Skytec SP800 - 8” (20 cm) 8 Ω speaker for woofer replacement

Skytec SP800 - 8” (20 cm) 8 Ω speaker for woofer replacement

The Skytec SP800 is an 8” (20cm), 8Ω woofer designed as a reliable replacement for PA speakers, installations and DIY projects. It features a rigid suspension that controls cone displacement and a vented magnet for improved heat dissipation, together with a 38mm (1.5”) voice coil . Its nominal power of 90W and peak of 200W , combined with a sensitivity of 89dB (1W/1m) and a response of 65–4,000Hz , deliver balanced performance in the bass and mid-bass regions. Installation is simple thanks to the spade (Faston) terminals and standard dimensions: cutout diameter 180mm , mounting depth 80mm , outer diameter ≈ 210mm and total height 87mm . Approximate weight of the assembly: 1.45kg . Finished in black.

Main features

• 8” (20 cm), 8 Ω : compatibility with most passive enclosures and 8 ohm power amplifiers.
• 90W nominal / 200W max : dynamic range suitable for compact PA, monitors and installations.
• Sensitivity 89 dB (1W/1m) and response 65–4,000 Hz : clear bass and midrange in 2-way systems.
• 38mm (1.5”) coil and vented ferrite magnet (20 oz) for thermal reliability.
• Rigid suspension : less distortion at high levels and better cone control.
• Spade terminals : quick and secure connection for replacements.
• Standard mounting : cutout 180 mm, depth 80 mm, outer diameter ~210 mm.

Product benefits

• Direct replacement that avoids modifications to the 8” enclosure.
• Reliability in continuous use thanks to the ventilated magnet and robust suspension.
• Consistent bass and mid-bass performance for vocals, guitars, keyboards and general reinforcement.
• Easy installation with Faston connections and universally compatible measurements.

Use cases

• Replacing woofers in 8” passive boxes.
• DIY construction of 2-way systems combining it with tweeter/compression driver.
• Maintenance of rental equipment and mobile sound.

Compatibility and installation

Confirm that your system is operating at 8 ohms and that the dimensions ( 180 mm cutout , 80 mm depth ) fit the speaker cabinet. Apply gasket to ensure a tight seal between the chassis and the front panel and use appropriate hardware. In two-way systems, maintain the original crossover or adjust the crossover frequency if you modify the design.

Frequently Asked Questions

• Can it be used as a dedicated subwoofer? No. Its usable range starts at 65 Hz ; it functions as a two-way bass/mid-bass woofer .
• Can I replace a 4 Ω speaker with this 8 Ω speaker? This will change the overall impedance of the system. Use this model if the speaker is designed for 8 Ω .
• What type of connection does it use? Spade terminals (Faston) for quick connection.
