The LA-15F is designed for medium-distance projection applications. As a member of the versatile A15 family, this passive 15-inch loudspeaker offers extremely flexible arrangement options, high ease of use, and uncompromised loudspeaker performance.

Combined with a strictly controlled 10° coverage angle, the LA-15F delivers an impressive 144dB output, with a projection distance of up to 45 meters. The Panflex technology allows users to adjust directivity to cover audience areas of specific geometries while ensuring excellent stability in frequency response.

The LA-15F and LA-15W can be hung together or stacked to form a vertical line array. A single LA-15F (note: corrected "A15 F" to "LA-15F" for consistency with product naming) can also be used as a point sound source with adjustable directivity, suitable for applications such as front-fill or delay-fill sound reinforcement in areas requiring narrow coverage.

The LA-15F is capable of providing concert-level low-frequency response, while the LA-21SUB subwoofer can further enhance low-frequency response and extend the lower limit of the frequency response to 29Hz.

The LA-208L is a dual 8-inch line array that delivers exceptional performance. Featuring a compact size and lightweight cabinet, it meets the requirements for suspension installation and visual constraints. When used in conjunction with the LA-208SUB subwoofer, it significantly enhances the low-frequency response curve. Compared to the previous-generation system, it offers substantial improvements:

The additional low-frequency source expands the frequency bandwidth and enhances sound coherence;
Horizontal coverage control has been improved;
The integrated suspension system and ultra-lightweight cabinet greatly boost the system’s vertical coverage capability.

The LA-2212L is a dual 12-inch line array with a maximum sound pressure level of 143dB and a frequency response range of 42Hz-20kHz. It can be used in conjunction with the LA-2218SUB subwoofer. It is suitable for applications such as music festivals, theaters, and stadiums.

"We designed the LA-2212L as a true full-range cabinet, with frequency response characteristics identical to itself. The LA-2212L, boasting a maximum sound pressure level of 143dB, is a genuine large-scale loudspeaker," stated a product application design engineer from BUTTERFLY.

"To achieve such low-frequency power in such a compact cabinet, we integrated the laminar flow ventilation technology used in the reference-grade subwoofers LA-21SUB and LA-2218SUB. The side panels of the LA-2212L are molded to prevent turbulence at the port exit, thereby enhancing two aspects: output and sound quality in the low-frequency domain."

To match this additional low-frequency power, the cabinet is equipped with a high-output 4-inch compression driver. These drivers are mounted on a proprietary DOSC waveguide, feeding sequentially into Pan Flex elements that can generate one of four coverage angles: 110° symmetrical, 70° symmetrical, 90° asymmetrical left, or 90° asymmetrical right. Combined with electronic presets, manufacturers can control the coverage range for frequencies as low as 350Hz.

The LA-2212L weighs 48 kilograms per unit, with a volume approximately half that of the LA-3212, and adopts the same four-point suspension system as the LA-3212.

As part of the LA series, the LA-3212L is a full-range line source loudspeaker specifically designed for large-scale applications. It embodies all the powerful acoustic characteristics of line array speakers while featuring a lighter and more flexible enclosure. The LA-3212L is an ideal choice for applications with requirements for long-distance projection, extended frequency bandwidth, and low-frequency response, along with weight restrictions—such as domestic and international tours, music festivals, or sports events.

The LA-3212L incorporates PanflexT™ technology from France's L-Acoustic, offering four horizontal directivity patterns: symmetrical 70° or 110°, and asymmetrical 90° (left or right). By adjusting the Panflex and setting the enclosure angle between 0° and 10°, it can provide extremely precise coverage for audience areas of any geometry.

Boasting a powerful output of 147 dB and a wide frequency range from 35Hz to 20kHz, the LA-3212L combines performance and weight advantages, making it unparalleled. In addition to being used as a standalone system, it can also be paired with the LA-2218SUB subwoofer to further enhance low-frequency projection and extend low-frequency response.

When used with the LA-3212L subwoofer, the LA-3212L serves as a perfect main system for large-scale live applications, whether for traditional systems or LHISA systems.

Physical Characteristics

The enclosure of the LA-3212L is constructed from high-quality Baltic birch plywood to achieve optimal acoustic and mechanical performance. Its enclosure employs a thickness optimization process, which significantly reduces the weight of the loudspeaker while maximizing the sturdiness of the enclosure—making it highly suitable for use in large venues and tours.

As part of the LA series, the LA-21SUB subwoofer can be stacked or suspended with the LA15F/W to enhance low-frequency response and extend the lower frequency limit to 29Hz. The LA product series is a highly scalable all-purpose system that delivers concert-level sound performance for events of all sizes.

The LA-2218SUB dual 18-inch subwoofer adopts a compressed long-stroke ultra-low frequency speaker design, equipped with two high-power 18-inch bass units customized by a world-top Italian unit manufacturer. The advanced cabinet design can give full play to the characteristics of the bass units, achieving higher efficiency, lower and deeper bass effects, while reducing the cone displacement of the bass units and lowering resonance distortion.

The 6th-order bandpass speaker adds two open chambers inside the closed cabinet. Both parts work in a ported mode: one open chamber operates at lower frequencies, and the other at higher frequencies. Their combination results in a frequency response with a certain bandwidth. Compared with sealed speakers and ported speakers, it offers more flexible adjustability in efficiency and bandwidth. In addition, its bandpass frequency can be adjusted, which simplifies the parameter setting of the crossover, as the speaker itself acts as a natural crossover.

The LA-2218SUB dual 18-inch subwoofer is exquisitely made of imported high-density birch plywood from Europe. The cabinet is designed with multiple handles, greatly facilitating installation and use. It is mainly applied in large outdoor performances, stadiums, bars, exhibition venues and other places with extremely high requirements for ultra-low frequencies.
