Car-customized crossover circuit

Acoustic frequency response customization – Sound field – car interior:
Generally, the given acoustic conditions in a vehicle are unfavorable; moreover they are different in each type of car.

The extremely limited interior space, its form and the materials used lead to car-specific deflections for example impairing the sound transmission and its reproduction. Even high quality loudspeakers are compromised in their performance and sound quality if the interior acoustic environment is ignored.

It is entirely dependent on the crossover design to make use of the acoustic properties of the driver. .

Sound image:
Extensive measurement studies yield the decisive parameters for perfect sound. This isn’t simply taking crossover frequencies from a manual, rather it is the sensitive precision work of developing crossover networks, for which no standard calculation formulas exist.

The acoustic customization is performed in two steps:

The »electronic« adaptation:
After installing the loudspeakers in the car, the frequency response in the hearing position is evaluated via a test signal. Hereby frequency response deficiencies are identified. Through a highly developed measuring technique the sound

emission angle of the loudspeakers, possible wiring schemes and component values are tested and determined.

The adaptation through »hearing tests«:
In the end the trained ear is the most sensitive judge of a harmonic sound tuning. The acoustic finetuning of the theoretical calculations and the correction of the residual transmission errors is therefore performed by hearing tests with various types of music.

Sound quality:
High-quality electronic components and a precisely defined network guarantee our customers excellent sound resultsMany tests and positive assessments by the professional press have confirmed this.
