Teti is a visionary project, crazy and ambitious, but strong, born to give a different sense to the usual speaker. More than three years of hard work have gone into drawing, testing and prototyping to achieve this result. Design has sought technical solutions that could give a new way to visualize and enjoy music. Quality of sound reproduction, cleanliness, detail, naturalness, depth, stage and ease of listening are the characteristics sought and put to use in this particular speaker. Solutions and technical choices have necessarily led to an extremely complex construction of the interior of the cabinet, the chambers of agreement. The complexity of this music instrument was designed and then finalized to give extreme ease of placement and listening, just pleasure for the eyes and ears.
