How Screwed Am I?

Disclaimer: I'm a newb but I am aware I didn't make the best equipment choices when I bought this stuff. My only defense is it was five years ago, I was in a hurry, and I didn't spend much cash.

I've got a Sony STR-DE845 receiver and a Bose Acoustimass 6 Series II satellite system (it's got single cubes, not doubles, and a passive "bass module"). Please, any ranting against Bose will be preaching to the choir at this point. I will indeed upgrade my speakers...later.

I want to get some bass out of my system, and the Bose bass module is godawful. So I'm shopping for an inexpensive (<$300) active subwoofer. The problem is that the satellites run through the bass module, and the super-secret Bose crossover is apparently set around 280 Hz, which is way high. Too high to use an active subwoofer or the receiver as the crossover. The receiver will only crossover up to 180 Hz, and active subwoofers around 120 to 180. So not only would I lose 180-280 Hz, but I might damage the satellites. So it looks like I need to keep the Bose bass module just for its crossover utility.

Finally I figured, hey, I'll just leave the Bose system as is and plug the active subwoofer into the receiver's LFE jack. But I couldn't find any stats on what where the LFE crossover is for the receiver. I've seen reports of 70, 80, 100, and 120 Hz for various receivers, so I assume it's somewhere in that range. My plan had been to buy a subwoofer that went pretty high (some go up to 200Hz) to try and better match the satellites, but it looks like no matter what its range the sub would be limited by whatever the LFE output fed it.

It looks like my only option (assuming I can only afford a subwoofer at this point) is to buy an active subwoofer, plug it into the LFE, and deal with the fact that there'll be a big gap of about 180 Hz between the top of the LFE (around 100) and the bottom of the satellites (around 280).

Oh, and I have one more question. Is my LFE output only going to work as the .1 channel when I'm playing a DVD in 5.1? Or will LFE output work for regular stereo inputs as well?

Any constructive comments would be appreciated. Such as, are my assumptions correct? Are my conclusions correct? Does anyone have any alternate proposals on how to solve this? Is my only option one of sucktitude?

Thanks,

I gotta agree with the "Sell the Bose" suggestion and add that to the budget.
Not sure how big of a priority surround sound is for you, but i reccommend selling the bose, try to get 4-500 for it.
Take that 300 you have and pick up an Athena Subwoofer as earlier suggested, then take what you got from the Bose system and see if you can score some Jm Lab Chorus 707S's. Excellent sound for the budget, im running a pair of them and honestly i like them better than my last 3 sets of speakers and one of those sets cost me 1,600.

From there you can save up for a center and surrounds if needed, but in the meanwhile a pair of 707S's and an Athena SUb with that reciever, even tho it is not "surround" will smoke that blose acraptimess system.
