Your new room has ample space for speakers. A friend of mine bought Wilson Puppies and then treated the room to great effect. Your room is large enough for floor standers or stand mount. If you are looking for natural and musical look for a used pair of Sonus faber Olympica 3. These will fit the room and sound great. I owned a pair for many years. All Sonus Faber are natural sounding and musical. But Dynaudio, Totem can also be good choices. The Dynaudio are more detailed and still natural, Totem are fun and natural sounding. Wilson precise... and very flexible in a small room.
Recommendations for speakers in a much smaller listening room.
My wife and I are in the process of buying and moving to a new patio home. We are both pretty excited about it. The only issue is I will have a much smaller listening room. I currently have a room that is 14.5 x 38, basically one half of the basement. The new room will be 12 x 16 with 8' ceilings.(taller than pervious room at 6'8") The question is what is a good speaker for that size room that will not overload the room. I like sound stage, imaging and listenability over analytical and highly detailed. My current speakers are Tyler acoustics Woodmere II and are giant towers. I do some vinyl on a vintage Panasonic DD TT with Ortofon MC1 cart. Mostly streaming with a Lumin T2, Oppo Digital 105 for disks with a Modwright KWH 225i. Thanks for any suggestions, Allen.
