To summarize it, he liked it
Actually it was a rave review.
A couple of things caught my attention:
1) "There are 12 decoded channels with four additional outputs that can be
assigned to additional subwoofers, bi-amping
(emphasis mine), additional height channels, or
front width channels supported by some post-processing audio options."
From the MP-50 manual:
For the front speakers, it is possible to select an option to use bi-amping, in which the system will route a copy of the signal for the left and right front speakers to a pair of the AUX outputs.
This signal is an exact copy of the existing signal for the front speakers. If the front speakers have been given a size with a cutoff frequency, that high pass filter is applied to these outputs
as well.This means it is possible to use bi-amping for speakers and still have bass management redirect the bass to a subwoofer instead."
I don't get why Lyngdorf mentions the copied HP filter, as it's for the woofer/sub XO, and would be rendered irrelevant for the tweeter channels.
Anyway, it would be awesome if Lyngdorf really means true biamping, i.e. active XO's, and not just some form of biwiring.
It seems like it would be straightforward, by using the Voicing function to apply a LP filter to a front channel to drive the woofer, and a HP filter to its copy to drive the tweeter (or vice versa).
Are there any gotcha's here, like limits to the freq range to which the HP/LP filters can be applies (I'd need about 1800 Hz)?
Also RP would have to know to simultaneously drive both woofer and tweeter channels at once when calibrating.
Has anyone tried this, or know if it's truly supported?
2) "Another interesting effect happened when changing the three front loudspeakers from Hsu Research CCB-8s to Vandersteen 3A Signatures and VCC-5 center channel....But RoomPerfect made the different loudspeakers sound freakishly similar. Not identical, but very close tonal matches for each other."
This is puzzling given Lyngdorf's avowal that the intent of RP is to maintain the character of your speakers.
