Hiifonics MRW104 - 25cm subwoofer

MRW104

The optimal application for the  two  Mercury subwoofers MRW104 and MRW84 is in the bass reflex or bandpass range. Since the woofers require relatively small volumes, the use of multiple subwoofers is recommended. For example, an MRW84 in a 20-liter bass reflex enclosure already achieves an extremely low lower cutoff frequency (-3 dB) of 32 Hz! With minimal loss of low bass, but all the more dynamics and dry bass, the subs are also highly recommended for use in small closed enclosures.

The quality of   the Mercury subwoofers is exceptional: with their perforated steel baskets in HiFonics design, they not only make a visual statement, but the selection of components used is also impressive: molded paper cones,  durable rubber surrounds, and robust spiders are the ingredients. Even the small MRW84 with a diameter of 20 cm, like its big brother MRW104, already features a very large 50 mm voice coil. Visually, both woofers impress with a chrome-plated basket and magnet boot, so that they also look particularly good in inverted installations such as the Mercury boxes with a view of the basket.
