Speaker cables which bring out more bass?

Well, when I switched from Canare Star Quad 4S11 biwires to Audioparts Mas Hybrid Signature biwires, the midbass improvement was the biggest difference. FWIW, here's a link to my review of them:

Mas Signature Speaker Cable Review

It should be pointed out that these would probably be considered by many on this site to be "entry level" cables. I really like them a lot, however, and several other Audiogon members do, too.

The best speaker cables for bass I've heard are made by Virtual Dynamics. They come in a wide variety of price points and are not inexpensive, but they sure let the sound through, comparable to a live performance.

Hope this helps.

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.
