Avantgarde Uno Nano suitable for small room?

You will love the Lamms with Avantgardes. The room sounds tight but doable; the key as Brf noted is to sit 10+ feet away, but while also preserving width (tweeter to tweeter) of 83% of the distance from each tweeter to your respective ear, so to sit exactly 10 feet away the centers of the tweeters should be 8.3 feet apart. This will place the outside of the mid horns very close to side walls. Luckily the speakers are very directional so placement near side walls is of little concern. Good luck!
