Expert Repair Services for Classic LS3/5a Monitors
After decades of service, even the finest monitors require professional attention. Our restoration services address the most common issues facing vintage LS3/5a units:
Drive Unit Testing & Replacement:
We provide authentic, technically matched replacements for the KEF B110 woofer and KEF T27 tweeter, ensuring the delicate balance of the original design is preserved.
Crossover Calibration:
The LS3/5a crossover is famously complex. We test and calibrate original networks, replacing aged capacitors with modern, high-tolerance equivalents that match the original BBC specification.
Cabinet Resealing & Damping:
Air leaks and degraded damping material can compromise bass response. We restore the acoustic integrity of your cabinets using period-correct materials.
Tygan Grille Replacement:
We offer authentic Tygan grille cloth and frame repairs to keep your speakers looking as good as they sound.
Performance Upgrades:
The Gold Badge Standard
For owners looking to take their listening experience further, we offer exclusive upgrade paths developed through years of research and the production of our own LS3/5a units.
The Gold Badge Crossover Upgrade
Experience the pinnacle of LS3/5a performance. Our Gold Badge Crossover upgrade features ultra-low-loss inductors and custom-made capacitors, mounted on a high-spec PCB. This upgrade significantly improves clarity, reduces the noise floor, and enhances the overall musicality of any compatible LS3/5a model.
Internal Wiring & Terminal Upgrades
Minimize signal loss with high-purity internal cabling and heavy-duty, gold-plated binding posts. These upgrades provide a more secure connection and improved conductivity for modern high-end amplification.
