This is what i am aiming for in my restore of my own 828 boxes That big cell is a suburb horn and really spotlights the vocals in music . ! The 2405 is one of the best super tweeters ever made.
I know right? It doesn't sound like the highest fidelity I've ever heard and yet at the same time you can't help but want a pair anyways. Nothing quite sounds like it and you know you've heard them before so it's kind of like bumping into an old childhood friend again.
Why do people do a demo video of speakers and then put the camera/mic behind the speakers and move all around the room. There is a sweet spot in the room where you can actually HEAR the speakers. It tells me you are interested in eye candy, not sound. Oh well off to a different video.
