Like the Manger bending transducer, AMT and ribbons the LMT is an weideband alternative to doe tweeters.
Manger speakers are beautiful, if I had the budget. AMT speakers sound also really good, I had the chance to listen to Abacus AMT active speakers. Sounded great.
Likewise I had the chance to compare Burmester B38 to Piega ribbons, about the same price. Listened together with my sister. It became apparent that women are much more capable of hearing heights. My sister preferred the Piega Ribbons and I the Burmester, the balance between bass and height was much better with the Brmester to me for my sister the bass was more in balance with the Piega and she found the heights just amazing, for her the best.
I love the Sonus Faber sound also and they utilise a soft dome tweeter. My Yamaha MSP 5 Monitors have metal dome tweeters and they reveal any detail.
So I find the discussion about driver types a bit academic really. It’s the complete speaker that makes the sound and different people have different preferences.
