    I just picked up the 3803 thanks to this forum (thank you) and I have Klipsch Reference Series III v2 mains and surrounds w/ a pair of SVS 20-39CS+'s. Should I set the 3803 crossover to 80Hz or 60Hz?

    John,

    You didn’t provide any info on your speakers, and I can’t find them on Klipsch’s web site. And I can’t tell from the pictures at your link if where the subs are in relation to the front speakers. It would also be helpful to know what the slope of the receiver’s crossover is (or whatever crossover you’re using).

    Very nice pics, by the way. [​IMG]

    My vote would be for 80hz as the Ref 3's F3 point is about 42 hz if I remember correctly....This will let the Klipsch concentrate on getting the mid-bass and mids correct and not have to worry about the bass...[​IMG]

    I have mine at 60hz with Studio 20s. I am much happier than with 80. I have much better bass response in my room now, and my front soundstage has more depth. My sub is also playing cleaner and louder since it doesn't have as much work to do.

    It works great in my room. But it is up to you to decide which is for you. Try both. I think the RF3s will be able to handle the added bass.

    My SVS subs are about 12 ft to the right of the right front speaker and 20ft from the listening position. If I set the internal crossover of the Denon 3803 to 60Hz will the center and surrounds also be filtering 60Hz and above? Looking at the specs of all the speakers it looks like 60Hz could be a viable option.

    *Wayne, thanks for the compliment on the pictures. [​IMG]
