Next-Proaudio LA212X is a 3-Way Fully Horn Loaded Line Array Element offering extreme SPL and throw capability.
Main features and specification for Next-Proaudio LA212X:
The Bass Section
- Fully horn-loaded, axially symmetric, Line array
- Extreme SPL and throw capability
- Uniform dispersion and great coverage control
- Horizontal Coverage maintained down to 280 Hz
- Easy and fast rigging system with variable splay
- Type: Horn-Loaded 3-Way Line Array Element
- Freq. Resp. (-6dB): 60Hz - 19.000Hz
- LF Extension (-10dB): 52HZ
- Maximum SPL: 138dB/144dB (Full-Space)
- Dispersion (HxV): 90° (Down to 280Hz) x 8°
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 LA212X 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 [email protected]

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 3 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.

Next-proaudio LAs418 is a Double Bass Reflex Subwoofer designed to offer ultra-low frequencies at a very high SPL.
Main features and specification for Next-proaudio LAs418:
- Dual very long excursion 18" bass reflex design
- Optionally arrayable
- High maximum pressure
- High dynamic and extended response
- Large ports areas for reduced distortion
- Type: Passive Very High Power Reflex Subwoofer
- Freq. Resp. (-6dB): 28Hz - 250Hz
- LF Extension (-10dB): 24HZ
- Maximum SPL: 143.8dB/149.8dB (Half-space)
- Power (Pgm/Peak): 6000W/12000W (10ms)
Housing two long excursion and very high power 18" drivers, this Subwoofer has been designed to offer ultra-low frequencies at a very high SPL delivering magnificent precision and punch at incredible pressure levels.
The cabinet volume with optimized port tuning - featuring extremely high peak-to peak excursion capability - is capable of delivering true sub performance down to 24Hz at -10dB. Providing low frequency resolution and a maximum SPL of 143.8dB in a 94kg, front loaded, bass reflex enclosure and measuring 516mm x 920mm x 1030mm (HxDxW), the new subwoofer version incorporates eight handles and a rigging system.
Housed within a multi-laminate birch plywood enclosure and finished in textured black semi-matte coating, the LAs418 can be deployed in either standard or cardioid configuration using the parallel wired Neutrik NL4 conector on the front of the Subwoofer.
The 2x4ohm LAs418 version has been designed to be driven by Powersoft X series (X4 or X8). This new version presents an increase of 4dB of SPL when it is driven by the Powersoft X Line amplifier while compared with MA6000 driving the normal version, the LAs418.
