You need the EQ either in a tape loop, or if your receiver has pre out/amp in, you can use that. The 901s are designed to be used with the EQ.
Bose 901 VI flat?
I purchased a pair of Bose 901 VI speakers recently and a new Sony STRDH190 receiver. I have wanted these speakers for years and finally got them. Problem is, they sound flat and weaker than expected. I adjusted the bass and treble to my liking but that only helped a little. I have the Bose EQ that came with the speakers but i'm not using it due to new receiver technology. Am i doing something wrong? I know these are great speakers with a great history.
