Bowers & Wilkins 686 S2 Bookshelf speaker

The 686 S2 builds upon the high standards of versatility and sound quality found within its predecessor, while also improving upon the aesthetic nature of the speaker itself. The 686 S2 is the ideal bookshelf or wall-mount speaker solution for any music enthusiast looking to achieve the best results from their music source. The speaker utilises a 5 inch bass/midrange driving unit, which has been improved with the integration of a new 25mm voice coil. This allows the speaker to act much more sensitive in order to deliver the most precise and detailed sound response. 

The bass performance of the 686 S2 has been improved also. Now featuring a forward-firing flow-port, complete with B&W specific 'dimpled' design, the 686 S2 is able to deliver an exceptionally liquid bass response while drastically reducing potential unwanted resonance and external vibration. The use of a front-firing port means that the speaker can be placed either close to, or physically on to a wall without effecting the bass response of the unit. The back of the 686 features an already integrated bracket to make wall-mounting the speaker an easy task.
The 686 has been reduced in size to exist in a much slimmer and more compact cabinet. As with all 600 S2 series speakers, the 686 utilises a specialised decoupled, double dome aluminium tweeter to offer a dramatically superior high-frequency response.
