Whats wrong with short cables?


Hello Fellow Audionuts!!!!

Just curious....

Why should speaker cables be 8 feet and over? I hear that sometimes shorter cables can cause blown tweets and such during extended guitar solo's and stuff like that.

I always kinda assumed the shorter the run the better.

Im researching into building my own Pre, SS Amps, Speakers, and cables. I was planning on running a stereo amp pair for each speaker and bi-amping them. The amplifiers will be on thier own stands between the pre/cdp/tuner and the speaker. That means i will have a speaker cable run of probably less than 4 feet.

Would it be better to tailor the legnth of the cable to the distance needed? or would it be better to use a cable over 8 feet in legnth and just have it coiled behind the speaker?

Nothing is wrong with short cables, IMO. I run 6 foot lengths to my speakers. . .always have with excellent results.
Yes, shorter is better, and the LAST thing you should ever consider doing is coiling any leftover! Nothing like a high-pass to ruin your woofer's bottom octave....
The consensus among the experts such as Martin Colloms or the designers at Audio Synthesis is that the speaker wires are the weaker link. I have found this to be true in my experience. Pierre Sprey at Mapleshade has the opposite opinion. I know Pierre and his opinion carries weight so I have ordered a pair of his speaker cables to see. The whole question may well be system dependent. As to the short cables causing tweeter damage, I have never heard this in 42 years in audio. It would seem to assume that(1) the amp would somehow be unstable without a sufficient length of wire to load it, or (2) that without a longer run of interconnect to attenuate the treble the signal would be too strong. Neither seems likely. Stan
Most speaker cables are deficient in design and using a longer length gives you more of a problem. By keeping poorly designed speaker cables as short as possible, you redue the effects that they have on the system. As such, the logical deduction would be that longer speaker cables = lower performance. This is true when you start off with something that is sub-standard to begin with. If one were to purchase "real" speaker cables that are correctly designed, you don't have to worry about running longer lengths with their signal degradation creeping in. Sean

The Science behind speaker cable technology
Subaruguru...I vote for short cables, like 1 foot with the monoblock amp adjacent ro the speaker. However, if you have too-long cables that need to be tidied up, coiling them can be OK. First of all, the air-core inductor created by coiling several feet of cable would be of very low value...especially for the woofer signal which goes directly into a large inductor of the crossover network. Furthermore, for the perfectionist, you can coil the wire in the same configuration that non-inductive wirewound resistors are made. Make a large loop of all the wire you want to coil, and then wind the coiled (2-wire) loop. tightly.
