Just a note regarding REL. Judging from test results at AVTalk.com and HTshack.com (look under "forums" for "subwoofer tests"), REL subs perform very well on Group Delay tests ("fast or tight") but generally poorly for clean output at high levels at low frequencies. Most of these models appear to be excellent woofers but not great subwoofers.
That may not matter in most music set-ups. In fact, the Rythmic subs I chose involve a similar trade-off. However, the Rythmiks fare much better than most RELs at low frequencies and are cheaper, to boot. BTW, they are available in a downward firing configuration. Caveat: numbers may not tell the whole story. Still, when it came time to lay out my own cash, I went Rythmik. SVS was right there, but RELs never made my personal short list. Now, if I could just turn out to be right about all this....
