Thanks to a recent hardware upgrade, I now have the ability to overlap "shared" freq's betweenst my Carvin 1503's (52 hz - 18 khz) and Yorkville subs (60 - 300 hz). As suggested by a local sound pro, the settings are currently:
Mains: 75 - Inf
Subs: 50 - 90
Can't recall the LR and BW slopes. Sounds good so far and there's nothing distinguishable coming thru the subs. Can you think of any considerations which I may have overlooked? I am aware of the 60 and 90 hz bumps which sometimes occur and will pay closer attention at this evening's gig.

That's about all you can do. I don't see what good could come out of it, though. Those freqs are all omnidirectional anyway, and it really doesn't do them any better to come out of the mains unless you have a weak sub. OTOH, you mix sound with your ears, so if it works for you, then rock. Won't hurt to give it a shot or two.

you'll get more headroom out of the tops by not asking them to waste energy trying to push out 75Hz. also, having multiple speakers some distance apart producing the same frequency means phase cancellation issues come into play.
i would stick with a normal crossover point, say 90-100Hz.

I'm not sure what you are trying to accomplish. Do you have under-powered subs that you are trying to help out or something?

In some sense, yes. They are budget Yorkville 18"s and do a decent job but the Carvin 1503 mains have comparable low-end ratings (Yorkies - 60 hz, Carvins - 52 hz).

Depends of the slope.
Say it's a 6db/octave slope , it's oK like that
If you put a more drastic slope , you could set both the frequency closer to 90-100Hz and closer together.
( 24db/Oct BW - Low 0-90hz / tops 100-20Khz )

In my experience, the more bottom you can drop out of the tops, the more the mix will clean up for mid-range things like guitar and vocals. But like Jimmy said, mix with your ears. If it sounds good leave it, if it sounds bad, try something else.

Certainly makes sense and ties in with Walter's observations. Should free-up some headroom on the mains.
