They sound good, I dont have mine sealed so I couldnt tell you about the midbass. I do know that they have alot of excursion though, which might mean that they have good midbass. There is slight distortion, but I think thats because I dont have them sealed. Other than that they are great comps.
I wouldn't push then that hard, the rms on the mm6.5 are 150 but i'd give then 125 or a little lower. because you figure your cd reciever is probably giving them 35rms if you have a good one
nice drivers, well engineered and sound quite good. can be had for aroudn $200ish shipped, and thats not ebay either - pls dont ask where, but i did see them for the $200 on the net......check a company in the 'current company list' sticky, should be there somewhere.
for the money - not many other combinations will beat it outright.
i however, prtefer morel audio drivers to anything heard so far.
We have the 6.5 coax and 6x9s at work, they sound great, better than Infinity Reference components and the Polk db components. They play lower than any other speakers of the same size at work (Circuit City). I was thinking of getting the MM6s but I decided to go with Infinity Kappa Perfects instead but that's only because of the setup I'm going to do (the Perfects in kickpods, MMC650s in the doors, no rear speakers, this is so that the speaker frequencies differenciate more). You could probably get better for whatever price you'd be paying though but I get mine at below ebay prices. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
