I have a pair of the following: SDA-1A, SDA-2A and a pair of SDA-84CRS. I have the 1A as front channel approx 6” from the wall, 12 foot apart, the 2A as rear channel 6” from the rear wall 12’ apart, and the 84CRS as sound surround.
I currently have them being ran from a Denon AVR3803. It puts out an advertised 125WPC @ 8ohm. I’ve not checked this to see if it is accurate.
My question is about these Polks. What is their efficiency? What is their specs, What power handling makes these really shine without straining them? Any recommendations for power amplifiers? Any recommendation on placement? I use this system as a HT as well as listening to music. I came to this page from advice from other polk fans. Let me know guys/gals!

Both the SDA 1a and 2a start at 4ohm and drop much lower into the 3 ohm range. The CRS may be the same I've never had a set so i have not measured myself. That is a lot to ask of that receiver. You very well may let the magic smoke out of the receiver. Both my Yamaha RX-v992 and Denon 3805 strained with just my SDA2a the Yamaha went tango foxtrot. Those speakers are 4ohm and 86-89 efficient IIRC

So would using that receiver for its pre-outs and getting a solid power amplifier be the ticket?
