Anybody have an actively multi-amplified system?


Hello,

I am one of the very rare breeds that has a fully active system, 6 Jeff Rowland monoblocks running Klipschorns with an Accuphase F-25V electronic crossover in front of the amplifiers, and the passive crossovers taken out of the speakers. It sounds absolutely phenomenal, like nothing else out there. I've been in the business 35 years and have yet to meet anyone (in home audio at least) who has done something similar. It's done all the time in pro audio, yet nobody talks about it for home use. It's widely known that an actively amplified setup simply IS better than any passively crossed over speaker, since the dividing is done before the amplifier, each amplifier only amplifies a certain frequency range, and then the output of the amplifier is connected directly to an individual driver with nothing in between. If anyone has such a setup, is interested in learning more about one, or wants to throw in their 2 cents, please do! It's about time we did talk about this, and I can't believe in all these years more companies haven't actively (pun intended) embraced this type of setup. Also, if anyone has crossover cards for an F-25V crossover, please let me know!!!

Oft amazed at the complexity of execution.  Nearly 50 years of audio experience and enough past pieces to fill a small audio store shows so many problems have been well solved producing a nice facsimile of live performance.

The debate over active should be mostly a dead thing.  ATC and others have executed this well and on a level palatable to hardcore audiophiles.  Active is not necessarily bright, forward, sterile, non-imaging and/or fatiguing....or any of the other nasty claims.

It is a matter of proper execution.  And yes, I own fully active floor standers which image well, are non-fatiguing and produce dynamic immediate vocals and instruments.
Hello from 2019! :)

I’m seriously considering this, instead of build the passive cross over for my speaker project...

This multi channel amp and active crossover, would like to know more about if this example can be a more easy solution to divide the frequencies for the speaker’s drivers, instead of build the passive crossover for the woofer, radial horn, and super horn tweeter, as is suggested on the Fostex speaker’s plan.

More, easy, straight forward configuration, but more expensive for sure... well this amp, preamp and active crossover from Accuphase I found some to sell occasionally on the web, sometimes the preamp and the active crossover appears at a more reasonable price in Japan I think..

Anyway, what do you think about this solution for a 3 way loudspeakers? 

I noticed that on the PX-600 brochure, Accuphase shows a picture example with this devices used with 3 way speakers system, with the exactly same design of the ones that I will start to build, take a look... maybe this says something? probably a good match?

All components are from 2001, then, they are soooo vintage to worries about repair, recap, and etc, if considering very well cared units, the F25 is from late 90’s but was re-released in 2005.

Let me know your thoughts about, very interesting stuff....
