Frequently Asked Questions about STW-350F-188PR01-04

What is the RMS power of the STW-350F-188PR01-04 Subwoofer?

The STW-350F-188PR01-04 Subwoofer from Peerless by Tymphany offers an impressive RMS power of 3,500 watts. This figure refers to the continuous power that the subwoofer can handle without damage or loss of performance. With this enormous power, the subwoofer is capable of producing deep and powerful bass, which is particularly beneficial for music lovers who enjoy listening at high volumes. The dual 8-ohm voice coil allows for flexible impedance matching in different setup configurations. The maximum power handling even reaches 5,000 watts.

What are the dimensions of the STW-350F-188PR01-04 Subwoofer?

The STW-350F-188PR01-04 Subwoofer has an overall outer diameter of 38 cm and an impressive depth of 23.3 cm. The cutout diameter, which is the required diameter of the installation space in the enclosure, is 34.8 cm. With these dimensions, the subwoofer fits well into various enclosure types, increasing flexibility during installation. Also important are the eight mounting holes that ensure secure attachment. Compatibility with car models would depend on appropriate adjustments to the installation locations to meet the subwoofer's space requirements and ensure optimal performance.

What frequency range is covered by the STW-350F-188PR01-04 Subwoofer?

The STW-350F-188PR01-04 Subwoofer covers a frequency range from 10 to 500 Hz. This gives it the ability to reproduce very deep bass that is lower than many other available models on the market. The lower cutoff frequency of 10 Hz ensures powerful, earthquake-like deep bass reproduction, while the upper cutoff frequency of 500 Hz provides clear mid-bass. This model is ideal for users seeking comprehensive low-frequency reproduction in their audio system. Combined with a sensitivity of 88.7 dB, the sound remains detailed even at low input signals.

What is the mechanical excursion of the STW-350F-188PR01-04 Subwoofer?

The mechanical displacement of the STW-350F-188PR01-04 Subwoofer exceeds 90 mm peak-to-peak. This allows for enormous movement of the diaphragm and is crucial for the subwoofer's ability to generate high sound pressure levels. The maximum linear displacement, Xmax, is ±10.4 mm, which means that the diaphragm can move linearly without distortion over this range. Additionally, the subwoofer is equipped with a voice coil length of 57 mm, allowing for displacements of up to 45.5 mm before exceeding a larger BL loss. This contributes to the overall high performance.

What enclosure recommendations are there for the STW-350F-188PR01-04 Subwoofer?

There are several enclosure recommendations for the STW-350F-188PR01-04 Subwoofer depending on the desired sound profile. For a sealed enclosure, a volume of 56 liters is recommended, resulting in a lower cutoff frequency of 42 Hz at -3 dB. Two vented enclosure configurations are also recommended: one with 82 liters, a port of 200 cm², and 70 cm length for a lower cutoff frequency of 24.2 Hz, and a larger one with 130 liters, a port of 180 cm², and 90 cm length for a cutoff frequency of 20 Hz. These variants offer flexible adjustment options regarding bass reproduction.

What are the Thiele Small parameters of the STW-350F-188PR01-04 Subwoofer?

The Thiele Small parameters of the STW-350F-188PR01-04 Subwoofer include a resonance frequency (Fs) of 25.3 Hz, mechanical quality factor (Qms) of 11.39, electrical quality factor (Qes) of 0.5, and a total quality factor (Qts) of 0.48. The moving mass (Mms) is 576.8 g, and the mechanical compliance (Cms) is 0.068 mm/N. The diaphragm area (Sd) is specified as 774.4 cm², and the equivalent volume (Vas) is 58 liters. These parameters are crucial for understanding the acoustic properties and for proper enclosure tuning, as they have significant influences on acoustic performance.

How does the ferrite magnet structure affect the performance of the STW-350F-188PR01-04?

The internal ferrite magnet structure of the STW-350F-188PR01-04 Subwoofer plays a significant role in the performance of this device. The use of ferrite as a magnet material provides a stable and strong magnetic field, which efficiently drives the voice coil. The FEA optimization of the magnet structure further improves magnetic efficiency and ensures an even coil force distribution over the full stroke range. Together with the large aluminum short-circuit rings, a reduction in magnetic distortion is achieved, which is reflected in a clearer sound image. This construction allows for high dynamics and punch in bass reproduction.

What impedance values does the STW-350F-188PR01-04 Subwoofer offer?

The STW-350F-188PR01-04 Subwoofer is equipped with a dual 8 Ohm voice coil, referred to as impedance D8. This configuration allows for flexible adjustment of the total impedance to different amplifier systems through parallel connections, series connections, or separate control of the individual coils. The DC resistance (Re) of the subwoofer is 3.2 Ohm, which is another variable in adapting to the amplifier system. Impedance plays a significant role in electrical coupling and significantly influences the overall performance and behavior of the subwoofer in various audio systems.

What materials are used in the STW-350F-188PR01-04 Subwoofer?

The STW-350F-188PR01-04 Subwoofer from Peerless by Tymphany uses a carefully selected combination of materials to ensure optimal acoustic performance. The diaphragm is made from a blend of paper and carbon fiber, providing a perfect balance between stiffness and damping. The surround is made of rubber, ensuring long-lasting flexibility and damping of movement. The voice coil wire is made of copper and is wound onto a fiberglass former, which increases thermal resilience. The entire assembly is housed in a robust aluminum die-cast basket, which, in combination with the ferrite magnet, provides stability and minimizes vibrations.

What is the sensitivity of the STW-350F-188PR01-04 Subwoofer?

The STW-350F-188PR01-04 offers a sensitivity of 88.7 dB at 2.83 V/1 m. This figure indicates how efficiently the subwoofer converts the applied electrical power into sound. Higher sensitivity means that the subwoofer can produce a higher volume with less power from the amplifier. This is particularly advantageous when efficient energy conversion and high acoustic performance are desired in an audio project. This specific sensitivity is ideal for ensuring peak performance with minimal power loss when combined with powerful amplifier units.
