Tri-amp 3 way speakers, still worth if using a multi-channel amp? (HiFI Stereo)
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! |
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!). |
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. |
I think I have found the answer for my question, please let me know if I'm correct: Consider passive crossover. So if I choose to use 1 M-73 to amplify 4 speaker's drivers using the 4 speaker's terminals (A left horn + B left tweeter / A right horn + B right tweeter), and select A AND B speakers selectors to work at same time, i will be bi-wiring, that means: each amplifier's channel will be responsible for divide their power for 2 drivers right? this can be done only if the drivers don't go bellow 8ohms, correct? I realized this is not a 4 channel amp, it's a 2 channel stereo amp, I was thinking it was a 4 channel amp, with 4 separated blocks, with each speaker's terminals connected to each block, just because of the inside look, (appears that are 4 separated amp blocks), but is not, it's just a stereo amp, correct? |
In the case of effectively bi-wiring, so long as your original speaker was a match for your amp, you are good. For instance, say you have a pair of Monitor Audio Silver 6's. Nominally rated for 4 Ohms. Your amp, rated for 4 Ohm speakers, will be fine if you bi-wire (A+B) that single pair of speakers. However, take 1 pair of speakers at 4 Ohms, and another pair, also at 4, and you'll have a problem with that amp. Best, E |
