The precise dimensions ensure that the speaker fits optimally in the designated opening, minimizing vibrations and noise.

What are the key TS parameters of the Opus 8"?

The Thiele-Small parameters (TS) of the Quartorigo Opus 8" provide deeper insights into the technical capabilities of the speaker. The resonance frequency (Fs) is 39.8Hz, indicating deep bass capabilities. The mechanical quality factor (Qms) is 5.462 and the electrical quality factor (Qes) is 1.0047, while the total quality factor (Qts) is 0.85, indicating balanced performance in various enclosures. The effective displacement area (Sd) is 0.0214m² and with a moving mass (Mms) of 27.38g, the speaker offers remarkable sound performance. These parameters help to optimally tune the speaker for specific audio needs.

What materials are used in the Opus 8"?

The Quartorigo Opus 8" speaker uses a combination of proven materials to ensure optimal performance. The diaphragm is made of paper, known for its speed and precise responsiveness, achieving transparent and even sound reproduction. The magnetic material is neodymium, a rare earth element known for its strong magnetic performance. This allows for a compact design while maintaining high performance. With a voice coil diameter of 38 mm, it provides perfect conditions for powerful sound reproduction with minimal distortion at high volumes.

What does the frequency response of the Quartorigo Opus 8" look like?

The frequency response of the Quartorigo Opus 8" ranges from 30 Hz to 3,000 Hz. This bandwidth allows for effective coverage of both low and mid frequencies, making it ideal for a variety of music genres. The speaker delivers impressive bass reproduction at 30 Hz, capable of rendering deep bass with clarity and precision. At the upper end, the frequency response reaches 3,000 Hz, which ensures a clear representation of voices and instruments in the mid-frequency spectrum. This results in a balanced sound profile suitable for both demanding and everyday audio playback.

What power does the Opus 8" speaker provide?

The Quartorigo Opus 8" speaker offers an RMS power of 120 watts. This power ensures impressive sound reproduction even at high volumes. The recommended impedance of the speaker is 4 Ω, making it compatible with many amplifiers. With a sensitivity of 89 dB, it is designed to effectively convert even quiet signals into audible sound. These features make it ideal for use in vehicles that require dynamic and powerful audio performance. Especially if you enjoy listening to music loudly, this speaker provides the necessary power to enhance your listening experience.

Are technical adjustments necessary for the installation of the Opus 8"?

For the installation of the Quartorigo Opus 8", technical adjustments may be necessary depending on the type of vehicle. The dimensions of the speaker are 20 cm, so it is important to check compatibility with the existing speaker openings in the vehicle. The installation depth may play a role in some vehicle models, so it is always advisable to clarify the available space beforehand. The wiring should also be adjusted to make the best use of the normal impedance of 4 Ω. With careful preparation and the right adjustments, the installation can be carried out without major issues.

Can I use the Opus 8" speaker in my car?

The Quartorigo Opus 8" speaker is suitable for installation in various car models. Thanks to the standardized dimensions of 20 cm, it can be integrated into many conventional 8-inch speaker positions. When installing, you should pay attention to the installation depth and the existing mounting points to ensure smooth integration. The use in a car primarily depends on the speaker cutouts and the power consumption of the existing audio system. The universal impedance of 4 Ω greatly facilitates integration, allowing you to install the speaker in most vehicles that operate with this impedance.

What does a sensitivity of 89 dB mean for the Opus 8"?

The sensitivity of 89 dB for the Opus 8" speaker means that this speaker is capable of producing sufficient volume even at low power. The unit dB SPL (Decibel Sound Pressure Level) indicates how loud a speaker reproduces a sound when powered with one watt and measured at one meter away. A sensitivity of 89 dB is an indicator of an efficient speaker that is suitable for a wider range of amplifiers. This is particularly advantageous if you prefer high performance at low wattages, which also provides flexibility in amplifier selection.

Why is neodymium advantageous in the magnet material of the Opus 8"?

The use of neodymium in the magnet material of the Opus 8" speaker offers several advantages. Neodymium is a strong rare-earth material that outperforms conventional magnets in terms of flux density. The result is a smaller, lighter magnet that still provides the same strength as larger iron magnets. This allows for a compact design of the speaker, saving space in the vehicle and making installation easier. At the same time, neodymium ensures optimized efficiency in driving the speaker, which is reflected in improved audio reproduction. The combination of efficiency and space-saving makes neodymium a top choice for the Opus 8" speaker.

How does the voice coil in the Opus 8" affect sound quality?

The voice coil of the Opus 8", with a diameter of 38 mm, plays a crucial role in the sound quality of the speaker. A larger voice coil can dissipate heat better, improving durability and the appropriate tones. This contributes to clean and clear audio reproduction, even at high volumes. Additionally, the maximum displacement of the diaphragm is optimized, which can lead to lower distortion at low frequencies. As the volume increases, precision in the audio range is maintained. The processed coil structure allows the speaker to deliver excellent sound fidelity, which is particularly evident with demanding music tracks.
