Wayne, Most compression drivers use a 2 to 1 ration of diaphram size to throat size. This driver is 3" with 2" throat. They state resonance as 511 hz and response as 500 hz on up. I would not use this one below 1 khz. Not sure these specs make sense to me. Ron

Hey Wayne,
I would like to have them side by side.
This 2" is about ready for compensation. What do you think?
We should also compare prices as soon as we know the PSD3006 price.(If you need any T/S like the Le param. that they don't use to publish, I usually ask Professor S. Silva from Selenium Brasil.)
You may even be able to ask for a new SUB with specs made by you. The response frequency curve is away above 102dB@20K so that you don't need a super tweeter. (DPD - stands for PTC)
DPD® - Driver Protection Device – including a PTC and an HPCCR resistor, this system assures longer durability at eventual overcharge. The original .pdf for the 2" SELENIUM D3300Ti DPD is here:
http://www.seleniumloudspeakers.com/site2004/catalogo/pdf/driver_titanium_D3300tidpd_new.pdf We will know your report about the drivers and some news about your new Master Speaker design for Concert Halls.
