I recently brought a JBL ATX 100S active sub. Not sure is anyone experienced with this sub before. I need advice for sub connection from my marantz sr 4200. At the back of the sub, there is an L & R line in and LFE in. Crossover range from 50-150Hz. My question is which connection should I go for 1) Receiver sub out to subs L & R line in (with Y Splitter ) 2) Receiver sub out to subs LFE in My current sub setup is through speaker level connection with speakers set to LARGE at the receiver and subs crossover to the max (150Hz). I love strong bass response when watching DVD. My understanding is speakers connection should only be consider at last choice. Thanks.
