0.6 ohms impedance is excessive for hi-fi
I wanted this to switch between pairs of speakers connected to the single extra zone my Yamaha AVR offers. Unfortunately when it arrived and I measured the impedance across the switch of 0.6 ohms I realized it would be no good for my high-fidelity music streaming application. I was already using 65feet of 14 guage speaker wire with impedance of 0.2 ohms and anything 0.3 ohms can cause noticeable degradation in hi-fi. My system sounds great with 0.2ohms but I won't add another 0.6 just for this switch which I expected to be close to zero.
Disappointing because the ideas is right and a very simple switch is what I wanted, but that impedance is way too high. It seems well made and might work for lo-fi applications such as p/a systems.

Excellent Polk LS sound in in-wall speakers.
I bought these for a small 10ftx10ft room with limited space for cabling or a sound system. I installed them in the corners 4" from the wall with the 'wall-proximity' switch pressed. The listening position is about 9ft from each speaker and the sound is wonderful, in the same class as the Polk LSi15 speakers in the living room. I enjoy listening to jazz, chamber music, symphonic, ambient-chill and these produce a detailed stereo image and very musical sound especially the mids for piano, guitar, sax. I couldn't be happier with the result. Although 'open-box' these were in perfect condition and I feel I got great value for excellent sound quality, and still got full warranty.
They look great and avoid wires on the wall as I threaded the speaker wire down from the attic in the wall cavity. I used rubber from old inner tubes with sheet rock to add extra acoustic barrier behind them. In the next room it sounds like speakers playing in the adjacent room and not as though coming through the cavity.
Note: be sure to leave at least the specified 1.25 cubic ft in the cavity.
The only "equipment" I need in the room is my smartphone to stream Spotify/TuneIn over a Chromecast-Audio connected to my AVR with full dynamic range selected in the Chromecast settings.
Another pair of these work great as surround speakers in a Polk LSi home theater system, filling out the sound for an immersive effect close to the cinema experience.
Very satisfied Polk customer.
