Do these braces need improvement

andy2 · 8th May 2005, 11:18 PM

Do you think I need extra reinforcement to these braces? I hate to do any drastic changes but would rather try to get it right than having to redo them. I've never done anything this big though.

The internal dimension of the base module is 660mm x 210mm x 380mm.

I'm sure you'll have plenty of volunteers but I'm not going to sit there while a 400K picture loads.

you should be ok on bracing, but I would suggest some acoustic stuffing at least on the enclosure walls to dampen reflections back to the cone

Plenty of bracing there.

The only thing I'd redo and I'm picky, would be the center brace on the bass cabinet. All of the two braces that connect front to back are only joined by a small amount of MDF because of the circle cuts in the adjoining brace.

It will be fine without but I'd redo the top to bottom brace with squares inside of circles to allow full contact on the other braces - OTT maybe but if a job is worth doing its worth doing right.

Those are 3/4 mdf. The front baffle is two pieces glued together.

I understand what you mean but I already ran out of wood and to do that I need to purchase another 4 x 8' panel. What I'll do is glue a small piece of wood at the opening in between those braces (that you mention) so that they are pushed against each other which would give them extra strength. Not perfect but a little bit better.

Is the centre brace in the centre? -- or is it offset from the middle of the panel?
