I was trying to find my notes before I attached that sketch, but I just found them…
The subs are supposed to be tuned at 31 Hz, 37 Hz, and 42 Hz. It states in their description they have separate ported enclosures, so I don’t think the angled braces are window framed, I think their solid (at least that’s how I interpret that).
Overall outside dimensions are 40.5″h x 8″w x 13.5″d and they weigh about 57 lbs each. 5-way binding posts, easy enough, SoundMatch 3-way crossover (not sure what that is, maybe a brand?).
The top Mid has a sealed enclosure w/ angled back (brace).
The tweeter and top sub share the space & the top crossover: X-over includes (8) components – (2) San Pass Resistors, (2) Electrolitic Caps, (2) Iron Core Inductors, (1) Air Core Inductor & (1) Poly Cap
Middle sub: shares space with the bass X-over with (3) components to this board: (2) Iron Core Inductors and 1 electrolitic cap.
The above info came from a YouTube Tear-Down of the Pinnacle Speaker.
