I have a question about crossover frequency settings. I've searched this thread and saw some suggestions on the promonitor 600s and 800s but not much on the 1000s. So how low can I set the 1000s? Is 80hz too low? What are the consequences of setting it too low? Is it basically you are sending too much low frequency signals to your speakers with relatively small drivers so they will distort at higher volumes?
How about the LFE? I have the sub connected through the single LFE RCA cable. Crossover on the actual sub is set to max so that way I'll control the crossover on the receiver. Right now I have the LFE set to 120hz. So now there is a 40hz overlap between my front/center/surround speakers set at 80 and my sub set at 120. Is that something to be avoided? Should they match in freq (say everything set at 100hz)? I'm really quite confused.
You can call or email Def Tech and ask them, but in my experience every time I talked to someone else at Def Tech I got a different answer for my 800's, from 80Hz to 120Hz, so I'm not sure there is only 1 answer or if there is, they don't know it either - which is surprising.
The LFE setting has nothing to do with the crossover of the speakers as far as I understand it. That's just specifically for the LFE channel information (e.g. Dolby Digital 5.1), it allows you to cut off upper frequencies if your sub for example cannot deal with something above say 120Hz. But I understand usually there's no information above 80Hz on the LFE channel anyway and even setting it at 80Hz would not hurt anything.
Btw, if you have your speakers crossed at 100Hz and set LFE at 80Hz that will NOT mean you have a gap between 80-100Hz for the reason above. The LFE setting will only clip the info that's specifically on the LFE channel (DD5.1, DTS, etc. but not Stereo for example).
Here's a review on the 800's and they guy crossed them at 75-80Hz which I think is too low for the 800's, but crossing your 1000's at 80Hz may work very well:http://www.soundandvisionmag.com/spe...er-system.html
