Next Pro Audio says its new line array element LA212X, builds on the technological advances of the company’s popular LA12 line array system.
More details from Next Pro Audio (www.next-proaudio.com):
Following the huge success of the LA12 line array system and after an extended period of hard research and development NEXT announced the introduction of its state-of-the-art line array element LA212X.
Making extensive use of NEXT innovative technologies specially developed for this project, the LA212Xovercomes most of the acoustic problems usually found in vertical array systems. The result is an unprecedented combination of a sonic excellence, transparency and consistency across the coverage area even at the highest sound pressure levels.

General Description:
The LA212X is 3-way fully horn-loaded, axially symmetric, line array element, capable of producing crystal clear, detailed and extremely powerful audio performance over distance, with an exceptional 90° horizontal constant dispersion control. Being completely symmetric this line array is capable of generating virtually identical acoustic sound patterns on the right and left which allows for an easy, accurate and symmetric alignment.
It incorporates a number of technologies to produce a coherent vertical wave front, extreme sound pressure levels with exceptional accuracy and specially consistent horizontal coverage over a wide frequency range, kept down to 280 Hz. Maintaining directionality control over this wide bandwidth raises the ratio of direct-to-reflected energy, thereby increasing system intelligibility.
The bass section makes use of two 12 inch speakers with 3 inch voice coils strategically placed on either side of the speaker in a dipolar horn arrangement. The also horn-loaded mid and high frequency sections are coaxially mounted in the center of the cabinet, dramatically extending lower vocal directivity control and providing extremely smooth mid/high transition. The generously dimensioned mid frequency horn uses a 10 inch driver, while the high frequency section consists of two 1.4 inch exit HF compression drivers with 2.5 inch voice coils mounted to a dedicated wave-shaping device. To preserve the acoustical integrity and the natural warmth, all the horns, wave guides and phase correctors are made of low resonance plywood or acoustically neutral polymers.
The HF 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-length 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.
The MF 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
The speaker employed is exclusively made by the reference European manufacturer B&C. The LA212X cabinet is constructed from genuine Baltic Birch plywood and has a black textured finish. The front of the loudspeaker cabinet is protected by a rigid metal grill and the side and rear panels incorporate four handles. Two Neutric NL8 connectors wired in parallel are mounted at the rear.
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 LA212X mid-frequency section employs a Correction Phase Device which equalizes speaker’s cone acoustical path lengths and thereby minimizes high-frequency cancelations and distortion caused by phase differences, greatly vocals-in-the-face” realistic sound. High compression ratio which rises conversion efficiency to reach an incredible sensitivity of 115 dB at 1W/1m in full space.
The LF 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 more “cleaner”.
