Where to set crossover

[joelincoln]

Newbie here.

Love this forum... lot's of solid info and friendly folks.

I recently bought a Yamaha RXV2400 receiver and Paradigm PW-2200 sub (BASSO PROFUNDO !)

Both the receiver and the sub allow crossover adjustment. For now, I'm using 80 Hz.

My question is, if I set the reciever at 80 Hz crossover, do I also set the sub or do I leave the sub crossover to max (250 Hz I think)??? Or does this matter?

BTW, the rest of my system is...
Paradigm Studio 60 v3, CC470 center, ADP rears
Yamaha CD changer
El-cheapo DVD player (for now)
Monster OMC speaker cable and Monster interconnects (for the most part)

You want to set the sub cross over as high as it will go, to get it out of the way so to speak. If you set the receiver to 80Hz and the sub to 60Hz then you will have a hole (missing frequencies) between 80Hz and 60Hz (The receiver will send 80Hz and below, but the sub will only 'accept' 60Hz and below). You won't totally lose those frequencies of course because the cross overs use a slope, not a brick wall, but it's to be avoided anyway. The slope simply indicates the rate at which it "rolls off"; ie attenuates, those frequencies. For example, a 4th order (24dB/octave) low pass crossover would roll off the highs at a rate of 24dB/octave; thus with a setting of 80Hz, the frequency 1 octave above (160Hz) would be attenuated by 24dB.


You may have other options as well:
Some subs have an input specifically designated 'LFE' or the like that bypasses the internal cross over and if you use that, the setting on the sub is ignored. Others have a switch you can set to accomplish the same thing, sometimes labeled 'bypass' or 'in/out'. If you have that option, use it so you don't have to be concerned about the position of the sub's crossover dial.

Thanks for the info, UNREGISTERED.

What you suggest is what I did in the first place. Now I feel better that I did the right thing.

hey Joelincoln, I was curious to know when you did the YPAO for your speakers did you turn the sub's crossover to max or min? I have the same receiver and I think I set the powered sub's crossover to min and the volume to a little below half-point when doing the YPAO. I wonder if that was correct or not. Lemme know what you did. Thanks!

crossover setting

What do you set the crossover at if your DVD player and your Receiver both have bass management. Are they both set at the same number 80 or so and the sub set all the way up? I have the Denon 3805 and the Denon 2815 multi disc DVD player.

I'm no expert, which is why I posted the question in the first place, but it seems like, given the choice, you should rely on the electronics in your receiver/dvd to manage the crossover. So you should set the sub's control to max (highest freq) which is what I did when I used the YPAO.

Keep in mind that the current YPAO system in the 2400 does not equalize below 60 Hz anyway.

The DVD player's bass management only takes place on the multi-channel outputs. So if you are not using those (for SACD or DVD-Audio) then it doesn't matter.

If you are using those, then set it identically to your receiver, unless you are using a separate set of speakers for some reason or prefer your bass management set up differently for music than home theater.

Sub still gets bypassed, or set to the highest setting (unless directed otherwise by the manufacturer).

Thanks for the info Hawke. You've helped me greatly. Now if we could just get that review of the 3805.
