Here is a little photo essay of my latest build. An MTM with two Peerless HDS-P830869 woofers and a DX25BG60-04 tweeter. I wasn't sure if it was going to build an MTM or 2.5 TMM, I decided on an MTM.

Not a bad looking woofer, that Peerless 830869. Cheap too! 30L of reflex per driver according to data, 23X7cm tube.

Of course, I want to see the crossover. This is a nice idea. Must be series wired bass, mustn't it? Otherwise the tweeter is going to get pushed too hard.

Anyone can build a box. Er, except me... I stick to soldering. 😀

Can I ask the inevitable question about wood movement?

Wood only moves width wise, not length wise (or very close to zero)

Sides/top/bottom are fine, grain all the same direction. The glued in back is veneered ply and is also not going to move.

The problem is a solid front baffle. I did it sort of the way I attach table tops. There is room for the bolts to move. That is why it is gasketed and bolted, not glued. The threaded inserts the bolts go into are the in bottom half of the board they are in which means there is lots of clearance for the bolt (the hole for the insert is much bigger than the bolt, I hope that makes sense).

The freq response is the left and the right, hard to put the mic at the exact same distance when measuring the separately.

Great job. Very Nice woodwork and well thought out.

It is the wadkin band saw that caught my eye.

Enjoy,
Evan

I bought the bandsaw as a wreck for $200 from a window company and put another $1000 into it for a new motor, starter, vulcanizing new tires onto the rims, guides, bearings, paint, etc. Worth it in the end, $1200 (CDN) for a 20" 3hp bandsaw with 17" of resaw. 🙂
