Surprise, surprise it is from Pass Labs and the model name RS1.  I have no other comments besides the visual appearance of the RS1 loudspeaker and I find the RS1 being remarkably elegant, functional and beautiful. I was thinking something similar during design my MiniMe project but the Pass Labs’ designers took it further and truly make it gorgeous.

Good job, Mr. Pass!

I wonder if you can do some "sound forecast" just by looking at them. The drivers seem to be of some sort of synthetic plastic material, which were true, I fear wouldn't sound much of my liking. They remind me of the Watt&Puppy, Joseph... and some French speakers you already listened a few years ago in some exhibition.
The ASA Grand Monitor:

It'd be nice knowing some specs. Quite pricey though, but were they able to sound right, perhaps could be considered a bargain compared to other "high end" speakers similarly implemented.

Antonio,

The drivers are Seas Excel:

http://www.seas.no/index.php?option=com_content&task=view&id=32&Itemid=43

"The SEAS Excel woofer Line offers 2 proprietary cone materials, available in drivers sized from 12 cm to 26 cm. SEAS is the only loudspeaker company in the world to offer high purity, die-cast and machined magnesium cones. These cones feature extremely high stiffness along with good internal damping. SEAS Excel Magnesium cone drivers are world renowned for their high definition, low distrotion and sound reproduction.

For those listeneres preferring soft cone drivers, the SEAS Excel Line offers our exclusive Nextel series. Excel Nextel drives feature a "sandwich" construction of paper, coated with Nextel paint on the front surface and damping compound on the rear. The resulting cone is both lightweight and well damped; offering an extreremly linear frequency response.

All SEAS Excel woofers feature advanced motor structures utilizing copper shorting rings above and below the gap, as well as solid metal phase plugs for superior acoustical performance and enhanced cooling. "

Cheers,
Tuga

Antonio,

I have no business (or frankly speaking interest) in production Sound of new Pass Labs loudspeaker. Not to mention that any more or less credible prediction I am able to make only with horn-loaded setups, otherwise my knowledge of the condition in box speakers and my familiarity within box drives (particularly contemporary) is very inadequate.

I was commenting about visual appearance and certain sense of dimensional balance that I found remarkable in new Pass Labs loudspeaker. BTW, there is another worth to mention thing in this loudspeaker – they looks like have a built-in option for external crossover. I do not know how it makes sense in this speaker but I am sure that for company that sells amps it does make sense to pursue a multi-amp configuration…

What distinguishes the Nextel drivers from most of their competitors is the strong damping, both of the whole system (Qm) and the cone (short settling time for a paper cone, nothing that could be called a resonance). According to the theories of some (e.g. parts of the DIY-hifi press) this should be the ideal ingredients for a boring performance (what is absolutely not true from my personal experience).
I wonder if they could make a high sensitivity driver based on the W22.
