    Default Multiple subwoofer setup and bass management help

    I was wondering what anyone suggests for bass management with 5 dedicated subwoofers? also, I would appreciate suggestions on how to set all five with an SPL meter. Thanks.

    Welcome to the Polk forum.
    Rather vague question. More info might help. Why 5 subs? Do you have an enormous room? Are these passive or powered subs? What brand/model are they? Are these for a home theater or 2 channel music system?

    Are the subs passive? If they are then I would suggest DSP enabled amps from the likes of Peavey, Crown, Behringer, QSC, etc. Also a Dayton Omni-Mic.

    I'm assuming that if you have 5 subs you have decent budget but don't want to assume too much.

    Multiple subs scattered about the room is the new thing.

    Doc Earl Geddes did a recent talk at a hi-fi club.

    For those curious about Geddes "Multiple Sub" technique view this Presentation or the PowerPoint.

    You need to have the PowerPoint open to follow along with the video. (but it's a 'pptx' which may be a problem for some)

    The video doesn't give the solutions, but it does show the path.

    I would say that is overkill for the bass part of the subs

    For most music it is.
    But for serious home theater buffs and techno/trance/dubstep DJs and fans, it is just barely enough.
    All comes down to personal preference.

    Would be nice to know your current room layout, receiver, pre-pro, etc...

    You can never have enough bass!! If I have the room, I'll continue to add more subs!! I just love having the slam felt in any part of the room.
    I'm gearing up to modify my PSW1200 into something with more of a punch! I'll need some guidance from you guys though.

    I agree that when it comes to subs, the more the merrier! The more you have to place in a room, the smoother and accurate the bass is. All the subs are powered, but the complicated issue is that my centers and mains are also powered.


    My setup:

    Living room
    Onkyo tx-nr 5010 receiver
    Onkyo pa-mc 5500 amp.
    Definitive mythos st mains
    Definitive cs 8080 hd center
    Definitive studio monitor 65 wides
    Definitive studio monitor 55 heights
    Definitive sr 8080 bp side and back surrounds
    Definitive sc 8000 super cube subs (5)


    family room
    Denon avr 4520ci receiver
    Polk rt 2000p mains
    Polk cs 1000p center
    Polk ls/fx side and back surrounds
    Polk psw 1200 subs (2)

    I plan on updating my Polks for the family room HT to utilize 11.1 channel sound.
