1-inch (25 mm) soft dome tweeter/4-inch (102 mm) aluminized woofer.
Bass-reflex design with flared, rear-firing port: Increases system efficiency and bass output.
Waveguide: A unique tweeter faceplate that provides more uniform dispersion in the critical frequency range of 2-10 kHz. Dynamics and clarity are enhanced while distortion is significantly reduced.
Centre-plug: Replaces the typical dust cap and eliminates cone breakup, for a woofer with faster “attack” and tighter, more natural bass.
Aluminized woofers: Increases driver cone rigidity for solid bass reproduction.
5-way binding posts: Allows for multiple connection options with wire up to 12 gauge (AWG).

Time Lens Technology-The acoustic centers of the tweeter and mid-bass driver are located in the same plane for superior imaging
PowerPort® a patented Polk technology, extends the low frequency mid-bass driver response as it decreases air turbulence, and eliminates "port noise" and bass output losses up to 3 dB.
3/4" Silk Dome Tweeters for crisp, clear imaging and smooth response that's never tiring.
Combination Keyhole Slot & 1/4" x 20 Threaded Insert fits all aftermarket ceiling and wall brackets for ultimate flexibility

Small is beautiful. The 686 S2 is the most compact speaker in the series, but don't underestimate its power and precision. That's thanks to a new Decoupled Double Dome tweeter and improved design.
An ideal bookshelf or wall-mounted speaker, the 686 S2 is designed to fit into any space and still sound perfect. Its main driver is a 5-inch bass/midrange unit which benefits from a new 25mm voice coil which makes for a higher sensitivity speaker with bass more suited for placement near a wall.
Bass performance is vital but can often suffer in smaller speakers. Not in the 686 S2, however. That's because a front-firing Flowport, dimpled like a golf ball around the aperture for smoothly regulated airflow, delivers superior bass response without the risk of rattle. Its placement ensures the speaker cabinet is slimmer than predecessors and can be wall mounted without affecting performance.
Like the rest of the range, and despite its smaller size, the 686 S2 also features a Decoupled Double Dome aluminium tweeter for superior high-frequency response. The 686 S2 even features a built-in bracket for easy wall mounting, although this small, versatile and precise speaker sounds great anywhere.
