Thassa good idea - I'll do some troffing.


At the moment, I'm thinking of 100W low bass, and 50W each for
bass/mid and treble. Won't my T27s freak out if there's a 50W amp
dedicated to them?

You might fry them.

How about if I was disciplined with the Cyrus volume control?


The power split depends on the frequency ranges split off for each
driver, and how much energy is in each band, for different kinds of
music.

You can measure the voltage across the driver voice coils while the
system is in use. A 'scope or better yet a digital recorder are good
tools for this. You want to look at peak levels because that is the
critical case for undistorted operation.

Righto.


Here's a low cost 3-way active crossover with a good reputation and
lots of flexibility:

"Behringer DCX2496 Ultra-Drive Pro Digital Crossover System"

Looks like a nice bit of kit, but a bit pricey for my budget, I'm afraid.
I'm considering something home-brew.
