Hey guys,

I had a bit of an experiment I wanted some comments on... I have owned a lot of PSD 2002's and one thing that has always irked me about them is that rear chamber. It's tiny and it's reflective. I can only imagine how many frequencies are being bounced around in that rear chamber, causing smearing, frequency response spikes and who knows what else.

Would there be any positive results from building a damping chamber onto the rear of PSD-2002's to obsorbe and diffuse the rear waves from the compression diaphram? My car horn compression drivers have such a chamber on them and it seems to work pretty well... thoughts?
