I received an LFM-2 (and an RR-2150) on Friday. The sub is working great, but it doesn't look like the one on the product page, which appears to have a black top. Mine has a manila folder colored top. In fact, that's what I thought it was when I unpacked it. An attempt to remove the 'folder' revealed it to be the true top of the unit. When I look at it, it just makes me think of a kid's crazy summer haircut, with long hair down the sides but bald on top. Is this the way it's supposed to look?
