It's great your wife is interested, and also proud of you!
Could you post your EQ curve please if it's available, the 3012HO l find very interesting, and almost prohibitively expensive here. One day I'll get my hands on one.. 🤞

The Lavoce WAN 123.00 is very close to the 3012HO and may be less expensive in some locales. The WAF 122.50 is considerably less expensive and also works quite well, it's just heavier.

Excellent, thanks for the heads up! They're on the radar :)

Got the Jacks installed to the home they'll spend most of their time in. I built a couple corner shelves for the Jacks to sit on and they are quite strong. I'm confident that I could sit on the shelves without issue or risk.

The Jacks perform better than I could have hoped. Bass response is amazing! Seriously sounds like there's subs up there with them. I'm very very happy with how these turned out and so far, others are very happy too!

Thank you Bill for your awesome designs!

That came out amazing. That dance hall is going from mediocre to premium sound right quick. Well done!

Guessing the subs are still more than adequate with the "underpowered" amp.

Too cool.

Thank you Seth! I'm quite happy with how it all turned out. In the last image up there you can see the speaker that the Jacks are replacing in the bottom left corner. Here's a closeup:

That's right where they use it too. On the floor. It's a great speaker (I've got one at home and it slams for its size), but it doesn't work well for an environment like this. Especially firing at everyone's ankles.

I'm sure that the T39s are barely registering on that amp LOL. I accidentally cranked them when I was installing them (had the channel up WAAAAAAAAY too high on the board) and O.M.G. Yeah, that amp isn't even trying.
