Preparing for first DIY "project"

454Casull · 19th July 2006, 12:51 AM

I'm going to build open-baffle versions of Zaph's "best 3" speaker" - basically, the easiest speaker to build ever. Although I do want to make sure of something: is the notch filter the 3-component part in this circuit?

And I don't need the BSC, right?

Also, what power rating should the resistor(s) be?

Forgot to mention that these would be replacing the crap satellites that came with my PC speaker set. I doubt the drivers would be getting any more than 10W a piece, if that.

Hi,

You don't need the BSC if your baffle is big enough.
If its not big enough you get baffle roll-off, not step.
The notch filter is the 3 component part .
3w wirewound should be fine.
