There have been some minor (and I do mean minor) adjustment in regards to the material used on the top ramp of the speaker. There was an inexpensive stiff felt sound damping material from Amazon that NXSTUDIODRUMMER informed us of. It does work well to add a little more sparkle and airy nature to the tweeter if your gear could use it. Search on this site and I know you can find a link to it. Other than that, Danny nailed it on design and application from the start. Max out the crossover as best as you can, supply good source material via well thought out system components, and go full OCD on your room setup to get the most out of your speakers.
Just curious, what gear are you running and what's your current room setup?
