Speaker cables which bring out more bass?


I need a speaker cables which bring out more bass. I want to use these in biwire setup only for bass section together with monocrystal silver cables in mid and hi section. I believe that pure copper must be best for transfere bass but I have no opportunity to test different brands before buying. So I want too hear about all Your experiences regarding this.

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.
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.
Thanks for Your all responses.
Shadorne I have floorstanders and the bass lack is not so big. I don`t want to use the sub either because of my room. So my point is not to increase bass. I am just looking for cables just for bass section that can do this job better than some other cables. I know that cable is passive device and it can not add something. Different cables just have different sonic signatures and I am looking for a cable with little emphasized low end.
Mapleleafs3 As I know the biwire usefulness also depends of crossover designs. You are right that on wery many speakers the two pairs of binding posts on speakers don´t benefit from biwire but sone designs do. I can´t use my cable anyway because the conductor size is too small for low end.
