In the LUNARE 1 speaker the loading of the four 6 inch midrange drivers is accomplished via an anharmonic resonator, which has the characteristics of a transmission line loading with the additional benefits that the low frequency cutoff is lower than it would be for a normal transmission line of equivalent length. In an anharmonic resonator the geometric modes of the system are detuned in frequency from being harmonic multiples of each other. In particular for an acoustic anharmonic resonator in the form that we are using the fundamental mode is reduced in frequency from what it would be for a straight tube resonator of equivalent length. Our transmission lines have a corner frequency of 120 Hz, which would normally require a line length of over 28 inches, but we are able to achieve the same results in a length of 18 inches. The anharmonicity of our transmission line is accomplished by appropriately applied geometric perturbations along the length of the line.

The bass section of the LUNARE 1 consists of two very high excursion 12 inch woofers per cabinet covering the frequency range from 100 Hz and below. The 12 inch woofers are customized units designed by recognized designer Michael Kelly of Aerial Acoustics and licensed for our use. The drivers have an aluminum cone with a large rubber surround allowing for a maximum peak to peak excursion capability of 2.25 inches with almost 2 inches of that being linear. It has a 3 inch diameter 4 layer voice coil and a 12.5 inch diameter die cast frame. The overall weight of the driver is 35 pounds. Two of these drivers with there substantial excursion capabilities allow each cabinet to produce low frequency SPLs (anechoic with no room gain) of 116 dB at 20 Hz and 120 dB for 30 Hz and above. In a normal situation where there is a stereo pair of the LUNARE 1 speakers another 6 dB can be added to these numbers for the overall SPL developed in the listening enviroment.

The cabinet of the LUNARE 1 is constructed of 1.5 inch mdf for the front baffle and 1.0 inch mdf everywhere else with substantial vertical and horizontal bracing throughout. The profile of the cabinet as viewed from the top is in the shape of a trapezoid with the sides tapering from the front to the back at 9-degree angles. This produces the highly desirable result of the side walls being non-parallel surfaces which suppresses internal acoustic modes within the cabinet. The midrange drivers and tweeters each have their own separate enclosures isolating them from the acoustic energy of the woofers. Heavy walled cylindrical PVC tubes are used for the midrange cavities and the woofers utilize the rest of the cabinet for their enclosure. A 5 inch diameter port flared on both ends is positioned at the top of the cabinet. A port with a diameter this large is required to guarantee that there is no chuffing or wind noise with the substantial amounts of air movement the 12 inch woofers with their 2.25 inch maximum excursion are capable of producing. The port tunes the box to a resonant frequency of 22 Hz giving the Lunare a –3 dB frequency of 20 Hz, with no room gain included.

Front and back panels are three-quarter inch machined aluminum. Special finish options are available for both the cabinet and the metal. For ease of uncrating and placement, the Lunare 1 is shipped with casters attached to the 1.5 inch machined base assembly. These are removeable for replacement with leveling spikes if desired.
