The bose are truely an interesting design meant to create a mix of direct and reflected sound before the days of digital time delays. Unequalized, they have a haystack response as you would expect from the size of the driver, relatively flat from about 150-1kHz. Very substantial EQ is used which translates to a requirement for power at loud listening levels (200W/ch). You might give them a try as rear speakers in an HT system since they should really spread the sound around the room. In this application, you might even try them unequalized just to see what happens. Have fun.
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,
