Universal ISU165

The sensitivity of the Universal ISU165 Speaker from Focal is 93 dB at 2.83V/1m. This high sensitivity means that the speaker is capable of producing impressively clear and loud sound, even with minimal power loss. This is particularly advantageous in applications where you want to draw maximum efficiency from the available energy. Sensitivity is often measured in decibels (dB) for speakers, indicating the volume a speaker produces at a given input power. With 93 dB, this speaker is among the more efficient models and is ideal for use in cars to significantly enhance your music enjoyment.

The ISU165 Speaker Set from Focal offers a wide frequency response from 60 Hz to 21 kHz. This range is crucial as it represents the speaker's ability to reproduce different tones. Low frequencies, such as those produced by a Subwoofer, start at around 60 Hz, meaning the ISU165 is capable of representing both low and high tones up to 21 kHz. This allows for a balanced sound experience where both deep bass notes and the high frequencies of instruments and voices are reproduced clearly and in detail.

The maximum load capacity of the Focal Universal ISU165 is 140 watts. This specification is relevant when you install the speaker in a power system, as it represents the maximum power the speaker can handle over a short period without damage. Properly matching the amplifier power with the maximum load capacity ensures that you can achieve the best possible performance without distortion or damage. This load capacity also indicates that the Speaker Set is capable of delivering clear and rich sound even at high volumes.

The Universal ISU165 Speaker Set from Focal has a mounting diameter of 142.6 mm and a mounting depth of 48.4 mm. These dimensions are crucial when planning the installation in various vehicle types, as they determine compatibility with the mounting locations in car doors or dashboards. With a compact mounting depth, the speaker offers flexibility and fits more easily into limited spaces, which can be advantageous in many modern vehicle designs. Therefore, before installation, you should ensure that the installation location supports the specified dimensions.

The woofer of the Focal ISU165 speaker uses a Polyglass diaphragm with a diameter of 165 mm. This design combines the stiffness of fiberglass with the lightness of polymers, resulting in increased efficiency in sound conversion. Polyglass provides an excellent balance between rigid resonance control and smooth sound reproduction, which is particularly important for delivering deep frequencies clearly and powerfully. The choice of materials affects not only sound quality but also the durability and resilience of the speaker systems against environmental factors.

The Universal ISU165 speaker from Focal has a nominal impedance of 4 Ohms. This impedance is crucial for ensuring compatibility with a variety of amplifiers and optimizing the speaker's performance. In most vehicles, the audio system operates with 4 Ohm speakers, making the ISU165 an excellent choice for retrofitting or upgrading existing systems. An impedance of 4 Ohms ensures efficient power supply and allows for effective use of the available amplifier power, which is especially important in loud environments.

The Universal ISU165 from Focal offers a nominal power handling of 70 Wrms and a maximum power handling of 140 W. These performance specifications are crucial for planning an audio system, as they indicate how much power the speaker can handle continuously and at peak levels without damage. The sensitivity of the speaker is 93 dB at 2.83V/1m, indicating excellent efficiency for producing loud and clear sounds with low to medium amplifier power. This combination of power handling and sensitivity makes the ISU165 an ideal candidate for sound enthusiasts.

The installation of the Universal ISU165 Speaker Set from Focal is relatively easy to implement due to its compact dimensions. With a mounting diameter of 142.6 mm and a mounting depth of 48.4 mm, you can install the speaker in most standard speaker cutouts. Make sure to measure the depth of the installation space to avoid complications due to lack of space. Don't forget to use any necessary seals to minimize resonances and maximize sound quality. The installation can be carried out by yourself with suitable tools and basic knowledge in vehicle modification.

The Focal ISU165 is designed as a universal speaker set and can be installed in a variety of vehicles. The mounting diameter of 142.6 mm and the mounting depth of 48.4 mm allow installation in many common car brands and models. It is important to check compatibility with specific model requirements before purchasing, especially regarding the installation spaces in doors or the dashboard. The flexible dimensions create diverse installation options and provide an ideal solution for those looking to upgrade their vehicle's sound.

The Polyglass membrane of the Focal ISU165 offers outstanding advantages in terms of sound performance and material properties. The structure combines the lightness of polymer materials with the rigidity of fiberglass, resulting in precise sound reproduction. Sound fidelity, especially at low frequencies, is improved as the material minimizes resonances and dampens unwanted vibrations. This means a rich and detailed music playback with clear bass definition for you. The durability of the membrane also ensures consistent performance under varying environmental conditions, which is important for operation and reliability in the car.
