    I am looking at the Denon 3803 which has 40,60,80,100,120 and the Marantz 7400 which only has 80,100,120. I have B&W 603 for fronts, lcr600 for center, and 601s as rears. Sub = maybe 600 or 675. Would I need the lower crossover settings the Denon provides?

    If you plan on using a sub, then set the crossover at 80 so you can let the sub handle all lower frequencies. THX recommend setting the crossover at 80hz for hometheater applications. If you don't have a sub then the Denon would definately be a better choice as far as bass management goes. My crossover is set at 80hz, my speakers are B&W cdm7nt similar in size to your 603 and a 650 sub.

    I asked the same question a few weeks ago and the concensus was 80Hz. [​IMG]

    My mains are set at 60hz and my center and surrounds are at 80hz.

    This will not work for the receivers in question. Both the Denon 3803 and Marantz 7400 use a single, global crossover for all "small" speakers and the subwoofer.

    Sorry, I had thought that the Outlaw 950 had and outdated feature set by today's standards. [​IMG] [​IMG]

    The best recommendation I have come across, is to set the crossover at 1/2 to 1 full octave above the -3 dB point for your speakers. Guarentees that the slope the crossover imposes on the signal is not interferred with by the natural roll off of the speaker. That is a lot tougher for a global setting, in that you're almost guarenteed to get a dip in the response for the surrounds and rears which rarely have low enough extension. fwiw! [​IMG]

    If your receiver/pre allows and you have full range fronts, I would encourage a lower crossover point of 60 hz. Try it on your system and compare to 80 hz, you will get a fuller, better integrated soundfield. Note that this does not apply to sub/sat combos...

    IMHO, you need to investigate the various options with a sound meter, plotting the frequency response curve for variations from the predicted choice based on speaker capabilities. With my current setup 80Hz would look to be the best choice. But, due to room effects, 100Hz gave me a flatter curve.

    YMMV
