Akhilesh, the problem I've found with dome tweeters is that it's hard to find one with a high enough sensitivity to match fullrange. Most domes are at 90db with a handfull in the 93db range. Ideally, I'd like to have something at least 95db.What about the use of piezos as super-tweeter? Looking at specs, many of these units go up to 30kHz. Never considered piezos until I saw the $300 unit offered by Phy-HP.
