Aerial Acoustics

Cabinet
A loudspeaker cabinet must provide the right air volume for the drivers while not affecting in even the smallest way the pure sound from the drivers. Ideally the cabinet should disappear sonically.

The Aerial Acoustics Model 7T is a good example. It uses 9 layers of 3 mm thin MDF impregnated with wet glue, then forced into a geometrically strong curved shape under 20 tons of pressure and held for 48 hours until the glue is hard. This construction traps the strong bending forces in the curved wood panel, stiffening them and improving their physical properties. Beyond this, the hardened glue saturating the thin laminations makes a wood/glue sandwich that is very hard and inert.

In addition extensive interlocking bracing runs side-to-side, front-to-back and top-to-bottom to naturally cancel the opposing vibrations from opposite walls. Separate front baffles are attached to the front of the cabinet with a soft damping glue to interrupt the energy flow from the drivers to the cabinet walls while increasing the mass of the front walls, further reducing even the smallest sounds from the cabinet. New Zealand long-fiber natural wool insulation is used in critical areas because of its superior sound quality.

German Danzer veneers are used on the wood finished cabinets. 10 layers of hard, high-density polyester are applied with hand-polishing between each layer. The painted finishes utilize high quality automotive paints. The gracefully curved grilles are acoustically open and mounted securely using 8 pairs of strong hidden Neodymium magnets.

Drivers
A loudspeaker systems drivers are the origin of the sound. They determine the upper limit to the sound quality of a speaker. Their sound quality must be as natural, detailed and perfect as possible without any unnatural artifacts.

Aerial Acoustics uses custom-designed proprietary drivers built specifically for Aerial primarily in Denmark. All acoustic parameters including magnets, voice coils, cone materials, glues and other materials are fully optimized for application in each Aerial speaker model to provide linear performance beyond their range of use. Drivers designed this way increase the maximum sound quality possible from a system.

One example is the larger magnet and coil structures used in Aerial drivers. We use longer coils allow than iss normal. This is to insure that the voicing of the speaker will not change when the playing volume is increased. It also extends dynamics without compression and lowers distortion. However this requires that larger magnet systems be used to maintain sensitivity. Voice coil formers are either titanium or glass fiber. All Aerial custom woofers are designed this way.

Crossover
The function of a crossover is to seamlessly blend the individual drivers to produce sound that is natural, delicate, dynamic, transparent and seems to come from a single driver.

Aerial uses high quality metalized film capacitors and air core coils throughout the midrange and treble sections, while larger bass coils use low hysteresis nickel-steel laminations. Silver solder and Teflon insulated 99.99% high purity copper wiring is used. Crossover slopes are true acoustic 24 dB/oct.

Assembly, Testing, Listening
Since its beginnings in 1989, Aerial Acoustics has been offering high performance and quality, long-term listenability, and excellent value in high-end loudspeakers. By taking advantage of advances in materials, construction techniques, and acoustic analysis, Aerial has continued to improve its products over the years. This steady improvement has resulted in the current line, Aerial’s finest expression to date of design, finish, and sonic fidelity.

All Aerial Acoustics loudspeakers are designed, engineered and assembled in Massachusetts, USA.
