Amazing that those two oft-berated "junk" brands are making clean usable gear. I was expecting to get jumped on.

Perceptionchanges, was that the balanced or unbalanced AC23? If it's the balanced version, would you consider selling it? I'd like to have a pair.

SO it is possible you might value being able to "recall" different setips for different listening situations. Indoor versus patio speakers for example. And on digital, the frequencies will probably be right on, versus a small analog knob with numbers around it.
I'm pretty sure my home system here is going to be a "set it and forget it" type. There may be a little bit of experimenting, but not much. I already decided the crossover frequency is going to be around 500 Hz. Some of the other features these units have may be useful for me, like delay for example. Once I've figured out what works best, I don't intend to change it unless something unforeseen happens.

I've looked at the Marchland products and I appreciate the man is very talented and dedicated but I'm not into DIY on this item and his finished stuff is high quality with a corresponding price.

I'm not sure how these typical professional type crossovers are used in the field. Do professionals change the settings fairly often, depending on the venue or what ever? I'm still learning here. Thanks everyone for their input so far.

It's extremely rare to change the xover points for a system venue to venue. Delay time of the elements of the system change almost every move, as well as eq. How much depends on the venue. Some manufactures like Meyer and L' acoustics even lock parameters like box tuning, driver alignment and so the system as a whole can be tweaked, but not individual pass bands.

The MiniDSP kits are definitely worth looking at, the price/performance is fantastic and they really are easy to use, + with new software modules and updates being released/supported its an easy upgrade path to more units later.

Yeah, that's an option as well. Does the MiniDSP have as good specs as something like a dbx? (greater than 100dB S/N, less than 0.01% THD) What kind of slopes do they offer (24 dB/octave, 18, etc)? What about delays? I need/want balanced XLR connectors for this and the MiniDSP I looked at only had RCA connectors.

Which brings me to digital vs. analog crossovers. Do the digital ones add strange "coloration" to the sound as compared to a good analog one? Are the analog ones typically worse or better in your experience than the digital, or is it just about various features like repeatability?

OK, I do see that MiniDSP has a balanced module for $145, but I'd still need a box for the XLR's. Also, I'm leery of all this D/A conversion. I have a DAC that I think is very nice:
Little Dot Amplifiers • View topic - Little Dot DAC_I Digital to Analog Converter
So, I'd like to use it. It's almost a digital preamp because it has 4 selectable digital inputs. It just needs a volume control. Anyway, converting to analog and then back again to digital in a digital crossover isn't logical to me, but I know many do it with great success. I think I've just talked myself into an analog crossover, though of course I'm open to digital ones also, just scratching my head about it.

I found the Behringer digital introduced less noise and coloration that a similarily price analog crossover and more than likely the DAC is close to as good as a little dot.

As far as picking a crossover frequency and just sticking with it, why? At least start with the Behringer, tweak in real time, find the ideal settings, then if you want to upgrade you won't be taking risks on buying cards that cost more than you would lose by buying a brand new DCX2496 and then selling it for a loss.

Those are good points, thanks. I see that this Behringer also can accept digital signals directly via one of the XLR connectors. My CD transport (also the Little Dot) has S/PDIF output via an RCA or BNC connector. How do I convert this to the AES/EBU signal that the Behringer requires? I'm sorry I'm not more familiar with digital standards.

The features of the Behringer are mind boggling to me.

What would I recommend? Well, I do own the DCX2496, but I don't use it at home. Until I went over to the dark side and bought an AV receiver, I used a DIY 4th order crossover. There's the Marchand boards. electronic crossover, PLLXO, passive crossover, active crossover, custom amplifier Maybe there's a kit from Elektor. Someone must sell a generic/cookbook active crossover board. But it wouldn't be hard to build on prototype boards, like those ones that Radio Shack sold that used the same layout as a solderless breadboard.

Maybe buy a used variable (semi)pro crossover and convert it to fixed frequency (and upgrade power supply, op-amps, caps).

My favorite is BSS. I have 2 Bss FDS366 for my pro use and one 344 for aux dj setup........
But I'm afraid that BSS units are very expensive..
I think that digital active crossover is one and only right approach if you want to have full control over your system.....but just my opinion....
So maybe this can help you.....I never tried those products but looks very promising.....
Regards, Taj
