DIY speaker bracing...

[sumday]

I picked up a rather tatty pair of Celestion DL6 from a neighbours garage earlier this summer and after copious cleaning and fettling they look and sound (for no money) fine....in a second system sort of way.

BUT the cheap chipboard cabs sing along with the drivers at almost no volume.
I've bodged a few old speakers in the past...usually big brutish cabs with bracing already in place.

Can anyone suggest a cheap way to stop these enclosures joining in?
I was thinking automotive damping pads perhaps, or short lengths of erm..brush stave internally glued.

If you have room to get into and work inside the cabinet, you could try and put vertical and Horizontal braces inside, cut from plywood off cuts, these should be easy enough to source. The cabinet will benefit with the plywood having 75mm diameter holes drilled into it, to enable free air movement. If the braces would be required to be cut into half to shuffle them in, I am not sure if this will diminish the improvements on offer.

Bracing will be more effective than damping pads on their own, but bracing plus damping pads could be effective.

Cheap? try -if you have some - using Cork tiles inside.

If you're rather MORE way-out, use lots of wine corks!

My Leak Sandwiches have a bolt that fixes into the back of the driver to make it rigid-er.
Plus thick interior padding.

You could use a wooden broom handle cut to size for bracing, works a treat. Remember though, measure twice cut once :)

Used this stuff in a number of speakers.

When restricted by the driver hole entry I've found triangular pieces of mdf as big as you can fit through the hole placed around the enclosure (think bulkheads in ships) are very effective and dead easy to fit-obviously add to taste and with an eye on the volume....
