8" Audax Aerogel woofer
Focal 1" inverted titanium dome
3/4" MDF 1/4" Birch ply
5-way binding posts
Is the speaker intended to stand on the floor, or do you use it on a stand?
They probably should be placed on a stand, but they are really heavy (>40 lb ea). Anyway, they are currently in my parents place, not mine, so I don't really care. Sadly, the Aerogel woofers, which sound great, are practically impossible to find nowadays. Actually, I guess both Audax and Focal stopped selling OEM drivers, which is a shame for DIYers.
