Trying a GoPro stereo audio/video recording of the AGN II's with some classical music for a listening session.  This is a Telarc recording with the info in the video description.

YouTube says it will not play everywhere, but will see what happens.

Watch your volume!

Nick,
Thanks! 

This should be very revealing of the differences for anyone that has not heard all styles of crossovers on one speaker. 

The upgraded passive parts are also better matched channel to channel compared to the original crossover.   

Working on a demo for CAF2024 room 702. 

Had feedback that folks want to hear what the dspNexus 2x8 can do for normal box speakers, so have a plan to retrofit a 2-way speaker I will call the M1 with an ABC Switch to allow the room to hear the difference between the original passive crossover, upgraded passive crossover and the dspNexus 2x8.  This was a production speaker that is an 8in acoustic suspension woofer and sealed tweeter. 

Been working on the switching system to go between the 3 crossovers and using relays with a RPi5 as a controller driving power MOSFET's driving the12VDC  relays.  All the wiring and connectors are the same for all 3 channels. 

The RPi5 control system works, so now to try and house the system for use.  To prototype, just using cardboard boxes big enough to hold the parts. 

There will be one box behind each speaker with a separate control box with keyboard and monitor for switching control.  The Neutrik 4-pole connectors are the drive signals to the replays with protection diodes.

Here are the relay boxes with parts just being test fit before cutting holes and installation.

The XLR splitters are now installed for the 4 servo amps. 

Oh yeah!!! 

It now has the effortless dynamics like live music.  Simple mic recordings are in the room with a big sound stage.

Now I have to get the room acoustics treatments again to fix the few things I am hearing that are off. 

Fun stuff!

Email me dimensions and pictures 

Dave,
The 12-12in subs are old.  I checked and they are where the T-S parameters are supposed to be.

The 6 new ones I got need a lot of run-in time to settle down.

Working the planars now for a few hours and that seems about all they need from the past use.

I have to use XLR splitters to run the 4 servo amps from 2 DAC channels.  Got those to use and will have them all working.  With just two 3x12's it was fun!

I have NO doubt.
