Am I wasting money on the theory of Bi-amping?
As a long time audiophile I'm finally able to bi-amp my setup. I'm using two identical amps in a vertical bi-amp configuration.
Now me not fully understanding all of the ins/outs of internal speaker crossovers and what not. I've read quite a few people tell me that bi-amping like I'm doing whether it's vertical or horizontal bi-amping is a waste since there's really not a improvement because of how speaker manufacturers design the internal crossovers.
Can anyone explain to a third grader how it's beneficial or if the naysayers are correct in the statement?
man you guys are still at it. It works, so depends on your situation, if you can get a hold of it, try it. If you don’t hear the diff, sell it. I have 4 AHB2 bi-amp on mono-mode to JBL 4367, which the crossover network is well built even its passive. Been building system for 20+ years, and first time ever, I do not foresee even the desire to make a change. |
@asctim , I did just that. Starting with 1 AHB2 with a different speaker, notice the bass is tighter and it was not sterile/cold sounding. Smooth, highend, you are hearing really the upstream/preamp. Then got another one, mono mode to each 4367, sounding great, everything falls into place. so I ordered another pair for my secondary system, but tested it biamp mono in JBL first, the realism, the "air" is just unbelievable. Diff between ya I can see the imaging, to "where did that sound come from!". Needless to say I left the pair there and got another pair for second system. Amp hiss, is not a normal thing. It's a product of "too much gain in chain" + "not so good amp". I can crank up to over-concert level, and theres no distortion. |
Nope. You are describing the scenario of what a normal system with an acceptable noise already present in the chain, but not when you are using absolute silent components. Lookup the AHB2 review from stereophile, the amp not only can adjust the sensitivity (9.8V RMS/22dBu, 4V RMS/14.2dBu, 2V RMS/8.2dBu), it has such a low distortion number, akin to the testing equipment that bench test the amp itself. If your upstream is absolutely silent, if theres noise/distortion in your horn, it's something else. Uber horn lovers pay big bucks for expensive tube amps, not just for it's tone/sound, more often it's for the silent. And they do directly connect to the compression driver with active setup. |
