     I have set up a 16 channel system with 7 floor Edgar horns, six inexpensive height, and one overhead speaker (all under $150 each) and one subwoofer channel, all controlled by a Trinnov Altitude 16 pre-pro, which is a computer with software which can do speaker and room frequency, amplitude and timing correction, plus channel decoding. In addition, it can remove hall information in a two or multichannel channel recording and send that information to the proper surround channel. All are using Behringer active crossovers and relatively inexpensive ($100 to $400 per channnel the total of 31  amplifier channels. Each channel has less than +/- 2 db inter and intraspeaker amplitude variation and less than 0.1 seconds time alignment variation at the primary listening position. Using Auro 3D for multi channel and Auromatic decoding for two channel recordings, I have now what I would consider to be the best recreation of a concert hall experience I’ve ever heard with a large percentage of recordings I,ve kept over the years.



Thanks for this information Bill.  Were the 16 channels (I counted 15 in your description) an all-at-once installation or have you worked up to that many channels in steps with the Trinnov 16?  Say 4 channel then 8 then 15 or something like that.  Would be interesting to gauge incremental changes in the "effects".

I can see why Romy is working at this problem the way he is given his system topology.  I too am reluctant to put all sources through a processor given how much effort has been made to keep unnecessary (DSP etc.) electronics away from Macondo/Melquiades, but if it is possible to only put the surrounds/reverbs through the processor while getting much of the overall soundfield benefits of your Type 6 system above, then perhaps this may be the best solution in this instance.  It seems that in audio to get more here you have to give a little there, and I agree that Macondo/Melquiades is something special for stereo playback, but what would be given away to go Type 6?  Rhetorical, of course.  The only way to really know is lots of time to experiment with more capable processors and loudspeakers in the room.  I wish I knew, this is a really interesting.
