Close to the Edge

PeteMcK · 17th May 2005, 08:42 PM

Thanks to that amazing piece of software 'The Edge' I've made a simple Q&D OB. The Edge had the driver placed closed to one edge of the baffle, & although I was sceptical about this I tried it, and it worked amazingly well.
Now I want to know why I can't make the baffle like this?:

Irregular polar response? Hard to eq. roll off?

Mechanically unstable?

sounded more forward in lower mids than my Peerless 850488's (in 4L boxes), but about the same amount of low end:

Immediately noticed an 'enclosed' feeling to the sound, not as good as the flat baffle (need to do more listening). Ameliorated a little by turning the corner to the front. Tried swapping L & R sides - immediately noticed an improvement in low end; so my time wasn't wasted. So for asymmetrical baffles, the long side should be on the inside?

What driver is that? 6x9?

Hi Dave,

Its a 165x65 cm unit out of an old Sony tape recorder,
sorry don't have the part # handy, but it sounds good & has a reasonably wide range; I'm planning to add piezo tweeters & 12" woofers when I sort out a good baffle shape (which will probably be an asymmetric pentagon); I'll Damar it as well.

Cheers,
Pete McK

sorry, much smaller.

Actually, I do have a pair of larger oval units of about the same vintage, Magnavox, a defunct Aussie brand I think. These are about 10" x 4", but don't have very good lows & squawky highs due to their whizzer. I've Damared the cones, and I'm going to try some car underseal on the accordion surround to see what change that makes (+ damp the whizzer or remove it).
