OK, need a little side wall 'breathing' room, so 18.5" W x 13.5" D x 46.5" H [i.d.] = ~6.72 ft^3 - ~0.33 [604] + a little bracing puts it ~ the prosound/studio monitor preferred 612's 6 ft^3 net, not the optimal ~9 ft^3, but big enough tune to 35-40 Hz [most common tuning] if against a wall and even to Fs if there's enough room gain with any windows, doors closed. wink

Still need to know the preferred ear height for driver location and forgot to ask what amp will be used.


Presume there's no other considerations..........
