NLA-8 series is 8” line array speaker system which is designed to be suitable for small-medium sized venue. Two units of 8” high performance woofer driver are equipped with the speaker, and two 1” high power titanium compression drivers are equipped with waveguide to form a line sound of upper range for line array speaker. Compression driver delivers clear voices in 90° wide range, and also able to play precise sound image by built-in phase plug.

In line array composition, it is able to play wide frequency with NLA-8 array speaker, and also user can add NLA-18S subwoofer for more powerful bass. The NLA-18S can be flying with NLA-8, or separately stacked to the ground.

The left/right side of NLA-8 is equipped with handle grip for moving and steel-made flying tools so that it can be hanging in the air conveniently. It supports two types of rigging for convenient installation: Bolt type and pin type. The rear of NLA-8 has two Speakon connectors for direct connection or parallel connection with power amplifier. Each speaker can be adjusted from 0° to 10° vertically, and different type has different increment unit: Bolt type is 5°, and pin type is 1°. According to each speaker’s vertical angle adjustment, up to 16 units of speakers’ direction angle is decided.


High quality driver
NLA-8 series adapts a high quality driver for dynamic sound and rich bass. NLA-8’s driver shows steady performance, high durability, and high input allowance for stable operation in various environments. LF driver uses forced cooldown method
to maximize heat efficiency. HF titanium driver can play clear and undistorted sound with low THD.
NLA-18S is a subwoofer with high power driver which can be used with NLA-8, or independently under the occasion. High power Long-Excursion cone type woofer in NLA-18S is equipped at front side, and woofer’s rear exhaust sound helps to
boost its bass via port. 

High frequency wave guide
The NLA-8 Series line array uses a linear waveguides to normalize the propagation distance from the throat to the mouth. This minimize the mutual interference between the cabinets. The waveguide has multiple segments changing the source into identical small apertures, each equidistant from the inlet aperture. The result is minimal rise at the mouth approximating a planar wave shape. This enables adjacent loudspeakers to sum without interference at high frequencies.

Compact acoustic enclosure
Modular type speakers such as modern line array speaker are designed with compact-sized enclosure for harmonious look with interior design. High density sound absorbing material also allows the speaker to play clear sound by preventing internal resonance.

Robust rigging system
NLA series supports bolt type and pin type system for convenient installation. The rigging system in NLA-8 is designed to safe flying installation. From 0° to 10°, angle is adjustable by 1° increment (bolt type/pin type). For the safety issue, the rigging system can stand up to 5 times of its weight when 8 units are hanging (NLA-8) and 2 units are hanging (NLA-18S) respectively.

Strong enclosure - VOID FREE
The wood material and its process are important for high quality speakers. An enclosure, which is made of a select wood and CNC process, uses DADO bonded process to maximize its durability and minimize sound leakage. Sound-optimized wood enclosure is finished by high quality painting abide by RoHS.

Support of EASE, EASE focus data
NLA Series basically supports the EASE DATA that supports the “EASE FOCUS” software. The EASE Focus supports the simple simulation for installation companies and operators and they do not need to purchase this software because it can be downloaded on the internet. For more exact simulation, the system designer can test the same file at EASE software, and it can be estimated more accurately by 3D type of data.
