Back from mowing the lawn.

57 - Looking at the manual, the RCA input could connect to the PRE-OUT of an receiver.

JAG94 - The speaker' input impedence is 10K or 10,000 ohms which is what you would expect for a low level input. The speakers are meant for portable PA systems and any receiver you buy will have an unused amplifier section.
forgive me for my ignorance...

does that mean i can find a way to make it work?

You need a receiver with PRE-OUTS. The sub should be fine because most are self-powered and (almost) all receivers have an LFE OUT. Or you can use a pre-amp if you can find one with Dolby and DTS decoding. That's more specialized and expensive. The speakers are for commercial use and any sound engineer could hook them up in 30 seconds.


There's other ways to hook up the sub. In a normal PA system you'll run from the mixer to the speaker (via XLR) and from the speaker to the sub (via XLR). (Repeat for each channel.) The manual describes other approaches but assumes you're familiar with audio gear.

The speakers are meant for portable PA systems

These speakers are meant for near-field monitoring of music & sound in a recording studio. They are also active/powered, meaning they have built-in amplifiers.

... any sound engineer could hook them up in 30 seconds.

... but not to a home-theatre receiver (in 30 seconds)

Update:

So I talked to both the speaker manufacture and Yamaha (AV manufacture).

KRK Speakers said that cutting of the RCA plug tip and exposing the bare wire = not a good idea. the guy i spoke to didn't have much info about setting up the speakers with a consumer receiver for home theater, and gave me a number to someone who would have more info, but I didn't call yet.

Yamaha, says that the Pre-Outs on the back of the receivers model numbers RX V863, and RX V665 (and up) WILL SUPPORT speakers with their own power source. He said the pre-outs do pass audio signal, so as long as your speakers have their own power source, it will work.

So my next move is to pick up one of these receivers (which are substantially more money). I found one... The RX-V861, brand new, b-stock item on ebay for less than half the price of a brand new one. So here we go. I'll let you know when I get the new receiver (hopefully today), and set it up.

Thanks to all who gave suggestions and helped.

I got the Yamaha RX-V861, and all is well. The pre-outs work with the powered speakers. and they sound fantastic.

Thanks again for all the help.

Thanks for getting back to us and letting us know.

3. Even though the 665 has these pre-outs, you need to confirm with the speaker manufacturer that this would work - it may not.
Yes, the 665 and up would do the trick using pre-out of the receiver to powered speakers. Pre-out from a mixing console or from an AVR are still pre-outs.

Indeed, powered speakers are like having dedicated amps for your speakers and therefore give the best results. Also to be considered, powered speakers usually cover the entire spectrum of the audio frequencies thus providing you with the lows up the the highs and can be easily blended with a powered subwoofer if subsonic frequencies are desired otherwise they can be used without any external subwoofer. Also to mention that powered speakers like powered subwoofer will relieve the workload of the AVR and stand alone amplifier are also usually of greather quality than AVR amps.

I acquired the 6080 partly because it offered pre-out which is perfect for using with quality powered speakers.

Hummmm, you know what those small powered speakers are really interesting: http://www.youtube.com/watch?v=DxXQp3Caavk
