SW300 in-wall subwoofer expands new 300 Series line

As part of the launch of its new 300 Series of installation loudspeakers, Meridian Audio Limited has announced the forthcoming introduction of an in-wall subwoofer to augment the line. In addition to complete integration with a Meridian audio system, the SW300 In-Wall Subwoofer can, like the 300 Series of installation loudspeakers as a whole, be employed with third-party systems.

The SW300 consists of two separate parts: the in-wall unit itself and a rack-mount S300A Active Subwoofer Controller that will drive up to two in-wall units. The in-wall unit is the same size as the company’s 320 in-wall: with a back-box that is under a foot wide and under 4in deep, it stands just under 2ft tall. Inside the rigid, aluminum and marine-ply enclosure, specially designed to minimize cavity and wall resonances, are mounted a powerful 8 inch bass driver and an 8 inch Auxiliary Bass Radiator. A single cable pair feeds the unit from the rack-mounted Active Subwoofer Controller. Overall system in-room response is quoted as 20–160Hz.

The controller includes a conservatively rated linear power supply with a true toroidal transformer, alongside two powerful amplifiers each capable of delivering 180W into 4 Ohm Impedance. The controller includes balanced analog inputs on XLRs along with mono, left and right inputs for each amplifier. There is also an S/PDIF digital input carrying two input channels, either or both of which can be picked up by either amplifier. Controls per channel include gain, lowpass filter frequency (40–150Hz plus defeat), digital input channel selection (1, 2 or 1+2), absolute phase and reset. The unit also includes Meridian Comms control interconnection with other Meridian products via DIN and BNC connectors.

The SW300 In-Wall Subwoofer system will be available later in the year. The Manufacturer Suggested Retail Price has yet to be announced.
