Another point mentioned in the past, and might matter: If you biwire, use two independent cables. Biwiring in one cable negates many benefit. (this was mentioned several times in different threads.A TWEAK. to improve coherence, add a JUMPER to the negative posts. (so you have two cables, one to low from amp, one to high from amp, and then a small (can be thin, size is of no importance) connecting the two speaker negative binding posts. Oddly connecting both plus and minus does not improve it, nor does connecting only the two plus posts.
When I had the option, biwiring did improve clarity.
