Baffle width.

marchel · 9th February 2010, 02:05 PM

HI,

I will be replacing the satelite speaker on my desktop PC speaker, With home made ones.

I will be using one 3" fullrange driver for each channel in an open baffle configuration, Question is , What would be the right baffle width for it to operate down to about 300hz properly ?

Thank you.

If you are looking for a baffle width that has no baffle step down to 300hz, the answer is, "much wider than you can put on a desktop." Like 15". But, I assume these things are going to be fairly close to, or sitting directly on, the desk. And maybe close to a wall. That will make for some substantial interaction/reinforcement. You could spend some considerable time simulating it (maybe Edge would be ideal?). I'd probably just build them whatever size looks good and call it a day.

I don't know how well this would work, but if you have them right up against the edge of a flatscreen monitor, that would effectively extend the baffle in that direction. Then maybe the other edge could curve around the side of the desk?

You could always experiment with cardboard.

But in general a 3" driver and the confined space of a desktop are both bad news for open baffle. I do love the OB sound, but for my PC speakers I went for sealed.

Oops, somehow I was just thinking of baffle width, not an OB! How about a U shaped baffle? Make it as wide as you can, and then give it some "wings". For the size you are building, I would absolutely experiment with cardboard.
