In the manual setup of my Yamaha HTR-5760, for front speakers there is the choice of SML or LRG. When SML is chosen, the lower bass frequencies assigned to the front L/R channels are passed along to the subwoofer; when LRG is chosen, the lower bass frequencies assigned to the L/R channels are passed along to the front speakers themselves, as intended. I have the JBL E80s for fronts and have found I almost prefer the sound better when I choose LRG because the lower bass frequencies are evenly spread along the front soundstage, however, the subwoofer isn't pumping out as much bass. When I choose SML, the highs and midranges are clearer and the subwoofer is pumping out more bass, but it doesn't sound as "full" or "ambient". For reference, I have the JBL E150 for the subwoofer, but am thinking of upgrading to the JBL E250, however, have read it's more "boomy" (I know, this specific topic would be better suited to the speakers forum). I guess my question is whether or not the JBL E80s would be considered LRG speakers and will I hurt them over time pumping the lower frequencies for the front channels through them, or should I be choosing SML on the receiver to save my front towers from the low frequencies? Or, before my 30 days are up, should I upgrade for the JBL E90s? Or should I not worry about the E80s at all and let me ears tell me what to use because it won't hurt my speakers one way or the other. I also realize this a combo receiver/speaker question, but since the receiver itself is asking the SML or LRG option, I figured this could best be answered in this forum. Thanks again to HTF. This place rocks.
