Speaker cables which bring out more bass?

I find monocrystal cables have similar sonic attributes, so maybe you can look into cables made from monocrystal copper.

I am not sure how you could increase base with speaker cables unless you filtered the mid and high range.

In general, if loudness, EQ, room placement or a bigger amp can't do enough for your bass then I would suggest that the only practical way to get more base is to get a speaker with greater bandwidth or a sub (usually this means a bigger box).

A good sub can significantly improve bookshelf speakers bandwidth and fill a low end hole especially at low levels, however, there is still lots of energy in the 80 to 300 Hz range that a small speaker will have to deliver, which leads to a risk of higher distortion at higher listening levels as the small woofer excursion becomes excessive and ultimately unable to keep up with the sub output.

I used to have Nordost Red Dawn, bass as punchy and lean, try SPM, have more body, but still lean. Now, I am using Kimber bi-focal xl, they are bringing out more bass, full and weighty.

audience au24,or Paul Speltz cables.

Run a single cable. Bi wire is an area of Myth and Mystery.

The cable companis like it because it sells more cable. But in truth when speaking to many speaker makers, the reason for two post is to Bi AMp, this has merit. Bi wiring will not to anything for your system.

My speakers had dual posts when I had them factory upgraded they asked if I intnded to bi amp them I said no. So they took away the double post.

In blind tests no one is ever able to pick out bi wire over single wire.

Do yourself a favout buy one Good cable and jumper it.

The old Audioquest Midnight cable did very good bottom end. I replaced it with a home made cable with 8 runs of Cat 5 cable. Each run wrapped in teflon and then the whole cable wrapped in teflon and then a shrink wrap over it. Is better than just about anything I have tried.
