I saw this loudspeaker at the audio show 2 years ago, so I can’t tell you more than I liked it and felt it was one of the better loudspeakers at the show in terms of tonal balance. It was small and very expensive for what it was, but then being a boutique item, I can understand how they’d have to charge that much for it given a small production run.
I’m a mid-range freak. For me the most important thing in a loudspeaker that the mid-range do a good job on voices and acoustic instruments. The demo recordings I bring are voices and instruments I know well.
I still think a DIY project using that Tang-Band full-range driver could be a lot of bang for the buck, especially if you add in a good DSP EQ like the
miniDSP DDRC-24. There are a couple of things you could do with this driver. One would be to use it as the heart of an open baffle system. The other would be to get enough of them to make up an open baffle line array. That could be loads of fun.
One more thing. If you're really thinking of spending the $6700 they were asking for that loudspeaker at the show, I think
this used pair of the Avalon Opus would be a much better value. They are my own "wet-dream" loudspeaker.
