I have my eclipse 12" sub in a .85 cu. in. box (recommended for boomy bass). and I am not too impressed with the sound I am getting from the sub. theres just some lows that it is struggling to hit. its running on a PG xs2500 amp. Ive used insulation before in my old system. would polyfill make a difference? or should I try building a bigger box, if so how big? any suggestions would help me out a lot.
