$7 open baffles...

[leadbelly]

Are you suggestting a more elegant name than $7 OBs? (they soon won't be $7 -- phase plugs coming up soon -- i'm guessing i can get a set of FE166/167 plugs to fit)

Splurge a few $$$ more on a can of foam green paint, and you most certainly have built yourself a pair of Gumby's.

Gumby is already taken...

Well, the only other idea I have is "Adobe Dick" from The Flintstones. Might be even more appropriate given you current occupation 🙂

"Adobe Dick" from The Flintstones

Can't remember him... did find mention of a whale-asaurus which i sort of remember.

The wife likes Gumby, and part of the house colour scheme is green (so we have latex paint -- don't know how well it will cover the vinyl finish on the baffles....)

so maybe Gumby Too (or the wife is suggestting "wings")

Did measures on the 1st 10 similar drivers out of the drawer.... tossing outliers the avaerage Fs = 74.3, Qt = 1.41 (using fresh FuzzMeasure beta so results have yet to be manually confirmed).

I'll get to the others so i can view the entire sample... then i need to figure out what the best pair is for the baffle size i have.

Went thru all 21 not already in the baffles today and picked 3 close ones to play with. Fs = 56 Qt = 1.28. This is a set with lower Q & lower Fs than the average.

And the phase plugs don't fit too badly, perhaps a tad small (a layer or 2 of heatshrink might fill them out a bit.

AHHHAAA now i know where this idea came into my head. It was all you Dave. I must have glanced at this post and this fermented in my twisted head.

That is a good page... and the link off to the gallery of vintage japanese drivers -- beauty ...

Way of the OB

Is there any different in bass output between the two OB? I assume the midrange anf high are the same, correct?

They will perform quite diffrently. The narrow one will have at least a couple pronounced resonances based on the length & width of the wings... it iwill also have a baffle step. The 2 qill have different radiation patterns. In a shoot-out i'd bet on the wide one.
