Or get a TDA8932 monoblock for $3 to $4 ea. These totally sound better than Lepai 2020. The bass is very punchy.

Hmm, very nice.
Must get a few and give them a try! Can even run off a 12v battery if need be.
I'd imagine 10-15W to be sufficient for these though? They're pretty efficient already.
Any experience on if this (stereo, bluetooth) version is any good?

Yes this looks like a far better solution. One again my choices were based on what I had laying around (slow basement cleaning?) And I had the heatsinks, transformer and burned out k8060 from sins almost 20 years ago..
What other class d chips are good sounding? Ta2020 <12w,TDA8932 <35w, any other that's worth mentioning?
I have some LJM L15D modules and they're really good, however overkill for the Mini Karlsonators.
150W @ 8ohm
350W @ 4ohm
Perhaps for another project or a subwoofer to fill in the lows and compliment the mini K's
Look for TDA7498. They sound great too.
TPA3116 is very good but has turn on thump. I like bass in 8932 best.

beautiful amp build ! - elegant K'nators with proper K-tube implementation !
I'd like a potent and smooth "K10" - or maybe a K'nator 10 - -any suggestions? - it has to be punchy and take 200W - -tempted to get 10fw64 B&C although qts is pretty low
this is a nice looking 10 for the sale price:

It's two Velleman k8060 Velleman Kits K8060: DISCRETE POWER AMPLIFIER 200 W – Velleman – Wholesaler and developer of electronics
The case I designed and 3d printed just like the k-tubes.
Thank you for the nice words xrk and freddi, it's thanks to you it's built the way it is!
I have a couple of that 7498 and like them. I love having some sort of volume control. The gain switches are nice.
Opinion on front vs rear mounting of drivers
Does anyone have an opinion on front vs rear mounting of the drivers? I use 9mm ply.
Front mounting seems to me a better flat 'connection' to the baffle (speaker cone is not sunk in a 9mm deep hole), but I also recognize a small rear output in that case. Rear mounting gives the cone a better output backwards.
Opinions?

I'd say front mounting, easier access as well.
You could perhaps chamfer the rear if that's your concern?
I had a fit with speaker mounting. I thought the same things. I ended up making a frame like a picture frame out of the thicker stock and gluing that in place and then putting the speakers on thin material and screwing that whole plate over top. Outlined the edges in foam before I screwed it down. Rear mounting means you can't get the speakers out very easily. But it sure looks nice in your picture.
Hey foam core conquistadors, what do you think of xps board as a construction material ? At the outset , im not a larp. I had this idea while researching panels for a dml loudspeaker. If you're familiar , some are made using pink 6mm xps foam like this Prowarm 6mm XP-Pro Insulation Board (1200mm X 600mm): Amazon.co.uk: DIY & Tools
Im considering this over ply for projects including karlsonators and horns as im building them in my listening room and my neighbours might appreciate a lack of circular saws etc running. They can be cut accurately using this tool YouTube
Here's where i need to draw on your knowledge people . Am i right in thinking to act effectively as a wave guide the horn should be reflective rather than damping sound waves ? ( foam being slightly spongy rather than hard ) ? If so this foam can be painted with resin to leave a hard plastic finish. Those larp people ( so i believe ) make rock hard fake armour this way? What do you think folks ?

XPS works great as speaker material. Examples by myself and Perceval.

I have not made a Karlsonator with one but think it will work fine.
