[QUOTE="Helge A. Bentsen, post: 214310, member: 263"] I have a pair of old DAS R-212 in inventory. The cabinets are good (as in looks decent and solid) but the drivers are shot to pieces. I've been thinking about retrofitting them with new 12" drivers as a project. They are roughly 106L internally and port frequency is around 58hz. WinISD gives me 3 options for drivers: RCF MB12N251 has the flattest response, but I believe this driver is EOL. Beyma 12G40 looks good. B&C 12PLB100 looks goods, with a slight bump around port freq. I can get hold of all these three manufacturers pretty easy and have simulated nearly all their 12" in inventory that's labelled woofer/mid-bass. Skipped their pure subwoofer drivers. Any input on 12G40 VS 12PLB100? Anything else I should look at? [/QUOTE]
