cables...Shielded vs regular speaker

[eastcoasteddie]

is "shielded" cable a different animal, or is a high quality speaker cable shielded?
Why do you need "shielded" cable for bi-amping cabinets, the cable between the low/high output and the power amp in connection.

Never played with bi-amping until now...help a bi-amp noob...

Speaker cables should NOT be shielded in that respect - among others - they are different than either instrument or line-level cables. I take it you refer to the patch cables between crossover outputs and power amp inputs ... those SHOULD be shielded.

Shielded cable has an outer conductor that shunts external electrical noise to ground. This is generally used for very low voltage conditions where ambient noise can a large percentage of the signal, such as between the instrument and the amp. If noise is picked up here, it will be amplified to many times it original value by the preamp and power amp. It's best to use sheilded cables on everything up to the power amp output. At power amp output ambient noise is so small compared to the signal as to be negligable. Here, large conductors are needed to handle the power going to the speakers. There is no need to shield them.

Further more it's BAD to shield them - it's BAD - it's bad! ; }

can you give me a brand name or a part number of shielded cable I can buy. I did a search on Musician's Friend, and didn't come up with any shielded...
and yea, I'm refering to the patch cables from Bi-Amp Low or High frequency OUT to Power amp IN connection, as in the SVT4Pro rear panel (or whatever amp has bi-amp capability.

All instrument/patch cables are shielded, most speaker cables are not.

if a cable is labled "Low Noise" on the insulating jacket, what are the chances it is shielded?

SPEAKER CABLES are sold as SPEAKER CABLES. The others are not. You aren't shopping at Walmart, are you? ; } - Get thee to a decent website that specializes in cables if you'd like to understand all this better.

no, I don't have a Walmart for 50 miles from me...

Darn near 100%. Noise isn't an issue with speaker cables.
