Over on Servo Sub kits thread I posted about helping Michael move about his workshop a pair of GR Research Servo Sub Five 3 x 12” woofers stacks with the servo amp built into the base of the H-frame. Not available to tag along for the long weekend 20+ hours of driving delivery run I implored Michael to take pictures. Here are the results, must say I am blown away.

Woofer closeup frontside after No Rez install. Notice the care taken trimming the No Rez to size.
Now the results in the client's system. The system (of which I am a bit jealous and certainly admire greatly) includes:
- Auralic Aries G2 music streamer
- Auralic Vega G2 DAC
- Auralic Leo GX external clock
- Parasound JC2 preamp
- Parasound JC5 power amp
- Martin Logan Summit X electrostatic speakers
- GR-Research triple Servo controlled Open Baffle H-frames with 12” drivers
- Tidal with cell phone app to play music and control the system

Client's electronics.

Left channel, sub grills off.

Right channel, sub grills off.

Complete system, sub grills on.
My understanding the room is just finishing up construction after long delays, thus the lack of other furnishings and dust barriers taped to the wall. Notwithstanding that the client is thrilled with the sound. He reports what I heard at Mike’s place, that is these subs not only add bass to what the Summit X previously delivers (and they certainly do that) but also the strings, horns, and other details are more clearly audible at much lower volumes than they could listen to before adding the GR servo subs. After Michael left client reported marathon listening sessions into the night then restarting the next morning.
Looks like another happy GR Research + Michael Lundy team customer.
