4 amplifiers to drive 1 pair of speakers?

What are your speakers? That amping scenario is unwanted complexity

Does your experience come from working in live concert, pro audio sound staging? If not then I’m not clear what your home audio objectives are. From a quick power ratio calculation, what you’re doing will quickly lead to equipment failure—meaning dollars wasted. 

why would anyone want to use 4 amplifiers to power a pair of speakers?? awhile back i did have 2 amps powering 1 pair of speakers. 1 amp powered the low end and the other amp powered the high end!

Hi Erik and Oldhvymec,

Thanks for your suggestion for the bi-amping with solid state for bass. However I note from some reviews eg Steve Guttenberg it isnt that easy to get a good matching of the amplifiers (eg he tried with zen triode at the top and schiit aegir at the bottom end) and it wasnt a good match.

Hence I was apprehensive about bi-amping. I know some solutions eg Mcintosh MC901 sounds really good, but those are out of my budget and also it is a pre-matched solution.

Thanks!

Hi 

I am using kef reference 5 with recommended 50-400W needed to power it. Most of the impedence on the chart is around 4ohm instead of 8 ohms. Lowest dips to 3.2 ohms. Although it is 90db at 8 ohms, there are 4 woofers, 1 tweeter and 1 midrange on each speaker - hence may require more power/current. 

From what I understand tube amps (or at least SET amps - not 100% applicable here as they are PP) should not be pushed past their 25% limit to have a good sound.Hence for a 18W 300b PP monoblock amplfier to drive my speakers will likely be insufficient. Hence exploration of 4 amplifiers and whether anyone has tried it before/if it is feasible. 

@scchengmus what do you mean by power ratio calculation? Why will there be equipment failure? :) sorry am not well versed in that

Thanks
