Taken from Datasheet "Hooking up SpeakerLink" June 2008
No cables are supplied with the product as you can use standard Ethernet cabling as long as it is STP (Shielded Twisted Pair) CAT 5 or 6 cable. You may need to meet additional standards when installing cable in-wall, but as far as SpeakerLink is concerned, CAT 5/6 STP is all there is to it.
We have been researching and auditioning a variety of CAT5 cables and have developed a flat cable that we will introducing in the near future as a Meridian-branded CAT5 interconnect for critical audio applications. We have selected this cable for its extremely high technical specifications and sound quality.
