B&W 683 Series 2 (x2), B&W 686(x2) and HTM61 S2

The 683 S2 features a Decoupled Double Dome tweeter – technology evolved from Bowers & Wilkins CM10 speaker. The double dome design uses an extremely thin aluminium dome for lightness, surrounded by a thicker aluminium ring for rigidity. The result is a far more precise treble performance. And while the tweeter looks like it’s part of the main speaker, it’s physically separated in its own gel-filled cavity, so performance isn’t hit by unwanted resonances or vibrations, for a more natural, spacious sound.

Serious and accurate bass performance is equally vital to such a room-filling speaker. That’s why the 683 S2 features a new bass driver construction method, using a similar method of bracing to the tweeter with twin layers of aluminium. The richer, distortion-free bass response is sumptuous.

The HTM61 S2 now features a Decoupled Double Dome tweeter, ideal for delivering the clarity needed for dialogue. The double dome enhances rigidity without adding weight, for a more precise response, while decoupling the tweeter from the main enclosure removes unwanted resonances and vibration. The result is absolutely clear.

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.
