FINE QC 2026: Complete Loudspeaker QC Testing
in under one second

LOUDSOFT has updated FINE QC for 2026, providing a complete loudspeaker quality control test covering SPL, sensitivity, polarity, impedance and Rub & Buzz in under one second.

Designed for production and quality-control environments, FINE QC combines automated testing, statistical analysis and pass/fail control in a complete loudspeaker QC system.

Complete Loudspeaker QC Testing

FINE QC 2026 can perform the key tests required for loudspeaker production quality control, including:

SPL

Sensitivity

Polarity

Impedance

Rub & Buzz

The complete test can be performed in less than one second, making the system suitable for high-throughput production environments where fast and repeatable testing is essential.

Automatic golden average

FINE QC can automatically create a Golden Average from measured good units.

Saved statistics can then be used to establish the reference performance for production testing, providing a consistent basis for evaluating subsequent units.

The system also supports defined pass/fail limits and automatic storage of test results.

Serial number and barcode testing

Production testing can be linked directly to individual units.

FINE QC supports:

Serial number printing

Defined pass/fail limits

Barcode-based test start

Saved test statistics

Starting a test by barcode allows the production process to be integrated into a simple, repeatable QC workflow while reducing manual operator input.

Simple Rub & Buzz setup

Rub & Buzz testing can be configured using actual production samples.

The setup process is designed to be straightforward: measure a selection of known good and bad units, allowing FINE QC to establish the basis for detecting Rub & Buzz defects.

This provides a practical approach to one of the most important subjective and difficult-to-automate aspects of loudspeaker production testing.

Complete FINE QC Hardware System

FINE QC 2026 is available as a complete system including dedicated LOUDSOFT hardware.

The 19-inch FINE hardware includes:

USB connectivity

Phantom microphone input

25 W amplifier

FINE QC for Loudspeaker Production

FINE QC is designed for professional loudspeaker manufacturers and production environments requiring fast, repeatable and automated quality control.

By combining acoustic and electrical measurements with automated pass/fail evaluation, Golden Average statistics, barcode operation and Rub & Buzz testing, FINE QC provides a complete production test workflow in a single system.
