1. Product Introduction

The COMTOM LP-A2104L (40W) is professional 100V constant voltage waterproof column speakers engineered for demanding outdoor public address applications. Built with an all-weather rainproof aluminum alloy cabinet and high-strength ABS engineering plastic top and bottom covers, these column speakers deliver clear, bright sound output with long-throw acoustic projection designed to cover large open areas. As part of COMTOM's traditional 100V/70V constant voltage PA speaker line, they integrate seamlessly with any standard PA amplifier or IP PA controller for cost-effective outdoor broadcasting deployments across Belt & Road markets.

2. Core Advantages

The LP-A2104L features a fade-proof, deformation-resistant aluminum alloy enclosure built for years of reliable outdoor operation in harsh climates — from the intense heat of Saudi Arabia and the UAE to the high humidity of Indonesia and the Philippines. The long-throw acoustic design extends effective sound coverage distance, reducing the total number of speakers required per project and lowering overall system cost. The LP-A2104L's 40W configuration with 4×4-inch woofers and a 2-inch tweeter delivers 102dB sensitivity for maximum-coverage applications

3. Application Scenarios

These waterproof column speakers are purpose-built for outdoor and semi-outdoor environments where weather resistance and sound projection distance are critical. Mosques across Indonesia, Saudi Arabia, and Malaysia deploy column speakers for adhan and outdoor courtyard announcements — one of the largest PA speaker application markets globally. School and university playgrounds use them for outdoor assembly announcements and PE class broadcasting. Factory premises and industrial complexes rely on them for safety paging across open production areas. Gymnasiums, sports facilities, and stadiums use them for event announcements and crowd communication. Public plazas, parks, and government outdoor facilities deploy them for general information broadcasting. Ideal for ELV contractors, PA system distributors, and project contractors across Saudi Arabia, Indonesia, Philippines, Malaysia, UAE, Thailand, and Vietnam.

4. System Compatibility

The LP-A2104L operates on standard 70V–100V constant voltage PA lines, making them universally compatible with any conventional PA amplifier, mixer-amplifier, or constant-voltage power amplifier on the market. They integrate directly with COMTOM's full PA controller range, including the 6-Zone and 10-Zone PA Controllers and Supermarket Broadcast Host, enabling simple expansion into multi-zone outdoor broadcasting systems. As constant voltage speakers, they can be wired in parallel across long cable runs without impedance matching concerns, simplifying installation for ELV contractors working on large outdoor campus or industrial site deployments.
