    So, I've got a new Denon (well, refurbished by Denon[​IMG]) AVR-1705 receiver on the way, and I have a few questions about crossover since my old receiver was a stripped-down sony HITB which had no crossover options.

    Basically, I've gotten the gist that setting all main speakers to "small" and having your sub handle as much bass as possible is the way to go. Why is that? Does it free up the amps that would be wasted on redundant bass for the main speakers? Would I get better sound range, separation, and reproduction from my main speakers (JBL E80 for L/R and JBL EC35 for center) if I sent as much bass as possible to the sub (an SVS PB10)?

    Once again, THANK YOU for any help[​IMG]

    yes send the bass to the sub , better dynamics , easier on the rec.,and often better clarity(I recommend about 100 hz), this will keep the bass from being localized in other words it won't sound like it is coming from the sub, of course location of the subwoofer will have an effect on this....hope this helps.

    Sending all deep bass to the sub is a good idea for many reasons. Your point about the receiver's amps is valid and thats just one. More important than that is that the woofers in the main/center/surrounds will make much cleaner 100-500 Hz sound when the cones are not wildly swinging at 40-50 Hz also. Further, deep bass from multiple locations can aggrivate cancillations that WEAKEN the impact of the deep bass at some frequencies. Since your ears cannot locate the source of deep bass anyway, it all may was well be produced by the specialist that is optimized for that job- your SVS.

    There is a situation where sending all bass to the sub can be problematic- when the sub happens to be located where it interacts poorly with the room. Finding the better locations is trial and error.

    Hmm you will have to see what particular bass management is offered by that AVR....

    In this case, it would be really awesome to be able to set the crossover for your E80's to like 60hz, and yet keep your center at 80hz or even 100hz....


    Move the crossover up in frequency, and place more demand on your sub and free up some demand on your amps and main speakers, move the crossover down and you put less demand on your sub and put more on your amps and main speakers.


    Experiment a lot with it, before deciding which is truly best.
