Well, this should be funny if you pull it off. If you discuss your 2.1 stereo system hooked up to your computer with some one who really knows their audio/HTequipment, I would like to see their expression when you tell them you have an HSU sub in the mix, Ha! Would you like to tell us which model HSU you have?

Actually I don't see why it wouldn't work except it might be a slight bit of overkill on the sub. I'm not so good on the cable flows but I think either a y-splitter or one with an A/B switch like you might get from Radio Shack would work fine. The HSU people are great and I'm sure they would give you the definitive answer. I presume your current HT system is using the sub crossover in the receiver.

That Sony model number sounds like it might be an entry level receiver and not have a selectable subwoofer crossover frequency. It might be set to a defualt at 100Hz or so. Sony should be able to tell you, maybe. Some receivers do not have the sub active in the stereo mode and you have to have the input mode in auto select or whatever they call it to make the sub active.

For the speaker if you can go 1.7 inches deeper then this Athena might be great. It is discontinued and a great price and very good sound. Several other options below.
