The "Rear Phase" or Bass Reflex design utilizes the sound radiation from the back of the speaker cone to augment the overall bass response. By precisely tuning the port length and diameter, we convert out-of-phase energy into useful low-frequency output, increasing efficiency by up to 3dB compared to sealed enclosures.
Unlike standard Hi-Fi speakers, KTV speakers must handle high-dynamic vocal peaks while maintaining a rich, warm low-end for backing tracks. Our engineers optimize the cabinet resonance to specifically highlight the "vocal presence" range while keeping the bass tight and punchy.
Our cabinet production workshop utilizes CNC precision-cut high-density birch plywood and MDF. The internal bracing is strategically placed to eliminate standing waves, ensuring that the only thing vibrating is the premium driver itself.
Our facility integrates every stage of production to ensure quality control and cost-efficiency for our global partners.
From the Speaker Cabinet Production Workshop to the Painting and Assembly Workshop, every component is scrutinized. This vertical integration allows for rapid prototyping and mass customization (OEM/ODM) that decentralized factories cannot match.
Our Testing Workshop utilizes LMS and CLIO acoustic measurement systems. Every "Rear Phase Box" undergoes a 48-hour burn-in test at peak power to guarantee reliability in high-intensity commercial environments.
Located in the heart of the Pearl River Delta audio cluster, we have immediate access to world-class raw materials, from neodymium magnets to high-temperature voice coils, reducing lead times for large-scale exporters.
Our CE & Design Patent Certifications
Entering international markets requires more than just high-quality sound; it requires absolute compliance and reliability.
The next generation of Rear Phase speakers will feature integrated AI processing to automatically adjust EQ settings based on room occupancy and vocal characteristics in real-time.
Moving beyond stereo, KTV venues are shifting toward spatial audio. Our speakers are designed with wide horizontal dispersion to support multi-channel immersive setups.
