Two Sunfire Signature's wired together?

Lawdog, Let us know how it turns out.

You can count on it!

Well I'm half way there! I got the two Sunfires back from Randy at Sunfire whjich turns out to be less than 10 miles from my home. They are restored to original factory specs and updated. I now must biamp the Carver Amazing Loudspeakers, original edition. I thought the cheapest way to do so would be to connect the ribbons through the passive crossover within through the existng speaker binding posts and add a second set by soldering a piece of good bass speaker cable like the old Tara Labs Temporal Continuum (which should make the bass drivers much stiffer and produce tightly controlled bass) directly to the woofers bypassing the crossover altogether. .

But it must connect to an electronic crossover between the preamps second outputs and the amplifier driving the bass signal. I've many hours trying to check out which would work the best by jumping around on the internet but the best ones are apparantly no longer made.

Which crossover works best with ribbons that are crossed over at a point around 160 and the woofers nearer 200 so that the 4 12" woofers will "augment" the ribbons below 100? That requires some pretty complex equalization of the bass frequencies. I don't think the standard Rane or Ashley is going to make the nut.

Any helpful suggestions or ideas will be gratefully appreciated!

In the meantime I have the two Sunfires smokin' with one channel of each driving each the two speakers--which ain't bi-ampin' but it's already blown me away. Never heard anything even close to this good. After about 24 hours playtime they suddenly broke in with an almost audible pop--and it hit a new dimension altogether. Out of this world!

Lawdog, I don't understand how you have those two Sunfires wired up. I would appreciate if you could go into detail. If I get a second Sunfire, I will not be biamped. Thanks in advance.

Can you discribe the difference you hear going from one Sunfire to two? Is there any difference at moderate listening levels?

I've used two Sunfire Signatures bi-amped with two different sets of speakers and the results were very different for each set of speakers.

I first used a pair of Sunfire Signatures to bi-amp a pair of Infinity Kappa 9....very inefficient notorious hard-to-drive power hogs. Bi-amping the Kappa 9 were a world apart from using a single Sunfire Signature amp. The improvements were dramatic.

I then bi-amped a pair of Infinity Rennaisance 90 speakers.
It was a complete waste of an extra amp. Bi-amping was indistiguishable from using a single amp with these speakers. They are much more efficient than the Kappa 9.
