I've been playing with the 10P for a couple of months. Here are two quick videos I shot with my iphone.

The video quality is obviously not great, but hopefully the audio is good enough to give you a rough idea of what to expect. I have the 10P crossed over close to 10 kHz.

It depends on your application, but all in all it's a wonderful driver that is fantastic down to about 70 Hz. The mids are particularly notable. I'm working on improving the lowest octave or two and have it in a large bass reflex cabinet. I feel it does miss some degree of sparkle in the upper registers, so if you are looking for something more competitive to a multi-driver unit, I feel it needs a bit of assistance beyond its sweet spot of about 70Hz - 12kHz.

I've heard the MA Alpair 10.3 and the 10P sounds more relaxed and natural without sacrificing much detail. That said, 10.3 is better at delivering bass and has more high frequency energy and presence, but it's peakier which may be more fatiguing over a long listening session.

The 10P avoids the shout of some other FR drivers I've heard, but to my ears, many drivers of this size (and larger) beam the last HF octave, so I added a tweeter with a 1st order crossover to limit that. In terms of the quality of the HF reproduction, its amazingly close to the tweeter I added up to the limits of my hearing with just a bit less of the aforementioned sparkle and air.
