VLA
 
Bass option II comes in a new 6ft tall powered woofer column we call the VLA (or Very Large Array) with four active 12" megawoofers, and one 12" Passive Radiator.  It also has one side-firing 15" Passive Radiator.  It is very heavy, over 300 lbs, is standard with 1000w amp/crossover, and is priced at $4960ea.  Use one or two.
 

"Use one or two" as prescribed by Dr B? Do we have the usual caveat that they may be addictive and side effects may well include disorientation, euphoria. loss of sense of time and place, etc???  :scratch: :scratch: :scratch:

Yes, Doctor Cheney says "take two" and see if your bass problem goes away. aa

The two side 15" and the one bottom 12" are all passive.  Basically you need approximately the same surface area of PR to vent the four active 12", but this varies depending on moving mass of both the actives and the passives. 

The VLA will end up with at least one 12" and one 15" PR.  Or it might have two 15" PR and no 12" PR.  Or it might have all three PR's, two 15" and one 12".

We shall see.

What is the Xmax of the passives you are going to use?  In addition to SD you'll need lots of displacement.
