Want to build small subwoofer

[c3ham]

hi

no i didnt use a flush trim bit just sanded it with an orbital sander the joints where nearly perfect anyway Is it a feedback destroyer i would need to use to tame the curve paul?

[paulspencer]

You could use that, yes. It's a cheap simple option. Another is Ultracurve (more expensive but also will eq mains).

would there be any point in stuffing my box with accoustic wadding?

thanks guys

Depending on what you use and how tight you pack it, you might notice a small difference.

thanks for the reply richie i bought this gear http://cpc.farnell.com/jsp/endecaSea...sp?sku=LS00385 do i just add it to each of the inside faces or do i stuff the whole box with it ? and what exactly does it improve

[paulspencer]

Stuffing lowers box Q by increasing the apparent box volume. Stuffing should fill the entire box, otherwise what you have is lining which will have a different effect - merely to absorb lower midrange frequencies, say above 100 Hz.

That stuff is BAF wadding, I use it myself. If you fill the box but don't allow it to compress much it should increase apparant box volume by a small percentage, and if you had any midrange honks they will probably go away unless they are cone modes.
