Sounds like a good idea. That said, bi-amping or tri-amping speakers should not be undertaken without first asking the manufacturer’s advice.

When I horizontally bi-amped my speakers with an analog active crossover design by the same manufacturer (of the speakers) it brought my speakers two notches above the passive crossover in sound quality. 😎

@ditusa - thanks for the article. My idea is using the SIT-3 from 0-500, a 45 amp from 500 to 7000 and my heavily modified Bottlehead 2a3 from 7000+.

Active Crossover Conundrum!

Active Vs. Passive Crossovers

@russ69- I assume you could use a 2 way by using a passive XO between midrange and tweeter and have the ability to tweak the Bass/Midrange intersect. 

You can do that of course but a full active crossover might be more efficient. 

@kota1- Thank you for your response, If I go down this route, some computer software, measurement tools will be a must.

@russ69- I assume you could use a 2 way by using a passive XO between midrange and tweeter and have the ability to tweak the Bass/Midrange intersect. I appreciate the affordable XO option.

I found this article interesting written by Dr. Harvey Rosenberg interesting.

Yeah don’t do this 

No, you cannot use a two-way crossover on a 3-way system. If you are going to tri-amp, you’ll need a crossover where you can control the crossover point and the gain for each speaker. The DBX234xs is an affordable choice.

Hey OP,

Replacing a factory passive XO with active is not usually that simple.  There is often a variety of EQ and phase optimizations that take place in the passive XO which must be accounted for in the active to be an equivalent match.

I think I see a lot of need to be creative and experimental in your question, but you are also getting much more complicated.  More cables, more amps, more, more.. :)

My major suggestion is keep things inexpensive, so you can try different combinations without breaking the bank.  Consider a miniDSP with measurement microphones, and visit the DIYaudio forum

@coachpoconnor , I would upgrade your room treatments or try the miniDSP with dirac room correction. I think you will find it easier and just as rewarding. My current speakers use active crossovers and yes, I love them, but the room treatments and room correction took them to a level that the crossover would never do. I find active crossovers provide me the most benefit when listening to bass heavy content near reference levels. At lower volumes I don’t know it would be worth the effort for you.
