PMS built by Albert Li/Canada
- some months later:
The sound overall is nicely balanced with admirable sweet, warm mids and very delicate, smooth highs. The lower spectrum is one of the particularly outstanding area with lots of powerful kicks. Tested with the Audiophile CD, we confirmed it goes down to 35hz, and we could feel the air movement when playing down to 20hz.
These speakers work extremely well on live recordings. You could almost touch the stage as if youre very close to the performers and you can feel the airy sound around you. Thanks for the good design that we dont have to spend much time as usual to find the sweet spot for the speakers, just simple positioning will do the trick.
What surprises us more than expected is its ability to make the listening room completely disappears. They play the recorded ambience as recorded, not in a falsely-echo kind of way, and simply allow you to identify what's on the recording. The big-sounding instruments like piano, kick drums, double bass and cello sound real. Patricia Barber live in Paris comes alive. We almost could touch and see what was going on the performing stage. The sense of impact and coherence was there.
To compare with my horn set-up, the PMS is a bit inferior in dynamic to horn.
Unfortunately horns still sound like horns, they sound more forward and edgy to my ears. Luckily the PMS cabinet coloration is not much noticeable, it confirms the concept works not only in theory but also works in practice. I enjoy every minute with it.
Anyway, if anyone reading this report is ambitious, dont hesitate to try building one for yourself. They are hard to build, but you wont be disappointed. Couple of my friends, after listening, asked me to build them the speakers. I imagine Id be damn busy if I promise.
Albert, thanks for your thorough report on your
PMS project. I'm pleased the intentions behind the project seem
to be fulfilled. A speaker must be experienced over a
certain period of time and with a wide range of
musical sources. It's very easy to be taken by a
newly finished project. All the hours going into
it and the joy of seeing the finished self-made
