Taiyo International will release the floor speaker "Tesseract" made by Avalon Acoustics. It is completely made-to-order and the price is 45 million yen as a pair.
A floor type speaker equipped with a 2 cm diameter tweeter equipped with a "diamond underhang voice coil", a 11.5 cm diameter midrange equipped with a ceramic honeycomb cone, a 28 cm diameter midbase, and four 38 cm woofers. The product name, Tesseract, means "four-dimensional cube" and says, "A four-dimensional hyper three-dimensional, high-dimensional object is embodied in a three-dimensional space."
The ceramic honeycomb cone mid-base driver adopts a high BI magnetic structure in the underhang gap, and the midrange and tweeters adopt a spiral magnetic structure to "embody the lowest transient ripple."
The housing aims to "acoustically eliminate the self-assertive structure of large speakers," with consideration given to the sound that the playback sound reflects from the walls and ceiling of the room and reaches the speaker. , Stealth cabinets can acoustically disappear from the space."
The network design is based on the classic all-pass phase network to prevent phase errors in crossover. Avalon Acoustics' unique network uses a minimum number of ripple waves to maintain phase consistency at crossover frequencies.
In addition, an analog anti-aliasing filter removes excess bands from overlapping waveform sources. The noise outside the stopband is limited so that moire and cloudy bleeding do not occur at the image edges.
A 2.5kW amplifier is directly connected to the transmission line in the speaker to achieve rich bass. The maximum level and transient speed can be adjusted with a switch.
Reproduction frequency band is 16Hz to 50kHz, efficiency is 93.5dB, noise floor level is 68dB or less (relative to the maximum level), 76dB (typical value). Impedance is 6Ω (4Ω minimum value/80Hz). Recommended amplifier output is 15~500W. The external dimensions are 740 x 820 x 2,210 mm (width x depth x height), and the weight is 1 unit 375 kg (shipping weight 908 kg/2 units).
Each unit is placed in a uniquely shaped housing
