Your receiver might overheat causing the outputs to blow/short ,possibly passing a lot of voltage to the Theil's blowing them out.Power amps that can drive 4 ohm speakers would on my priority list.
Thiel speakers--can you power them with reciever?
Or do they really need a separate amp?
I am getting the bug to make a speaker change(for my front L/R speakers), and from what I read, it seems like a used set of Thiels may be up my alley in terms of sound characteristics.
But, looking at their rated specs, they are rated at 4 ohms, with a minimum of 3 ohms, and have fairly low sensitivity at 87Db.
I'm also looking at used Vandersteen, Eggleston, Merlin. It seems like most of these have similar ratings to the Thiels.
Any thoughts? I am currently running my 5.1 system off a 130wpc receiver, but I do have a 5 channel power amp I could use. The receiver is not known for having much output into 4 ohm loads.

Here are test results on Ultra 2 receivers.Anything over two channels kills the power.7 time 4ohms will probably kill the receiver.Denon AVR4308 140 watts.Drops to 111 watts X7 at [email protected] 20-20,000,might not be possible.Test link below.Yamaha RX-Z9 175 watts.test out at 138 watts X7 @1khz.Not 20-20,000 either.Typical SELECT2 acording to S&V. I can't think of any receiver that will give a full bandwith power with all channels driven at 4 ohms!
