Ideal for Retro-fit and MDU markets

Pinnacle has developed the first high performance ON-CEILING speaker that delivers audiophile performance; ideal for the retro-fit and Multi-Dwelling Unit (MDU) markets.   

The OC HT 1 is the ideal sonic solution when ceiling placement is the preferred location for your music/Home Theater system.  The circular cabinet of varying depths enhances the bass response by virtually eliminating standing waves.  This cabinet design results in cleaner, better defined bass with an improved attack / decay ratio. 

The OC HT 1 is the perfect solution, particularly for the retro-fit and MDU (multi-dwelling units) markets.
