Help me choose a new sub

If you're spending 500-600.00, look into VMPS subs--awesome sound, not for the money, just awesome sound--deep, powerful, clarity, no boom, adjustable to any room to get great sound. They will also blend with very fast speakers and be unnoticable in location sound wise. They have more expensive ones also that are even better.

Thanks so far - i'll look into VMPS as well. Just wanted to add to my list the elemental designs A5-350.

get a JL L110 used for a grand
you'll thank me later

Get a used SVS PB13 Ultra for $1200-$1300 that'll eat three JL F110's for breakfast as an appetizer, than thank me later..
