    Audison SR 4.300 – 4 Channel Car Compact High Powered Amplifier 500W

    £419.99 Add to basket

    HIGH POWER IN A COMPACT SIZE

    We are proud to present the renovated SR 4.300 (85 W x 4 @ 4Ω) introduced back in 1988 and constantly updated with the best technologies available.

    Audison_ADT

    The Audison design team, headquartered in the Potenza Picena (Italy), spent a long time planning and perfecting the new SR line, taking full advantage of the features that the most recent amplification devices available today are equipped with. After numerous listening tests in a double-blind configuration on a significant sample of professionals and enthusiasts, the R&D team decided to adopt a new D-class technology called ADT (Audison D-Class Technology) for the whole range, which made it possible to reduce the size of the amplifiers considerably, totally preserving the audio performance that characterize each Audison project.

    EDGELESS DESIGN

    As for the electronics design, the Audison style center has taken care of every aesthetic and functional detail, obtaining a compact amplifier made of extruded aluminium with rounded corners that ease the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often cause of noise and dust accumulation.

    COMPLETE CONTROLS ON UPPER PANEL

    As per tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any type of audio system configuration. The controls, protected by a satin-finish aluminium panel, are located on the amplifier upper panel, to be easily reached from above even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.

    Audison_USS

    Thanks to the integration of Audison USS technology (Universal Speakers Simulator) in the high-level inputs, the SR amplifiers can also be appropriately connected to OEM sources featuring the “speaker load detection” function that monitor the presence of a low-impedance load to enable audio outputs.

    LIMITLESS CONNECTIVITY

    All models are equipped with high-level balanced inputs for connection to the OEM Head Unit speakers output and low RCA level for the after-market ones. When the high level input is used, the ART function (Automatic Remote Turn-On / Off) can be enabled to control the switching on of the amplifiers with the head unit switch-on button.

    In addition, there is a remote IN / OUT socket to allow the control of multiple cascaded amplifiers switch on when required.

    The SR 1.500, SR 4.300 and 4.500 models recreate the PRE-OUT signal by using the Speaker-IN input to interface it with OEM sources only equipped with amplified outputs, allowing the system expansion.

    Hertz MILLE MPX-165.3 PRO – 6.5″ 16.5cm 2-Way Coaxial Speaker 200W

    £275.99 Add to basket

    The coax tweeter concentric to the woofer of the MPX 165 car audio coaxial speakers allows for one single linear-phase emission point, for a natural timbre providing a detailed sound stage. Thanks to the “Center Tuning Duct” geometry, the tweeter resonance frequency is especially low and the employment of damping materials for the inside provides for a linear acoustic emission. The acoustic lens optimizes its off-axis response, which is typical with door installation of coax speakers; besides, the 36 mm diameter woofer generates deep and controlled bass frequencies.
