logic cs1290b 6th order EQ help.

So these bins need a 9db boost at xover?

I found these numbers from an old post:

STEREO 2 WAY
X OVER LOW OUT:
HIGH PASS 40Hz LR12
LOW PASS 150 Hz LR24
GAIN 0 dB

EQ:
LOW OUT PEQ 1
SHAPE BELL
FREQUENCY 40Hz
GAIN 9dB
Q 0.94


They are for the original system obviously..




My question is this: Will these cabs work with that setting in any rig? Or are there other details to address to make them work well. I believe the answer to be yes but I'm not confident. That LR12 looks a bit shallow for safety that low down the frequency range? Any advice much appreciated.

do they present any unusual issues in use? I also know they were designed to get the same amplifier signal the subs got. Is that a viable option once removed from the complete LOGIC system? Not the same amp maybe although that would be useful) but the same dsp signal? A pair of these with the subs running up to 150 as well? All on the same xover and eq?
That's feels a bit high to cross out the 18'' subs, I'd be more likely to match both subs and these at the low end and then cross out the subs at 80.

Any advice or thought on this crossover set up with these bins would be much appreciated.

Cheers

Yeah no way I'd run a sub that high either, I agree with Elliot use whatever crossover frequency that blends well with your system.

As for the boost that is a common thing with many types of subs.. at tuning frequency driver excursion is at a minimum so it will take more input there, whether that helps overall depends upon a lot of things. Bandpass designs are often pretty terrible 1 note wonders and that boost can broaden the response and make it more musical. It will also help the boxes dig lower but you have to be careful because below tuning the driver is unloaded and easily damaged, so yeah a steeper high pass filter wouldn't be a bad idea... especially if you have lots of power behind the driver.
This is one of those situations where I'd want to do some testing, measure the boxes and apply enough EQ to flatten response but no more, set a high pass that doesn't intrude too much.. a 24dB butterworth filter naturally adds a little boost just above cutoff, add limiting and call it good.
