This pair of Avantone Pro MixCube Active Black Mini Reference Monitor is a professional studio reference monitors specifically tailored to produce the useful musical range of 90Hz to 17kHz. In today's world of high definition media, it is still necessary to mix music that translates and sounds as defined on lo-fi speakers such as laptops and smartphones, as well as hi-fi full-range HD audio systems. The MixCubes provide audio engineers with accurate and detailed mid-frequency referencing, leaving the larger 2-way and 3-way monitoring systems to bass and high-frequency referencing. 
 
The Cabinet
The original 5C Sound Cubes™ were made of ½” particleboard covered with a glue-on wood grain contact paper. We chose to use thicker, denser MDF board because of its high rigidity and inherent low-resonance characteristics. We started with a 165mm (6 1/2") sealed cube design with radiused edges. We then chose an elegant Polyurethane high gloss “RETRO-CREAM” finish. The originals had either screws or on later models plastic binding posts mounted on a recessed plastic cup. We upgraded to high-end nickel plated, machined solid metal binding posts (Dual banana spacing) mounted on a black anodized ,milled and silk-screened aluminum terminal plate. Next we added a 7mm thick neoprene pad embedded into the base of the cabinet to serve as a skid-resistant acoustic isolator. Additionally, for creative mounting situations, we recessed an industry standard 5/8”-27 mic stand mount into the base.
 
The Driver
The originals were a basic 5” stamped frame design. We designed a proprietary 5.25” die cast aluminum frame driver/cone assembly to exceed the performance of the originals. The mounting bezel is then polished for an elegant appearance. The paper cone, chosen for its musical character, is custom designed & crafted using the finest New Zealand pulp with mica fibers added for lighter weight & rigidity. The cloth surround is made in Japan to exacting uniform thickness tolerances. The Top Plate and T-Yoke of driver are made of Sumitomo 1008 low carbon steel enabling the highest modeled flux density in the gap. The magnets are Y- 40 GRADE (MIL-SPEC) yielding a 43oz. High Power-low distortion motor structure.
 
The Amplifier
We designed the amp module from the ground up to be a true professional-grade amplifier. It incorporates “overkill” concepts in component selection as well as safety. The result is a “no-compromise” amp with robust headroom characteristics that will rival the performance of much higher priced studio rack mount amps.
