ok well, I'm gettin a killer deal on some focal 165k2's and mb quart Q 218.61's...I had originally planned on getting infinity kappa perfects. I'm just wondering how do the infinity's add up to each of these? on ebay the focal's and mb quarts are 100-300 dollars more than the infinity's. But I've never heard either mb quart or focal, I have heard infinity's and I love em, can I expect better from these?
