Even though the W667 is so inexpensive you can use it in any (or every) room in any home, it still delivers that classic Proficient sound. A polypropylene-cone woofer cranks out solid bass performance, and a soft-dome tweeter produces clean, sweet highs. High sensitivity gives you the same volume with less amplifier power.

The W667 may be their least-expensive in-wall speaker, but it still delivers the sound quality you expect from Proficient Audio.

Its high quality 6½ inch polypropylene-cone woofer pumps out the deep notes all the way down to 45Hz, with low distortion and a clean midrange. The ¾ inch soft dome tweeter has a smooth sound you wouldn't expect in this price range.

With a sensitivity of 90dB, the W667 needs only about half as much power as a typical speaker. That's especially important in budget multi-room installations, which sometimes use very low powered amplifiers. Because the W667 uses the same cutting template as Proficienct's other 6½ inch in-wall speakers, you can easily mix'n'match Proficient models without worrying about cutting the wrong size hole.

Includes Thin-Bezel Grilles held by Neo Magnets.
