Opinions on the Bose 901

A friend of mine just gave me an old pair of Bose 901 Series IV. All the foam surrounds have crumbled, but the cabinets and the EQ are in decent shape. A foam surround kit plus the dust caps is less than $90 USD at ( www.partsexpress.com ).

I am pretty much set with my Swans M1 near field system--it rocks, especially after adding a 3000W ONEAC 220V isolation transformer. I am looking at using the Bose as HT speakers or as a background music system--I like to have music all over while I cook...

I am seeking unbiased opinions as to how I could use these speakers in a 2 channel HT setup:

The Series IV has a third contact between the (+)and the (-)(is it a ground?) which was used with the Bose Receiver's "spatial control". It allowed changing how much energy was sent towards the inside or outside reflecting surfaces--it was like a fader control, but from inside to outside.

If I use them for HT, I could use a homemade preamp that would allow such control and the 901's could become a "virtual center channel" by shifting the energy balance towards the area between the speakers. I think this could offer a neat movie viewing effect in the absense of a Pro Logic, THX, DTS, 5.1, 7.1, 10.2 or a 15.3 decoder.

A false gypsum wall could be constructed for having my 27" Sony WEGA flush and provide a good reflective surface for the 901's.

I will appreciate any constructive input.

Thanks,
