I'm still working with my new HT setup: Revel F30 (Front) Revel C30 (Center) Revel S30 (Rear left, right & center) SVS Ultra (sub) B&K Ref30 (Peamp/Processor) B&K 7270 (Amp) Crown K1 (Sub Amp) I'm trying to set the best crossover point between the Revel's and my sub. I have it set at the standard 80Hz now. On the Ref 30 I have the front speakers set as large and the center and surrounds as small. It sounds fine but I want to make sure its at the best setting. Some help would be appreciated.
