COMPACT LINE ARRAY SYSTEM

When Waveburg acoustics decided to build & design this compact line array,it had two objectives in mind.

1-Staying away from harsh professional stereotype sound quality
2-Best & most natural possible reproduction of instruments & human tonal range at the highest possible SPL with minimum harmonic distortion.

 

This approach to design has ruled out several elements of which, using aluminum or industrial material in the construction of the high-frequency horns & waveguides. If you ever listened to a metallic or plastic violin, you will instantly realize the reason. carefully designed wooden waveguides based on the mechanical bessel function has provided the LA8 with a horizontal dispersion of 120 degrees +/- 5 .5 dB.

most impressive is the clarity & HI-FI quality of sound that resembles audiophile equipment. Along with the angles at which the 8-inch drivers are placed on the front baffle the overall horizontal dispersion is way beyond what is expected from a compact line array.
The total group delay of the Midbass drivers is 8 ms at 1.2 kHz, which is way below the norm of a pro application. This is due to the placement and the large Helmholtz resonator exit surface. coupling of the Midbass drivers to the cabinet went through a long process of reverse engineering to achieve the minimum possible ratio of vent acceleration & velocity to driver acceleration & velocity. this, in turn, minimizes the vent noise & sound coloration associated with bass reflex cabinets.

Overall speed was a primary target in the design process, this was achieved by tuning the Q of the cabinet to provide a very small cone excursion, well below the Xmax of the high-efficiency 8-inch drivers.
