Hi ClutchBrake,

I don't recommend wall mounting the CMT-340s. These are big heavy speakers with a large rear port. I am also concerned that they might begin to sound boomy if too close to a wall.

Why do you feel the need to have a speaker with a good low end for your rears? I honestly see no advantage to this at all. The HTM-200 are 3dB down at around 87hz (anechoic). In a room and against a wall, they will be 3dB down in the high 70 hz region. If you receiver is crossed over at 80hz, these speakers and your sub will sum to almost a flat response, which is exactly what is recommended.

What about using the 170s in the rear?

Feel free to email me direct of call anytime!




Good Sound To You!
