The TREO Series improved subwoofers offer world-class sound quality with a wide spectrum of musical styles.  High efficiency means maximum sound even with little amplifier power.  The TREO Series improved subwoofers were designed with the same principles and technologies as our competition woofers.  At TREO Engineering we never settle.

The TREO Series improved subwoofers come into the new year with a host of improvements. The new models feature new cosmetics with siler powder-coated baskets, a new wrap-around concealer gasket with an embedded TREO logo. The speaker has also been upgraded with a new spider with integrated tinsel leads and a former ring that reinforces the critical cone-spider-former joint.
