Noticeably better to let your Receiver control crossover? in Home Theater Posted October 14, 2005 My receiver does have large/small menu options for mains and does let me specify whether I have a subwoofer. You suggest that if I can tell my receiver I have no subwoofer, then I should choose that (presumably because then I'll get all frequencies sent to the sub and I can manually set the sub to pick the optimal crossover frequency?) (and I'll get the use of volume control via the receiver). Should it matter whether I choose large or small for my mains (currently I selected small mains and "yes" to subwoofer)? The other alternative presumably would be to tell my receiver that "yes" I have a sub. You suggest that my receiver has no crossover. But if that is the case, why would it have a menu selection to specify whether I have a sub or not (independent of whether pre-outs exist, which you explain above). Is it possible my receiver has a fixed crossover frequency? What purpose would the menu selection serve if not to have to receiver manage the crossover? If this is also is an option, is it likely I would get a better result relying on the receiver to manage the crossover? I appreciate all your assistance. Forgive me if I'm misinterpreted what you're trying to explain. I'm also tempted to email Klipsch to have them clarify how the 2800's crossover works.
