Peerless DX20BF00-04

Decided to throw a pair of these in the last order from PE. At the price, why not. I think I am going to match them up to either a pair of Zaph 5" or maybe another pair of Audible Physics 4". Anyway, I will try to take FR tomorrow. The impedance profile looks pretty good. I was not expecting the under 3ohm impedance though. Build quality looks to be pretty good and the Fs is darn low for a 3/4" dome.

Poorly tuned rear chamber, but otherwise looks ok.

I liked it over the ND25 crossed at 3K.  Easy to work with.

Odd question but, wouldn't it be possible for one (or more) of us DIYr's to experiment enough and come up with a better tuned rear chamber?  I don't know, just seems doable.  With so many different sized pvc pipe diameters and caps and a little epoxy it seems possible.  Maybe a bit more or different damping material?  

I think that's sort of how Dave P started his journey with making waveguides.  Cheap trial and error to find what works and what doesn't.

Absolutely Craig! These are cheap enough that destroying one is a non issue. These are all glue, no screw construction so it aint gonna be easy.

I thought the DC28 might be worth improving.  I still have my cheap airborne tweeters I tried running with no chamber...

DLR actually did mod a (current) Gen 4 Silkie, and it did improve its specs and operation. Wool for damping, etc.

I do remember that now that you mentioned it.  Maybe I'll do an open back silkie...

You know, ive never taken a tweeter completely apart just removed faceplates and diaphragm.
