Aw shucks, guys!
Thanks for your kind thoughts.
The BeoLab 9 is evolved from a "studio monitor" design project that was shelved late in the game for a variety of valid business reasons. The current design form of the BL9 is quite different from the studio monitor prototype (which was a "pure" industrial strength studio monitor shape, also by David Lewis - its purity and focus confirmed for me his genius!), but the hardware and topology of the speakers are quite similar (as well as the sound).
With that bit of background, I've always been very fond of the BL9 (during its development phase). I would happily use it for production work in a studio or mastering room. It fits beautifully in the "high-quality full-range medium-powered" free-standing loudspeaker category, and as such has few peers, much less limitations.
As I mentioned in an earlier post, I now have a pair of BL9s that I am using for "fun" listening in a sitting/reading/exercise room that is part of my master bedroom suite (it also includes a spa fitted with BeoLb 3s, just to make you envious). The sitting room is just coming on line (I'm still waiting for the reading chair to be delivered), but the listening is great. My hope is to have an excellent system that I can enjoy without "going to work!" So far, so good.
I have long fantasized a sort of uber-stereo/surround layout in the studio that would include BeoLab 9s as a discrete Left/Right pair with the BeoLab 5s in a special pentagonal array for surround playback. For the time being, that will have to wait, unfortunately. But the BL9s would certainly be suitable for that work or any reasonable studio work.
You may also be interested to know that I have now installed a high-quality video projection system in the studio, with audio running through the five BL5s. I'm very pleased with this, and find that the discrete, matched high-quality center speaker is a major improvement, actually a revelation.
I hope this is of interest.
Best regards
