2. PRODUCT OVERVIEW

The University S6 Master is a classic three-way high-fidelity loudspeaker system from University Loudspeakers, developed around a 15-inch low-frequency driver, a horn-loaded midrange assembly, and a dedicated high-frequency tweeter.

The speaker system combines the University C-15W 15-inch woofer, a T-30 midrange driver coupled to an H-600 horn, and the HF-206 high-frequency tweeter. The University N-3 Acoustic Baton crossover network provides frequency division and tonal balance adjustment for the multi-driver system.

This particular pair features brown wood-grain cabinets with a traditional vintage appearance, woven-style front grilles, and black lower supports. The cabinet configuration reflects a custom-built presentation, rather than an untouched factory-original enclosure.

HQaudios performed cabinet finishing and assembly work on this pair. Both woofer assemblies subsequently received corrective restoration, including voice-coil rewinding and dust-cap restoration. After the serviced woofers were returned, the speakers were reassembled and underwent post-assembly quality control.

The listing photographs show the actual speaker cabinets and internal components, including the University driver assemblies, N-3 crossover network, wiring, and cabinet construction.

3. HQAUDIOS RESTORATION & TESTING

Before Restoration

This University S6 Master pair had previously undergone custom cabinet work and assembly. During its earlier evaluation, the low-frequency performance required further corrective service. Both C-15W woofer assemblies were selected for restoration before final reassembly.

During Restoration

Woofer Voice-Coil Restoration: Our technicians rewound the voice coils on both C-15W woofers as part of the corrective low-frequency driver service.

Woofer Dust-Cap Restoration: We restored the dust caps on both woofer assemblies.

Cabinet Finishing: We carried out wood finishing and exterior refinishing work on the brown speaker cabinets.

Speaker Reassembly: Following the return of the serviced woofers, we installed the bass-driver assemblies and completed the speaker reassembly.

Speaker Support Refinishing: We repainted the black lower speaker supports as part of the final exterior work.

After Restoration / Final Testing

Woofer Reinstallation: Both restored C-15W woofer assemblies were reinstalled after completion of the voice-coil and dust-cap work.

Post-Assembly QC: Quality-control work was performed on the reassembled speaker pair.

Final Presentation: The completed speakers were photographed with their brown wood-grain cabinets, woven-style grilles, and refinished black lower supports.
