Meaning of the nominal impedance value: 4 ohms

The 12W1V3-4 has a nominal impedance of 4 ohms. This value is ideal for typical one-to-one matching with most car audio amplifiers. A higher impedance could reduce volume but would increase the amplifier's lifespan. A lower impedance, on the other hand, could overload the amplifier. The 4 ohms of the JL Audio subwoofer are a balanced compromise between volume and amplifier relief.

Thiele Small Parameter Explained: Free Air Resonance Frequency at 26.21 Hz

The free-air resonance frequency (Fs) of the JL Audio 12W1V3-4 is 26.21 Hz. This low frequency predestines it for deep bass. A lower Fs gives the subwoofer the ability to reproduce even the lowest notes powerfully and unadulterated. Compared to models with a higher Fs, the 12W1V3-4 delivers more impressive bass reproduction, ideal for music genres that favor low frequencies.

Optimal mechanical quality: Qms of 8.2

With a Qms value of 8.2, the 12W1V3-4 subwoofer stands out. A higher Qms value means a more robust mechanical construction, which is essential for dynamic musical passages.

Total quality factor Qts of 0.502 for tonal flexibility

The overall Qts of the JL Audio 12W1V3-4 is 0.502, a value that determines the balance between electrical and mechanical damping characteristics. This Qts value is optimal for sealed enclosure designs and enables more precise bass reproduction. Other subwoofers that deviate from this ideal may exhibit sound characteristics that are either too soft or too harsh.

Equivalence volume Vas of 76.63 liters interpreted

The Thiele-Small parameter Vas is specified as 76.63 liters in the 12W1V3-4. This value indicates the air volume, which is proportional to the speaker's spring action, allowing you to determine the optimal cabinet size. Higher Vas values ​​indicate a larger, more efficient bass. A value that is too small, in comparison, would limit the frequency response in the low bass range.

Impressive linear displacement Xmax of 11 mm

The 11 mm Xmax of the JL Audio 12W1V3-4 enables impressive excursion, which is especially evident at high volumes. This linear excursion translates to ultra-clear bass development without distortion, even under aggressive driving. Competing car hi-fi products often offer less excursion, which can lead to a loss of sound fidelity under extreme use.

Compact housing optimization for sealed design

With a volume of just 31.5 liters, the JL Audio 12W1V3-4 is perfectly suited for compact, sealed enclosures. This saves space in the car while still delivering maximum power from the subwoofer. Unlike larger designs, this allows for very precise control of the bass sound, ideal for tight and focused soundscapes.

Adjustable cabinet parameters for bass reflex speakers

The bass reflex enclosure specifications give the 12W1V3-4 greater flexibility in use. With a net volume of 45.3 liters, the sound characteristics shift to an even deeper soundstage. A carefully tuned bass reflex design increases the volume at specific frequencies. Innovative bass port designs with a tuning frequency of 31.79 Hz make this subwoofer highly efficient.

Excellent tuning at low frequencies: F3 of 39.63 Hz

The F3 value of 39.63 Hz for sealed enclosures indicates the point at which the bass intensity of the 12W1V3-4 begins to decline, which is still more than sufficient for reproducing very low frequencies. Other subwoofers may drop off at higher frequencies, making the JL Audio 12-inch speaker an ideal choice for music styles with a deep sonic epitome.

Total weight and dimensions influence installation options

The JL Audio 12W1V3-4 has a net weight of 5.5 kg and specific dimensions (overall diameter: 318 mm, mounting depth: 137 mm). These factors facilitate installation in a wide variety of vehicle types. More compact versions like this are ideal for universal use without complex modifications.
