"Free swinging tweeter" is the latest true-ribbon tweeter used throughout VMPS line. It is one of the best tweeters available today. It's advantages over previous spiral ribbon tweeters were easily audible and cost is not overly prohibitive. We use custom version (8 Ohm, custom transformer and diaphragm) of similarly looking Aurum Cantus tweeter. The FST tweeter has 30 degrees of vertical dispersion, less than 25 mm dome tweeter, but does not become directional at 11 kHz like a 25 mm dome. Horizontal dispersion is broad and even up to 25 kHz.
Hi, from the VMPS archive site http://pointillistic.com/vmps-audio/technical.htm I found the following description of the FSTLooks like the Cantus G2Si http://www.parts-express.com/aurum-cantus-g2si-ribbon-tweeter--276-400?AID=1457483&PID=5567334&SID=skim23608X823435X6aa26b5067b0fea3c239cfb95d4b41af is not a 1:1 replacement. Has anyone replaced a FST with an aurum cantus? Will it work with the crossover in the VMPS or is it not suitable at all?Wondering whether to send my AC G2Si tweeters purchased for spare parts back to parts express...

Plus, with the trim pots, on your speakers, you can at least adjust the output to match the stock tweeters. As such, I'm sad to say, with no Brian, "that's as good as it gets!"
Hi,Was there a problem with the FST tweeter that couldn't be fixed. These tweeters should last for a very long time. If it is the ribbon they can be replaced without too much trouble.Contact John Casler he might be able to provide further information for you regarding compatibility.Cheers Rod
