I will integrate some JBL W15GTi drivers in a home system to replace some 15" JBL Pro studio drivers that are very high on sound quality, but a bit challenged in term of power at very low frequencies.

If I am looking for better sound (transients) over SPL on a 20Hz-80Hz band, what works best with W15GTi drivers? Sealed enclosure (4cubic feet) or bass reflex? The "kick" is handled by 4530 bins and 2225h drivers.

TIA

The sub triplets


The kick bins. Very efficient.

 

The EBP suggests those drivers will work well in either sealed or ported enclosures.. I'd suggest porting them at 20Hz..

wicked awesome subs i have a pair also i would say port the enclosure around 28hz or even seal them up will still be plenty of bass! geez i couldnt even imagine 2 of these in a HT setup.. the wife would kill me and the windows would be shaking

good luck with the build!
