The Esotec MW 172 is a 20 cm (8 inches) diameter mid/woofer designed for high-performance two-and three-way systems.
The MW 172 will perform extremely well in a wide range of enclosures, either sealed, vented or free-air. The MW 172 exhibits a unique combination of smooth frequency response, low distortion, and extremely powerful bass to deliver outstanding sonic performance in any high performance two- or three-way system. The MW 172 utilizes an oversized 75 mm (3 inches) diameter voice coil to drive the MSP one-piece cone diaphragm. The 15, 17, and 20 cm Esotec MW car series woofers all utilize new ultra compressed dual ferrite magnets positioned inside the coil to produce maximum utilization of the magnetic energy. The powerful double magnet system utilizes a vented pole piece for additional cooling. Positioning the magnet structure inside the voice coil enables the use of a very large voice coil, which in turn produces increased power and efficiency and yields a linear movement of the cone without breakup. The phase response is smooth and uniform. The large diameter of the voice coils provides the optimum drive of the diaphragm and guarantees enough headroom with regard to power rating while assuring perfect control of even the most minute membrane displacement. The MW 172 is a perfectly balanced driver with excellent dispersion, a linear frequency response, and an extraordinary absence of resonance, rendering it ideal for anchoring even a high-quality two-way system even with its relatively large cone-diameter.
NOTE: All separate Esotec woofers are supplied without grilles.
