Frequently Asked Questions about QXP124

What is the maximum load capacity of the QXP124 Subwoofer?

The QXP124 from ESX can achieve an impressive peak power of 1000 watts. It primarily operates with a nominal load capacity of 500 watts (music), making it ideal for bass lovers who appreciate powerful, punchy sounds. These power values are supported by the robust construction of the Subwoofer, which includes a 39 mm dual voice coil and a massive Y35 dual magnet weighing 3.1 kg. All these features together enable an intense sound experience with a full frequency range.

What is the installation depth of the ESX QXP124 and what advantages does it offer?

The QXP124 offers a remarkable installation depth of only 89 mm. This shallow depth is ideal for vehicles with limited space and allows for a space-saving installation without sacrificing performance. However, due to this flat design, certain design considerations may be necessary to optimize air circulation within the enclosure and thus maximize sound quality. Especially in tight spaces, the innovative construction fully showcases its strengths.

What technical parameters define the acoustic performance of the QXP124?

The QXP124 has remarkable acoustic parameters: The Thiele-Small parameters such as Fs at 26 Hz, a Qts of 0.55, and a VAS of 52.2 liters. With a sensitivity of 88 dB/2.83V/1m, the Subwoofer delivers excellent performance even at lower input power levels. These parameters are crucial for optimally matching the Subwoofer to the enclosure volume used and further optimizing the frequency response, which ultimately significantly improves sound quality.

How do polypropylene diaphragm and aluminum die-cast basket differ in sound quality?

The polypropylene diaphragm of the ESX QXP124 ensures a quick response and is resistant to moisture and temperature fluctuations. Combined with the aluminum die-cast basket, it creates a rigid yet lightweight structure that minimizes distortion and allows for even sound distribution. The die-cast basket provides stability to the Subwoofer and reduces unwanted resonances. These elements work together to maximize bass resonance and deliver an immersive listening experience.

What type of enclosure is recommended for the QXP124?

The ESX QXP124 is optimally designed for closed enclosures with a volume of around 22 liters or more. This recommendation is based on the tuning of the Thiele-Small parameters, which promote precise bass reproduction in this type of enclosure. The closed design improves control over the diaphragm behavior, resulting in tighter and more accurate bass reproduction. This characteristic supports precise playback of music pieces with fast bass runs and rhythmic elements.

What features does the dual voice coil of the QXP124 have?

The dual voice coil of the QXP124 is 39 mm in size and has a winding height of 36 mm. This design allows for more electrical power to be converted into mechanical movement, increasing the dynamic range and linear displacement. The dual nature of the voice coil also improves heat dissipation and allows for more flexible impedance matching. All these features contribute to maximizing output power and minimizing distortion at high volumes.

How can the ESX QXP124 be integrated into a vehicle?

With a mounting hole of 286 mm and a mounting depth of 89 mm, the QXP124 is suitable for subtle adjustments in various vehicle types. The installation requires precise fitting in the vehicle body to ensure a perfect air seal. The integration of the aluminum die-cast basket requires special screw connections to minimize vibrations. The metal grille, included in the package, provides additional protection against physical impacts in the vehicle.

What role does the Y35 dual magnet play in the QXP124?

In the QXP124, the Y35 dual magnet, with a total weight of 3.1 kg, provides an increased magnetic flux density. This leads to enhanced efficiency in the movement of the diaphragm and results in powerful and clear bass. The dual magnet structure allows for a stronger and more uniform magnetic field distribution, reducing distortion and improving overall sound fidelity. This technology significantly contributes to the performance of the Subwoofer and enables consistent performance even at higher volumes.

What is the X-Max of the QXP124 and how does it affect the sound?

The X-Max of the QXP124 is +/- 20 mm, which is a measure of the maximum mechanical displacement of the diaphragm while maintaining linear playback. This large displacement capability allows for deep bass frequencies to be reproduced without distortion, which is especially important at high volume and high sound pressure levels. The ability to displace so far while preserving sound integrity is a key advantage of this Subwoofer and essential for powerful yet precise bass reproduction.

What impedance is the QXP124 designed for and what does that mean for the connection?

The QXP124 from ESX is designed for an impedance of 4 ohms, which is the most common choice in car and amplifier systems. This impedance allows for integration into most standard amplifier systems and ensures efficient power distribution without the need for adjustments or bypasses. The 4-ohm configuration ensures that power loss is minimized and the Subwoofer can operate efficiently, even with off-the-shelf amplifiers. This results in a full, clear sound that is especially desired in car bass systems.

Top für den Preis !!!

Hören sich gut an!!! hätte ich nicht gedacht in der Preisklasse, vor allem der Pegel hab sie mit paar Axton Hochtönern verbaut und einem Kicker sub im Kofferraum und paar Rainbow Endstufen sauberer lauter klang bin sehr zufrieden mit dem Produkt. Langzeit noch keine Erfahrung da erst zwei Wochen verbaut

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
