Beovox 2500 cubes

9 replies

I have just acquired a pair of Beovox 2500 cube tweeter units. Several of the perforated aluminium frets have become detached from the units and have paint chips. Just one edge of the painted hardwood cube sound box needs a bit of restoration on one unit.

All the frets have slight depressions and will need working on a flat surface to get them back into shape, which leads to my first question. Were they completely flat when manufactured, or were they slightly convex?

Does anyone have recommendations for the best paint to use on the frets when restoring?

I am going to try to restore the paint on the hardwood cube leaving as much original paint as possible, although in the last resort I may spray the whole of one side. Has anyone undertaken restoration of the paint on the hardwood cube?

Any advice appreciated.

Graham

Thanks Leslie.

Did you need to correct or reshape those slight convex shapes using a former?

Also, where the cables enter the bottom of the stem above the stand there is a loose plastic sliding thing, looking a bit like a plug and shown in your pictures. One of my speakers has that plug, but the other one is missing having split and fallen off. I am not sure what useful purpose they serve, but are they available anywhere?

Am I right in thinking that the frets have a light grey undercoat under the matt black finish? I can see some raw shiny aluminium chips, what looks like undercoat, and also white flecks of paint from when some previous owner has been emulsioning his ceiling without protecting the speakers!

I think the plastic plug is ment for hanging the cubes on the ceiling where you first have to remove to round base?

Will check if I have one left for you...

Could be, I'm not sure

Good luck Graham and have fun with the refurbπŸ™‚

I've removed all the frets. After inspection it looks as if most have been distorted from a mild convex shape to a concave shape, presumably caused by people picking up the cubes by stretching a hand over the cube instead of lifting by the stand. Some have got a couple of dimples from touching the screw heads holding the tweeters. All fixable, and most paint chips, being near the fret rims, are probably restorable with touch-in paint rather than respraying the whole frets.

These cubes came with the original box and polystyrene inserts. I suspect that I need to keep the box to maximise future value. I'm not sure whether a full electronics restoration is justified as I suspect most people keep them for display (and I don't have space for beovox 5000's)!

Hi Leslie

Your cubes look fantastic, I have been lucky to find a pair with all there covers but I think they need full restoration, would you be able to do this.

Marc

Sure, why not?

That's great news whats the cost and when can I get them sent to you.

Leslie, are you still active ? 

Hi , Leslie is gone a long time. He is possibly available on FB ? He did some great repairs.
