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

In your situation you could use one amp for the woofers and one for the mid/treble or you could  use a single amp each for the L and R speaker.  I would try both ways. 

Bridging allows for greater watts at the expense of current. Not good for low impedance speakers. 

I would be concerned about the power compatibility of those amps with that speaker even using both amps. What is size of room? 

Which amp were you planning to bridge? Stereo tube amps aren’t usually bridged; their sides are run in parallel for mono. My VAC 200iQ tube amps are like this, and it results in a huge upgrade in performance (at the cost of 2 amps versus 1). I’ve tried bridging a SS amp I really love (Phison A2.120SE), and it honestly sounds better in stereo mode. Bridging is much more tricky, and more likely to degrade sonic performance for the extra power.

I tried bi-amping instead of bridging SS amps, and that was fun but nothing life changing. Tried both vertical and horizontal bi-amp. You need identical amps for vertical, and (at least) gain matching for horizontal. I simply still prefer to run that amp in stereo (single amp). Biggest difference I’ve heard so far was running the tube amps in mono/parallel mode (haven’t tried bi-amping them).

@kellymack,

I would bi-amp. That said it should not be undertaken without first asking the manufacturer’s advice.

When I horizontally bi-amped my speakers with an analog active crossover design by the same manufacturer (of the speakers) it brought my speakers three notches above the passive crossover in sound quality. 😎

i have considered a small sub woofer, but haven’t made a move on it. 

@kellymack ^That^ often gives the most boost.

And if done right it is more like bi-amping… Basically the sub notes get largely  striped off, from the main speakers.

if you already had two stereo amps, then just try it, but $ for $ a sub is usually the most effective.

@kellymack 

You are on the right track getting a sub. 35 watts is probably not enough to take care of the entire bottom end, but if you roll them off at say 80hz to a subwoofer or two will amaze you!  If you go with REL or similar, that use your amps speaker feed, you shouldn’t need anything else. They can control where the speakers roll off and the subs roll in.

Let us know what you decide to do.
