THESIS
The Project
In order to create a system capable of reproducing amazing, first-class Sound, each acoustical
component must abide to the most elevated standards of quality and design.
The Thesis amplifiers offer their best performance when used with speakers designed with the same
philosophy. Throughout the years Thesis has represented a name referenced to the perfection of
electronic design and performance. Today, technological development has enabled us to push the
envelope in terms of the prestigious Thesis tradition. Creating a supreme product in amplification, the
Audison development team has achieved their ambition of reproducing an unparalleled Sound.
Appropriate tuning
Assembling a speaker system imposes choices in which parameters such as personal taste, the
physical installation limits and the acoustic environment of the vehicle itself have to be considered.
Thesis speakers ensure the highest performance with both multi-amplified active systems and with
systems using “passive” crossovers.
Pairing TH speakers with the TH amplifiers intensifies the synergy of products belonging to the same
magnificent project. Therefore, choosing an active multi-amplified system or the use of passive
crossovers is merely a question of personal taste.
The available crossover networks are:
THX 2, for a full range two-way system with TH 1.5 violino and TH 6.5 sax;
THX 3, for a full range three-way system with TH 1.5 violino, TH 3.0 voce and TH 6.5 sax;
THX mh, for a mid to high frequency system with TH 3.0 voce and TH 1.5 violino as part of
a "mixed" multi-way system.
Open design
Each filter is, in actual fact, an “open” design which can be customised in order to obtain the best
acoustic response in any environment.
Extreme customization
A mother board, designed for maximum versatile adaptation, provides the ability for anyone to
customize their own THX crossover.
Designed as a continued project in-progress, it is possible to change and set:
- the power connection mode for BiWiring or when used as a passive multi-amplified
system;
- the output level of every single speaker;
- the cut-off frequency of every single output;
- the filter cut-off slope;
- the Q (quality factor) at the crossover frequency;
- the use of notch filters to adjust the system to the vehicles acoustics.
Audison Thesis Advisor
The THX crossover default configuration has been designed to achieve the highest sound quality
levels. This Advanced Manual offers complete information to fully enjoy their potential.
Each user has at his/her disposal the best support to make the most of the Thesis line expandability
and customization possibilities. Through the “Support” area of the Audison website the user can
interact with the Audison Thesis Advisor to be guided by a professional inside the Audison R&D
Division who will provide him/her with the opportunity to further enhance their crossover.
A mother board, designed for maximum versatile adaptation, provides the ability for the users to
customize their own THX crossover.
