Maintenance
At High Class Musical Instrument Ltd, we understand that a sound system is an investment. Our specialized maintenance wing ensures your trademarked speakers and amplifiers deliver peak performance for years, not just months.
Our Maintenance Services
We provide comprehensive care for all professional audio gear, with a focus on our trademarked Chinese imports.
Routine Acoustic Tuning: Over time, speakers can "drift." We provide professional calibration to ensure your crossovers and drivers are perfectly balanced for your venue.
Voice Coil & Diaphragm Replacement: Using original factory parts from our Chinese partners, we restore "blown" speakers to their original factory specifications.
Amplifier Deep Cleaning: Dust is the #1 enemy of amplifiers in Nigeria. We provide internal pressurized cleaning and thermal paste replacement to prevent overheating and circuit failure.
Cabinet & Hardware Refurbishing: We repair structural damage to speaker boxes, ensuring they remain "sound-proof" and vibration-free.
