 LA212X - 3-Way Horn Loaded Line Array Element

 

The Bass Section

Two 12" (3 inch voice coil), high Bl (Force factor), neodymium low frequency drivers are loaded by two proprietary hybrid-horns. The horn mouths are horizontally separated by a "tuned" distance that uses the Tuned Dipolar Array effect to achieve exceptional low frequency horizontal dispersion control with the nominal angle being maintained down to 280Hz. In a live situation, the low frequencies optimal directional control provided by this technology will prevent LF signals from the sound reinforcement system to reenter the live stage leaving it much “cleaner”.


The Mid Section

The mid-frequency section is equipped with one high-performance 10 inch speaker (3 inch voice coil), mounted coaxially behind the HF drivers, loaded by a, mathematically complex, directivity control device that cleverly eliminates the HF section acoustic “shadow”. Due to the physical diameter of 10 inch driver it is impossible to achieve interference-free, close coupling of wavesources at the frequencies necessary to crossover with HF drivers, so a proprietary WAVE SPLITER device was developed. This device causes the 10 inch driver to behave as twin adjacent 5 inch drivers mounted at half the physical distance. The distance between these adjacent virtual drivers is close enough to couple coherently in the vertical plane extending the upper frequency limit for line source behavior, projecting sound waves farther than traditional systems with a more evenly distributed sound output pattern. In addition, the LX212 mid-frequency section employs a Correction Phase Device which equalizes speakers cone acoustical path lengths and thereby minimizes high-frequency cancelations and distortion caused by phase differences, greatly increasing the speakers ability to produce clear, accurate and “vocals-in-the-face” realistic sound. This device and the associated horn are optimized to create a high compression ratio which rises conversion efficiency to reach an incredible sensitivity of 115 dB at 1W/1m in full space.


The High Section

Knowing that is in the mid/high frequencies that our ear is particularly sensitive to detail, our engineers dedicated much care and attention in the design and development of this unit, deeply optimizing its performance. This High Frequency section is composed by two 1.4 inch exit HF neodymium compression drivers with 2.5 inch voice coils mounted on a dedicated wave shaping device. This unit is carefully designed so that each path-lengh from the throat to any part of the mouth is precisely identical, which provides accurate high frequency summing and the generation of a flat, isophasic wavefront.~ The wave then exits by a diffraction slot to a constant directivity wave guide that spreads out evenly across the horizontal plane, producing a cylindrical wave that couples coherently, with minimal lobing, in the vertical plane while uniformly disperses on the, non-coupling, horizontal plane.
