I have a Q-Logic dual 10" subwoofer truck box providing 1 cu. ft. capacity in each chamber with two Infinity 10 woofers mounted. I seem to get a little bit of sound reverberation (for lack of a better description). The sound seems to go on and on after the note has been played, like an echo if you will. There presently is no lining or stuffing in the box. I want tight clean bass, some music gives me that and some doesn't. Will stuffing or lining the box help and if you which do you recommend? Thanks

Ive heard from a lot of people including experts on this site that say to use polyfill. About the reverb effect, one of the things you have right I hope is the two speakers in teh saem phase? Since you have 2, if you invert the phases of one of the 2 speakers, that will cause problems too. I presently have a similar problem but I have only 1 speaker. Even though this might not be the most relevant qustion, which amp are you using to drive your subs?

1 cuft sealed is a too large for a 10" Infinity driver. Should be closer to 0.75 cuft. Adding polyfill will INCREASE the effective enclosure space, not decrease it. I recomend you add a wooden block (or some other suitable solid material) screwed or glued to the inside of each chamber to take up about 1/4 the available interior space. Then if you've lost too much low end boom, you can add polyfill to get a few fractions of lost size back. ------------- Support the12volt.com

Markcars, I am using a Sony XM-DS1500P5 mono amp. I've heard some negative remarks regarding Sony's amps but I'm not gonna push it as hard as some of these other guys, too old for that. The subs are wired correctly for a 2 ohm load. DYohn, Enjoy reading your posts. Articulate and your well thought out responses draw a very clear picture for us beginners. Cheers

bbusbee,
You're right about the Sonys. I've heard the same about them. When I went shopping for my own sub, all the Sonys I've listened to including the Xplods weren't satisfactory to my ears. Also I agree with your point about not pushing the subs to enjoy sound; real quality does not need to be too loud.
