The larger the room the less are boundary effects throughout the range, and the less obtrusive are bass mode effects (they tend to be spread out instead of bunched together).  Unfortunately the "no free lunch" rule means that such rooms require more bass energy for the same perception of power.

Outboard Sub to the rescue!

AK's Outboard Sub is ideal for larger than average rooms and/or to achieve below 20 Hz cutoff with AK SuperStand, which has a sealed sub driver and cutoff around 25 Hz.  Match any room and/or taste: plug one of the two ports w/included Cherne pipe plugs to flatten the bass bump, or plug both ports for sealed response.

When used with SuperStands, normally OS site one per each side wall, w/staggered distance from the front wall, e.g. L sub @ mid point on the wall, R sub 1/3rd or 2/3rds from the front wall.
