I am currently refinishing my basement. It is 21'x26' with 10' ceilings. It has a concrete floor and ceiling with cinder block walls. Along the walls I will have arcade games, and I have a 135" projection screen with a couch. I need to be able to wall or ceiling mount the fronts, center, and surrounds so I was going to get 4x CBM-170SEs, a CBM-170 SE C, and then a sub. I am debating between the L22 and the LVX12. It's a large room with very hard surfaces. It echos like crazy right now but there is nothing in it yet. I am still finishing the flooring, painting, and electrical. I will be adding a few large rugs to help.

Any advice on the LVX12 vs L22? I'd like to go with the larger CMT-340s but I need to wall mount them. Will the CBM-170SE be adequate?

Thanks
