I have just discovered that my Moviestar 100's have been putting my Yamaha RX-V373 into power protect mode and will have to be replaced.

I was sold the whole package from HN and was assured that they would work fine together but after a second trip to the repair shop the tech pointed out that the Moviestars are 4 Ohm and the receiver is only rated to 6 Ohm. I didn't know enough about impedance to check for this first but HN have been good and will replace the speakers/receiver to something suitable.

The easiest solution seems to be to replace the speakers but my wife really likes the shape and size of them so I am reluctant to swap them. I would be prepared to upgrade the receiver though. Having a look around I see the Yamaha RX-V673 is good and has this in the specs

  • 7-channel 1,050W = 150W x 7 (4 ohms, 1 kHz, 0.9 % THD, 1 ch driven)
  • 630W = 90W x 7 (8 ohms, 20 Hz-20 kHz, 0.09 % THD, 2 ch driven)

Does that mean that it would be suitable for these speakers? What does it mean by "1 ch or 2 ch driven"?

If anyone can point me towards any other receivers in the $1000-$1200 range that would be awesome.

it means those specs are only achieved with 1 or 2 channels being fed a signal.

basically playing number games to produce impressive specs.

when fed a 5.1 signal as in normal use you can expect far worse results.

ditto the power rating into 6 ohms instead of the more standard 8 ohm.

6 will make bigger numbers.

go back to hn and get a set of 6 or 8 ohm speakers.

try wharfedale diamonds.

overall a pretty pathetic result for the yamaha.

they really don't build them like they used to.

I'm not sure how many receivers in a suitable price range are stable down to 4 ohms on a regular basis... I know Pioneer's LX86 is, but that's a 5k receiver.
The speakers should be fine at conversation type volume levels, but when you crank them you will either hurt the amp, or the speakers. They really are a little speaker designed to emphasize TV audio and help with movies.
If you're after something that's easy to drive, but offers a compact form factor, look at Klipsch... they're well known for running on the smell of an oily rag.

The wife might approve of these then.

I'm currently using those and pretty happy with them; running well off an v373. I'm thinking of getting a couple of klipsch floorstanders for the fronts though (or even a pair of bookshelf speakers, though not sure if that woud have much effect - gonna have to go listen to some if i can)
