Elaboration creates problems, simplicity and purity create perfection.
The pedestrian looks of the Audio Note loudspeakers are well calculated. The front baffle dimensions and depth of the cabinet are an integral part of the wave launch support and controlled defraction characteristics pioneered by Peter Snell in the 1970's. Smaller, narrow baffles, like those found in most of today's "fashion victim" designs currently masquerading as quality loudspeakers achieve nothing other than to compromise midrange frequency and tonal colourations.
Speakers with narrow baffles demonstrate a characteristic nasality and thinness in the critical vocal region with unrealistic/unnatural image placement. This is due to peaky response and loss of low level information. Spatial effects become distinctly "hi-fi" and not faithful to real musical presentation.
The The AN-K is a bookshelf-sized loudspeaker capable of a bandwidth from 50 Hz to 20 Hz (-6 dB) with an efficiency of around 90 dB/m.
Careful pair matching, first by drive unit selection, secondly by pairing drive units with suitable characteristics to each other, and then finally by individually adjusting each speaker's curve, under dynamic conditions to a master curve.
The AN-K cabinet is made from materials that compliment the workings of the chosen drive units, where we, instead of trying to damp the resonances in the cabinet, place them in frequency bands where they aid and enhance the drive unit's work. This novel and quite difficult method helps to ensure maximum efficiency and dynamic behaviour.
