IRIS-X
The coil size and electrical sensitivity of a loudspeaker transducer is critical to its performance.  Titan AX loudspeakers now include our proprietary IRIS X design which delivers Increased coil Radius and Increased electrical Sensitivity.  The radius of the coil ensures smooth heat dissipation during prolonged high volume use, while the increased electrical sensitivity ensures that the transducer converts as much electrical power into sound output as the laws of physics allow.  
A hot transducer wastes energy, risks damage and distorts.  IRIS X reduces this through improved heat dissipation and improved efficiency.
In real-world terms, IRIS X transducers deliver higher SPL with less distortion.  They lead the market with specifications and are designed and built entirely within Wharfedale Pro.

IP54 CERTIFIED
IP54 certification assures that the product has 
Limited protection against dust ingress.
Protection against splash water from any direction.
The picture shows some of the extreme testing that goes into the Titan series IP54 certification.  
All of this means that you can have full confidence installing a Titan in extreme conditions.
