High-efficiency "Planetarium" systems by AudioKinesis

The new Planetarium systems by AudioKinesis take an innovative, wholistic approach to optimizing the loudspeaker/room interaction. Two different types of main modules are tailored for different room situations, and a common four-piece subwoofer system gives smoother, more pitch-correct bass throughout the room than is possible with conventional low frequency systems.

Planetarium Alpha System (shown above)

The Alpha version of the Planetarium system uses a pair of controlled-pattern monopole main modules that cover the range from 70 Hz on up. The drivers are very high quality prosound types (96 dB, 8 ohms), which have negligible power compression at normal in-home levels. The radiation pattern is exceptionally consistent through the crossover region and on up. The Alpha system is optimized for situations where the main modules must be very placement-flexible.

Planetarium Beta System (shown above)

The Beta version employs the controlled-pattern offset bipole configuration of the Golden Ear Award-winning Dream Makers, but using the higher-efficiency main drivers and advanced bass system of the Planetarium Alpha. The 16-ohm, 96 dB Beta system is optimized for rooms where the main speakers can be placed out from the wall several feet, giving sufficient time delay that the energy from the rear-firing drivers contributes to natural timbre and liveliness, thus better recreating the perception of a live performance.

The Bass System (shown above)

The main obstacles to natural-sounding bass reproduction are the inevitable room interactions - which impose large peaks and dips on the bass response. By using multiple subs spread asymmetrically around the room, each sub will produce a unique peak-and-dip pattern at the listening position. The combined average of these unique peak-and-dip patterns is much smoother than any one of them would be, resulting in more natural-sounding bass with excellent pitch definition. The Planetarium bass system also avoids the subjective slowness of most subwoofer systems by taking room gain into account. Typical in-room extension is to 20 Hz, but the main advantage of this approach is bass quality, not quantity. Not shown is the 1,000 watt shelf-mount bass amplifier, which has a fouth-order lowpass filter continuously variable from 30 Hz to 200 Hz, and a single band of parametric EQ.

Planetarium Alpha and Beta modules available separately; bass system sold separately as “the Swarm version 2.0”. Additional images and information at the link, or you can check out my Inmate Picture Gallery.

Let me know if you have any questions. Thanks for taking a look!
