Vapor Sound Joule Black 2.0


Producing a reference level full-range speaker is a daunting task. With the increase in size and number of drivers, the importance of proper execution increases exponentially. With The Joule series all options were on the table, only after evaluating the world’s best drivers and researching new cabinet materials did we start prototyping the design. Finally after nearly 2 years of development and multiple prototypes was The Joule Black born.

Like all models in the Vapor lineup, we begin by building the perfect cabinet.  And with the Joule, the cabinet is a work of art all by itself. The construction consists of two independent pieces for the bass driver cabinet, and for the midrange/tweeter cabinet.  Each piece isolated from the other via Herbie’s Fat Dots.

The bottom bass section is a stacked Birch-ply construction, with a tapering Transmission Line integrated into the CNC cuts.  Using the CNC and assembling the cabinet this way not only gives incredible strength, but allows us to give the Transmission Line the ideal amount of taper from beginning to end.

The top section is also CNC cut stacked Birch-ply made in the same shape as the Cirrus cabinet, thus allowing us to take advantage of the Finite Element optimization that was engineered into that shape.  The front baffle is made of 8 layers of high-density thermoplastic and aluminum sheet, which form an incredibly dense and strong launch platform for the music signal that is also well damped.  To blend it all together visually are complex CNC’d 3 dimensional shapes, end result is a stunning visual creation.

And the drivers are just as beautiful as the cabinet. Providing the bottom end foundation is the Class Leading AudioTechnology 10C77 Sandwich Cone woofer. This woofer is an example of what can be built when cost is no object, and provides bass speed and impact unmatched by any other. The midrange is the AudioTechnology 15H SDKAM, a midrange that’s not only dynamic and engaging but also musical and romantic.  And topping it all off is the RAAL 140-15D, in our minds the finest tweeter to be found at any price!

To top it all off only the finest components are used throughout the build such as Clarity MR Capacitors, Jensen 12ga wax/paper inductors, and Duelund resistors. The Joule Black is easily capable of differentiating sonic changes of crossover components, so we've chosen some of the finest as our starting point.
