What materials are used in the HMX 8.8 S-LD-G.2?

The Hertz HMX 8.8 S-LD-G.2 uses high-quality materials to deliver optimal sound results. The mid-woofers utilize magnet material made from high-density ferrite, while the tweeter is equipped with neodymium magnets. The diaphragm material consists of polypropylene with UV inhibitors, a robust and weather-resistant material that ensures durability. The tweeter is made from polyetherimide (PEI), which contributes to improved sound reproduction. This choice of materials guarantees not only durability but also top-notch acoustic properties.

What electro-acoustic parameters does the Hertz HMX 8.8 S-LD-G.2 have?

Regarding electro-acoustic parameters, the Hertz HMX 8.8 S-LD-G.2 has some impressive values. The effective diaphragm diameter is 174 mm, while the DC resistance is 3.1 Ohm. The resonance frequency, a crucial factor for bass reproduction, is 50 Hz. The voice coil inductance is 0.52 mH, and the equivalent volume (Vas) is 29.46 l. A moving mass of 27.3 g and a suspension compliance of 0.37 mm/N optimize sound reproduction. The force factor (BL) is 6.6 Tm, supported by the total quality factor (Qts) of 0.58.

What frequency ranges does the HMX 8.8 S-LD-G.2 cover?

These technical specifications ensure that the Tweeter is seamlessly integrated into the overall system, helping to create a balanced sound image across all frequency ranges.

How does the maximum mechanical stroke affect the sound quality of the HMX 8.8 S-LD-G.2?

The maximum mechanical stroke, also known as Xmech, describes the maximum movement that a speaker's diaphragm can make back and forth before reaching a mechanical stop. In the Hertz HMX 8.8 S-LD-G.2, this is +/- 8.5 mm. This feature is crucial as it determines how well the speaker can handle dynamic peaks and low frequencies without distortion. A larger mechanical stroke allows the speaker to reproduce deeper bass at high volumes without audible distortion, ensuring a clean sound image.

What is the rated sound pressure level of the HMX 8.8 S-LD-G.2?

The rated sound pressure level, also known as sensitivity, is a parameter that indicates how efficiently a speaker produces sound in relation to the power supplied. The Hertz HMX 8.8 S-LD-G.2 has a rated sound pressure level of 91 dB. This value indicates how loud the speaker plays with a given power. A higher dB value means that the speaker achieves more sound level from lower amplifier power. This makes it ideal for applications where high volumes are required without loss of power, especially in larger vehicles or open environments.
