Term-LAB SPL Meter

Every product has a story.

Term-LAB began in 1999 with Wayne Harris' vision to create a better way to measure sound pressure level in car audio.

As competitors continued to push the limits of SPL, traditional microphone technology could no longer provide the accuracy and consistency the industry needed. Wayne recognized the challenge and set out to solve it.

In 2003, Term-LAB Sensor Technology was introduced at CES, replacing conventional microphone elements with an advanced pressure sensor designed specifically for extreme SPL environments. The result was accurate, repeatable measurements that helped redefine competitive car audio.

That innovation earned recognition at the CES Innovations Design & Engineering Showcase and laid the foundation for the measurement platform trusted by professional sound-off organizations worldwide.

From the original Term-LAB system to today's Magnum platform, our commitment to accurate, repeatable measurement has never changed.

Innovation starts with solving a problem—and continuing to improve upon the solution.

Thank you to the competitors, retailers, manufacturers, and event organizers who have been part of the Term-LAB journey for more than 25 years.

SPL is only half the story. Term-LAB Magnum + Power Probe logs voltage, current & power at the same time as SPL.

The Term-LAB Magnum combo configurations feature Power Probe integration, allowing you to measure SPL while simultaneously logging 70+ measurements and calculations, including:

* Real-Time Voltage
* Current
* Speaker Load Impedance
* True Power
* And Much More!

Because your SPL score doesn't always tell the whole story.

How much more could you learn about your system if you could see all of this data during every run?
