DAYTON AUDIO PRO 12LF ODEUM Subwoofer 400W 8 ohm 94.5dB 30hz-1500Hz
Dayton Audio presents its Odeum range of high-end professional loudspeakers. The Pro 12LF is a subwoofer with incredible performance. It is based on a careful, intelligent design, enabling it to be installed in demanding systems requiring high power reproduction with fidelity. Here are the highlights of the Dayton Audio Pro 12LF subwoofer speaker:
- High-quality construction for a robust product
- Balanced SPL/Xmax ratio provides power and reach
- Powerful Y35-grade ferrite motor
- Treated paper cone for optimum strength and durability
- Progressive-winding spider for better cone control in case of strong excursions
- 3" voice coil wound from the inside out on a fiberglass support for good power handling
- Excessive ventilation to reduce power compression
- Unidirectional linear Xmax over 9 mm for enhanced low-frequency performance
Dayton Audio Pro 12LF: a professional low-frequency loudspeaker
The Dayton Audio Pro 12LF is a 12" professional subwoofer that guarantees superior performance in a PA system. This speaker achieves up to 400W RMS power thanks to a ferrite motor and a 3" voice coil with fiberglass support. It also features extended ventilation for subwoofer power handling and reduced power compression. The treated paper cone with fabric suspension provides a neutral, easy-to-tune sound.
Dayton Audio Pro 12LF: a speaker built to last
The Dayton Audio Pro 12 LF loudspeaker delivers big power in a small form factor. The large motor demands impressive control and enables a low Qt of 0.21, meaning it's ideally suited to small, vented loudspeakers. An impedance of 8 ohms means that a pair can be used in a space as small as 2.3 cubic feet (65L), with a high-output design that supports 800 Watts and extends to bass at 30Hz, achieving sound pressure levels in excess of 94 dB.
