Help with Carver

Hi I had asked earlier on the best hook up using 2 TFM Carver amps.I finally got hold of Carver tach and was told that if I switched the carvers to mono and ran them to my 3.1tls that the amps would become unstable and cause damage because the 3.1tls are under 8ohms.Does my A1 cable take care of this problem or do I have to come up with another way to hook up both amps?If so what are the options and how do I do it?

as far as I know, the A1 interconnect does nothing with impedance issues. If the 3.1 Tl's are 4 ohm, I could see how there will be an issue. Can the 3.1's be biamped?, if so, biamping would be your best option for lower impedance stability. you will have more than enough power to get the job done. the carver tfm's are common ground, but you have an A1 cable anyway so the point is moot.
if you have the option, biamping is the way to go here.Living Room 2 Channel -

Lou is correct, the AI-1 has nothing to do with impedance. The Carver tech is also correct in that you can't run less than 8 ohm loads on bridged amps.
The 3.1TL's (6 ohm nominal) have two sets of binding posts, so you can bi-amp them.Political Correctness'.........defined

Bi-amping will give you a nice power (and quality) increase and take care of the impedence problem while not requiring the AI-1 cable so long as you do a horizontal biamp. Sounds like the way to go to me.

cAgree with all of the above.
While the Carvers have GOBS of power if bridged, they CANNOT be run w/ less than an 8 Ohms nominal load.
Now if you horizontally bi- amp the speakers, ie run one amp for the highs and one for the lows, you will double the power to the speaker, enjoy Alot of headroom, better clarity, better dynamics, etc., etc....
If you vertically bi amp them, you'll still need an AI-1 interface. -
I talked to Polk customer service.They said to run the left channel to one amp then run it's right side to the high cross over and the left side to the low crossover,Then run the right channel to the other amp and do the same wiring.Does this sound right? Or is there a better way? Thanks again

you might be wording it wrong. take one amp, wire left channel of the amp to the low freq binding posts of the left SDA, then the right channel of that amp to the low freq binding posts of the right SDA. then take the other amp, wire the left channel to the upper freq binding posts of the left SDA, and the right channel of that amp to the right SDA's upper freq binding post. this is called a horizontal Biamp.Living Room 2 Channel -

What you are describing is vertical bi- amping. You lose the common ground, and will need a AI-1...
Lou has it straight. -
I have the A1 cable So this brings me back to which is the prefered way to set this up.I thought that one amp for the highs the other to the lows was best but Polk told me to go with the vertical bi amping.

hmm, I say try both. I dont know of a benefit over the other offhand, maybe some of the guru's will chime in. seems more natural to me to horizontally biamp. if you do verticle, make sure you use that a1 cable!! or roast marshmallows over the amps as they sizzle.....literally

I wired the new tfm24 in last night.I decided on horizontal bi amping .All I can say is thanks for the advice the results are fantastic.The clarity,the sounds that I am picking up that did not seem to be there before has made me want to listen to all of my discs and albums again.Thanks again for the help.

Cool. Happy to hear you like it.
I've tried both, I like horizontal versus vertical myself. Just seems to work better...
