15-SRX12D4 - Memphis 12 250W RMS 500W Max Dual 4-Ohm Street Reference Subwoofer. The Esotar² 1200 Subwoofer features a unique construction: a massive dual-stacked magnet system powers a large 75 mm diameter aluminum voice coil and MSP cone diaphragm. Dynaudio's exclusive MSP material provides the ideal combination of rigidity, light weight and excellent inner damping to naturally reproduce the lowest frequencies without distortion.
The Esotar² 1200 utilizes an ultra-rigid die cast frame basket to ensure the most anti-resonant foundation of a powerful, accurate and controlled bass response. Thanks to the innovative Dynaudio construction with precise parameters and extremely tight tolerances, this newly-designed 30 cm (12) diameter woofer has been optimized to achieve the most advanced sub-bass performance. And due to the very low distortion and an amazingly quick rise response, the Esotar² 1200 is also extremely easy to seamlessly integrate into any high performance autosound system. Combining powerful yet deep bass performance with incredible extension down to 18 Hz, the Esotar² 1200 reproduces the highest sound pressure levels down to the lowest notes by precisely following the amplifier's signal, even at the highest output levels.The Esotar² 1200 brings Dynaudio's most sophisticated engineering and development into the world of automotive subwoofer systems to establish another car audio industry benchmark. Diaphragm with very high excursion, 58mm peak-to-peak. Rigid die-cast chassis with aerodynamically shaped ribs. Materials and parameters are optimized for the harsh environmental conditions in a car.
