Meridian Updates the 7200 Speaker
Meridian pioneered the integration of digital crossovers and D/A converters in a powered loudspeaker and the first room I visited at the 2013 CES featured the DSP7200 speaker ($38,000/pair). The has anew tweeter, said to be smoother and more open-sounding than the HF units used in earlier speakers, but perhaps more importantly, the 7200's crossover now compensates for the low-frequency group delay associated with the high-order alignment. This is difficult to do, as it conventionally demands a very long digital, computationally intense filter. However, Meridian's engineering team came up with a solution that only adds around 40 milliseconds of latency. While this might make video synchronization tricky, the added clarity at low frequencies was impressively audible. Bass started and stopped as it should, with none of the feeling of the lows being detached from the upper ranges that is typical of high-order woofer alignments.
Kal Rubinson has been promised a pair of DSP7200s for review.
