Long run speaker wires


Would like input on long runs of speaker wires for rear speakers.

Speakers are NHT L5 monitors.

Currently I use Audience Au24's for front monitors and Analysis Plus Oval 9's for two subs.

Need to wire inside walls/crawlspace for approx. 30'

Any ideas?

Thanks!

Sternsn,
I ordered the AudioQuest GBC Deluxe SST 12 AWG Speaker cable sight unheard from the ad in Stereophile. I needed a 30' length in a hurry so had to take my chances, they are working so well I plan to keep what was a temp. room configuration permanent.
I bought some 40' Canare 4S11's from Bluejeans and I should be able to get them installed in the next week or two. I'll let you all know the outcome.
www.impactacoustics.com. I bought a bulk 250' roll of 14ga/4 for $99. This wire is rated for inwall applications. I have two 40' runs.
The Canare's sound fine to my ears on the rears. They are pretty thick so the installer was not too happy.
