Used MMG's

Personally, I wouldn't think about buying MMGs used unless I was at +/- 50% off. OTOH, if the savings on this offer is the difference between go/no go on your purchase, I'd think hard about pullling the trigger because these are really fine speakers at their price point.

Just make sure that you're comfortable with the realities of the MMG: limited deep bass, limited max SPL output, significant power requirements, and breathing room to the back wall. If you buy new, you get a test run - but that's not the usual deal on used gear.

Good Luck,

IME, you're right at the margin. I'd say that you need three feet and change to feel comfortable predicting success without much reservation. But that doesn't mean you're doomed here - there are just too many room specific variables at play to make a confident prediction. If you're buying new, just give it a shot and see what you think. You can always send 'em back if it's not working to you're satisfaction.

One more thought: The MMGs are pretty happy close to the side walls. You might think about placing them along the adjacent wall if your decor allows and it would allow you to provide more room behind the speakers.
