I'm new here and at the moment i dont have any ML gear except the grotto sub.Maybe in the future i will be able to get a full ML setup.I presently have a rotel rsx1056 with B&W 603s3's(would like ML).My question is if anyone could advise me concerning the grotto.Right now it's connected via the lfe input to the reciever.I know when connected this way the crossover is disabled.I can set the crossover for the grotto via my reciever as well as other settings for music,dolby dig. stereo,2ch etc..I have it presently at 60hz i believe and my main speakers which are also done via the rotel are also set at 60hz and to small.My question is should i set them differently,all these controls on the grotto though not confusing i still dont get it/fully understand.I'm trying to set this the way it should be.Any opinions or recommendations would be greatly appreciated.Man,sorry for the long post.
