I bought 4 of these speakers just for a fun project expecting nothing more than decent speakers. Boy was I surprised when I opened the boxes and had a closer look on them...Very, very, very well made. Rigid structure, tight glued cone and a massive magnet behind can only mean an outstanding sound for the speaker of this size. I used them with a Hi-end tube amplifier and they offered crystal clear mids and quite deep bass considering they are more midrange class of speakers.
I would definitely recommend them to anyone , especially for what you get for the money. Thomann's team is nothing less but exceptional pros.
