-end with the smaller box volume but the bass would be more detailed. Is this necessarily true? I have trued modeling the a box with WinISD but it didn't seem very useful to me. Also, would adding polyester fiberfill be useful in a larger volume box? Thanks!
