With the amazing amount of failure floating around the first DT BP10B rebuild I decided with 180 days in shop class to partake in building another set. As you can see - I brought them home and put them together - building something in that classroom is next to impossible. I'm surprising the cuts are as good as they are...

This rebuild is heavily braced unlike the first one - This one is much better I think.

I attached some pictures of what it is I am building (concepts)...

The aesthetics are still kind of up in the air - but I plan on doing a textured black finish (roll on truck bed liner, none of that spray) - with LSi like (not the same) walnut side panels split into 3 sections. Also will have a top cap and a "X Stabilizer" on the bottom that the spikes will attach to...

And yes, the bracing is pretty freakin solid - tons of glue, tons of screws...

It's kinda like a beatch.
Good work MX!

Thanks Max,
Bracing an enclosure is an interesting experience. Interesting in the sense that even the smallest amount of unbraced area allows a resonance. The space between that large brace and the strip boxes... it has a different, higher resonance than the lower and upper portion of the cabinet. VERY weird. However, I have to put the crossover SOMEWHERE

Testing Part 2...

You should tell your shop teacher to either get new blades or have them sharpened. Either that or you are pushing the material through the saw too fast. From what I can tell, it looks like alot of burned edges on those braces.

Burned edges come from too things. Cutting too fast or a dull blade. Using the improper blade will do it too. your shop teacher needs to take care of that, it is extremely dangerou using dull blades. They can kick and grab the material you are cutting and it will injure you or someone else in the class.

It you are getting serious about this stuff, perhaps one should be asking mom and pop for shop tools and some work space in the garage or something for Christmas?

Could be a mixture of both...

Considering these blades are used 180 days a year... 7+ hours a day... - lots of wear and tear, although he keeps good track of the materials with the budget we do have...

I also went pretty fast with the braces as far as ripping... mainly because I had other things to do and on a width stand point they really didnt matter - and I had to cut alot... there is over 460" of bracing between the two speakers... and thats not counting those two large center braces...

(As you can tell, there is not one burn mark on the MDF...and I used the same table saw...) I was going for some pretty precise cuts there...

I really want to build up a shop in the garage... but a car is standing between me and it...

I definitely plan to save up for a table saw within the next 2 years... then probally will pick up a radial arm saw... then possibly a band saw - three tools I definitely need.

But for now, I have a router, drill, jigsaw, and palm sander - which is quite a bit that allows me to do alot at home. The school has some pretty good radial arm saws and table saws - as well as good band saws...

I have alot of space in the garage though - so its really cool, I can back out the car and have over 20 feet in depth, 25 or so in width... tons of room...
