Many smaller amplifiers vs. bigger amplifiers.

I want to make an high-end amplifier for my home theater system and I have a dilema. I ask your opinions about this:

I have 4 bass speakers (Visaton 12 inch/ 150w rms/8ohm ) for subbass loudspeaker, all speakers working for mono subbass channel .

I have 4 amplifiers module 150w/ 8ohm and 2 amplifiers module 300w/4ohm , all module at same quality .


What is the best option ?
1. Every speaker driven by a module 150w/8ohm , or
2. Two pair of speakers in parallel driven by two module at 300w/4ohms.

The costs are not important . I want to know your opinion or experience about sound quality ( generaly speaking ).

Any coments or sugestions , please .

Regards,

This is what I like if money and space is no object.

One amplifier bridged per speaker
(I like bridged so I can utilize both rails for headroom)

*OR*

One amplifier bridged per crossover point.

I was using multiple small 200w mono amps with +40v/-40v rails.

But, I'd like to take this to the next level someday and go
for +100/-100 rails - heheh

This might not solve your problem, but I believe that
the best approach is multi-amping, in which each driver
gets its own amplifier and filtering is done before the
amplifier.

Lowest distortion, highest output approach.

Also, maximal tweak-ability.

:cool:

I concur 100%. My system, if ever finished :D , with have 6 valve amps (monoblocs) and 8 SS amps (the last to drive 4 woofers and each coil on dual VC subs).
