A SUBWOOFER SYSTEM FOR GRADIENT REVOLUTION, the QUAD ESL-57 and HARBETH and SIMILAR QUALITY BOOK SHELF SPEAKERS.


Independent Finnish Loudspeaker Manufacturer is back with with new range of specially tuned dipole subwoofers for Electrostatic speakers. All new scale of product for various implementations for those, who like their ESL’s a bit more bassy

Gradient SW-S is based on the same dipole technique as the previous model, SW-57, which physically also served as a standard for Quad ESL-57 speaker. Each unit of the new system includes two 12" long throw custom made woofers which increases the bass capacity and extends the lower cutoff frequency to 20Hz.


"If you have a better monitor than the Harbeth you may want to consider adding the Gradient SMARTBass.
For demonstration purposes, a small Harbeth P3ESR monitor was placed on top of the SW-S units. After listening to some of their music selections and comparing the Harbeth alone with the Harbeth combined with the SW-S, I asked Tim Ryan, the host, to play my Chinese drum cut and repeat the comparison. It quickly grabbed the attention of the people in the room, and even more started piling in".

Gradient SW-S is based on the same dipole technique as the previous model SW-57 which physically also served as a stand. Each unit of the new system includes two 12" long throw custom made woofers which increases the bass capacity and extends the lower cutoff frequency to 20Hz.

 
The main benefit of the new system is the possibility to rotate the bass sections to direct the dipole bass radiation. This helps to obtain the most uncolored bass reproduction with minimum effects of standing waves in the listening room.
For playback one needs two pieces of SW-S units, one for each channel, an electronic crossover and two power amplifiers, one for the ESLs and another for the subwoofers. Together with the Gradient High End crossover this system will reach a new level of performance.
 
The units are available with solid cherry wood parts or ash, black or white painted ash plywood parts. Cloth options are black, brown, white or light gray. In addition to the standard finishes, Gradient SW-S may be customized with a huge variety of options. In total 20 different high quality fabrics and multiple real wood veneers allow personalized speakers for every taste.
