תיאור המוצר

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.


AP 1 Tweeter
1. 26 mm diameter diaphragm combined with a wide-roll surround
provides maximum efficiency and reduced resonance frequency.
2. Acoustic lens designed to compensate for the in-car frequency
response in the 10kHz – 13kHz bandwidth caused by critical OEM
placements.
AP 690 Woofer
1. 25 mm pure copper voice coil, for high power handling and
outstanding low frequency control.
2. Water-repellent treated paper cone, featuring a profile developed
with FEM (Finite Element Method) simulation technology and
optimized with the Klippel R&D Scan Vibrometer.
3. Reduced mounting depth, providing ease of installation in OEM
placements.
4. “Triple Wave” surround profile for maximum excursion linearity.
5. Compact basket, protected by abrasion-resistant and scratchproof coating, the motor affixed with damping epoxy adhesive.
6. High current fast-on terminal with double contact on positive
and negative poles for high flexibility and quick connection.
APCX TW 690 Crossover
1. Optimized for OEM Integration featuring an attenuation switch
(0 dB, +3dB) to tune the in-car response according to different
installation conditions.
2. Supplied with fast-on connectors that eliminate any possible
connection errors.
