A bit heavier than I thought, or rather had it in my mind it’d be slightly heavier than the regular Motion Series cube surround speakers but not this heavy (16.5lbs).
But nonetheless these hefty surrounds mate perfectly with the rest of the Electro-Motion series line of speakers (my EM-ESL front left and right, the C2 center). Crisp and smooth and clear.

I have two pair of these speakers for surround side and surround back’s and they are awesome! Room is 15ft wide and 18ft long and they are perfect for the room size.

Excellent surround speaker. Can’t wait to buy another pair for my left and right surrounds. BTW, I am a big fan of B&W, but I have to admit that, after I replaced my B&W left and right back surrounds with ML FX2 ones, the difference was phenomenal in terms of details, and richness of the sound. I would definitely recommend ML FX 2 to anyone building a dedicated home theater.

These are very good speakers, but you really must have a huge room to use them as surrounds.

Amazing speaker experience. I bought a full set Martin logan home theater for my media room. Just amazing quality of sound. Loved it

I bought these after returning a pair of Motion FX’s to supplement my Motion 60XTis, Motion 50 XTinand Dynamo 1600X. These sound super rich and provide excellent imaging. Their build quality is also great and they look cool, although a hit bulky. Overall, I highly recommend these if you’re looking for surround speakers.

These speakers are great when used for surround channels. Very clear. A noticeable upgrade from the MotionFX speakers priced $300 cheaper.

Wow! This is a gorgeous speaker by Martin Logan. It’s great for surround and with its thin profile it hugs the wall nicely. It looks premium and sounds great. I recommend this to all audiophiles!

Love these speakers. Purchased these speakers. Returned them. Tried another brand. Returned those. Purchased the FX2s again.
