En underbar högtalare. Oj vad den spelar. Och den upplevs inte alls så stor som man skulle kunna tro.

Egenskaper

Doulbe Bass is a six driver 4-way vented design floorstanding loudspeaker. Since the port is on the both sides of bottom of the speaker, it can be placed closer to the front wall compared to many other full range speakers without bass bloat because of a rear port. This speaker packs reference level parts quality and design. The woofer and midrange-woofer are 12 and 8 inches wide with aluminum frames. In addition, they are composed of a sandwich of non-woven carbon fiber with a 3-inch and 2-inch copper clad aluminum voice coil with flat wire and a special Ferrite magnet system with a Faraday ring and demodulation coil. The two midrange-treble are 5-inch long air motion transformers. The high frequency driver is a 3-inch ribbon tweeter. Located behind the Double Bass is a 4-inch ribbon tweeter for ambience and to increase the depth of the soundstage. Crossover parts use high quality MKP capacitors, high purified OFC inductors and military grade metal oxide film resistors. Finally, the Double Bass comes with double WBT connectors for bi-wiring. Double Bass’s appearance is modeled off of a musical instrument and aesthetically looks like a piece of art sculpture. By designing it with polygonal, non-equilateral shapes and sides, the parallel surfaces are eliminated which reduces standing waves and diffraction. The narrow “neck” of the enclosure also decreases diffraction for the midrange and high frequency drivers. The front baffle is a matte black color with seven “strings” running down the lower half of the speaker. Since the port is on the both sides of bottom of the speaker, it can be placed closer to the front wall compared to many other full range speakers without bass bloat because of a rear port.
