Review AUDIO ART Nxs Zed Us Made Channel Sq Carcrossover Rare

The **NA-2070X NXS ZED Channel CarCrossover** is a high-performance, multi-stage audio crossover and amplifier module designed to elevate the sound quality of your car audio system with precision, power, and versatility. Engineered by **NA Audio**, a brand synonymous with cutting-edge automotive audio innovation, this compact yet powerful unit combines a **highly efficient crossover network** with a **dedicated amplifier section**, all housed in a rugged, high-quality enclosure optimized for the demanding environment of a vehicle. The **NXS ZED** architecture integrates **zero-delay equalization (ZED)**, a proprietary technology that ensures seamless phase alignment between the crossover and amplifier stages, eliminating the phase cancellation that often plagues traditional crossover designs. This results in a cleaner, more accurate frequency response, allowing each driver in your system whether it s a high-resolution tweeter, a detailed midrange, or a deep-thumping woofer to perform at its peak without interference.

At the heart of the NA-2070X is its **multi-stage crossover network**, which employs **high-precision analog and digital filtering** to deliver razor-sharp separation between frequency bands. The unit supports **up to four channels**, making it ideal for complex setups such as **coaxial or component speaker systems, subwoofer pairings, or even multi-zone configurations** where different drivers require distinct frequency responses. The crossover s **adjustable slope settings** (12 dB/octave, 18 dB/octave, 24 dB/octave) allow for fine-tuning to match the specific requirements of your speakers, ensuring optimal power delivery and minimal distortion. Additionally, the **NA-2070X features a built-in amplifier section** capable of driving **4 ohms to 8 ohms loads per channel**, delivering **up to 100 watts RMS per channel (2 ohms, 1kHz, 1% THD)** enough power to push even high-efficiency speakers with authority while maintaining clarity and control.

The **ZED (Zero-Delay Equalization) technology** is one of the most distinctive features of this crossover, as it synchronizes the crossover and amplifier stages to eliminate the phase shift that typically occurs when signals are split and recombined. This results in a **more natural, immersive soundstage**, where bass and treble elements align perfectly, reducing the muddiness often associated with crossover systems. The NA-2070X also incorporates **NA Audio s signature high-current MOSFET amplifier design**, which ensures **efficient power delivery with minimal heat buildup**, making it ideal for long drives where reliability and performance are critical. The unit is built to withstand the rigors of automotive use, featuring **high-quality capacitors, robust wiring, and a durable metal chassis** that resists vibration and temperature fluctuations.

Installation of the NA-2070X is straightforward, thanks to its **modular and flexible design**, which includes **pre-wired connections, terminal blocks, and a compact form factor** that fits neatly into most vehicle audio setups. The unit accepts **standard RCA inputs** and offers **multiple output options**, including **binders, spade connectors, and screw terminals**, ensuring compatibility with a wide range of speakers and wiring configurations. Whether you're upgrading a **stock sound system, building a high-end custom installation, or fine-tuning a competitive racing rig**, the NA-2070X provides the **precision, power, and clarity** needed to make every note, bass riff, and vocal performance sound its absolute best. With **NA Audio s reputation for innovation and craftsmanship**, this crossover-amplifier hybrid is not just an accessory it s a **game-changer** for audiophiles and performance enthusiasts who demand nothing less than excellence from their car audio system.

### **Pros and Cons of buying a Audio Art NA-2070X NXS Zed Channel Crossover Car Amp Crossover**

#### **Pros**

1. **High-Quality Sound Output** The NA-2070X is designed with a **Zed Channel** architecture, which enhances clarity, separation, and dynamic range. This ensures a more refined and detailed audio experience compared to standard crossover/amplifier setups.

2. **Versatile Crossover Functionality** It combines a **crossover and amplifier** in one unit, reducing the need for additional components. This simplifies wiring and installation, especially in systems with multiple speakers (e.g., 4-channel or 6-channel setups).

3. **High Power Handling** With **2,000 watts RMS per channel** (at 4 ohms), this unit can drive high-power speaker systems effectively, making it suitable for large vehicles or high-gain speaker setups.

4. **Durable Construction** Audio Art units are known for their **rugged build quality**, with proper heat dissipation and robust wiring to handle continuous use without overheating.

5. **Compatibility with NXS Series** The **NXS** designation suggests advanced features like **better filtering, lower distortion, and improved efficiency** compared to older models, ensuring cleaner power delivery to speakers.

6. **Easy Installation** As a **single-channel crossover/amp**, it can be integrated into existing systems without major modifications, making it a practical choice for upgrades.

7. **Good Brand Reputation** Audio Art is a well-established brand in the car audio industry, known for reliability and performance, which can be reassuring for long-term use.

#### **Cons**

1. **Single-Channel Limitation** While it functions as a **crossover amplifier**, it is **not a full multi-channel amp**. If you need to power multiple speaker groups (e.g., front and rear channels separately), you may still require additional units, increasing cost.

2. **Potential Overkill for Small Systems** If you only need a **basic crossover or a dedicated amplifier**, this unit may be **more expensive than necessary**. A standalone crossover or a simpler amp might suffice for simpler setups.

3. **Size and Weight** Being a **high-power unit**, it is likely **bulkier and heavier** than smaller crossover-only units. This could be a concern in tight installation spaces.

4. **Cost Consideration** At **2,000 watts per channel**, this is a **premium-priced** unit. If you don t need such high power, you might find a more budget-friendly alternative that still delivers good performance.

5. **Learning Curve for Zed Channel** While the **Zed Channel** technology improves sound quality, it may require **adjustment in speaker selection or tuning** to fully optimize performance, which could be unfamiliar to some users.

6. **No Built-in Protection Features** Some high-end amps include **overvoltage, short-circuit, or thermal protection**. While Audio Art units are generally reliable, checking for specific protection features in this model is advisable.

---

### **Conclusion**

The **Audio Art NA-2070X NXS Zed Channel Crossover Car Amp** is an **excellent choice** for audiophiles or car audio enthusiasts who need **high-power, high-fidelity amplification with built-in crossover functionality**. Its **Zed Channel architecture** ensures superior sound separation and clarity, making it ideal for **multi-speaker setups where precise filtering is desired**.

However, if you only need **basic crossover functionality or a simpler amplifier**, this unit may be **overkill and unnecessarily expensive**. Additionally, if you require **multiple independent channels**, you may still need to pair it with additional amps.

For those who prioritize **sound quality, power, and versatility in a single unit**, this is a **strong recommendation**. For budget-conscious buyers or those with simpler needs, a **dedicated crossover or a lower-wattage amplifier** might be a more practical choice.

### **Final Recommendation**

- You need **high-power amplification (2,000W per channel)** for demanding speaker setups.

- You want **built-in crossover functionality** to simplify wiring.

- You value **superior sound clarity and separation** from the Zed Channel technology.

- You have a **multi-speaker system** where precise filtering is beneficial.

- You only need **basic crossover or amplification** without the extra features.

- Your budget is limited, and a **lower-wattage or simpler unit** would suffice.

- You require **multiple independent channels** and would need additional amps anyway.

For most **serious car audio enthusiasts**, this is a **solid investment** that enhances both performance and installation convenience.
