About the ISOLINE_AX Series

Discrete and punchy – Portable and practical! 

A self-contained live sound solution for live performance. The hardest choice to make is….. ‘which model’?

‘Practicality’ was a key goal for the design team. To make an active system with features that make setups and break-downs easy. The column uses direct coupling to make connection fast. The column itself is also rotatable by +15% / -15% to ensure the output really covers the audience.

With microphone, line, USB-drive and Bluetooth inputs, the system also reduces the need for an external mixer. In addition, two ISOLINE-AX arrays can be paired wirelessly using TWS technology.

Importantly, the latest HF technology has been deployed and BOTH ISOLINE-AX models feature a mini EVO-Fold waveguide ‘evolved’ from the incredible WLA-1 Hybrid Curvature Array system.



Built into the subwoofer are the inputs and controls.

A 2-channel mixer for mic and line inputs allows for quick and easy connection.  A central USB input allows for files to be played back from USB storage devices and Bluetooth input can be controlled from here too!

Practical High and Low EQ knobs also give +9 dB / -9 dB of control to allow an ISOLINE-AX to be tuned to the performance environment.


The column containing the wide-range drivers and HF compression drivers can easily be rotated. by + 15° / -15° which allows you to direct the system fully towards the audience.


ISOLINE-AX subwoofers are constructed using our baltic birch plywood.  This ensures physical stability of the enclosure, even at maximum power.


Mini EVO-Fold waveguides ensure  system phase coherence.  These highly engineered waveguides come from our incredible WLA-1 line array system.

ISOLINE-AX912 has two, and ISOLINE-AX510 has one mini EVO-Fold waveguide which are directly coupled to the HF compression driver / drivers.

The EVO-Fold combines a unique folded and manifold design. The most advanced FEM technology has been used to create this.

The high-mid energy exits produce a uniphasic sound in the widest range of frequencies. And visually, the detail of the EVO-Fold waveguide is a work of art.


ISOLINE-AX has been engineered to ‘make things easy’.  Connect the subwoofer to the base.  Lower the column onto the base.  Easy.


The HF compression driver delivers additional clarity and performance with enhanced definition.

It is custom made by Wharfedale Pro and is coupled to the mini EVO-Fold waveguide resulting in 120° x 30° dispersion (ISOLINE-AX912) and 100° x 20° (ISOLINE-AX510)
