Yep. My lowly B&W 802 series 3 were probably built in 97' when I discovered Troels Gravenson speaker building designs,I was stoked when he does a crossover upgrade for these speakers. I couldn't buy the kit fast enough, talk about a fun project. Most rewarding project I've ever done. I'm gonna tear into them again one day and replace these parts with even better Jantzen parts and silver wire. I could've easily asked Jantzen for his better products and wish I would've.
A diy speaker project is in the works also.
