Background:-
We have a small band (6 piece) and use the Ketron AUDYA for drums and arrangement while having a live bass player, live rhythm and lead guitar players plus 2 vocalists. We recently purchased 2 Mackie HD1531 speakers (sound great) and are looking into sub-woofer upgrade. We now have 2 FBT Promax 15Sa (active bandpass subs) which are great and clean ... until you have to cater to a room of over 150 people. Then the bass is lost.

We want to upgrade our sub-woofers to either QSC HPR 181 or Yorkville LS801p but still trying to decide. We do a lot of Reggae, Soca, Zouk ... etc (dance) music. Any advise or suggestion is definitely welcomed. We run our own sound from the stage using a Presonus StudioLive 24.4.2 and portability is a PLUS!

Also some inside information on the type of sub to get for our needs would help. Event types are mostly weddings, graduations ... party where people dance!
* Digital Class D amp (sound tends to fall apart when approaching limiting point)or the warmer Class A/B or H (heavier but warmer sounds especially at loud volumes)?
* Front loaded/Rear loaded horns (e.g the Yorkville/QSC sub) versus the bandpass (FTB - lighter but limited volume so will need more to cover say 500 people).

The Yorkvilles produce a great punch to the chest (but comes with a price in weight), but the QSC appears to be a 'cleaner and tighter' punch (but not as powerful as the Yorkvilles). Yes, we would like to keep it compact though as you can tell, that idea is gradually going out the roof!!

Also - as far as placing subs - is it better to have one to each side of the stage or to avoid 'dead spots' in the room and forgo 'looks', place both subs together on the same side of the stage?

Anyone?

Thanks,

AJ
