The changing roles of hifi equipment mean that audio systems themselves are changing shape. The increasing number of products with
integrated pre-amplifiers mean that many customers are searching for an equally convenient speaker to connect them to. Taking full
advantage of Acoustic Energy’s considerable experience in the field of active speakers, the AE1 Active is designed to deliver this
convenience without trading performance.

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.

Itʼs widely understood that the sound of surround TVs cannot compete with the excitement of a properly designed and equalised home theatre system. But great sound comes at the expense of living space…until now. The wall-hugging RX-FX surround speaker reconciles the problem by providing a convincing, enveloping timbre-consistent surround sound that places you on the edge of your seat and at the heart of the action. Discreet enough to be flush-mounted on side or rear walls, the RX-FX design will blend with the system and your décor so completely youʼll wonder why you ever thought of compromise. Itʼs also immensely flexible sonically, offering direct or diffuse sound effects at the flick of a switch.

The M-1 has been engineered with the same design attributes and ethos as B&Wʼs larger ranges. Perhaps the most striking thing about the M-1 is the weight and strength of its curved aluminium cabinet. This is combined with a strong, glass-loaded ABS front baffle. Together they provide an excellent cabinet: the curved aluminium is stiff and the ABS offers excellent and appropriate damping characteristics.
The M-1ʼs drive units were developed by Bowers & Wilkins specifically for the design. The metal dome tweeter benefits from refinements developed for the new B&W 800 Series and includes Nautilus™ tube loading and neodymium magnets. The glass fibre bass/midrange coneʼs ability to absorb standing waves has been further enhanced by the inclusion of five strategically placed resin filled slots that further minimise distortion.
The result of this detailed cabinet and drive unit engineering has allowed B&Wʼs engineers to borrow another feature from the new 800 Series and utilise the simplest of electronic equalisation in the M-1ʼs crossover. Each of the drive units is fed by only a single, carefully selected component. This approach to crossover design, although painstaking as it relies on optimising all of the physical components in a design, is crucial in achieving its aim of neither adding to nor subtracting from the original signal.
The M-1 is available in three colour options - black, white and silver, each with chromium plated stem and table base.
