Tri-amp 3 way speakers, still worth if using a multi-channel amp? (HiFI Stereo)


Hello to all,

Recently I’m thinking about tri-amp the 3 way loudspeakers that I’m planning to build, I know that the optimum way is with separated amps for each driver, but due the high costs of acquire 3 amps, I’m thinking about an multi channel amp.

Appreciate very much the thoughts from more experienced people about this subject, do you think that with a multi channel amp, and a very nice crossover, the system still will provide the great advantages of an active multi-amplified system?

Will put here the equipments that I have in mind, in order to provide some context.

This are the speakers that I’m planning to build, in fact, already purchased the first drivers :),

3 way: 12" woofer + radial horn + super tweeter

(the exact drivers are the showed on the third option plan)

Active Crossover:

F15-L appears for reasonable prices from time to time...

Now, the amp it’s the big question?

I noticed that if choose the multichannel amp, mostly of then are designed for home theaters or pro audio... what about HiFi Stereo?

Appreciate very much suggestions, vintage or actual in production...

This Accuphase from 2001: http://www.accuphase.com/cat/px-600e.pdf

Appears to be the logical option, when considering the crossover, but this don’t appear very often, but according to my researches, they appear from time to time in Japan, found some in online auctions that was sold for prices not so extravagant... still costly, but, considering the price of acquire separated amps for the same performance level, still worth it..

Anyway, that’s it, appreciate very much all the thoughts about the subject, advices, amps suggestions...

Many thanks, best regards.

Hello guys, thanks for the contribution on my thread here, really appreciate.

As I said, I not started to build the loudspeaker yet, still ordering the speaker’s drivers, when the building process starts with the woodworker that I’m in contact where I live, (experienced speakers builder guy that I had the look to find, it’s difficult to find one where I live), i will indeed post on DIY, some doubts that may appears around the subject.. It’s a great Forum.

My question here is related with my research about using multi channel amplification... instead of separated amps...

So Mr. Bache, I think I not understood fully your suggestion, can you elaborate more please?

My point is cut costs with a multi channel amp as first solution, not buy 6 separated amps, but let me know, what amps are you talking about? any particular models?

Thanks sir.
For example:

hat I wondering is how this multi channel specific designed for HT are voiced you know? if there's something on their design that is more suitable for movies sounds, effects, and etc.. and not so refined for music playback only, from vinyl CDs, and etc...

Maybe this happens with some models, but is not a common thing in all?

Thanks!
well design  sound system --speakers plus amplification MUST BE good for any type of  source or genre 
My suggestion depend from you budget , i can  recommend a lot, 
 what you prefer  class D, class A or AB ?
