We’ve heard it all before. Fred’s truck hits 190dB. (Ok about 145dB) Of course, “Seeing is Believing.” Until recently, proving that meant access to an expensive SPL meter. Sure there are less expensive meters, but the accuracy and maximum SPL capability leaves much to be desired. The people at saw an opportunity for an inexpensive but accurate SPL meter. The dBm2 is result.

The dB-2 is a compact, self-contained 150dB SPL meter. The dB-2 contains both the electronics and microphone inside its 1.75” x 4.5” x 3.5” black chassis. Power is derived from the supplied 12 volt cigarette lighter adaptor. The dBm2 mounts to your vehicle with two placed suction cups or can rest on your dash with the supplied mounting feet.

It’s hard to beat the performance of the dBm2. Given the price on the unit, the dBm2 offers an affordable alternative to higher priced SPL meters. This unit would be equally at home either in an installer’s tool box or in the hands of the SPL enthusiast. What it gives up in features, it more than makes up for in portability and ease-of-use. If you want to really know what SPL level your system is capable of achieving, the is a great inexpensive solution. Hard core competitors will still need to rely on using the exact test equipment used by the judging originations. For everyone else, the dBm2 is the perfect choice.
