i also thought he mentioned better sounding, i'm probably wrong. OP, what kind of box are your L7s in right now?As I recall, he indicated that they went lower in frequency, not louder.
that can be said for almost all subs. That is why it is important to know what kind of ported box the OP is running. A prefab would def. mean that the box is tuned too high.Fair enough.
Some Sony subs do offer a decent SQ, even the Xplod models. Just have to pick the right parameters.
Please don't do this. It will only complicate things further.l7's are crazy loud, but I just hooked up my sonys to the kicker amp. they hit so much lower. so I need to build a new box for the l7's or build a box for the sonys so I can have 2 12" l7 3 or 4 sony xplods. that way I can have the high bass from the l7's and the really low notes with the sonys.
on a side note my kicker zx.1500.1 can destroy 4 1200 watt sonys turned half way up //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
