The Meridian architectural loudspeaker lineup gets a pair of in-wall additions-- the DSP640.2 and DSP520.2, the first powered by the Meridian Class-M DSP Engine allowing for high SPLs and strong bass performance.
According to the company, the double precision Aux filter improves resolution on low frequencies, while built-in dynamic bass protection technology maximises bass extension. In addition, the two models integrate "DYNAMIC" high-resolution amplifiers, with an electrically screened, potted and optimised high mass toroidal transformer promising the least possible mechanical noise. Post filter feedback delivers lower output noise and improved total harmonic distortion (THD), allowing for even the smallest details to be heard.
