In the four π speakers, I put a cross brace between the woofer and tweeter, spanning left to right sides and front to back. As for the smaller models with the Vifa tweeters, I had the upgrade kit listed for a year or so after introducing the versions of the speakers wih the DX25. Then I removed it because all kits now come with DX25's. The upgrade kit is $30.00 per speaker if you're interested in purchasing. As for the π logo, tell me your address and I'll send you some.
