Hello all,


During construction of my brother-in-law's house he had them install speaker wires for a pair of outdoor speakers which I've just finished helping him install on the back porch.


They routed the in-wall speaker wire to an outlet plate (next to the back door) where a wall mounted volume control should go.


The builders didn't install the actual volume control unit though, so I've been looking for some on the net. They seem to range from $35 to $50.



I was wondering if anyone had experience with these controls. Specifically:


-do I need to closely match the wattage, voltage, and impedance of the control to the amplifier?


-do those prices seem about right for what I am looking for?



The receiver driving the outdoor speakers will be 85Wx2.


Here are two I've found:

Thanks for any advice.

Rick,


FYI. The controls that Johnla specified are rated at only 50 watts per channel. You said your receiver/amp is doing 85 watts per channel.

Well, is the receiver/amp REALLY doing 85WPC, or that just what it is rated? Depending on the brand, it could be putting out a whole lot less, and 50WPC is probably fine. Furthermore, if you have it routed through an impedance matching switchbox, it could be getting less still.

I was a little off, it's actually only 80W/ch. It's a Denon AVR-2000. I don't believe it's routed through an impedance matching switchbox.


I appreciate the continuing info.

Parts express also has them in models, rated for higher wattages than the ones I linked to. But of course, those are sold for a higher price as well. My guess is though, that the 50watt ones should work OK with a 80watt amp/receiver.

I use a rotary one for the bedroom. Cost about $25 at Lowes 3-4 years ago. Probably rated 50 wpc. Works fine - only thing is it appears to be power linear, not sound level linear - i.e. top of dial is -0 dB, middle of the dial is -3 dB, 1/4 way up dial is -6 dB, and the first notch is about -10 dB. I end up using it as off/on more than volume.

I wouldn't be too worried about the 50w control on the 80w amp.


Amp manufacturers are NOTORIOUS for overrating their power outputs.


And even if the amp could put out a solid 80w continuous, will you really be driving your speakers at maximum volume continously?
