Hi Beto,

Here are a few examples from simpliest to more complex:

PI One

PI Three

JBL Cabinet

Garden Sub
http://pg.photos.yahoo.com/ph/lowgc/album?.dir=e3bc&.src=ph&store=&prodid=&.done=http%3a//pg.photos.yahoo.com/ph/lowgc/my_photos

The last one's an interesting build. An 1,150 cubic ft cabinet cleverly disguised as a shed. 3/4" panel braced every 16" with 2x4's, veneered with 1" thick bevelled pine siding. A peak-shaped top to minimize standing waves and isolated off the ground with six cinder blocks to reduce resonance. Roofing felt and asphalt shingles on top further dampens out vibrations. Porting is done through a ridge-top and soffit vents.

Gar.

Hi Gar,
Thank you very much, you have made a wonderful job and actually help me a lot. The following was my doubts before I read your post.
The first thing, and the most important,(and was my fundamental doubt) that I can see is about the vertex union. You use wooden plugs & glue and is similar to my original idea, but I have never seen an speaker job. An alternative is with special bolts (the ones with a continius diameter; I don't know its name in english, with wooden plugs as a cover), but I think your way is the purist. I supose that you don't use nails or bolts.
The second thing is about bracing, since I will use plywood and PI4 are small, I don't need to use too much of them, just a pair above and below the woofer.I will use 3/4" or 7/8" ("marine" was here the name for the one who has a treatment against moisture )
The third is about how to insert the woofer in the front panel, in other words, the diminution in the front panel thickness to fit the external ring not in the same front plane.
Thank you again.
Regards,
Beto
