Its double-waved damped fabric surrounds ensure high linearity, even under extreme conditions. Its mechanical and thermal capabilities are designed to excel in demanding applications. With a peak power handling of 500 W, the midrange driver can deliver outstanding performance even at high volumes. The use of high-density ferrite also ensures that sound reproduction remains stable and precise.

What are the Thiele-Small parameters of the SPL Show SV 250.1?

The Thiele-Small parameters of the Hertz SPL Show SV 250.1 include: Re 3.3 Ohm, Fs 90 Hz, Vas 20 l, Qts 0.4, Qes 0.42, Qms 12.1, and BL 10.7 T*m. These parameters help determine the behavior of the speaker in a box and are crucial for the correct enclosure design during installation. They provide information about the resonance frequency, electrical and mechanical damping, as well as the volume behavior of the speaker. By considering these parameters, the performance of the speaker in various audio applications can be maximized.

What are the size and weight of the SPL Show SV 250.1?

The Hertz SPL Show SV 250.1 has a size of 250 mm in diameter, which corresponds to a 10-inch speaker. The specific dimensions are A: 257 mm, B: 232 mm, C: 108 mm, and D: 101 mm, which play a significant role in selecting the appropriate installation boxes. The speaker weighs 4 kg, making it relatively lightweight in its category, without compromising on stability and performance. These dimensions allow for integration into various audio setups without affecting the structural integrity of a vehicle.

Which car brands is the Hertz SPL Show SV 250.1 compatible with?

The Hertz SPL Show SV 250.1 is universally installable thanks to its dimensions: A: 257 mm, B: 232 mm, C: 108 mm, and D: 101 mm, and fits into many common vehicle models. However, it is advisable to measure the available installation spaces in your vehicle before installation and compare them with the speaker dimensions. Due to its design, the speaker is particularly suitable for SPL applications where high volumes are required while maintaining high sound quality. However, installation may vary depending on the specific dimensions of the vehicle.

What are the load capacity values of the SPL Show SV 250.1?

The SPL Show SV 250.1 from Hertz offers a load capacity of 250 watts RMS, while the peak load capacity is an impressive 500 watts. These values make it an ideal candidate for powerful audio systems where high volumes are demanded without compromising quality. A 4-ohm impedance value helps ensure that the speaker works efficiently with most modern amplifiers. Especially if you enjoy listening to music loudly, this midrange driver guarantees consistent and powerful sound reproduction even at maximum volume.

What material is used for the diaphragm of the Hertz SPL Show SV 250.1?

The diaphragm of the SPL Show SV 250.1 is made of ultra-light press paper that has a water-repellent coating. This combination of material and coating not only ensures high resistance to moisture but also outstanding acoustic performance. The ultra-light structure of the diaphragm allows for fast and precise reproduction of audio signals, while the water-repellent properties increase the durability of the speaker under various operating conditions.

What are the frequency response values of the SPL Show SV 250.1?

The frequency response of the Hertz SPL Show SV 250.1 ranges from 90 Hz to 7 kHz. This bandwidth allows the speaker to cover a large part of the audio frequency spectrum, particularly from low bass to the mid-frequency range. These characteristics make it especially suitable for audio applications where dynamic bass and clear midrange reproduction are important. Whether in combination with tweeters or as a standalone midrange driver, the SPL Show SV 250.1 delivers impressive performance across the specified frequency range.

How is the installation of the SPL Show SV 250.1 in the vehicle designed?

When installing the SPL Show SV 250.1, it is important to consider the dimensions A: 257 mm, B: 232 mm, C: 108 mm, and D: 101 mm. The correct placement and securing in the vehicle ensure optimal sound quality and prevent unwanted vibrations. Decoupling from the chassis can be achieved using sealing material and suitable screws to achieve a perfect seal. When wiring, attention should be paid to correct polarity and as short cable runs as possible to avoid power deficits. These factors significantly influence overall performance and sound characteristics.

What is the size of the magnet in the Hertz SPL Show SV 250.1 and what does that mean for sound quality?

The Hertz SPL Show SV 250.1 is equipped with a magnet measuring 155 x 70 x 20 mm made of high-density flux ferrite. This magnet structure significantly contributes to the efficiency and precision of sound conversion. A larger magnet means a stronger magnetic driving force in this case, leading to better control of diaphragm movements. For the listener, this results in clearer, more dynamic playback even at high volumes. The precise construction of this driver optimizes sound transparency and enhances overall sound perception when used in SPL systems.

What sound pressure level (SPL) does the Hertz SPL Show SV 250.1 achieve?

The Hertz SPL Show SV 250.1 achieves a maximum sound pressure level of 101 dB. Such a high SPL value is designed for SPL systems where it is important to produce loud and clear playback.
