---

### **Pros of the Dayton Audio PC68-8-S**

1. **Versatility in Design**

The PC68-8-S is a full-range driver, meaning it can handle both midrange and bass frequencies without requiring a separate woofer or tweeter. This makes it ideal for compact systems, such as bookshelf speakers, subwoofers, or even as a single-driver design in a sealed or ported enclosure. Its 2.5-inch diameter also allows for efficient use of space in smaller cabinets.

2. **High Sensitivity (92 dB/W/m)**

With a sensitivity of 92 dB/W/m, this driver is relatively efficient, meaning it produces more sound output for a given amount of power input. This can result in a more powerful and dynamic sound without requiring excessive amplification, which is beneficial for home audio or small venues.

3. **Wide Frequency Response**

The PC68-8-S has a frequency response range of 75 Hz to 20 kHz, which covers the full audio spectrum. This makes it suitable for applications where a broad frequency range is desired, such as in high-fidelity speaker systems or subwoofers that need to extend down to lower frequencies.

4. **Polypropylene Cone Material**

The polycone material is lightweight yet stiff, which helps reduce distortion and improves transient response. Polypropylene is also resistant to moisture and temperature fluctuations, making the driver more durable in varying environmental conditions.

5. **Low Distortion**

Dayton Audio drivers are known for their low distortion characteristics, and the PC68-8-S is no exception. This results in cleaner and more accurate sound reproduction, which is critical for audiophiles or professional applications.

6. **Compatibility with Amplifiers**

The driver s impedance is 8 ohms, which is a standard value and compatible with most amplifiers. This makes it easy to pair with a wide range of power amplifiers without needing to worry about impedance mismatches.

7. **Durability and Build Quality**

Dayton Audio drivers are generally well-built, with robust voice coils and sturdy surrounds. The PC68-8-S is no different, offering reliable performance over time with proper care and usage.

8. **Cost-Effective for Performance**

Compared to some high-end drivers, the PC68-8-S offers excellent performance at a relatively affordable price. This makes it an attractive option for DIY speaker builders or those looking to upgrade their audio systems without breaking the bank.

### **Cons of the Dayton Audio PC68-8-S**

1. **Limited Bass Extension in Small Enclosures**

While the PC68-8-S can handle bass frequencies down to 75 Hz, its small size (2.5 inches) means that it may struggle to produce deep, powerful bass in sealed enclosures without significant amplification. For true subwoofer applications, a larger driver (e.g., 5 inches or more) is often preferred. In a sealed enclosure, the bass response may be limited unless the enclosure is optimized for the driver s capabilities.

2. **Not Ideal for High-Power Applications**

The PC68-8-S is not designed for extremely high-power applications. While it can handle moderate power levels (typically up to 50-100 watts continuous, depending on the system), pushing it beyond its limits can lead to distortion or even damage to the driver. For high-power systems, larger drivers with thicker voice coils are often recommended.

3. **Requires Proper Enclosure Design**

Like all drivers, the PC68-8-S performs best when used in an enclosure that is properly tuned to its specifications. A poorly designed enclosure (e.g., one that is too small or lacks proper damping) can result in poor bass response, increased distortion, or even damage to the driver. DIY builders must have a good understanding of enclosure design principles to maximize performance.

4. **Limited Tweeter Options for Full-Range Use**

If you intend to use the PC68-8-S as a full-range driver in a two-way or three-way system, you will need to pair it with a tweeter. Dayton Audio offers compatible tweeters (e.g., the DT series), but you will need to ensure proper crossover design and matching impedance to avoid issues like clipping or distortion.

5. **Not Suitable for Outdoor or Harsh Environments**

While the polycone material is durable, the PC68-8-S is not designed for outdoor use or extreme conditions (e.g., high humidity, dust, or temperature fluctuations). It is best suited for indoor applications where environmental conditions are controlled.

6. **Learning Curve for DIY Builders**

For those new to speaker building, the PC68-8-S may require some learning to achieve optimal performance. Proper crossover design, enclosure tuning, and wiring are all critical factors that can affect sound quality. Beginners may need to refer to detailed guides or seek advice from experienced builders.

7. **Sound Signature May Not Suit All Preferences**

The PC68-8-S has a neutral to slightly extended high-frequency response, which some listeners may find bright or harsh. While this can be mitigated with proper crossover design and cabinet materials, individual preferences for sound signature (e.g., warm, neutral, or extended) may vary.

---

### **Conclusion**

The Dayton Audio PC68-8-S is a well-rounded, versatile driver that excels in compact speaker systems, subwoofers, or as a full-range driver in sealed or ported enclosures. Its high sensitivity, wide frequency response, and low distortion make it a strong choice for DIY builders and audiophiles looking for a balance of performance and affordability. However, its small size limits its bass extension in sealed enclosures, and it requires proper enclosure design and crossover work to achieve its best performance.

For those with a basic understanding of speaker design, the PC68-8-S is an excellent option for building compact, efficient speakers or subwoofers. Beginners may find it a bit challenging due to its requirements for proper tuning, but the results can be rewarding. If you prioritize deep bass or high-power handling, you may need to consider larger drivers, but for most midrange and full-range applications, the PC68-8-S is a solid and cost-effective choice.

### **Recommendation**

- You are building a compact speaker system (e.g., bookshelf, desktop, or small floor-standing speakers).

- You want a full-range driver that can handle midrange and light bass without requiring a separate woofer.

- You have access to or are willing to learn about enclosure design and crossover work.

- You prefer a neutral to slightly extended sound signature and are satisfied with its frequency response.

- You are on a budget but still want high-quality performance.

- You need deep bass extension (below 60 Hz) in a sealed enclosure, as a larger driver (e.g., 5 inches or more) would be more appropriate.

- You are building a high-power system (e.g., for car audio or large venues) and require a driver with thicker voice coils.

- You lack experience with speaker design and are unsure about proper enclosure tuning or crossover design.

- You prefer a warmer or more extended bass response and are not willing to experiment with cabinet materials or enclosure tuning.

- For deeper bass, consider the Dayton Audio PC18-8-S (5 inches) or other 4-inch to 6-inch drivers.

- For a tweeter pairing, the Dayton Audio DT series (e.g., DT1260) is a good match.

- If you are new to speaker building, start with a pre-made speaker system or a simpler driver (e.g., a 5-inch woofer with a built-in crossover) to gain experience before using the PC68-8-S.

Overall, the PC68-8-S is a fantastic driver for those who understand its limitations and are willing to work with it to achieve great results. For most DIY enthusiasts, it offers an excellent balance of performance and value.
