B&C Speakers 8FG51-8 8-inch Mid Bass Woofer Cone WP Waterproof Front Side 250 Wrms 500 Watt Peak Audio Speaker 8 ohm Ventilated 2 in. Voice Coil Gap

• FEATURES : This speaker driver offers a powerful 500-watt continuous program capacity and features a 2-inch copper voice coil for efficient performance across a 50 to 4000 Hz frequency range. With a sensitivity of 93 dB, it delivers strong output, while the shorting copper cap enhances high-frequency response. Additionally, its ventilated voice coil gap helps reduce power compression, ensuring consistent sound quality during extended use.

• SPECIFICATIONS : This 8-inch speaker driver is built for reliable mid-bass performance, 8-ohm nominal impedance & 500 W continuous power handling. It operates across a frequency range of 50 Hz to 4000 Hz with sensitivity of 93 dB, ensuring clear and efficient output. The 2-inch copper voice coil is wound to a depth of 0.65 inches on a durable glass fibre former, supported by a magnetic gap depth of 0.31 inches & flux density of 1.15 Tesla. Its waterproof-treated cone enhances durability.

• PARAMETERS : This speaker driver is designed for efficient low-frequency output, featuring a 49 Hz resonance, 220 cm² piston area, and 6.5 mm peak excursion. With a Qts of 0.32 and EBP of 144 Hz, it's ideal for vented enclosures. Its 35 g moving mass, 12.9 Tm motor strength, and 5.1-ohm resistance ensure controlled performance, while the 0.7% efficiency and 20 dm³ compliance volume support dynamic bass response.

• DESIGN : This speaker driver features a roll-shaped surround and an exponential cone design, supported by a single spider for stable movement. It uses a ferrite magnet with a T-pole structure to ensure consistent magnetic performance. The woofer cone is treated with WP waterproofing on the front side for added durability. Designed for optimal bass response, it performs best in a 17 dm³ (0.6 ft³) enclosure tuned to 52 Hz.
