Price is per single speaker
Meridian has introduced a new in-wall loudspeaker to its architectural loudspeaker line-up, enabling integrators to deliver the authentic, superior audio performance that customers want for their home cinema or media room installations.
Characterized by their high SPL’s and strong bass performance capabilities, the new DSP640.2 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 maximizes bass extension, achieving the finest possible audio outcome.
The first to integrate Meridian’s “DYNAMIC” Hi-Res amplifiers, for renowned audio quality in a wide range of installation applications. Each drive unit is driven by a pair of powerful, high bandwidth, ultra-HD amps for guaranteed performance and complete control, exceeding the Hi-Res audio standard.
The amplifier’s high mass toroidal transformer is electrically screened, potted, and optimized 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. This new feature also provides greater control, accurate detail, and precise spatial resolution.
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 soundbar 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, offering greater flexibility and the best possible performance from all digital sources.
With a mounting depth of just 100mm,the DSP640.2 Loudspeakers are perfect for delivering discrete yet impactful sound in any home cinema or media room application. Their sleek, slim profile and frame system allows for easy installation and precise positioning on almost any type of wall, while the grille can be painted to blend seamlessly into any interior.
