audison Prima AP 4 Mitteltöner Set (100 mm)
Speaker systems developed using the same performance targets as the Prima amplifiers. Astonishing efficiency, fundamental to an OEM upgrade speaker, in conjunction with the natural sound and high power handling of a premium quality speaker. The coax models tout the maximum in technological expression: a concentric tweeter with acoustic lens correction combined with a pulp cone and a 32 mm (1.25 in.) voice coil. The high power handling and consequent bass articulation, along with dispersion and phase consistency in the high frequency range, provide the ability to achieve the performance of a competent 2-way system in those cars where this type of system is not feasible due to physical restraints.
With the Prima speaker range, different solutions have been introduced to
simplify, to the maximum extent, OEM Integration and achieve a result capable of
satisfying the Audison quality criteria. The electro-acoustic designers focused
their attention on those drivers dedicated in reproducing the whole audio range
the coaxial, as these are those most critical in reconstructing the sound stage
and so in recreating the "live" effect in a Car Audio system. By using advanced
technologies such as Finite Element Method (FEM) modelling, as well as a
prolonged "Voicing" phase, consisting of in-car listening sessions, it has been
decided to adopt a concentric tweeter within the woofer, providing one single
point of emission. This typology of speaker ensures that the musical signal is
reproduced with high linearity of acoustic phase; therefore the listener
perceives it as being disarmingly natural. In order to control dispersion of the
high frequency range, the concentric tweeter features an acoustic lens
specifically designed to ensure an extremely linear frequency response when
installed in the door, thus entirely off-axis. The combination of such build
choices offer the possibility to achieve performance and sound quality
comparable to a two-way system for those vehicles prohibiting this type of
On top of this, a believable acoustic sound stage is projected towards the listener. The concentric tweeter also provides the ability to mount the speakers in extreme locations. As an example, in installations where the tweeter of a typical coaxial driver protrudes and may come in contact with the OEM door panel/grille, the Prima line makes the installation simple and reliable. It was during the aforementioned "Voicing" phase that the Audison designers decided to employ a 32 mm pure copper voice coil for the coax woofers; an unusual choice from a technical and cost standpoint for this market range where most competitive product employs a 25 mm coil. The reasons behind that choice can be found in the will to respect the two main goals of this project: high power handling and maximum efficiency. In fact, combined with an amplifier, the 32mm coil ensures musical reproduction void of compression, especially during musical peaks where the motor assembly has to withstand mechanical and thermal stress. The efficiency has been maximised by eliminating low pass crossover components for the woofer: even just a simple filter inductor in series with the woofer, due to the resistance of its winding, introduces a loss which in turn lowers efficiency and sound pressure level. By not employing any type of filter, our designers had to optimize the cone profile in each model using the Klippel R&D Scan Vibrometer to obtain a calibrated "mechanical" low-pass cut-off frequency, therefore achieving a frequency response close to that of a filtered woofer! The result of this exhausting work of research gave life to a series of speakers capable of handling noticeable power combined with high efficiency and a balanced timbre.
AP 4AP 4 is the system midbass: it inherits the triple wave suspension from the larger diameter components, and is capable of providing excellent response on bass frequencies down to the 80Hz range. During listening sessions of this component, it has been decided to employ a 25 mm coil, as it ensures more balance in the mid-high range and most of all, provides the ability to extend the frequency response up to 7,5 kHz with a remarkable 93dB efficiency. With Prima speaker, the Audison R&D team had a difficult target: combine the strict requirements of OEM Integration with the Audison audio quality. The target was centered through an exhaustive research combined with long listening sessions that brought the speakers to a level of performance that was thought impossible to obtain in OEM Integration.
