[QUOTE="audioholic, post: 7289312, member: 549629"] Kicker has moved in a direction that does not fit my tastes. Kicker has always been notorious for leaning more towards output oriented products than towards SQ ones. But this trend became too wide for me to really appreciate their 'top of the line' subs when they went to the square design. Square subs. By now, most people here already understand the design problems inherent in square cones. The corners are further away from the t-joint, where the energy/motion from the voice coil transfers to the cone. And the centers of each flat side of the square is closer to the t-joint. This means uneven forces around the edge of the cone. This uneven force/stress will tend to want to make the cone's shape warp under high excursion. The way Kicker offset this problem was to add those huge ridges in the cones (thought they were just for looks?). But this fix adds to the moving mass of the driver. Round cones' shape makes it completely immune to this problem. But you say that price is payed in full by the added benefit of more cone area, right? A 12" square cone approaches the cone area of a 15" round cone. But, the square coned sub also requires a larger enclosure than the average round 12" sub. You dont just get that added cone for free, it comes at the cost of requiring a larger box, just like adding cone area to a round sub. So its my view that if I want a sub with the cone area of a 15, I'll just buy a round 15, not a 12" square. Square cones really only have two, fairly obscure, true benefits over round cones. One is in the event you dont have the height on your baffle board to accommodate a 15" round, but you do have the 12" needed for the square driver (and also have the space required behind the driver to give it enough internal volume). And two, if you are building a wall in which you will literally butt one sub up against the other, squares fit together much more efficiently than circles do. The CVX is a decent sub, but for years Ive hoped Kicker would come out with a really top notch round sub, and take emphasis off their square-cone-marketing mentality. I rememebr when Tracey from Kicker use to frequent this board, I thought I had him convinced to make that happen (and name it the audioholic series muhaha), but it just never happened. [/QUOTE]
