Long interconnects or speaker cable?
Hi there,

Im thinking of doing an active speaker thing, really just putting my amps and Marchand XOs next to my speakers, and want to know what to do about a 7-8 foot interconnect. Id like to do it DIY, like maybe a Kimber style Cat5 or something. What are my options? Is it sonically better or worse than keeping the electronics together and running longer speaker wires? BTW, I will be using an Adcom GFP-750 to drive them.

thanks amt

From my experience, it is definitely better to have long interconnects than having long speaker cables. I strongly recommend balanced interconnects. They don't need to be expensive. BTW, my system is an active two-way setup (using AMT-1 for mids and upwards)

Definitely balanced interconnects. I've always been happy with Belden 9451 with Nuetrik XLR, but I'm sure in the world of audiophilia this is a rather pedestrian solution.

Good information link. So it appears that balanced interconnects are the best bet for longer runs and that what everyone suggests. My Adcom has balanced outputs but the XO boards are not balanced as far as I can see so am I out of luck or is there a way to modify/adapt them?

If they would make all drivers dual voice coil, then speaker cable could also be balanced. Unless... does someone know a way to do that?

The output of a bridged amp is balanced :wave2: ,but at output power levels it wouldn't matter much

So far, all speakers I've seen lack a ground connection, so I'd say they're automatically balanced. At least from a CMRR point of view.

But then, what kind of EMI would you need to produce audible artifacts by radiating into the speaker cable (terminated by 8 Ohms on one side and almost zero on the other)? :magnet:

Beats me. Maybe if you split a zip cord and run the halves on either side of the room, you could pick up interference from your mains wiring or a badly shielded power transformer. But then we're quickly leaving the realm of balanced connections anyway.
