THESIS: BEYOND THE ABSOLUTE
TH 77 SAX
TH 77 SAX Coaxial | 300 W Peak Power | 196 mm (7.7 in.) | 4 ohm
TH 77 SAX brings the Thesis reference to the zones where space is measured. The same 1.5 in. tweeter as the rest of the collection, extended to 40 kHz and certified Hi-Res Audio, in a 7.7 in. coaxial engineered for salt, ultraviolet light and vibration. The double-wave grille disperses sound across open decks while deflecting water, and integrated RGB CCT lighting makes the speaker part of the design of the vessel.

Technologies
The full resolution of the recording, at sea.
Certification issued by the Japan Audio Society under IEC 60268-5 test conditions, covering the complete system from source to speaker. Frequency response extended to 40 kHz, one octave beyond the market standard in the high frequencies. Audison is the only brand in the marine industry to offer complete certified systems.
Every curve has a job.
The functional signature of the collection. Its geometry widens sound dispersion in an environment with no reflecting surfaces and, with the same shape, deflects water and reduces salt accumulation. Engineering, not styling.
Built to outlast the sea, season after season.
IP65 marine-grade basket, Deutsch connectors, water-jet testing, 1,000 hours of ASTM-B117 salt fog validation and UV-inhibited materials. Protection engineered into the project from the beginning, beyond industry practice.
Part of the lighting design, not an obstacle to it.
Integrated 12 Vdc RGB CCT LED lighting with tunable white, so each speaker adapts to the ambiance on board, from a working deck at dawn to dinner under way.
Exceptional dynamics, in less space.
High magnetic flux density for outstanding dynamic performance with reduced size and weight, matched to an optimised thermal circuit that holds performance at the highest power peaks and eliminates dynamic compression.
