Dang, Rich! You're a 12-year-old kid again (but with a beard). What a terrific project!

That is the plan.  Do what I want and see what happens.

Acquired the correct balanced Y XLR splitter cables for the prototype setup with the 8 channel dspMusikLCD and getting the amps connected.  It was easy with the ChipAmps as I had the XLR Y's built in.

Amp connections continue and wire paths straightened to make easy cable runs to the dspMusikLCD and line arrays.

After 2 days of work with my friend Avoosl, the 10 Parasound A23 amps are installed and making great music. There is no strain ever on any volume level for replay. The system is not even done and it sounds really good!

Here are some first pictures of the system after removing the ChipAmps and installing the A23's.

Thanks go to Avoosl and Richard Schram at Parasound who have helped greatly to get this speaker system to the next stage of existence.

If anyone does not believe DSP crossovers can sound better than a great passive version, they should hear these speakers. That can be arranged!

Chuck,
For some statistics, the ribbon tweeters have 400 watts rms, Class A/B, the midranges have 1200 watts rms, Class A/B and the servo subs have 800 watts rms, Class D per side!  That is a total of 4800 watts rms of power with headroom that never gets reached.  That is the equivalent of 6.4 horsepower of drive.  All being driven by the dspMusikLCD as the entire front end with the MS-3 as the Music Server.  The ADC modules are very clean indeed!

Having a lot of fun listening to this!

Rich - those speakers are really starting to look scary - reminds me of an old sci-fi movie 'Kronos.'

The Megaliths 16 channel dspMusikLCD crossover design is ready for testing.  The system arrives next Sunday for measurements and listening trials to begin.

The excitement builds!!!

You should bring them to one of the audio shows.  I'm thinking RMAF next year would be a good choice :P

Most likely if I do it will be Capital Audio Fest for 2018.  Waiting on word of large room availability. 

I can drive there in a few hours.

The 16 channel dspMusikLCD with the first revision The Megaliths crossover is up and running! 

Need to make more measurements and try the room correction with Foobar2000 with the new crossover.

This is getting better all the time!!! :)

Who let the housekeeper in there!?!  :icon_lol:   Did they vacuum up all those chip amps?

Looks nice Rich, if not a bit intimidating!  :o

Is it a 3 way?
