[QUOTE="Jimi77, post: 8839117, member: 673702"] w7s tend to sound boomy and muddy ported. It's a high Q, low FS sub, so it's going to sound boomy in the recommended ported enclosure. Given typical cabin gain, the enclosure alone puts you +6-9db at ~40hz. If added any bass boost, then that only makes the problem worse, so make sure bass boost is off.

If you have an EQ, try tuning 40hz down ~6db. You can try something more like 2cuft ported and tuned to ~25hz to take some of the boom out of it or maybe ~1 cuft sealed, but either of those enclosures will cost you output, considerable output in the case of the sealed enclosure. The ported enclosure will be tricky and big due to the low tuning frequency, so you might have to consider a passive radiator design. Go sealed and you'll be wondering why your w7 is barely louder than the cheap JL on 1/4 power, but the sub will sound much much better. [/QUOTE]
