A decent sub for minimus 7's

Sorry, on the road for work the last couple of days. Not room lift, the speaker itself. The 7 has a significant rise at the fundamental resonance of the woofer in cabinet. RS did this to get away with a small cabinet and trick your ears into believing there's more deep bass than a meter would confirm. By crossing over above the rise (don't recall the amplitude) the high pass section will pull it down. Cal's suggestion does effectively the same thing, brings it down about 3 dB at 125 Hz (depending on x-over type: passive or active) and results in a roughly third-order acoustic high pass from the 7's at that frequency.

So here's what I understand so far:

I can esssentially run a decent sub with the speakers, x-over at 125Hz, and not suffer too badly for it? If that's the case, great! I'll worry about audiophile playback later (read: after graduation). I've noticed that the system sounds better than any HTIB setup I've heard so far, so I think this will suit me for now.

If I've got this screwed up, let me know!

I've also solved my single RCA jack into a pair of jacks question. I went to Radio Shack and noticed that they've got the y-adapter for sale. Forget about kludging my own. Now I'll focus on some of the tweaks I've read about.

Thanks for all the help I've received here.

Keep in mind that the LFE channel from your receiver probably has its own lowpass.

You're right. It has a low pass at 120Hz. I should still be okay, right?

Then you may want to defeat or at realize that the 2 filters will cascade when you are playing with the XO settings...
