Concrete Audio not only shows that this material does not have to look industrial and rough, they also show us that an acoustically dead cabinet doesn't necessarily sound dull or shut-in. On the contrary they produce a lively soundstage.

The business is owned and operated by our CEO, Calvin Thedinger, who took over leadership in 2020 at age 23 following the untimely death of his older brother, Coleman (founder of CT Sounds).

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.

Through product innovation and brand actions, we support mobile, powersports, and marine audio enthusiasts everywhere to strategically harness the true power of sound. After 50 years, MTX Audio remains an American family-owned manufacturer with an unwavering commitment to its employees as well as our customers.
