Rich,

I can almost feel your excitement as this progresses! I have dreamed of projects like this (okay, a lot smaller projects, but still). Someday....

Thanks for posting this! :thumb:

Rich,
Those are the 16 modified LM3875TF Gainclone amps with balanced inputs and DC coupled inputs and outputs.  Designed specifically for the BG drivers in the speakers.

Will be wiring them up later today.  Then see what happens.

mresseguie,
You are most welcome.  Hope it inspires you to some DIY.  It really is a lot of fun to build things.

Speaker cables labeled and started connecting them to the Neo10's.

Next connect to the amps and try some measurements to see how to adjust the crossover for sub to planar level matching.  Then try Room EQ for overall correction.

Installed 200' of speaker cable on the 16 - Neo10 planars.  Finished that so now on to resistance checks and wiring to amp modules.

It's certainly coming together. How do they sound? Or is there some tweaking left to be done (always tweaking  :roll:)?

Still wiring up the 16 amps to the drivers.  Trying to figure out the best way to setup the amps for wire routing.

Since these are just midrange drivers, the only way to really get full range is with EQ.  That will happen with the measurements hopefully today.

All 16 amp modules are now wired to the Neo10 drivers. 

Next up is to connect the balanced XLR cables to the amp and begin testing the digital crossover.

Final XLR balanced connections from the dspMusik to amp modules are complete.

Tomorrow is power up, measurements and Room EQ.

Sometimes you just need a lot of extension cords.  :thumb:

Parts for 8 - 10' extension cords.

Igor, throw the switch, NO not that switch, the other one!

BUZZ, HUMMMM, WHIRRR, ZAAAPPPPP...  They're alive, THEY'RE ALIVE!   MUAHA MUAHAHAHAHAHAHAHAH!!!

The Megaliths live!  Now on to the measurements.

Had my friends Avoosl and Charlie over for beer brats, beer and help with the wiring and connection of the speaker.  Lots more to do, but stage one is complete with a vengeance!   :thumb:

More measurements and crossover work today.  Will be tweaking it a bit more tomorrow and give them a listen.

Hopefully by then USPS will find my next batch of TWL HAL AC cables!   :(
