Introduction
Congratulations on making the investment in Teresonic speakers that will enable the
musical reality of a concert hall or a jazz club transferred to your listening room.
eresonic Audio speakers are designed to produce the most natural sound of exceptional clarity and
levels of detail, neutrality and stereo imaging that are beyond anything else in their category. That is
accomplished using unique and very advanced acoustic design, finest components and materials
available, and by avoiding every unnecessary component or gimmick that can introduce sound
coloration, interference or distortion – leading to musical reality of a concert hall or a jazz club transferred to
your listening room.
New life for your music yet perfectly natural
Every sound source in nature is “punctual” radiating sound waves around them – whether it’s a violin, a
trumpet, or a human voice. Teresonic speakers follow that basic design rule of the Nature. Multi-driver designs
introduce multiple interfering sound sources (speaker drivers in the cabinet) which lead to complex and
unpredictable cancellations and reinforcements between sound waves – leading to sound colorations and
distortions. Teresonic one-way speaker design using full range high-efficiency drivers, provides natural sound
with a wealth of detail, exceptional dynamic range and a sense of musical “livens” that you don’t often hear
elsewhere.
The challenge is to make speakers that we can call transcendental - something that breaks boundaries and
creates emotion, but keeping sound natural and intact, as it was in the concert hall or recording studio.
Teresonic speakers operate legendary Lowther full-range speakers without any electrical components such as
filters or crossovers between the amplifiers and the speakers. Conventional designs put a crossover in the mid-
range to split the signal to the bass driver and the tweeter. This is exactly the region where our hearing is most
sensitive. These crossovers introduce phase and balance problems that cause deterioration in detail,
transparency and imaging. Even worse, most speakers go from a cone driver for the bass to a tweeter with
totally different sonic characteristics, such as a dome or ribbon tweeter, for the treble.
The ability of the Teresonic speakers to speak across the full frequency spectrum with one voice, and with such
speed and lack of coloration, makes them seem all the more electrostatic. In the end, however, Teresonic
speakers will play much louder than all except the largest electrostatic speakers and they will best any
electrostatics in bass power and dynamic wallop. You can hit these speakers with hard transients and they not
