Bi-wirring long run rear surrounds


I recently purchased canare quad 4S11 speaker wire to biwire my (B&W 805's)surround speakers. The runs are long, 35 feet and 40 feet. I was told at a high end audio store that biwirring long lengths wasn't a good idea. It would be better to use two cables per speaker post or doubling up. Any one have opinions on this, I don't know which way to go.

Gaswho52, I am running B&W Signature 7NT (in wall) speakers for my home theatre side channels.

After they were installed I experimented over several days, using two tube stereo amps in mono mode, both cables were run to the jumpers at the crossover of each B&W speaker (non bi-wire with jumper in place).

Next I removed the factory jumper and ran them as bi-wire, using four separate channels, making it bi-wire and bi-amp as well.

The results were much better with bi-wire plus bi-amp. Not certain this applies to your question as you may not have four channels of power available.

The only concern would be your run is too long for the conductor size (gauge). My runs are about 30 feet using Purist Audio and each conductor is 12 gauge (X4).

Let us know if you experiment and how it works for you. Would be of value to myself as well as other members.
