    Excellent value and quality

    Overall: 5 out of 5

    I bought 4 of these for the 2 front speakers in my home theater system. For each speaker box, I wired 2 of them in serial to make an 8 ohm load.

    This particular project took a little over a year to design, purchase parts for, and assemble. The results were worth the wait.

    The sound quality is excellent, with window shaking bass. MCM could easily charge double what they are for these, and they'd still be a bargain.

    The speakers arrived in perfect shape. I couldn't be happier!

    MCM doesn't know how to pack things

    Overall: 4 out of 5

    The woofers are good except they're all glue construction (expected) and the surround overlaps the mounting holes. I wired 2 speakers per channel on my 100w stereo in series to get an 8 ohm load and tested them with no box and they were moving pretty well. I'm going to build a box in the next few days to see what they'll really do, and maybe put them in my car for fun. The shipping was bad. I ordered 4 of these and some speaker terminals. The 4 woofers came in cardboard boxes with no padding and were packed into a bigger carboard box just large enough to fit the 4 smaller boxes. If they had rough handled it at all there would be a fairly large chance of damaging it. My speaker terminals were packaged in a brown envelope with bubblewrap on the inside. The metal tabs on the back of the terminals are all bent and one was even poking out of the envelope when I got it. It's no huge deal, they'll straighten out, but it's annoying how bad they were packed.
