REFURBISHED:

This pair of JBL 4312 speakers has undergone a complete professional restoration to bring them back to their full acoustic glory.

• Driver Service & Testing: All drivers (woofer, midrange, tweeter) were carefully removed, inspected, and tested for functionality. The woofer was refoamed with new, high-quality surrounds, ensuring tight bass response. Midrange and tweeter drivers were measured and confirmed to perform within original factory specifications.
• Crossover Network: The crossovers were recapped with modern, high-grade capacitors, securing long-term stability and restoring clarity in the mid and high frequencies.
• Ohm Verification: Each driver’s impedance was measured with precision tools to guarantee proper load matching, ensuring both speakers perform evenly in stereo use.
• Cabinet & Grilles: The enclosures were cleaned and detailed, while the front baffles and edges were refreshed for a consistent vintage appearance. The speaker grilles were cleaned and fitted with original-style JBL badges.
• Control & Connectors: All L-pads (level controls) were serviced and cleaned for smooth adjustment without noise. The rear connectors were checked and tightened for reliable connection.
• Final Testing: After reassembly, the pair was thoroughly tested with reference music and frequency sweeps. 

Results confirm balanced tonal response, strong bass, clear mids, and smooth highs true to the JBL 4312 heritage.
