Summary Description
AL-18 is a high-power low-frequency speaker consisting of one high-power long stroke 18 inch unit, combined with optimized suppression of waveguide directional holes to maximize low-frequency efficiency. It is placed on the ground for stacking or hanging as a second lowest speaker in conjunction with the AL series to expand low-frequency projection capabilities. The box is made of high-quality birch plywood, with a high-strength waterproof and wear-resistant polyurea coating on the surface. The front of the speaker is protected by a high-quality coated steel mesh combined with a breathable waterproof mesh. There are four ergonomic handrails on the outside of the box, and a three-point balanced suspension is used to connect other products in the same series. It is perfectly driven and protected by a dedicated power amplifier preset by a professional processor.
The AL-18 low speaker is suitable for the L series AL-18AP, AL-08v2, AL-20, and AL-12, which have the same width and can be directly combined to achieve array hanging or ground stacking use The AL-18AP active ultra-low frequency speaker is equipped with a professional DSP amplifier module and has undergone professional preset processing, combined with AL-18, AL-20, AL-08v2, AL-12 for perfect driving and protection
