JL makes many different subs. From entry level to high end.Congratz on your new ScanSpeak sub, not so good for JL Audio since i heard and had the idea they were the best sq subs out there but after reading all this, you got me thinking twice. lol.....
I do have a few question that i hope you can answer:
1) A good quality subwoofer that only needs 175w Rms feed can play lower notes/more quality bass inside a vehicle than another sub that requires 250w Rms?
2) which of the two would be louder though?
3) How can you take freq. response into account and bring it into the mix with the previous questions to get the best quality bass in a sealed box that does not disturb the neighbors but instead fills your car ?
