8835 ROLA Field Coil Speaker

The ROLA 8835 12-inch Field Coil Speaker is a high-performance audio component designed for professional sound reinforcement applications. This speaker boasts a powerful neodymium magnet and a 12-inch paper cone woofer, capable of delivering clear and accurate bass response. The speaker's voice coil is a field coil design, which allows for greater efficiency and improved power handling compared to typical electromagnetic voice coils.

The 8835's frequency response ranges from 35 Hz to 5 kHz, making it an excellent choice for reinforcing mid-range frequencies in various sound systems. Its sensitivity is rated at 95 dB, allowing it to produce a significant volume level even when driven by relatively low-power amplifiers.

This speaker features a rugged, Baltic birch plywood enclosure, which is both lightweight and durable. Its dimensions are 24.5 inches (H) x 15.5 inches (W) x 13 inches (D), and it weighs approximately 31 pounds, making it suitable for mobile applications. The 8835 also includes a 1.5-inch voice coil, a 10-ohm impedance, and a 300-watt power handling capacity.

The ROLA 8835 is designed to meet the demands of professional sound engineers and live sound applications. Its field coil design, combined with its powerful neodymium magnet and durable enclosure, ensures reliable and consistent performance night after night. Additionally, its mid-range frequency response and high sensitivity make it a versatile addition to any sound system setup.

The Rola 8835 12-inch field coil speaker is a popular choice among audio enthusiasts due to its unique design and high-fidelity sound. However, like any other audio equipment, it has its own set of pros and cons that are worth considering before making a purchase.

Pros:

1. High Sensitivity: The Rola 8835 has a high sensitivity of 101 dB, making it an efficient speaker that can produce a relatively loud sound even with low-power amplifiers.

2. High-Fidelity Sound: Field coil speakers, like the Rola 8835, are known for their high-fidelity sound. They produce a more natural and detailed sound compared to their inductor counterparts.

3. Low Distortion: The Rola 8835 has a low distortion rating, which means that it can reproduce sound accurately and faithfully without adding unwanted noise.

4. Durable: The speaker's rugged design makes it suitable for use in harsh environments, making it a popular choice among DJs and live sound engineers.

Cons:

1. Complex Setup: The Rola 8835 requires a more complex setup compared to conventional speakers. It requires a transformer to match the impedance of the speaker to the amplifier.

2. Limited Frequency Response: The speaker's frequency response is limited compared to modern speakers. It has a frequency response range of 40 Hz to 15 kHz, which may not be suitable for all types of music and audio applications.

3. Limited Availability: The Rola 8835 is no longer in production, and spare parts and replacement speakers may be difficult to find.

4. Expensive: Due to their unique design and high-fidelity sound, field coil speakers like the Rola 8835 are often more expensive compared to conventional speakers.

Conclusion:

The Rola 8835 12-inch field coil speaker is a high-quality audio equipment that offers superior sound quality and durability. However, its complex setup, limited frequency response, and high cost may not make it the best choice for all audio applications. It is best suited for audio enthusiasts and professionals who require high-fidelity sound and are willing to invest in a more complex and expensive setup.

Recommendation:

If you are looking for a high-fidelity speaker with a more conventional design and a wider frequency response range, I would recommend considering a high-end dynamic speaker or a planar magnetic speaker. These types of speakers offer excellent sound quality and are more widely available and affordable compared to field coil speakers. However, if you are set on a field coil speaker and can afford the complex setup and high cost, the Rola 8835 is an excellent choice.
