Quote: Ok I think you mean using 2 amps in a Vertical or Horizontal-(not bridging the amps) configuration.

James, how can one use two unbridged 4Bs in a vertical bi-amp? wouldnt they need to be bridged to make this work?

Hi - I guess we have to define our terms - maybe I'm confused.

Vertical bi-amping is when you use 2 stereo amps BUT use a single stereo amp on each speaker and use 1/2 of the stereo amp to drive the bass and the other half to drive the mid/tweeter.

Horizontal bi-amping is when you use 2 stereo amps but 1 stereo amp runs the bass panels and the other stereo amp runs the mid/tweeters.

Hi James, I agree with your definition of the horizontal and vertical bi-amps. I think I've sorted our the confusion i was having with the vertical bi-amp - in this situation, using two identical (4B type) stereo amps, and a pre-amp with two sets of outputs, we would:

-place one stereo amp ('amp A') next to the left speaker, and place the other next to the right speaker ('amp B')
-connect one of the left channel outs of the pre with the left channel in of amp A, and the other left channel out of the pre to the *right* channel in of amp A
-connect the left channel out of amp A to the bass, and the right one to the panel of the left speaker
- -use the same process to connect the right channel outs of the pre to amp B and to connect the right speaker to amp B

Are we on the same page? I've never tried this style of bi-amp as I've never had two identical amps in my system at one time, but it makes good sense.

Hi Viajero,

Correct - same page - exactly as you suggest.  I have always found that the closer you can place the amplifier to the speaker the better so this arrangement optimizes that condition.

Yes, this is definitely the way to go if one has two identical amps... exactly the same amplification provided to the speaker as in a horizontal bi-amp, but the benefit of shorter speaker cables. Thanks for clarifying!

Sorry to bring this up again however I am wondering if it would be preferable to vertically bi-amp with another 4B-ST or go with a new single unit 4B-SST?

Can any of you with experience let me know please?

Also, would the sound of the SST series be a better alternative as this is what I am looking for of course.

Thank you
