I am about ready to remove the GR-Research version of the BG NEO3PDR and replace it with a stock BG NEO3PDR for use in my open baffle planar speakers. They have only had fast on connectors on them, so never been soldered in place. I can adjust my digital crossover to work with the stock BG's, so no need to have this specific pair.
If someone wants a very good pair of low hour drivers, I plan to sell them for $150/pair plus shipping. I have the Parts Express plastic boxes for the stock NEO3PDR's I can use to repackage them. I bought them directly from Danny for this project awhile ago. They sound really good in my speakers.
This will give one person a chance to build an N-series speaker or other that uses Danny's NEO3PDR. I still have another pair in my N2x speakers, so not without a set at my place. I have the NOS BG NEO3PDR's now, so can swap them at any time.
PM me for details if you are interested.
