Does anyone have any experience with Trenner & Friedl "ART" monitor

Larry, thanks so much for the response. Currently using Fritz Carbon 7SE mk 2 bookshelf, and really like them. I heard the ART on a u tube video through some very nice computer monitors and the sound was great. When I looked them up, I couldn't believe how small they were, but, the sound appeared MASSIVE! Prior to yesterday I had never heard of the company before. As we all have this hobby,(obsession)  you would think the name would be mentioned more often, but, not. New,  they go for about 6k. Pair that I'm looking at around 4k , full warranty, etc. Are they that good?  Room being used is 13' x13' 9' ceilings, Rock and Roll only. Sorry for being so windy. Robert TN

recklesskelly  thanks for the input. As I said above, other than hearing them on a you tube video ,had never heard the name, or on Audogon forum as far as i recall.  I have relatively small room (above post) Really like my Fritz speakers, but, always looking. In that arena of good bookshelf speakers say 3k to 7k there are a lot of choices, just bothers me as maybe it should or not a 5" driver. Where most others are 5 .5 to 7 or 8 inches?? In my set up,  I supplement my fritz with a SVS SB 3000 sealed sub (2 channel system) and it works out great, wondering if the Trenner and Friedl ART is that much better???    Last question, was your set up near field or just a small room?  Thanks so much.
