Biamp question

Do you need to pay attention to the crossover points or are they going to be pretty standard?

You will have to figure out where the crossover points are for your speaker. Looks like 2.8 K is where your speaker splits but double check that.  

OP you can bi-amp using the internal crossover within the speakers, just remove the jumpers between the LF and HF terminals. That’s not how I would do it, but it is possible. For me, I would follow russ69’s advice. What russ described is not hard at all and would yield the best results. You can use any number of crossovers including DSP’s but I prefer analog crossovers. I’m not positive what crossover russ is using, but if I recall it’s a DBX223. Looks like the crossover frequency in the speakers you mentioned is 2.8kHz., but you should check your owner’s manual. Literally there are 100’s of choices for an active crossover. I’ve been multi-amping for 42 years using analog active crossovers and I will never go back to using a single amp again. Enjoy!

If I’m not mistaken don’t you need to make sure that both apps have the same amount of gain? Whenever I have by amped I’ve always used the same amps or apps from the same manufacture. That way they generally have the same amount of gain as you turn the knob

My experience with using very different amps (LF = PP KT88, Class D GaN, Class AB SS and HF 2A3 SET) that within my listening range (75 db - 100 db) they all match within a db or so. So the "gotta have the same amps" thing is something I don’t believe in, but you must have a way to adjust either the HF or LF output so the two match.

What I do is measure the outputs to make sure the high and low outputs track:

I use a RS meter about 1 foot in front of the HF driver with the LF amps turned off and adjust the main volume so the meter reads 85 db when playing a 2K Hz tone.

Then I put the meter about 1 foot in front of the LF driver with the HF amps turned off and adjust the output of the LF amps so the meter reads 85 db when playing a 500 Hz tone. Now the outputs are matched at 85 db.

Then I adjust only the main volume and play 75 db, 80 db, 90 db (already baselined at 85 so no need to do that again), 95 db, 100db measuring LF at 500 Hz and HF at 2K Hz and see how close they track.
