these sounded the best, all the other ones distorted the sound when bass got too high, but these didn't, im getting them in OCT, by then ill have enough money. and input will be greatly appreciated.

GO ON EBAY, you can get MB Quarts that will fit for cheaper
MB QUART is better

i know mb quart is better, but i don't wanna get ripped off, i wanna play it safe, although most ppl who sell mb quarts have 100's of praise replies.but the ones that i was thinking about getting aren't up right now, im buying them in 3mos. so can wait

Use Buy it now, I have bought TONS of stuff of those companieso on ebay and never ever got ripped off, yeah go ahead and wait for those
