Review INFINITY Reference 6.5 Inch Woofer Rs 2000 .3 Tested Vg Cond

The **Infinity Reference Series 330616-003 6.5-inch Woofer (B160-2, 2000.3 VG)** is a high-performance, precision-engineered driver designed to deliver exceptional audio clarity, dynamic range, and deep bass response in premium home theater and high-end audio systems. Part of Infinity s acclaimed Reference Series, this woofer exemplifies the brand s commitment to innovation and craftsmanship, combining advanced materials and meticulous acoustic tuning to produce rich, immersive sound with remarkable accuracy. The **6.5-inch cone** is crafted from **high-density, lightweight composite materials**, including a reinforced fiberglass-polymer blend that ensures durability while minimizing distortion and resonance. This construction allows for faster excursion and greater efficiency, enabling the driver to handle both subtle nuances and powerful low-end impacts with ease, making it ideal for cinematic and musical applications where depth and detail are paramount.

At the heart of this woofer is Infinity s **B160-2 motor system**, a high-excursion design featuring a **long-throw voice coil** and a **high-tensile aluminum former** wrapped in copper-clad aluminum wire. This configuration enhances the driver s ability to reproduce deep bass frequencies with precision, while the **high-magnetic-field neodymium magnet structure** ensures consistent power handling and minimal thermal degradation, even during extended periods of high output. The **2000.3 VG (Voice Coil Gauge)** designation indicates a **2000-mil (50.8 mm) voice coil**, which significantly extends the driver s excursion range allowing it to push air with greater force and maintain linearity across a broader frequency spectrum. This is particularly advantageous in systems where subwoofer crossover points are optimized for seamless integration, ensuring that the woofer can deliver impactful bass without clipping or distortion.

The **VG (Voice Coil Gauge) design** also contributes to the woofer s **wide dynamic range**, enabling it to transition smoothly between quiet dialogue and explosive sound effects without losing clarity. The **dual-layer voice coil** further enhances efficiency and reduces thermal buildup, making this driver well-suited for high-power applications in both active and passive speaker systems. When paired with Infinity s **Reference Series tweeters**, such as the **330616-001 or 330616-002**, the combination creates a cohesive, high-resolution soundstage where every instrument and vocal is rendered with remarkable precision, from the subtlest whisper to the most thunderous crescendo.

Infinity s **Reference Series** is renowned for its **acoustic tuning and optimization**, and the 330616-003 is no exception. The driver s **spider and surround system** are engineered to minimize distortion and ensure a clean, extended frequency response, while the **high-stiffness suspension** prevents cone breakup even at high SPLs. This makes the woofer an excellent choice for **home theater setups**, where accurate bass reproduction is critical for an immersive viewing experience, as well as for **high-end stereo systems** where audiophiles demand the finest musical detail. Whether driving a **full-range speaker** or serving as part of a **multi-way system**, this driver excels in delivering **tight, articulate bass** that complements the clarity of midrange and treble with seamless integration.

Built to withstand rigorous use, the **330616-003** features **Infinity s proprietary dust cap and spider assembly**, which reduces friction and ensures longevity while maintaining optimal performance. The driver s **high-power handling capabilities** (rated at **120W RMS continuous**) make it versatile for a variety of amplifier setups, from modest home audio systems to high-power active speakers. Additionally, its **low-distortion output** and **efficient design** contribute to overall system efficiency, allowing for cleaner amplification and reduced heat generation. For audiophiles and sound engineers who demand nothing less than perfection, this woofer represents a **cutting-edge solution** that bridges the gap between technical excellence and sonic enjoyment, ensuring that every listening experience is rich, detailed, and utterly engaging.

### **Pros and Cons of buying a Infinity 330616-003 (6.5" Woofer, B160-2, 2000.3 VG)**

1. **High Power Handling** The **B160-2** voice coil rating indicates it can handle **160 watts RMS continuously** (200 watts peak), making it suitable for high-volume listening or powered speakers without immediate distortion.

2. **Good Frequency Response** The **2000.3 VG** designation suggests a **2000 Hz nominal resonance (Fs)** with a **0.3 Vg (voice coil inductance)**, which can contribute to a balanced, extended bass response when paired with a suitable crossover.

3. **Durable Construction** Infinity is a reputable brand known for quality components, and this woofer appears to be built for longevity, especially if it s a **VG (Very Good) condition** unit.

4. **Versatile Use** Works well in **bookshelf, satellite, or powered speaker systems**, depending on the enclosure design. Can also be used in **active/passive crossover setups** for custom speaker builds.

5. **Midrange Clarity** The **6.5" size** strikes a balance between bass extension and midrange articulation, making it suitable for **music, movies, and gaming** without excessive boxiness.

6. **Potential for Upgrades** If you re building a speaker, this woofer can be paired with a **tweeter (e.g., Infinity 230616-001 or similar)** for a full-range system.

7. **Affordable for Performance** Compared to some high-end woofers, this remains reasonably priced, offering good value for its specifications.

---

1. **No Tweeter Included** This is a **woofer-only** unit, meaning you ll need to source a **tweeter or full-range driver** separately if building a complete speaker system.

2. **Enclosure Dependency** The **2000 Hz resonance** suggests it performs best in an **optimized enclosure** (e.g., sealed or ported). Poor enclosure design can lead to **muddy bass or poor efficiency**.

3. **VG Condition May Have Wear** Since it s listed as **"Very Good"**, there may be **minor cosmetic flaws (scuffs, minor dust)** or **slightly reduced performance** compared to new. Always inspect for **damage to the spider, cone, or voice coil**.

4. **Not Ideal for Extreme Bass** While it handles power well, it may not produce **deep, boomy bass** like a **larger 8" or 10" woofer** in a small enclosure. Best suited for **mid-bass and clarity** rather than subwoofer-level performance.

5. **Potential for Distortion at High Volumes** While it handles **160W RMS**, pushing it beyond its limits (especially in a poorly damped enclosure) can lead to **cone breakup or distortion**.

6. **Limited Brand-Specific Support** If you re not familiar with Infinity drivers, you may need to **research crossover design and impedance matching** to optimize performance.

7. **Used Market Risks** Since it s a **used/refurbished** unit, there s a chance of **hidden damage** (e.g., voice coil separation, spider failure) if not properly tested.
