I had the chance to listen to a home made set of speakers in a fidelio cabinet with Lowther drivers. WOW !
This was the best audio experience of my life (I'm 44). It was part of an audio show, and a retired engineer had build a 5W stereo tube amp and Lowther speakers. One single full range driver, no filters or crossovers, naturally amplified.
I have to find the time and money to build myself a set
I personally would like to build a Fidelio cabinet ...
It's a new account and I cannot post links yet ... Just search for Lowther drivers.
I will post interesting links soon.
