Review WHARFEDALE Pro Replacement Inch Driver Woofer

The Wharfedale D-643 Pro and D-643A are high-performance 12-inch woofer models designed for professional audio applications, delivering powerful and accurate bass response. These woofers are an upgrade from the standard D-643 model, featuring several advanced design elements to enhance their sonic capabilities.

The D-643 Pro and D-643A are both constructed with a glass fiber reinforced polypropylene cone, which offers excellent rigidity and durability while providing a well-balanced and natural sound. The cone's shape is engineered to minimize distortion and ensure precise movement, leading to clear and articulate bass reproduction.

The woofers come equipped with a high-temperature aluminum voice coil, which can handle high power levels and maintain stability under demanding conditions. This, combined with the oversized 2.5-inch voice coil former, allows for efficient heat dissipation and improved power handling.

The D-643 Pro and D-643A also feature a unique cast aluminum chassis, which not only adds rigidity to the overall design but also aids in heat dissipation. Additionally, the woofers come with a heavy-duty rubber surround that is both flexible and resilient, ensuring reliable performance even during extended use.

Furthermore, the woofers employ a high-frequency neodymium magnet system, which reduces weight and allows for greater efficiency and ease of movement. This results in quicker response times and improved transient accuracy, resulting in a more dynamic and lifelike bass performance.

The D-643 Pro and D-643A are designed to be versatile and can be used in a variety of professional audio applications, including live sound reinforcement, studio recording, and installation projects. They come with a number of mounting options, including a standard M10 threaded insert, making them a flexible choice for various rigging configurations.

In summary, the Wharfedale D-643 Pro and D-643A are high-performance 12-inch woofers specifically designed for professional audio applications. Their robust construction, advanced design features, and flexible mounting options make them a reliable and versatile choice for delivering powerful and accurate bass response in various professional audio settings.

The Wharfedale D-643 Pro and D-643A are high-performance subwoofers designed to deliver powerful and accurate bass response in home theaters and music systems. Both models share many similarities, but there are also some key differences that could influence your buying decision. Here are some pros and cons of each subwoofer to help you make an informed choice.

1. Powerful: The D-643 Pro is capable of handling a continuous power of 500W RMS and a peak power of 1000W. This makes it suitable for large home theaters and music systems that require a significant amount of bass.

2. Versatile: It comes with a range of adjustable settings, including variable phase control, a low-pass filter, and a polarity switch, which allow for fine-tuning of the subwoofer's performance to match different systems and room acoustics.

3. Durable: The D-643 Pro has a robust MDF cabinet with bracing and a heavy-duty grille, ensuring that it can withstand the rigors of regular use.

4. Large drivers: It features 12-inch drivers, which provide a wide frequency response range and excellent bass extension.

1. Size: The D-643 Pro is a large subwoofer, measuring 21.5 inches (H) x 17.3 inches (W) x 14.4 inches (D), and weighing 66.1 pounds. This may make it difficult to place in smaller rooms or in situations where space is limited.

2. Complex setup: Due to the various adjustable settings, setting up the D-643 Pro may take some time and effort.

1. Affordable: The D-643A is typically priced lower than the D-643 Pro, making it an attractive option for those on a budget.

2. Compact: It has a smaller footprint than the D-643 Pro, measuring 18.5 inches (H) x 15 inches (W) x 13.5 inches (D), and weighing 48.5 pounds. This makes it more suitable for smaller rooms or for those who prioritize convenience over raw power.

3. Simple setup: The D-643A has fewer adjustable settings compared to the D-643 Pro, making it easier to set up and use.

1. Limited power: The D-643A has a lower power handling capacity, with a continuous power rating of 300W RMS and a peak power of 600W. This may not be sufficient for larger home theaters or music systems that require more bass output.

2. Fewer features: The D-643A does not offer the same level of fine-tuning as the D-643 Pro, which may limit its flexibility in matching different systems and room acoustics.

In conclusion, both the Wharfedale D-643 Pro and D-643A are excellent subwoofers that cater to different needs and budgets. If you're looking for a high-power, versatile subwoofer for large home theaters or music systems, the D-643 Pro is the better choice. However, if you're on a budget or have limited space, the D-643A offers decent performance at a more affordable price point.

If you have the budget and space for a high-power, versatile subwoofer and require excellent bass extension, the Wharfedale D-643 Pro is the recommended option. However, if you're on a budget or have limited space, and don't need the advanced features of the D-643 Pro, the Wharfedale D-643A is a more affordable and compact alternative.
