I've searched exstensively, but i've yet to come up with any solid options. Here's the dilemmia. Rockford Fosgate 8250 balanced to a pair of IDQ-31 EQ's, to a crossover (?), through to. Tru Tech T4.65 to CD-2 horns and 4 or 5 inch mids, Tru Tech t2.100 to IDQ-8 midbass most likely, and a pair of IDMax 12's on the bottom run off some sort of amp, undecided at this point. The question is, what XO could fit into this situation? any and all suggestions are appreciated.

Well, my top choice has always been the Behringer dcx2496. The price is absurdly low at $250 shipped now. It will do xover, time alignment, phase adjustment, eq, and more ... also has a nifty computer hookup so you can control the thing with a laptop, or a nice jog dial if you have to use manual controls.

I'm just curious though, aren't you going to have a big sensitivity mismatch between the horns and 4-5" mids?

And, if you can't tell I'm all in favor of ditching the analog eq's for a digital all in one solution :)

It does need a 12 conversion, which you can get here:

It's really the most comprehensive piece I've ever used. The best in terms of flexibility and power. Outputs are 9Vrms so that's pretty nice too.

Other than that I think whatever from Audiocontrol would work, or you could even use the Tru analog xover. You just wouldn't have the flexibility of adjustable slopes, accuracy, and points like a digital unit.

my thoughts exactly on tru, or other analog pieces. i've heard the 4xs from audiocontrol has noise issues, so i don't even want to go there. it seems that a lot of competitors like to use the PXA-700 or 701 from alpine. would that be something worth looking into? my initial look at it gives me favorable impressions.

That (Alpine) would definitely be worthwhile as well, although the cost would be quite a bit higher for less performance than the Behringer. The remote face control and smaller size/convenience is a big plus though.

I can't really vouch for the behringer gear, but i can the h-700.. I am using it with cd-2 mylar's, morel mids and max subs so i am kinda familiar with what your doing...I have to say though, there is no way possible that a 4 or 5 will keep up with the horns unless you can 10x the power....10w to horn and 100w to mid..seriously....although I am doing a 2 way front and not 3, and the morel's are somewhat inefficient, unless you do a pro mid like phl, b&c or the sorts, audax has a nice one i hear, you will have a hard time with running 30+ watts to the horns. I am still debating on running a 3 way front myself, but if you are going 3 way, I would do a 8-6-horn...keep your 8's at 150-200 and lower and mids from 150-200 on low side and and 1k-1.4k if mini's or 600ish to 1k if full...

another thing you have to look in to, not too many processors out there that will do a true 4 way setup...dual bandpass abilities I mean...if you do find that, by the time you get everything that the h-700 can do, your in the same boat $ wise...I don't hear these noise issues that people are talking about but I am running ainet from a 9815 too and not running rca's to the brain like some are with a different brand source...if you use another brand head, I would find one with a digital out and use the controller for volume....your head will be dead (transport only) if you don't use alpine..

good luck in your quest though man...once you go the horn route, it opens a whole new can of worms imo personally....staging is out of this world

the behr site doesnt have much useful info on the eq section of the dcx2496... i had no idea it even had any, always thought u had to pair it with the deq2496 which is what i was considering for a while and still might do. wanna tell us more about that?

If i had it all to do over again I would go with the alpine h-700 and a compatible deck. Why fuss with extra peices, I would do the deck and processor and be done with it.

I run the p9 combo now and don't even think about anything else....but I also have a convenient way around the 250hz lpf for the midbass, which some people may not have.

A friend of mine uses that behringer unit and likes it alot.

i'm also considering the p9 combo. i've heard about this freq problem on the midbass bandpass....can you elaborate for me, and explain what the problem is and how you fixed it?

Bump, I'd like to know more info on the EQ as well.

The behringer works more or less like a computer. It has a set amount of "processing power" that gets used up as you do things. So nothing is set in stone, you can have 100 bands of eq on 1 channel, 10 on each channel, 5 on 1 channel, 2 on another anyway you like until the processing power is all gone. Likewise, you could also do 72db slopes on your crossover, but it will use up more power. You can set crossovers, time alignment, level adjustment, equalization independently over each input (3 of them) and each output (6 of them). You can also reroute or tie together any of the input/outputs as you like.... so you can group output 1 and 2 together so that any change you make on one goes to the other.

The eq on the behringer is also selectable into 3 types. Bandpass, lowpass, and highpass. Highpass and lowpass are much like your typical crossover, and "bandpass" is your typical parametric eq. You select your center frequency(anywhere from 20-20khz) and a q(1-10), and boost or cut +/- 15db. It's extremely flexible and you can shape any kind of response you want... unlike your standard 31 band eq where the 'q' is fixed as well as the center frequency.

For example here is my right mid/bass equalization which uses 5 bands of eq:



Try getting that kind of funky eq response from a regular eq...

When NpDang showed me how to use it, it seemed fairly (really) easy.. Simply push a numbered botton (one of each channel) and turn the knob to change the frequency (frequency steps were in small increments). im sure changing the slopes wouldnt be much harder then that..

you can also tune it with a PC or laptop via a serial connection. you can download the software here: http://www.behringer.com/DCX2496/DCX2496_remote_1_16a.zip you can play around with it. seems like its pretty easy to use.

Both the front panel and the software are easy and intuitive to use. I was up and fully running without ever looking at the manual... and in fact I'd say the front panel controls are the easiest, most efficient controls I've ever used in a digital processor. The Alto drive 30, pioneer p9, alpine h701 completely suck compared to it in terms of ease of use.... mainly in the fact that you have to scroll through so many menus to do anything whereas the Behringer is pretty much push one button and you're there.

I'm also using the analog inputs with a Pioneer 860mp source... since there's no digital volume control on the unit or remote control it would just suck to use the digital input.

But that would require subjecting myself to a PC....just a couple months ago I cleansed my company of them entirely, so it's only well-designed computers for me!

Cool that the on-unit adjustments work pretty well, though.

How many bands of EQ does the behringer unit have for ea. input / output? I could not find this in the manual, in which I downloaded the software to play with, and it looks like ea input/output has up to 9 bands?

Thanks, Dave
