I was just wondering what peoples opinions are on sub size for SQ

The one that performs it's best in the room you have, and can handle the power you need it too. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'd definitely say, 17" has the best sound quality.

No, seriously, there's no answer. The sound tuning of the sub and box combo matter a lot more than the size.

- If you want tight sound, go sealed, that has the best transient response. And don't even think about a bandpass!

- For low distortion (clearer sound), more total cone area is better. This could be one big woofer or several smaller ones.

- For low distortion (clearer sound), you want a long stroke woofer. Usually the 12s and 15s are best.

- For low distortion (clearer sound), look for a design with an extended or T pole, a shaped pole vent, and a magnetic circuit optimized to saturate the center pole.

My friend designed the Alpine Type Rs following all those ideas. I don't know about other woofers out there.

i agree with most of your points, but this is a misconception. transient response is a function of box alignment...no more no less. a sloppy sounding sub is sloppy b/c of inductance, NOT cone size. i have heard many ported boxes that sound identical to sealed boxes (as far as sq), but they had balls down low that the sealed boxes didnt.

ever heard a pair of brahma 15's in 6.6 cubes tuned to 30 hz off 2200 watts? tight as hell, and painful when cranked.

i tend to prefer 15's or 18's...and i port them if i can //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'm considering saving up for a pair of JL 15w3's or 18w3's....

but SQ is a huge concern. I imagine they would be just fine with a good install though
