I was really surprised by the clear sound that was produced by this "little"speaker. It is connected to my tube-amplifier and is has a very good stereo-staging. My livingroom is not to big and the sound that is produced by the audio pro is more than settisfying. enough bass. Mu tube-amp produces 2 x 13 watt at 8 ohm. i only play vinyl and i can listen to it for ages. i am glad that ihave these little speakers. If you can get a pair please do and you won't be dissapointed.
