Dayton Audio presents its Odeum range of high-end professional speakers. The Pro 15LF is a subwoofer of incredible performance. It's based on a careful, intelligent design, enabling it to be installed in demanding systems needing to reproduce high power with fidelity.

The Dayton Audio Pro Odeum 15LF is a 38.1cm-diameter professional subwoofer capable of outperforming many other models. A power rating of 700W is achieved through the combination of a large ferrite motor, a 7.6cm voice coil with fiberglass support, and improved ventilation to increase power handling and reduce power compression. A treated paper diaphragm with accordion-like fabric suspension provides a neutral, easy-to-adjust sound. A progressive spider allows perfect control of the diaphragm's excursion.
