Avantone Passive MixCube Pair – Black


Avantone Passive (pair) Black MixCubes

The Avantone MixCubes are shielded, full-range mini reference monitors.

Their design is inspired by the legacy from the 5C Sound Cubes utilized in virtually all-major studios for the last Twenty five years.

Engineering Objective
To construct a complete range, rugged, mini-reference monitor to replace the older, aging, 5C Sound Cubes that are still being used worldwide, while offering a better, more linear frequency response. A complete year was spent studying all versions & revisions from the famous little 5C Sound Cubes. Research says there have been several driver versions released over the years with widely varying frequency response characteristics. We find the smoothest, most linear, full-range form of those 5C models for our testing benchmark. Next we analyzed their response characteristics in an anechoic chamber and proceeded to implement design upgrades. Realizing the significance of replacing a top “industry-standard reference monitor” we began by replicating its basic size, function, and sonic character.


We desired to take it up a notch though…

First, we addressed
your cabinet Design… The initial 5C Sound Cubes were created 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 having a 165mm (6 1/2″) sealed cube design with radiused edges. We then chose a stylish Polyurethane glossy “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) installed on a black anodized ,milled and silk-screened aluminum terminal plate. Next we added a 7mm thick neoprene pad embedded in to the base of the cabinet for everyone like a skid-resistant acoustic isolator. Additionally, for creative mounting situations, we recessed a business standard 5/8”-27 mic stand mount into the base.

Second, We addressed the motive force design… 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 will be polished for an elegant appearance. The paper cone, chosen because of its musical character, is custom-designed & crafted using the finest Nz pulp with mica fibers added for lighter weight & rigidity. The material surround is created in Japan to exacting uniform thickness tolerances. The very best Plate and T-Yoke of driver are made of Sumitomo 1008 low carbon steel enabling the highest modeled flux density within the gap. The magnets are Y- 40 GRADE (MIL-SPEC) yielding a 43oz. High Power-low distortion motor structure.

Performance Objective
Studios primarily use 2-way & 3-way larger monitors
designed to represent a wide range reference viewpoint at higher listening levels. However, within this newly developing age of High Definition Audio, there is still a necessity to also hear what your mix will sound like when played back over small “bass-challenged” systems for example televisions, clock radios, computers, car stereos, iPod docking stations, etc. It is important to make mixing judgments based partially on listening to reference monitors that will not impart tonal anomalies caused by crossovers or inferior full range drivers. Particular attention is definitely paid towards the critical mid-range vocal/guitar/keyboard areas. This is where having a full-range monitor without a crossover is really revealing. Ten months of R&D comparative listening & tweaking went into the voicing from the Avantone MixCubes. The result is a very smooth sounding, full-range upgrade from the original 5C Sound Cubes. Listening tests demonstrate that the MixCubes have a smooth, more open, transparent top end response with extended bass while maintaining their basic original character.

Amplification & Wiring
Recommended power rating is 50-200 watts of solid state power or 10-100 watts of tube power. It
is advisable to use a high quality studio-grade power amplifier. The metal binding posts around the rear of the speaker can accept bare wire, spade lugs, or single or dual banana plugs. It is advisable to use 12 -16 AWG wire for runs more than 6 feet

When positioning the Avantone MixCubes on stands or console bridges
it is best to keep them at ear level and slightly angled in towards the engineer. Being that they are shielded it is ok to place them near a CRT video monitor or TV without causing any problems. The underside mic stand mounts will even allow you creative positioning options in unusual studio playback situations.
