Skytec SP1000 - 10” (25 cm) 4 Ω speaker for woofer replacement

Skytec SP1000 - 10” (25 cm) 4 Ω speaker for woofer replacement

The Skytec SP1000 is a 10” (25cm), 4Ω speaker/woofer designed as a reliable replacement for PA speakers, mobile sound and DIY projects. It features rigid suspension for precise cone control, a vented magnet for improved heat dissipation and a 38mm (1.5”) voice coil capable of handling 150W RMS (300W max) . With a sensitivity of 93dB (1W/1m) and a frequency response of 55–4,000Hz , it delivers defined bass and midrange for sound reinforcement applications. Easy to install with spade (Faston) terminals and standard dimensions: 230mm cutout diameter , 95mm mounting depth and approx. 258mm outer diameter . It is finished in black and weighs 2.3kg .

Main features

• 10” (25 cm), 4 Ω : Compatible with cabinets and amplifiers configured at 4 ohms.
• 150W RMS / 300W max : sufficient dynamic range for compact PA and monitors.
• 38mm (1.5”) coil and vented magnet : better thermal management and reliability in continuous use.
• Rigid suspension : greater control of cone movement and less distortion at high levels.
• Sensitivity 93 dB (1W/1m) : good performance at moderate power.
• Response 55–4,000 Hz : Effective bass and midrange coverage for 2-way systems with tweeter driver.
• Spade terminals : quick and secure connection for replacements and assembly.
• Standard dimensions : cut-out 230 mm, depth 95 mm, exterior ~258 mm, for easy integration into most 10” enclosures.

Product benefits

• Direct and economical replacement for restoring 10” boxes without modifying the enclosure.
• Reliability on tours and rentals thanks to the vented coil/magnet assembly and robust suspension.
• Consistent sound in the bass-midrange, ideal for vocals, rhythm guitar, keys, and general reinforcement.
• Hassle-free installation with Faston terminals and widely compatible mounting dimensions.

Use cases

• Replacement of woofers in 10” passive boxes (PA, stage monitors, fixed installations).
• DIY two-way projects using a dedicated compression driver/tweeter for high frequencies.
• Maintenance of rental parks and mobile DJ equipment requiring standard and durable components.

Compatibility and installation

Check that your speaker cabinet can handle a 4 ohm load and that the cutout diameter (230 mm) and depth (95 mm) match the enclosure. Use appropriate hardware and ensure a tight seal between the chassis and the speaker cabinet. For a two-way system, keep the original manufacturer's crossover or adjust the crossover if necessary.

Frequently Asked Questions

• Can I mount it in an 8 Ω cabinet? Not individually: this model is 4 Ω . In systems with multiple speakers, series/parallel connections could be used to achieve the desired impedance, always taking into account the amplifier's final load.
• Can it be used as a dedicated subwoofer? Its usable response starts at 55 Hz ; it functions as a 10-inch woofer for bass and mid-bass, not as a very low-frequency sub.
• Do I also need to replace the tweeter or crossover? For replacements, keep the original tweeter and crossover if they were sized for a 10" 4 ohm woofer with a similar crossover. If you change the system design, adjust the crossover accordingly.
