Redesigned masterpiece

We knew we could achieve more by investing all our focus

and know-how to go beyond what’s already in the market.

It’s still 13.8”. Looks about the same. But, it’s a different

beast. The best we have ever made. With 50% higher

excursion, better performance and increased dynamics.

The new 13.8” world-class driver

• 50% increase in excursion and performance

• Improved dynamics

• In layman’s terms it has better “speed”, “attack” and

“punch”

Design features

Driver Redeﬁ nition

After thorough optimisation and testing using FEA, Klippel

and other methods, we reﬁ ned a motor featuring multiple

aluminium shorting rings with a focused ﬁ eld “T” pole

design. The result is a linear magnetic ﬁ eld over a long

voice coil throw, with very low inductance. The latest

version of this driver has been reworked and redesigned

in every conceivable way, everything has been modiﬁ ed to

squeeze out even more output, while not only maintaining

but also improving the sound quality, not insigniﬁ cantly

compared to the initial 1723 driver.

Increased responsiveness

Better magnetic ﬁ eld design with thicker aluminium

shorting rings above and below the magnet gap, which

improves control over inductance (and signiﬁ cantly

reduces it) vs position and power – this signiﬁ cantly

improves response and distortion over the older model.

The symmetrical suspension consists of a heavily analysed

NBR surround and Connex spider with integrated tinsel

leads. All combined to create a very high excursion with

linear suspension. Again, contributing to high output and

a low-distortion, precise bass.

Hybrid Cone

Our unique hybrid cone made of long ﬁ bre pulp and

ﬁ berglass, takes advantage of the pulp’s superior stiffness

to weight ratio, with the additional rigidity of ﬁ berglass

to deliver a driver of massive durability that is inherently

inert and self-damping. The result is a cone that achieves

optimum pistonic motion at all frequencies it is required

to produce and beyond, creating deep, controlled and

hard-hitting bass.
