Vintage AR3 Speakers with AVR and Power Amp?

517 Views 6 Replies 3 Participants Last post by  Stereojeff
Hi. I'm putting together a system with older components and would love any advice.

First, the set up: I recently restored a lovely pair of vintage AR3 speakers, inherited from my uncle. They sound great! I currently have them connected to an old AVR (Yamaha RX-V467). I haven't connected any other speakers apart from a subwoofer (don't need surround sound).

The audio signal goes from the TV to the AVR via HDMI. I stream everything through the TV (not a gamer, so no other inputs). I might add a CD player at a later stage.

First question: is it risky to drive the AR3s with the AVR? It's a big room but I don't listen at very high volumes. I've also set the speaker size to small and have a subwoofer. There is no sign of clipping so far but when I turn the volume up a bit, certain sounds seem to 'ring' and sound harsh (e.g. high trumpet notes, top notes in Opera arias, etc.). My main worry is that the AVR will blow the tweeters in the AR3s. Is this a legitimate concern?

I have been told that due to the low impedance AR3s, I should connect a separate power amp. So, a friend gave his old Cambridge Audio Azur 640A. It has the right specs for the AR3s. Only problem is that the Yamaha AVR only has a pre out for subwoofer and back surround. There are other Audio outs but 'digital audio cannot be transmitted from these jacks'. Is there any way to connect the Yamaha AVR to the power amp? I really don't want to spend the money on a new AVR when all I'm going to do is drive stereo speakers and a subwoofer.

Hope this all makes sense.

Any opinions welcome. Thanks for your time.

For an inexpensive trial, you can purchase a High/Low converter from an automobile sound shop. These hook-up to the speaker outputs of your receiver and output a low-level signal via RCA jacks to send the signal on to your amplifier. Should work out just fine.

Thanks Jeff. I did see those car audio converters but was worried they aren't designed for bigger systems. Any specs I should look for (Watts per channel, etc.) Or are they just plug and play?
The AR-3s were a great loudspeaker in their day...
But they had a sealed enclosure, low impedance and sensitivity..
All that requires a healthy high-current amplifier to drive them to louder volume levels...

Just my $0.02... ;)
Thanks. Can't quite work out how to tell if the amp is high current from the specs provided by manufacturers. All a bit beyond me :)
The Cambridge Audio Azur 640A is a quality amplifier, with good power into 4 Ohms.
It should drive the AR-3s just fine in an normal size room @ reasonable volume..

Just my $0.02... ;)

These devices are plug and play. No reason to overspend.
