Meridian’s architectural loudspeaker line-up has accumulated a new addition with Meridian’s new in-wall loudspeakers.

The new DSP640.2 and DSP520.2 in-wall loudspeakers are the first to be powered by the new Meridian ‘CLASS-M’ DSP engine. The double precision aux filter improves resolution on low frequencies and the built-in dynamic bass protection technology maximises bass extension.

Both models are also the first to integrate Meridian’s ‘DYNAMIC’ hi-res amplifiers. The amplifier’s high mass toroidal transformer is electrically screened, potted and optimised for the lowest possible mechanical noise, while post filter feedback delivers lower output noise and improved total harmonic distortion (THD), allowing even the smallest details to be heard.

The new DSP640.2 in-wall loudspeaker features eight power amplifiers delivering 100W per drive unit and L + R mode for the ultimate, high-power sound bar applications. It’s capable of delivering over 105dB over 4m, providing full range sound with bass extension down to 40Hz, together with Meridian’s on-board Enhanced Bass Alignment that aligns high, mid and upper bass frequencies with the low bass for added clarity. Meridian’s proprietary centre elevation technology raises the perceived image location from an under-screen loudspeaker so that it appears to come from the centre of the screen, resulting in lifelike and spacious sound.

With a range of other enhancement technologies including FIFO buffering, DSP upsampling, apodising filters and MHR (Meridian High Resolution) built-in, the DSP640.2 can be used as a full-range loudspeaker with no need for an additional subwoofer.

The DSP520.2 in-wall loudspeaker boasts an all-new quad-amp DSP design with four powerful amplifiers delivering 100W per drive unit. L+R mode technology ensure the true reproduction of all the audio present in a stereo recording when a single loudspeaker is used on its own, while delivering bass extension down to 50Hz for full range sound. The DSP520.2 features 1 x 140mm long throw bass driver and 1 x 85mm wide-range drivers for full-frequency response, maximum dispersion and wide listening area. It also comes equipped with the latest on-board Meridian technologies including centre elevation.
