Hi,
Over the years I have had many speakers that had some sort "device" in front of the tweeter. They invariably sounded WAY better after removal and if neccesary re-adjusting the tweeter level. Any such device I have come across always added a certain "whispy", "hissy" quality to sibilants, among other things.
I would be interested in hearing what the current MEG's would sound like with the protective mesh and the little acoustic device removed.... I guess I'd have to buy them first.
Oh, while we are at it, I also found that the best domes are inverted. Maybe one day I'll semi-clone the MEG's using Focal inverted dome tweeters, Seas paper cone midrange, a suitable 15" woofer and a Behringer DCX2496 as crossover, with a nice 6-channel Amp.
Ciao T
