Hello all, what's good..

I have been running a 2005 RE xxx 15 in a Powered for Sound snail shell enclosure for over 3 years off of a hifonics brutus bx1500d at one ohm. I am pretty sure this enclosure has a tuning of somewhere around 27-28hz...This is the frequency range that my subwoofer moves the least at when playing sine waves. I think 28hz is also the FS of the 2005 xxx 15.

Anyway, I am tired of the overly-loud, and sometimes sloppy bass that ported enclosures offer. Time to go sealed.

I am going to be using the amp I already have, which provides 1500 watts at one ohm (some claim overrated). After some research I have decided on the following possibilities:

- 2 dual 4 ohm Alpine type r 15's, which according to the parameters, are well suited for sealed alignments. They would be going into a 5.5 cubed gross sealed enclosure

- 2 dual 4 ohm rl-p 15's, which would go into a 6 cubed gross sealed enclosure.

- 2 dual 4 ohm JL Audio 13w6v2's which would be going into at least a 4 cubed gross sealed enclosure.

- 2 dual 4 ohm Elemental Designs 16ov.2's which would be going into about a 4 cubed gross sealed enclosure.


What does anyone think? All opinions are welcome.

not all ported enclosures have overly loud sloppy bass
Snailshells have a tendancy to behave in this manor

anyways good luck with the SQ set up..I recently
changed to SQ myself...couldn't be happier

why not go with 10" or 12" woofers if you are going for less boomy tight bass???

If you're looking for sq woofers none of the one's you mentioned are very reputiable for their sq. Maybe the Alpine's, but I would focus on a driver that is ment for your specific application. Something like a Focal, B&W, or O2 subs. I know that there are more high end drivers out there, but I am not interested in them myself and can not provide you with many of the companies that make them. This is an spl forum so it might be kind of hard to get any s

sorry i hit enter before done. It might be kind of hard to get any sq advice here, but maybe try posting under the sq section of the forum. Good luck with the install.

Boston's G3's are a GREAT sounding sub. If you want SQ, I'd step up to the G5's though.
The 13w6v2 is going to be better than either of the boston's.
