Hi, there was an opportunity for some cs 3.7 in my area - and I took it. As a long-time owner of 1.5s they have always been my dream speakers. I knew that my living room situation would not be perfect for them because of the small space and large windows. The room is about 4x4m (12x12ft) but opens up on one side in a larger dining and kitchen area. I'm glad I bought them. Finding the perfect position is tricky and I'm sure sound would improve a tick in a larger space but overall it works out fine. In the end my fear of oversizing was unfounded. Sound is on a whole new level, much closer to a live performance. I enjoy them very much.Have a nice day!
