Just buy three stereo amps (Carver TFM 15CB) on Ebay cheap, add a good pro x-over and you’ll be good to go! I have that same Carver amp (Goodwill $25!) and it is indeed excellent! I have it connected to my KLH Nines and Ohm Sound Cylinders. The idea that spending lots of bucks for an amp and getting "better" SQ is nonsense (like a lot of beliefs here in HiFi Land!).
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.

Hey guys, please, appreciate if someone can solve a doubt of mine, when considering this amp: http://www.audioscope.net/pioneer-m73-class-power-amplifier-p-1759.html in a multi amplification situation.
Here's the situation:
Considering a pair of 3 way loudspeakers, 12" woofer + radial horn + super horn tweeter, it's possible to amplify the 2 radial horns + 2 super horn tweeters, with just one Pioneer M-73?
I'm asking because I see 4 A + B speakers terminals on the back, and on the front, I see that is possible to select the A + B speakers at the same time...
It's possible? or I'm interpreting this wrongly?
Many thanks! Best regards. |
Hi cosmicjazz So keep in mind that those connectors are there purely for convenience. Besides the switch, there is no extra circuitry. You don't get more of an amplifier by using A+B. So it is up to you to ensure that the impedance of the A and B speakers does not drop below the amplifier's recommended minimum if used simultaneously. This is typically 4 Ohms. One possible use is to bi-wire. That is, remove a speaker's jumpers and run a separate cable to each input. But again, you don't get more amp. Best, E |
Let me put my doubt in a more organized way: This is the hypothetical situation about a bi-amp application with a particular amp. Here's the amp: http://www.audioscope.net/images/pioneer_m_73-2.jpg http://www.audioscope.net/images/pioneer_m_73-5.jpg Here's the situation: Considering a pair of 3 way loudspeakers, 12" woofer + radial horn + super horn tweeter, it's possible to amplify the 2 radial horns + 2 super horn tweeters, with just one Pioneer M-73? I'm asking because the amp have two A Left speakers terminals + two B Right speakers terminals, and on the front, I see that is possible to select the A + B speakers selector at the same time, and also, when you see inside the amp, appears to have 4 separated channels, see the picture: https://1.bp.blogspot.com/-CF-iRPLZn14/WJ3TWSkkQeI/AAAAAAAAAQs/qKSR0H8hr1od-DtObBTf4ntTs1LE6mY3gCLcB/s1600/Pioneer%2BM%2B73%2Binside.jpg I will be in fact bi-amping? Many thanks, best regards. |
