Bi-amp with same sort of amp?


Talked to a man today about my loudspeaker project(that never gets ready).He ment that it´s preferable to use the
same type of amps for the subs and the rest of the system.
According to him, using different types of amps, with different slew-rates ("speed" -if you want) often ends up in a mess.
I use Volt 12" woofers, in separate enclosures, and I will run them up to about 65 Hz,only, using a VMPS electronic crossover(only low-pass filtering). I will use a 8" and two 3.5" Accutone ceramic drivers and an Eton ER 4 tweeter per channel.
Having built some speakers in my days, this is my first time
using an electronic crossover for Hi-Fi.(I used the word bi-amp for convenience, in the title).
Any opinions are welcome!

it is generally more difficult to match differing amps for bass & mid/treble. that said, as abstract7 points out, it *can* be done, but ya have to pay close attention to the characteristics of the speakers & the amps.

using an active crossover, w/adjustable wolume for at least one of the amps, makes things a lot easier. my current system uses a pair of larger vmps subs, crossed-over at 60hz, to a pair of meret re monitors. these monitors have an eton carbon-fibre woofer & a focal inwerted-dome tweet. i use a pair of bridged adcom gfa-555's to drive the vmps', & a pair of electrocompaniet aw60ftt's in a wertical-biamped set-up to drive merets. i have *no* problems w/the different amps, because the 60hz crossover point is effected w/a marchand 24db/octave active x-over. besides offering separate bass & treble wolume controls, it also offers a wolume control *at* the x-over point. this makes it easy to match differing amps w/differing slew & gain rates. i highly recommend using an active x-over in general, and for transparency at a reasonable cost, i feel the marchand can't be beat. while i don't have direct experience w/the well-regarded bryston 10b, for example, more than one person told me the marchand is more transparent, at half the price. the marchand is also more flexible, imho...

hope this helps, doug s.
