Frequently Asked Questions about Radioactive SQ GZRC 165.3SQ-ACT

How is the Radioactive SQ GZRC 165.3SQ-ACT installed in the car?

When installing the Radioactive SQ GZRC 165.3SQ-ACT, it is important to consider the exact dimensions of 165 mm in diameter and a mounting depth of 68 mm. The mounting opening should have a diameter of 142.5 mm. Since it is an active 3-way component system, no crossover is needed, which simplifies installation. The correct placement of the tweeters (GZRT 25SQ) and midrange drivers (GZRM 80SQ) can significantly affect the sound. Pay attention to the placement of the protective grilles to protect the membranes. A suitable installation location without resonances improves the listening experience.

What technical features does the Radioactive SQ GZRC 165.3SQ-ACT offer?

The Radioactive SQ GZRC 165.3SQ-ACT is characterized by its black anodized aluminum membrane and a rubber surround that ensure clarity and precision. A resonance-optimized steel basket contributes to stability, while the Nomex spider ensures durability. The frequency response of 35 Hz to 25 kHz combined with an efficiency of 90 dB allows for a wide spectrum to be reproduced clearly and in detail. This 3-way component system has been specifically designed for active operation without crossovers, allowing for flexible integration into existing audio systems.

What are the components of the Radioactive SQ GZRC 165.3SQ-ACT speaker system?

The Radioactive SQ GZRC 165.3SQ-ACT includes various specialized components: The tweeter GZRT 25SQ provides clear reproduction of high frequencies. The midrange driver GZRM 80SQ is designed to accurately represent mid frequencies. The woofer GZRK 165SQ completes the set by powerfully reproducing low and mid frequencies. This division allows the speaker system to create a precise soundstage. Additionally, protective grilles are included to ensure the longevity of the speaker components.

What frequencies does the Radioactive SQ GZRC 165.3SQ-ACT cover?

The Radioactive SQ GZRC 165.3SQ-ACT has an impressive frequency response of 35 Hz to 25 kHz, covering both deep bass and high treble. This range, combined with an efficiency of 90 dB, provides consistent and clear audio playback even at higher volumes. The crossover frequencies at 200 Hz and 4300 Hz ensure that the transition between the individual components of the 3-way system is harmonious, without frequency cancellations or overlaps.

Why is the aluminum diaphragm of the Radioactive SQ GZRC 165.3SQ-ACT advantageous?

The black anodized aluminum diaphragm of the Radioactive SQ GZRC 165.3SQ-ACT offers several advantages: aluminum is lightweight, allowing for quick movements and thus leading to precise sound reproduction. The anodization protects the material from corrosion and increases its lifespan. This design improves detail fidelity in music reproduction, especially in high and mid tones. Especially if you enjoy listening to music loudly, the sound remains clear without distortion. The combination with the rubber surround helps minimize unwanted resonances.

How does the resonance-optimized steel basket affect the performance of the Radioactive SQ GZRC 165.3SQ-ACT?

The resonance-optimized steel basket of the Radioactive SQ GZRC 165.3SQ-ACT plays a crucial role in sound quality. By minimizing self-resonances, the steel basket supports uncolored sound reproduction, which is particularly beneficial at higher volumes. The stable frame reduces vibrations that could disturb the sound image, ensuring more precise audio playback. This is especially helpful when complex musical pieces are played, as each speaker fulfills its task without sonic impairments.

What role does the Nomex spider play in the Radioactive SQ GZRC 165.3SQ-ACT?

The Nomex spider in the Radioactive SQ GZRC 165.3SQ-ACT is a central component for the mechanical stability of the speaker. Nomex, known for its heat resistance and strength, ensures that the speaker diaphragm remains in the correct position and moves evenly even under prolonged load. This reduces distortion in audio playback and contributes to a higher overall lifespan of the speaker. In combination with the rubber surround, the spider allows for precise movement control, significantly supporting sound clarity.

Is the Radioactive SQ GZRC 165.3SQ-ACT compatible with my car?

The compatibility of the Radioactive SQ GZRC 165.3SQ-ACT depends on the space available in your vehicle. With a diameter of 165 mm and a mounting depth of 68 mm, as well as a mounting opening of 142.5 mm, this system is universally adaptable for installation, provided the specified dimensions are available in your vehicle. Additionally, the mounting points must effectively absorb vibrations to allow bass tones without distortion. However, for older or specialized car brands, it may be necessary to make adjustments so that the sound of the speaker is fully realized.

What advantages does the efficiency of 90 dB offer with the Radioactive SQ GZRC 165.3SQ-ACT?

An efficiency of 90 dB with the Radioactive SQ GZRC 165.3SQ-ACT means that the speaker is efficient and delivers high volume with low power consumption. This is beneficial when the amplifier's power reserves are limited. A higher efficiency also ensures that sound details are clearly perceivable during playback of both quieter and louder passages. Especially in actively operated systems without additional crossovers, this provides flexibility in integration to adjust the sound according to personal preferences.

What crossover frequencies does the Radioactive SQ GZRC 165.3SQ-ACT have?

The Radioactive SQ GZRC 165.3SQ-ACT has crossover frequencies at 200 Hz and 4300 Hz. These crossover frequencies are crucial for the seamless interface between the various speaker components of the system. At 200 Hz, the low/mid-range is handed over to the midrange driver, while at 4300 Hz, the tweeter takes over. A precise tuning of these frequencies helps to avoid frequency gaps or overlaps, creating a smooth and detailed sound image, thus ensuring an optimal listening experience.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
