THE RIDDLE

Listening to music on small-sized systems is a reasonable and quite understandable preference, given that they are easily installed in many venues.

Although the compromises required make this sort of design almost impossible, Sonnet offers a solution to bypass the Laws of Physics. To integrate this strict definition, while we can safely say that we perform miracles to do our best at Chario Loudspeakers, we are nonetheless proud to say that we are strangers to miraculous designs.

Two-way bookshelf systems usually place the tweeter in the uppermost region of the speaker’s cabinet.If the designer is also aiming for synchronization of the two transducers, the plinth must be given a suitable back tilt. Sonnet inverts this principle by affixing the tweeter below. Hence, the cabinet should be tilted forwards.
