Can someone help with advice on subwoofer settings please ? Basically I'm just wanting the subwoofer to enhance low frequencies for 2 channel TV/DVD watching and CD's via the DVD (It's an excellent quality CD spinner for once - the Philips DVDR 1000). I use the line level input on the Vibe from the subwoofer out on the Yamaha. I use my Marantz PPM66 KI sig as the main amp connected to the SL6's with short lengths of pricey Kimber 4tc cable. The Celstion's response is variously given as going down to 60 or 70hz (3db). My questions are : 1. Do I need to select "small" speakers on the Yamaha or won't it make any difference ? 2. What level should I set the Vibe to kick in ? 3. Or should I be setting the crossover level on the Yamaha and setting the crossover dial on the Vibe to maximum frequency ? 4. Would I do better buying some more speaker cable to connect the amp to the sub to the speakers and avoiding the line level input altogether ? Thanks (third attempt at editing this to make sense - sorry).
