those MCM paper cone cloth surround units are GREAT bang for the buck. 4 8's in my livingroom, couple of their 12's low pass filtered in cabs being driven by a warmed up Lepai 2020A+ amp (now 13 honest watts instead of 8.3).
your soundboard wont have the power to really push that 10, which really wont matter, you'll feel it plenty.

I dont doubt that MCM 10 one bit, give it maybe a week or so to break in and loosen up too btw, the surround and spider might be a little stiff at first. hook it up to a stereo and feed it 25-30w a few hours oughtta loosen it up nice enough too. she's gonna BOOM even though not being fed anywhere near power capacity.

nice. a few had questions about it being 4 ohm speakers, not much an issue when you can pick up a couple 2-4 ohm 20w resistors to put in series to them, or larger value if the backbox speakers are too in your face loud. adjustable with L-pad can be nicer but good balance with just resistance is doable.
