this is @sphinxvc 's place btw, not mine. I just storing/set up there for the time being..
Are those the Voxativs?

Dang. Central Mass even, so within driving distance. Congrats!
Nice! What's driving it? That tube amp or the M-22? You prefer MWW or WMW?
MWW was better
WMW - too short, missing some details from voxativs - me and sphinx thought. Bass is also better with MWW for some reason.
Heard at guy's place with custom 300b amp and 4P1L(?) pre-amp - huge ass 3d soundstage, intoxicating mid, badass bass. Probably max performance.
Drove with M22, F3 + saga at sphinx's place - still pretty damn good but not as good as above. Maybe need tubey pre-amp for 3D soundstage? dunno. $1200 power cable is probably the answer.
Interesting! MTM is supposed to be good for time alignment, however that might be more an issue for high frequencies and the TM section is encompassed in the Voxativ.
I probably need to tilt back in MTM configuration a bit. Probably some information was hitting the floor before reaching the ears cause voxativ's are co-axial(? not sure).
MTM sounded plain stupid, uninvolving, muted. Predictable given top-end is beaming at crotch level. What was PAP thinking? TMM is better, but still higher than ears in the typical listening position. Why would MTM help time alignment? Acoustical centers don't change forwards/backwards, does upwards/downwards matter too?
Congrats!! PAPs are truly magnificent speakers. I kept mine in MTM and considered lifting the whole lot on platforms. Sitting upright stifles the widebander sound. Now I listen on a sofa recliner at ear level of the Vox driver and it works really well. TMM is the other option I did not try or go nuts and get a PAP quintet arrangement! lol
Time alignment might be the wrong term, better to say acoustic lobing. With traditional TM speakers you get the acoustic lobe pointing downward. This can be resolved by tilting the speakers back or using a stepped baffle to time align the drivers. MTM can also resolve the issue of lobing due to vertical symmetry, however this doesn't mean it's time aligned. Which is where I got confused.
Lobing factoring into time alignment doesn't seem unimaginable to me but I'm not sure either. It's possible they're meant to be heard from further away which might help with the super low MTM dispersion? I think my position is roughly 10 feet away. I'll measure tomorrow to be sure.
Holy moly ... that is a bargain used price! Stock full of upgrades too. Been thinking about upgrading the crossover parts lately. Interested in the cap and coil upgrades you got.
