Speakers are built! I wanted to raise the tweeters closer to ear level so I added legs in sort of a mid-century style. They sound good, but not yet great. The dynamics and impact that I was looking for are definitely there, and they are far more efficient than my former speakers. Bass is punchy but also slightly muddy, and some vocals (especially female) don't sound as clear as I would like. Listening fatigue comes on pretty quickly.

EDIT: While writing this, I had the amp cranked up probably 82+ dB range. Turned it down more in the 68-75 dB range, and they sound noticeably cleaner. Amp is only 50 WPC but it should only be pushing a few watts at these SPLs.

Not visible in the photos is a 1 1/4" x 3/4" MDF rib glued to the top, and a 6"x12" MDF pad glued to the bottom as a platform for the crossover. I used poly batting around the tweeter section and after first audition I also added (4) 12"x12" acoustic foam tiles around each woofer. This made a clear improvement but maybe it needs more damping?

Of course I need to do some experimentation with placement in the room. The ceiling has foam acoustic tiles and the floor has a thick jute rug.
