SPL stands for sound pressure level and is also commonly referred to as efficiency and sensitivity. This parameter represents how loud a speaker is. A higher SPL equates to a louder speaker. A speaker is placed on a baffle with the cone facing into an anechoic chamber (room designed to stop sound reflections).

JL Audio will continue operations at its current headquarters in Miramar, Florida, and in its facilities in Portland, Oregon, and Phoenix, Arizona. The company employs more than 600 associates who will become part of the global Garmin team.

JL Audio was founded in 1975 by James Birch and Lucio Proni. They used the first letter of each of their names, to form a company name, hence "JL." Their first products were home speaker systems as well as home speaker kits.
