  • "MCM doesn't know how to pack things" by Cole G on 9/7/2013
    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.
