I recently bought/ tried several smaller speakers as there were some incredible prices. The latest I got is the B&O Beolit 15. I can really recommend it as a monitor and e.g.for small churches with quiet audiences. The bass is absolutely incredibly deep, and the general sound is very refined although not neutral.
With these small speakers You have to pay attention regarding distortion with piano sound. While normal/orchestral music is often rendered without any problems, pure piano sound sometimes causes a very bad distortion in the upper third of the volume range.
For this reason I recently returned the Vifa Helsinki, an absolute high end speaker. It couldn't cope with the massive mid frequencies of a piano sample. Same applies to the Sony SRS-X88. The Beolit 15 has absolutely no problem with it.
