Synopsis
The SA-12 was designed to be an excellent sounding subwoofer that is equally at home sealed or ported. We feel that the SA-12 is one of the best woofers available in it's price category and will satisfy the needs of a wide variety of users ranging from bass-heads to audiophiles!
The SA-12s are also gaining popularity in SPL competitions due to their excellent voice coil cooling and rugged, durable constructions with several customers achieving output well over 150 dB!
