I am in the process of installing new 7.1 HT system. Yamaha 1500 (120wpc) will likely be driving BagEnd MM8H mains with in-ceiling surrounds. I have to run the wires to the surrounds behind sheetrock up a wall and across the ceiling. Total run is about 45-50'. In-ceiling speakers are not yet chosen but looking at the mid-range SpeakerCraft AIM8s. (Need aimable speakers so I will entertain alternative suggestions). I will be installing surrounds and rear surrounds so I have four runs to install. I will also be putting in Presence speakers but those are only 15' runs. All runs will terminate in a wall plate with banana connections.
After reading enough forums here & elsewhere I have decided to run four conductor 14ga and pair the leads to create an effective 11ga cross section and pick up the lower resistance and twisted construction interference prevention benefits. I will have to deal with the placement of in-ceiling halogen fixtures and will likely cross a couple of 110v lines at right angles (I know enough not to run parallel). Note that I will also have the transformers of the halogens fixtures to deal with so let me know if that is a problem other than standared power line issues.
Question is choice of in-wall cable. While I don't have to watch every penny I don't want to spend more than I have to (Speakercrafts are not cheap). I have made CL3 a requirement though will accept CL2 (some have FT4 rating as well). My list of in-wall contenders is down to:
Ultralink CL414 250'@$160 (64¢/ft)
www.av-oulet.com
Direct Connect 14/4 250'@113 (45¢/ft) av-outlet.com
Impact Acoustics 14/4 250'@$80 (32¢/ft) - this is without the 20% discount
PartsExpress 250'@$85 (34¢/ft) partsexpress.com
Monster 14/4 250'@$263 ($1.05/ft) for price comparison purposes only
Any thoughts based on personal experience will be greatly appreciated. My inclination is the Impact Acoustics though I really like the UltraLink product. I will likely use the Ultralink to build cables for the mains irrespective of the in-wall selection.
