Frequently Asked Questions about Rhapsodis 3.5 inch

What are the dimensions and key features of the Rhapsodis 3.5 by Quartorigo?

The Rhapsodis 3.5" by Quartorigo features compact dimensions of 3.5 inches or 8.9 cm. This size is ideal for tight installation spaces, especially in vehicles with limited room. The main diaphragm material is paper, which provides a natural sound character. It includes a 25 mm voice coil and a ferrite magnet, together offering a nominal impedance of 4 Ohms. With an RMS power of 60 W and a sensitivity of 89 dB, this speaker is suitable for moderate volumes that ensure high sound fidelity. The frequency response ranges from 150 Hz to 5,000 Hz, optimal for clear mids.

What are the Thiele Small parameters of the Rhapsodis 3.5 and their significance?

The Thiele Small parameters of the Rhapsodis 3.5 by Quartorigo are crucial for predicting speaker performance in various enclosures. The Fs value of 122.06 Hz indicates the resonance frequency. Qms is 5.13, Qes is 1.51, and Qts is 1.16, parameters that express the quality of the speaker. Vas is 0.81 liters, describing the equivalent air volume. Other important measurements are Cms at 0.39 mm/N and Mms at 4.35 g, which represent the compliance of the diaphragm and its mass. These parameters are essential for calculating enclosure tuning.

How do I integrate the Rhapsodis 3.5 into a car sound system?

Integrating the Rhapsodis 3.5 by Quartorigo into a car sound system requires consideration of the dimensions of 3.5 inches, which is 8.9 cm. This size fits most standardized installation spaces for midrange speakers. An RMS power of 60 W and a nominal impedance of 4 Ohms make it compatible with common car amplifiers and head units. Ensure that the installation depth is sufficient and that the speaker is properly secured to minimize vibrations. Cable connections should be stable to avoid power loss.

What frequency ranges does the Rhapsodis 3.5 cover?

The Rhapsodis 3.5 from Quartorigo operates in a frequency range of 150 Hz to 5,000 Hz. This covers most of the mid frequencies that are crucial for clarity and speech intelligibility in an audio setup. The lower limit of 150 Hz means it does not reproduce deep bass, which should be complemented by a Subwoofer. The upper frequency of 5,000 Hz allows for detailed reproduction of instruments like guitars or synthesizers. This frequency response is particularly suitable for use in 2-way or 3-way systems, where higher ranges are handled by a Tweeter.

How does the ferrite magnetic material affect the Rhapsodis 3.5?

Ferrite as a magnetic material in the Rhapsodis 3.5 from Quartorigo significantly influences efficiency and weight. Ferrite magnets are known for their cost-effectiveness and durability, making them a popular choice in quality speakers. They ensure stable performance ratios and compensate for temperature changes due to their low thermal conductivity. This contributes to the longevity of the speaker. Due to their weight, ferrite magnets are slightly heavier than neodymium alternatives, which can be a factor for mobile applications; however, the sound output for the given volume is optimal.

For which applications is the paper diaphragm in the Rhapsodis 3.5 suitable?

The paper diaphragm of the Rhapsodis 3.5 from Quartorigo is optimal for applications that prefer naturalness and warmth in sound. Paper is lightweight, allowing the diaphragm to move quickly, thus providing clear tones and excellent detail richness. Especially if you enjoy listening to acoustic instruments or vocals in their purest form, this material delivers an uncolored sound experience. Additionally, paper has an advantage in damping, which reduces distortion. For high-end audio installations that require natural reproductions, paper remains unbeatable in the midrange.

What is the significance of the sensitivity of 89 dB in the Rhapsodis 3.5?

The sensitivity of 89 dB in the Rhapsodis 3.5 from Quartorigo indicates how efficiently the speaker converts electrical energy into sound. This value means that at one watt of input power and one meter away, the volume is 89 dB. This is a relatively good value that ensures you can listen to music loudly and clearly even with moderate amplifier power. Low sensitivity values reduce the need for powerful amplifiers, which is helpful when planning compact audio systems. The balance with impedance is crucial to find the right tuning in the system.

What performance characteristics does the Rhapsodis 3.5 have?

The Rhapsodis 3.5 from Quartorigo has an RMS power of 60 W, which means it can handle 60 watts continuously without distortion or damage. During peak loads, it can briefly manage higher power levels as long as they are not sustained. A precise interaction with a matched amplifier is therefore important to fully utilize its performance without overloading the components and reducing their lifespan. Ideally, the amplifier power should be within the RMS power limit to guarantee an optimal audio experience.

What impedance characteristics does the Rhapsodis 3.5 offer?

The Rhapsodis 3.5 from Quartorigo has a nominal impedance of 4 ohms. This impedance characteristic is significant for selecting an amplifier, as it must operate stably with low impedance values. Commonly used hi-fi amplifiers are designed to work optimally with 4-ohm speakers, making it a compatible and versatile option for culture enthusiasts. Adjustments in the crossover or amplifier selection can optimize the overall system's efficiency. Ensure that all components match to avoid power losses.

How are the QS parameters of the Rhapsodis 3.5 used in development?

The QS parameters of the Rhapsodis 3.5 from Quartorigo, particularly Qms (5.13), Qes (1.51), and Qts (1.16), are especially helpful for engineers designing enclosures. Qms measures the mechanical quality of the speaker, Qes the electrical quality, and Qts the overall quality. High values in these areas indicate good damping and current efficiency. In box design, they help achieve Butterworth or Chebyshev tuning. This ensures that the speaker can fully realize its potential in various configurations, whether in closed or open enclosures.
