Hi,
I agree that an SE sub would not need a new beryllium tweeter!
LOL ... though my comments should be taken in context ... what I was attempting to portray was that the SE engineering work (in order to support MQA) was mainly to improve the MF and HF performance ... and that these advances were not so relevant transitioning to subs.
But I had thought that the enhanced electronics of the DSP SEs, including a doubling of processing power, were required for the more sophisticated DAC management that is a part of MQA delivery.
Long before MQA was public I was told [by M] that the main purpose for the extra DSP chip was for "advanced tweeter management". It's from this comment and that the DSW supports EBA ... that I feel it DSW
maybe good enough "as is" for MQA.
Hope that helps clarify my educated guess.
It would of course it wold be well received if Meridian commented on the use of DSW subs in a MQA SE DSP system.
Maybe a PP might know the answer?
