Hey guys I am thinking about bi amping my system and using an active xover. Anyone here have any expirence with active xovers, or advice on which xovers to stay away from???

My speakers are Klipsch Khorns with upgraded drivers and passive xovers. I am using a 2" driver BMS 4592 mid, 2" tractrix horn from Volti Audio xovers are ALK Universal's. With an upgraded tweeter as well.The ones I have used (numerous, including a number of custom active and passive units) would be dated now so I can't help with current stuff. What speakers do you have, and what do you know about their crossovers? What's your technical knowledge base? Realistically, and IMO, trying to dial in an active crossover without a decent amount of technical knowledge and some measurement equipment can be teedious, painful and unfulfilling.
That said, the program I currently use for measurements (RPlusD) has some great optional modules to find settings for various digital filter systems and includes a lot of algorithms and features to help build crossover networks. If you're willing to invest the time in the tools, the result coiuld be very impressive.
My system was bi-amped last time I had it running and it made a huge difference in sound (yes, a good difference!) Now, however, I do not feel the need to repeat with my current electronics and room. I find the benefit to be rather system-specific.
HTH, YMMV - Don
Amir, for the time being I just want to get my feet wet, I am going to borrow my friends SS amp for the LF and buy a xover yet to be determined!!What's your budget?
Here are the specs of my current xovers!!!K-horns have a fairly simple crossover, I think... Been ages since I heard (or tore apart) a pair. Seems like it was 2nd-order LPF to the bass, but might be 3rd-order HPF to the upper horn. If you can, look up specs on them (or the drivers) or test results and see if you can tell the crossover order, then you may be able to get away with a pretty simple design.
You might check out Sweetwater Sound (www.sweetwater.com) and similar pro outlets for crossovers. Chances are you can get a pretty decent one for not a lot of money that has very flexible control, like one of the DSP-based units. There are also cheap analog models, though the very cheapest tend to be noisy.

Here are the specs of my current xovers!!!
Crossover rates are 6 dB / Octave on the woofer. 12 dB / Octave on the squawker and 18 dB / octave on the tweeter.
Crossover frequency is 400 Hz from woofer to squawker and 6000 Hz from squawker to tweeter.
The network is a true multiplexer providing constant load impedance to the amplifier. The amplifier sees the speaker drivers, not the network! With the woofer and tweeter outputs terminated in 8 Ohms and the squawker output terminated by 13 Ohms, the input polar impedance to the network is approximately 8 Ohms +-1 Ohm at +-10 degrees from 20 Hz to 20 KHz.
