I tried my best to seal and dampen the door, but also have some improvements to make in that department. I have a 15" Fi BTL-3 powered with a Crescendo S1+. An Mmats 6150 6 channel power the speakers. No real fill. Helix Dsp.3 My box is 4.5 cubes ported bass reflex designed specifically for the sub, to try to maximize the linearity. I know its not a SQ sub, but I'm still trying to wean myself of the basshead lifestyle. :-)
I would honestly like to be able to do both styles with my setup one day. 140-150 in spl and a true competition install and tune for SQ. Not necessarily the same tune, but the flexibility to do both.
Edit: Power is 25oorms on sub and 100rms on each other driver.
Crossovers sub 80, woofs 80/375, mids 395/3950, tweets 4200. I set these after expanding them very wide to find where the speakers roll off at. It took a few tries to get the sound right, since my woofs and tweets can be used 2-way, but I added the mid to the set and make it 3 way. Polarity I checked with tones and ear, just seeing if flipping htem made a difference-it did not. Finally, I measure using a Behringer mic I got cheap and an old SPL disc with clean pink noise. I do this with my volume set to 32/35 - the same volume I use to set my amp gains with a DMM.
I love the input!! Please keep it coming!
