Should I bi-amp or bridge my amps to feed my speakers


I have an older pair of Audio Physics, they have woofers on each side and a mid and tweeter on the front. I have (2) identical tube amps running in triode mode at 35 watts each. I was thinking to bi-amp the woofers on one amp and mids, tweets on the other. Wonder if anyone here has experience with this? Any advice or input is appreciated..

I have heard those speakers with and without subs at a dealer in Portland and the spatial difference was not subtle. They were also spread farther apart from each other than "normal" and severely toed in. I don't remember which amps were driving them but I'm sure there was more power than the 35 wpc you are using.

I am not sure that we know that for sure…

The amount of power in the 20–80 Hz region depends on the music, and the system with the subwoofer May have been <35 wpc, and the sub well over 100 watts.

We sort of don’t know, but it is possible to significantly lower the amount of power by adding the sub.

Can you further describe the “not subtle” difference?

The room is 14 x 20. This amp is already louder than I can handle. Once in a while I turn the volume up half way on my pre-amp. Sounds good, but don’t need it that loud. I just want a little more bass. I’ll try bi-amp ing this weekend. According to the manual bridging is straight forward and easy.

I feel like an idiot. I bi-amped my speakers this morning and it’s night and day difference, sound stage is more distinct and the speakers have disappeared.
