COMPACT LINE ARRAY SYSTEM
 

Waveburg Pro decided to build & design this compact line array with two objectives in mind. Challenging the stereotypical harsh sound that is common in Pro audio; and providing the best and most organic reproduction of instruments and voice with the highest possible SPL and least possible harmonic distortion.

 

This approach to design has ruled out several elements commonly seen in the industry like plastic and aluminum. Then concept emerged from the study of materials used to make violins. It became apparent that the only material able to reproduce the full and rich sound of a violin would be wood. Imagine listening to an aluminum or plastic violin? Its easy to see why Waveburg chose a carefully designed and handcrafted wooden waveguide over what is typical to the industry.

 

What’s most impressive is the clarity & HI-FI quality sound, matching that of audiophile equipment from any position. The angles at which the 8-inch drivers are placed on the front baffle allow for an overall horizontal dispersion that completely surpasses what is expected from any other compact line array, measuring +/- 5.5 dB at 120 degrees.


The total group delay of the Mid bass drivers is 8 ms at 1.2 kHz, which is well below what is normal of a pro application. Waveburg achieved this through the placement and size of the Helmholtz resonator exit surface. 

 

The coupling of the mid-bass drivers to the cabinet was a long process of reverse engineering. The goal was to achieve the smallest possible ratio of vent acceleration/velocity to driver acceleration/velocity. This minimizes the vent noise & sound coloration associated with bass reflex cabinets.

The largest target in the design process however, was overall speed. This was achieved by tuning the Q of the cabinet to provide a small cone excursion well below the X-max of the high-efficiency 8-inch drivers.
