Subwoofer Technologies

All-new mid/bass drivers
At the heart of the 907 Subwoofers are new optimized, re-profiled, propriety CPC™ bass drivers designed using the latest CAD technology. The drivers incorporate unique radial ribbing on the surface of the anodized aluminum cone. This ensures excellent critical rigidity at the cone edges for truer piston-like behavior.

Front coupled surround edges
A new manufacturing process involving a folded return assembly, enables coupling of the surround edges to the front of the aluminum cone. Not only does this deliver improved damping but, it also allows a more linear motion of the drive unit. The surround sits on a proprietary shallow profile, steel chassis.

Vented, structured steel chassis
The drive units incorporate novel steel front mounting, which features a unique vented, multi-fixing point design. The combination of extra strength, provided by the profiled steel and multiple fixing points create optimal structural rigidity. This produces a more linear operation with lower mechanical noise.

Enhanced cabinet construction
The subwoofer's revised cabinet design makes use of an optimized internal bracing layout at critical points and uses a new construction technique that leads to improved structural integrity and acoustic damping. A reduction of the cabinetÂ’s width, by 15mm, also helps performance, while side mounted, molded cabinet feet offer greater stability without increasing the overall footprint of the speaker.

Lightweight cone to voice coil coupling
Low mass, high efficiency, viscous coupling of cone to voice coil, using our “5 POINT” polymer sub-cone and aerospace approved, viscoelastic bonding system.

About Mordaunt-Short:

Mordaunt-Short has been designing and manufacturing loudspeakers for more than thirty years. Naturally, we have seen a great many changes in that time. Our company has maintained its leading position by consistently responding to - and frequently introducing - new technologies and materials.

However, one factor has remained more important to our success and has guaranteed the continued satisfaction of our customers: a passion for music. We certainly relish pushing technology but we refuse to release a new model simply because it's innovative or technically superb.

No loudspeaker leaves our factory until it has passed the one test that really matters: its musical performance has to put smiles on the faces of everyone in our listening room.
