Thanks, was a long project with a few changes along the way (as I learned what did and didn't work).
I don't have any photo's of the internal matrix (anymore) and have never seen inside the B&W speakers. I did pinch their idea though as it makes perfect sense and suspect the insides would be similar.
I'll take some pics of the amps later on. They're not painted yet - just white primer. I don't think I've got any pics of the insides though - maybe the input board only. I'm thinking about changing the amps to Hypex so they can be mounted into the base of the speakers. There's room left in the base for amps to go, I just never did it. With the Hypex amps and Power Supplies it would tidy up the wiring a fair bit. Most stereo setups (2 speakers) only have one pair of speaker cables and interconnects (some maybe 2 pairs of speaker cables). For active setups you need one pair of speaker cables and interconnects per speaker - 5 pairs or each in my case.
I like to show it off too so anyone who wants a listen is welcome if they're ever in Napier.
The next generation will have the amps, and DSP in the speaker with wireless connections. All I have to do is figure out how to sync the two speakers. It shouldn't be too difficult... The only unknown is how sensitive the ear is to left/right timing errors - I suspect as long as the difference is under 1us you won't notice. It should be fairly easy to get the two speakers sync'd to under 100ns.
Here's some amps pic's:
Front:
Still only undercoated... The indicators show power, protection, overtemp and clipping. These pre-date the DSP modelling the speakers and amps so clipping cannot occur. Protect can still occur if there's DC present in the output. Overtemp is in case of fan failure. There's 2 internal low speed high-pressure fans that suck air in over the 5 x 1kVA toroidal transformers , 200,000uF caps per channel and then blows up the heatshink. The fans are variable speed based on heatsink temp and you never hear them unless I've been blasting Infected Mushroom for 20 minutes+ and then only slightly between tracks.

Balanced XLR's and 4 Pole Speakon connectors.
