Regarding the blocks they should be either screwed or clamped while the adhesive sets. That forces the adhesive to expand into the pores of the wood for a better bond. Without pressure on the blocks the expanding adhesive can push the blocks away from the baffle and the bond won't be as good. It's n...

For some interesting dialog watch 'Deadloch'. I'm usually OK with Oz/Tasmanian/Kiwi accents, but the dark haired lead character, Madeleine Sami, is almost totally intelligible. Even worse than a rural Scotsman.

Klipsch has been overstating sensitivity for decades; I'm sure that Paul is spinning in his grave while muttering 'bullshit'. Since the SLA has over twice the driver count it will be at least 6dB more sensitive, while the nine tweeters will bitch slap the single tweeter of the Kilpsch.

It's not supposed to be linear, it's supposed to be logarithmic. Doubling of volume isn't twice the power, it's ten times the power.

You had no highs, you had no lows...but you've got the lows now.

It's easier to cut the hole with multiple passes, going through it in one pass bogs the router down and overheats the bit.

The OT12 crossover is 2nd order low pass, 4th order high pass at 2kHz. Never use 2nd order/2nd order, it creates polarity issues.

There are two drivers because the horn is too tall for one to work optimally or keep up with a 600w woofer. They're series wired because they have higher sensitivity than the woofer.

Yes, you'd plane a panel that's too wide but rout or sand the second side to remove any overhang.

Use the smaller side for the initial assembly, make sure all is square, then trim the second side after attaching it to the assembly. A router with a following bit is best for that, though a sander will do in a pinch.

He who dies with the most tools wins. I just used mine for the first time in years, planing a door that was 1/8" too wide for the opening.

If a panel is proud this is what you use to take it down. It's not a tool you'll use very often, but it's invaluable when you need it. https://www.amazon.com/VEVOR-Electric-H ... 15Q1Er8dhZ

You probably won't damage them but they won't work as well as they would with the correct high pass filter.

Looks just a tad bottom heavy.

The high pass for the original compression driver won't work with piezos. They'll function, but the high pass filter isn't doing anything.
