The custom modified HX300-8OB servo amps are here and now in their boxes to get wired to the servo subs.
Using the Neutrik 4-pole Speakon connectors on the cabinets and wiring harness for simple connections.
Wiring the cable harness is ongoing as the parts arrived today to complete the wiring.
The 4x8in OB cabinets are to be finished this week and delivered.
Getting closer!

The two open baffle servo sub stacks are complete and making music!
Now for some new measurements with REW to integrate the subs and planars.

I get the idea that you either go big or don't go at all.

Is there any other way?
So, Rich, when's the meetup

Roscoe,
If you come to CAF2023 at the Hilton, the system will be in room 708. I will be running Qobuz for music playback for the show, but can switch to Foobar2000 for file replay.

These are small.
The two new 6x12's are being built to replace the originals. Then two 3x12's in the rear of the room with the left over cabinets that were not destroyed by water. Now that will be big!

Built a phono cartridge cable RCA to XLR interface box to drive the RIAA Phono capability in the dspNexus 2x8. It is a fully balanced phono interface to the coils. Setup with 47K Ohm resistance load and nominal capacitor for the Shure cartridge in the tonearm.
I put in a few different grounding modes, so testing it with the Oracle Delphi MKI and Linn Sondek LP12 should be interesting.
