Just looking for an opinion/comparison on these three 6.5" component sets at Sonic Electronix:

$210 Polk MM6501
$220 RE Audio XXX6.5C
$270 MB Quart QS216

I'll have an MB Quart amp for them, a Pioneer deck, and a 12" sub (so maybe don't need super low bass extension, but I want enough bass up front to keep the sub from sticking out).

I don't really know where I can go listen to these speakers; I wouldn't be asking if I could. I listen to a lot of jazz, want clarity and smoothness with the ability to play reasonably loud as well. I'd appreciate any insights.
