How to Bi-amp and maybe Tri-amp
Can anyone provide me with basic guidance on how to bi-amp or tri-amp a set of speakers? I made some DIY cabinets that have E145-8 for the low end 2440 drivers for mid range and 075 tweeters. I am currently using the LX5 and N7000 for my crossovers.
I would like to purchase a 2 or 3 way electronic crossover, and I guess my basic questions are:
If I Bi-amp will I need 2 amplifiers? My guess is the question answers itself. Yes
If I do a two way crossover with a three way system, would I still need the passive crossover for the mid and highs?
Is there any schematics that I could refer to?
Does all the power go into the crossover and get divided and distributed from there to the different speakers?
Does it matter if the high frequency amp is Class A and the low frequency power is Class A/B?
Years ago I heard a bi-amp'd pair of 4350's and it was quite impressive but I never bothered to look at how it was wired up.
I hope these are not really dumb questions
Thanks in advance.

That's what I did with my L-300s, and they sounded much better this way than with the stock set-up. I used a low end (as in cheap) dbx 2 way crossover and ran the LF through a solid state amp directly to the woofers. Used a tube amp for the mids and HF, into the internal L-300 passive network.
It really opened things up on the top, and man that s/s amp ruled those 136 woofs with an iron fist!!!
Good luck!
