REFURBISHED DETAILS (FULL RESTORATION)

This pair of JBL 4343 Studio Monitors has undergone a complete, high-level restoration by HQaudios, following our strict procedures to return the system to its original studio-monitor performance while refreshing the visual presentation with premium materials.

1. Cabinet & Finish Restoration

Original walnut veneer was sanded, repaired, and refinished to achieve a clean, warm, and luxurious appearance.

Corners and edges were corrected, ensuring the cabinets stand solid, square, and vibration-free.

Rear panels refinished in factory-correct matte black.

Internal damping materials checked, cleaned, and restored to proper density.

The result is a beautifully restored cabinet that maintains JBL’s vintage studio look.

2. Custom Front Grilles – New HQaudios Build (Dark Blue Tone)

Grilles were rebuilt using new frames, fresh cloth, and precise tension for perfect alignment.

Cloth color is a deep blue studio tone, slightly different from the traditional bright monitor blue — more refined, modern, and visually clean.
