Audison

The AP 1 tweeter features a 26 mm diameter emission diaphragm, an acoustic lens designed to compensate for the frequency response within the 10kHz – 13kHz range, a Neodymium REN magnet and extremely small sized dedicated passive crossover.

The AP 4 midbass offers very extended frequency response, both in high and low frequencies, combined with high efficiency and features a 25 mm pure copper voice coil to ensure more balance in mid-high frequency ranges.

AP 6.5 feature a 32 mm pure copper voice coil, for high power handling and outstanding low frequency control. All the woofer don’t employ any filter, to maximize efficiency: the dome profile has been optimised with Klippel R&D Scan Vibrometer to obtain a calibrated mechanical low-pass cut-off frequency. The surround features the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

AP 6.5 Ω2 wooferhas been developed with 2Ω nominal impedance with the purpose of exploiting all the power made available by the AP8.9 bit amplifier capable of 65W into a 2Ω load. To maximize the woofer efficiency achieving 95 dB, a 25 mm diameter 10 mm winding height coil, so a more lightweight coil, has been employed, at the same time also providing a linear excursion 2.8 mm higher than the one of AP 6.5 (4Ω), therefore ensuring high SPL values with minimum distortion even at high listening levels. To extend the woofer’s frequency range down to low frequencies up to 50 Hz a 75 Hz resonance frequency has been chosen, achieving excellent low frequency output even without the use of a subwoofer.

For the vehicles equipped with an 8 inch woofer as standard OEM component, the Audison Technical Department developed the AP 8 which, also thanks to the wide emission surface, provides higher energy in the low frequency range, ensuring excellent performance when the use of a subwoofer is prohibited due to space limitations.

Two way system features AP 1 tweeter and AP 5 Woofer. APCX TW crossover features a two-position level selector providing the ability to adapt its response to its two main applications: +2dB if installed behind the OEM grille, 0dB for an A-pillar installation without additional grilles between the tweeter and the listener.
To ease the installation in OEM placements the woofers are equipped with high current fast-on terminals with double contact on positive and negative poles for high flexibility and quick connection.

Tree way system features AP 1 tweeter, AP 4 MidBass and AP 6.5 Woofer.
APK 163 system deserves special attention; the Audison designers developed a separate crossover dedicated to each speaker, simplifying OEM speaker replacement operation, negating the routing of additional cables through the door, which could void the car warranty. To ease the installation in OEM placements the woofers are equipped with high current fast-on terminals with double contact on positive and negative poles for high flexibility and quick connection.

APK 165 Ω2 system features 2 crossovers dedicated to woofer and tweeter and separated, to ease the installation. APCX WF Ω2 crossover shapes AP 6.5 Ω2’s frequency response to match it optimally with AP 1 tweeter; it also employs a Low ESR inductor, essential to maximize the power transfer to the 2Ω coil. APCX TW Ω2 tweeter crossover, instead, is provided with the Hi-Contour function, to enhance the high frequencies, designed to achieve the correct timbre balance with rich low frequencies guaranteed by the woofer.

APX 4 features a concentric coaxial tweeter: with one single point of sound emission it’s possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.
The 4″ cones surround featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

APX 5 features a concentric coaxial tweeter: with one single point of sound emission it’s possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.
The 5″ cones surround featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

APX 570 features a concentric coaxial tweeter: with one single point of sound emission it’s possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.
The 5×7″ cones surround featuring an exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

The APX 690 featuring an exclusive 40 mm horn loading dome tweeter that contributes to maximize efficiency up to 96dB SPL and an acoustics lens specifically designed and applied to the tweeter to increase dispersion in high frequency range.
To strengthen the emission of very high frequency ranges otherwise affected by off-axis positioning compared to the listening point, the APX 690 featuring a supertweeter.

The new Prima APK 165P two-way loudspeaker system, capable of handling up to 345 W peak, is the ideal combination to fully exploit the power of the AP F8.9 bit or all other Prima amplifiers used in high power configurations. The exclusive AIF technology (Any Install Faceplate) of the AP 1P Tweeter provides the installer with 3 different faceplates for total application versatility and a significant reduction in installation time. The woofer has been designed to perform at its best in OEM placements, combining excellent power handling and efficiency.

Prima AP 2 wide range reproduces the entire range of mid and high frequencies and is perfect for cars of the GM, Ford and Toyota group with 50 mm (2 in.) OEM placements in the dashboard or A-pillar, where it is combined with an elliptical woofer in the car door.

The compact size and excellent electroacoustic parameters make it ideal also to be used as a midrange in 3-way systems, as a surround speaker or as a central channel, housed in OEM placements, where the space requirements would not allow the use of a speaker with a larger diameter.

The advantage of emitting the entire spectrum of frequencies by itself, responsible for creating the virtual stage with absolute phase coherence, ensures a wide acoustic scene concentrated in the upper side of the dashboard. The very low distortion and the lack of crossover point in the mid-high range also provides a natural and pleasant listening experience.

Through careful research and simulation, the R&D team was able to maximize electroacoustic performance for a typical OEM application.

The resonance frequency of 145 Hz, a very low value for a 50 mm (2 in.) loudspeaker, was obtained thanks to the use of a 25 mm (1 in.) voice coil, ensuring a controlled extension at low frequencies for an optimal crossover point with the woofer.

The aluminium cone, in combination with the copper shorting ring that flattens the impedance, allows for the response to be extended up to 20 kHz. The special magnetic group made with double symmetrical Neodymium magnet also contributes to achieve this exceptional extension at high frequencies while maintaining very compact dimensions.

This electroacoustic configuration has led to obtain a particularly wide frequency response, which extends from 150 Hz up to 20 kHz, giving the AP 2 the well-deserved name of wide range.

APK 690 systems are ideal for car models with doors equipped to house elliptical speakers, featuring 6×9 in. woofers and AP 1 tweeter with dedicated crossovers APCX TW 690. The crossovers are ultra-compact to facilitate their installation, and include an attenuation of the tweeter output level for outstanding fine-tuning.The R&D team optimized the electro-acoustic parameters of the new woofers for installation in the car door, respecting all the characteristics of the Prima speakers, such as the compact size of the basket to facilitate installation. The mechanical cut-off of the woofer cone-dust cap system ensures they can be used without a filter, maximizing efficiency to be easily driven by any type of amplifier. The large voice coil ensures high power handling and impeccable control even in the most aggressive dynamic transients. The double Faston connectors with direct link to the tweeter speed up the speakers connection, always ensuring a perfect contact.
