4 amplifiers to drive 1 pair of speakers?

Hi

Sorry I am still quite a young audiophile (less than 1 yr old)
Was wondering if its possible to use 4 amplifiers (eg 300b which is quite low powered) to drive a pair of speakers? 

I.e. pre amp output --> Y splitter into 2 different 300B amplifiers for each channel. Each amplifier can take either the top 2 or bottom 2 binding posts of the speaker.

My speakers are 90db 8ohm (more like 4ohm in real life), and im afraid that 2 300b PP amplifiers ~18W class A is insufficient.

Thanks!

Bi-amp with valves units.. The only issue for me would be heat. It's tough enough to deal with valve amps in the summer months, much less 4 of them.. You might want to rethink that one.

Eric offered SS for BASS duty that is a lot better ides. COOL running class Ds will certainly liven up the joint.. I quit using valve amps for bass duty 20+ years ago.. They work better NOT doing bass. Pretty simple.

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!
