SPL LAB - USB Bass Meter SE

The SPL LAB USB Bass Meter SE (Second Edition) is a precise, digital sound pressure level meter designed to measure high bass levels in car audio, home theater, and professional audio systems. With a measurement range of 10 to 120 Hz and a sound pressure range of 110 to 185 dB, the device is particularly well-suited for tuning high-performance subwoofer systems and preparing for SPL competitions.

The integrated solid-state sensor enables precise sound pressure measurement with a resolution of 0.1 dB. In addition to recording maximum sound pressure values (peak), average levels can also be determined. The measurement data is transferred via USB to a Windows PC and analyzed using the SPL LAB Measuring Center software.

This compact measuring device does not require an additional power source, as it is powered directly through the USB port. Thanks to the built-in suction cups, the rugged housing can be easily attached to smooth surfaces such as vehicle windows. No additional calibration is required for regular operation.

The USB Bass Meter SE can be expanded with optional sensors from the NEXT-LAB series via the built-in Lab-Bus connection. This enables, for example, additional sound pressure level measurements, frequency response analyses, and electrical measurements.
