QCH 16

The QCH series employs the latest DUS AUDIO-developed Synergy Waveguide technology, successfully coupling radiation from multiple drivers into a single horn. This delivers the efficient performance of a single driver system, featuring high sensitivity, efficient power transfer, excellent directivity control, and serving as an ideal foundation for truly modular linear arrays. This coaxial synergy horn arrangement embeds the high-frequency driver within a larger horn, ingeniously utilizing the entire front baffle area as the horn, maximizing horn size and improving directivity control for lower frequencies (longer wavelengths). The QCH16 is a large-range, three-way (passive crossover built-in for mid and high frequencies) line array loudspeaker. By incorporating built-in passive crossover mode for mid and high frequencies, it effectively reduces user costs. The QCH16 is equipped with two high-power 8-inch low-frequency drivers handling frequencies below 500Hz. The mid and high-frequency section combines a high-efficiency 4-inch magnetic wafer, flat-diaphragm mid-range driver with a 1.75-inch high-frequency magnetic wafer compression driver, coupled into a 90° horizontal and 10° (adjustable in 1° increments) vertical coverage synergy waveguide horn, forming a synergy waveguide module covering the 50Hz to 20kHz frequency range. The enclosure is constructed from premium birch plywood with a high-strength, waterproof, and wear-resistant polyurea coating. The front of the loudspeaker is protected by high-quality coated steel mesh combined with breathable, waterproof mesh fabric. The exterior features four ergonomic handles, and a three-point balanced hanging accessory for connecting other products in the same series to achieve precise sound field positioning. The sound field's directivity depends on the number and angle of speakers and can be matched to the audience's geometric configuration. Through professional processor presets, it achieves perfect drive and protection via proprietary power amplifiers. The QCH16 speaker features a maximum output sound pressure level of 141dB SPL, providing ample power for audience areas within a 100-meter range. It meets the demands of large-scale mobile performances such as live rock concerts, EDM DJ music parties, variety shows, and corporate gatherings. Dus to its relatively compact size, the QCH16 can also deliver excellent sound effects when used as the main loudspeaker system in venues like indoor live houses, large dance clubs, and auditoriums.

SUM 8

SUM8 is a two-way full range speaker that uses an 8-inch mid low frequency unit combined with a 1.34-inch compression driver Unique polygonal box design that runs through the SUM series Greatly reduces the standing wave of sound inside the box The efficient unit configuration of SUM8 speakers can produce a maximum sound pressure level of 124dB in a compact volume, which is sufficient for sound reinforcement applications within a projection distance of 6 meters The SUM8 horn is designed with a horizontal coverage angle of 90 ° x vertical coverage angle of 50 °. Users can rotate the horn to maintain the SUM8's horizontal coverage ability within a 90 ° range when using it horizontally The SUM8 speaker has a continuous and smooth phase response, balanced frequency response, and constant coverage direction The SUM8 speaker can be paired with DSW series low-frequency speakers to form a complete full frequency system

DX 4.1

The DX4.1 ultra small full frequency speaker uses a 4-inch neodymium magnetic full frequency unit to handle the audio signal amplification needs from 120Hz-18KHz frequency band DX4.1 can be widely used for various language amplification or background music playback needs, with a compact size that can produce a maximum sound pressure level of 114dB, and has extremely high sensitivity and volume/sound pressure ratio Ideal application scenarios include: conference rooms, classrooms, small bars, Lounge, Background music for restaurants, sports facilities, theme parks, or other distributed high-quality sound reinforcement systems The L-shaped installation accessories can be easily fixed to various structures while still ensuring easy adjustment in horizontal or vertical directions

TOX 12

TOX12 speaker is a standard point source array speaker developed for medium to large scale sound reinforcement venues TOX12 speaker is positioned as a high-quality CLUB speaker product, carrying DUS AUDIO's persistent pursuit of high-quality speakers in various aspects such as design selection, unit configuration, and enclosure production TOX12 is a two-way full range speaker that uses a 12 inch mid low frequency unit combined with a 1.75-inch compression driver The high-efficiency unit configuration of TOX12 speaker with a continuous power of up to 400W can burst a maximum sound pressure level of 131dB in a compact volume, which is sufficient for sound reinforcement applications within a projection distance of 18 meters The horn of TOX12 is designed with a horizontal coverage angle of 90 ° x vertical coverage angle. Users can rotate the horn to maintain the horizontal coverage ability of TOX12 within a range of 90 ° when using it horizontally The TOX12 speaker has a continuous and smooth phase response, balanced frequency response, and constant coverage direction. After being processed by DSP, its performance and reliability can be further improved The TOX12 speaker can be paired with DSW series low-frequency speakers to form a complete full frequency system The characteristics of TOX12 speakers are also suitable for multifunctional sound reinforcement systems such as theaters, auditoriums, lecture halls, sports venues, etc., which can be used as the main or dispersed free combination
