DELTA-AX15

The updated DELTA-AX series features improved internal electronics. The newly designed power components ensure high performance and extreme reliability.

DELTA-AX can easily be recognised with the iconic Wharfedale Pro boomerang logo routed into the top surface.
 
Capable of producing extraordinary levels of SPL and output, inside every DELTA-AX speaker are high headroom amplifiers exclusively engineered by Wharfedale Pro. The 2 way 12” and 15” models also feature an integrated 2 channel mixer with onboard Qubit DSP insuring smoother and more controlled sonic performance.
 
DELTA-AX is constructed from birch plywood and features dual angle pole mounts to ensure that your sound is aimed directly at the audience, not at the ceiling.
 
....and it is ready for installation
Multiple rigging points and durable construction also make DELTA-AX a great installation solution. Clubs, restaurants and houses of worship around the world already rely on DELTA systems day in, day out.

ADVANCED ELECTRONICS
Around the back are a host of features

Dual mic inputs with combi-jack connections for line inputs.

RCA inputs for easy connection to consumer level audio sources.

Hands-on EQ control for Hi and Low frequencies

Balanced Link output to connect to more active loudspeakers.

Hi Pass filter switch to roll off low end when using in a monitor position.
BIRCH PLYWOOD CONSTRUCTION
DELTA-AX uses premium Baltic birch plywood construction.

Not only does this create a solid and durable cabinet, but also contributes to the overall sound.

DELTA-AX is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that a DELTA-AX will always look as good as the day you unboxed it.
ROUTED WHARFEDALE PRO LOGO
DELTA-AX features a routed Wharfedale Pro logo.

This fresh design helps to distinguish between the original DELTA-A models and the updated DELTA-AX models.

It is also a logo to be proud of. A logo that lets your audience know that the sound of your even will be of the highest possible quality.
CLASS D BI-AMPLIFIED
Inside the DELTA-AX15 are two, highly efficient Class D amplifiers.

Using convection cooling, DELTA-AX models do not use any internal fans. Fans add to product weight, ambient noise and can lead to unreliability. DELTA-AX has no fans!

The two amplifiers are dedicated to each driver. One amp for the HF and one amp for the LF. This perfect matching ensures that the DELTA-AX is highly efficient, converting as much as the laws of physics allow to be converted into audible output power.
