[Elecraft] OT: Speaker Wire Recommendations?

[Walter Underwood]

If it is a long run, you might use a 70.7 V system with Cat 5 cable. Put transformers on each end to run higher voltage (lower current) on the wire and use cheap, good twisted pair.

Another approach would be to use line-level over Cat 5, then put an audio amplifier at the speaker. I use a dual 15 W amp that runs off of 9 to 18 V.

Amazon shows the exact model at not available, but there are plenty of similar alternatives.

I've used Audioquest FLX-DB 14/2 with good success with a hi-fi system located literally underneath my antennas on the roof. You can get it at Crutchfield, or probably many other outlets, at a fair price.

I considered using CAT-5(+) wire and bonding all 4 pair to a single loop, but I don't think a single run would be enough copper (?), and I don't want to make multiple runs per driver.
