Frequently Asked Questions about Opus 3.5 inch

What are the dimensions of the Opus 3.5" speaker from Quartorigo?

The Opus 3.5" speaker from Quartorigo has a compact size of 3.5 inches, which is equivalent to 8.9 cm. This size makes it ideal for applications where space is a consideration. Especially in complex installations or retrofits in confined areas, this dimension is advantageous. With its precise design and thoughtful layout, it fits into many standard speaker openings and allows for seamless integration. When installing, the exact measurements of the mounting cavities and compatibility with the existing installation dimensions should be taken into account.

What is the power rating of the Opus 3.5" speaker?

The Quartorigo Opus 3.5" speaker offers a power rating of 70 watts RMS. This power allows for clear and rich sound reproduction in a variety of environments. Whether in mobile applications or stationary audio systems, the ability to deliver 70 watts continuously ensures reliable and distortion-free audio playback at various volume levels. This continuous power is ideal for users looking for robust and consistent sound performance without compromising on sound quality.

What impedance does the Quartorigo Opus 3.5" have?

The Opus 3.5" speaker has an impedance of 4 ohms. This impedance is typical for speakers that are compatible with most amplifiers and car radios, allowing for easy integration. During installation, it is important that the impedance of the speaker matches that of the amplifier or audio system to ensure efficient performance and optimal sound quality. A mismatched impedance can lead to unwanted distortion or overloading of the system.

What are the Thiele-Small parameters of the Opus 3.5" speaker?

The Thiele-Small parameters for the Opus 3.5" from Quartorigo include Fs: 96.31Hz, Qms: 2.02, Vas: 1.13L, and Re: 3.50Ω, to name a few. These parameters are crucial for understanding a speaker's performance in enclosures. Fs indicates the resonance frequency, while Vas represents the equivalent air volume. Qms describes the mechanical quality factor, which is relevant for the oscillation behavior. Together, these parameters provide insight into efficiency, frequency response, and optimal enclosure types.

What frequency ranges does the Opus 3.5" cover?

The frequency response of the Opus 3.5" speaker ranges from 150 Hz to 5,000 Hz. This range is ideal for mid frequencies and allows for clearly defined reproduction that supports both speech and instrumental music. The focus on these frequencies makes it particularly suitable for applications such as center channels in multi-channel systems or as part of a two- or three-way system. The precision in this range ensures that sounds are reproduced accurately and in detail.

What is the sensitivity of the Quartorigo Opus 3.5" designed for?

The sensitivity of the Opus 3.5 speaker is 89 dB. A high sensitivity means that the speaker can produce a relatively high volume even with a low input signal. This is particularly advantageous in scenarios where high audio performance is desired with minimal amplifier use. This feature can also help save energy and increase the overall efficiency of the audio system, especially in energy-limited applications.

What type of diaphragm material does the Opus 3.5" speaker use?

The Quartorigo Opus 3.5" uses paper as the diaphragm material. This choice of material is known for its acoustic properties, which support natural and warm sound reproduction. Paper diaphragms can operate with low resonance and provide high damping for unwanted vibrations. The lightness of the material also ensures a quick response and detailed sound resolution. It is ideal for applications that require authenticity and a balanced sound characteristic.

How do you install the Quartorigo Opus 3.5" speaker?

When installing the Opus 3.5" speaker, the dimensions of 3.5 inches or 8.9 cm should be considered to ensure compatibility with the mounting cavities. The installation requires precise drilling and ensuring that the magnet and voice coil arrangement can operate unobstructed. It is important to pay attention to polarity to avoid phase cancellations and to properly insulate all electrical connections to ensure that the speaker operates optimally and delivers maximum performance.

What types of magnet material are used in the Opus 3.5"?

The Quartorigo Opus 3.5" speaker uses ferrite as the magnet material. Ferrite magnets are known for their durability and magnetic strength, which remains stable over a long period. The use of ferrite contributes to the stability of sound reproduction at different volume levels and provides consistent magnetic attraction for the voice coil. Particularly in applications that require long lifespan and continuous performance, ferrite is an excellent choice of material.

What is the Z-Max value of the Quartorigo Opus 3.5"?

The Z-Max value of the Opus 3.5" is 10.44 Ω. This point is crucial for the impedance peak characteristic at certain frequencies and plays an important role in tuning crossovers and system calculations. Knowledge of Z-Max allows for calibrating crossovers to operate most efficiently and ensures that transitions within a speaker system remain seamless and harmonious. This is especially important for optimal operation of holistic sound systems.
