Skytec SP1200 - 12” (30 cm) 4 Ω speaker for woofer replacement

Skytec SP1200 - 12” (30 cm) 4 Ω speaker for woofer replacement

The Skytec SP1200 is a 12” (30cm), 4Ω woofer designed as a reliable replacement for PA, mobile sound and installation speakers. It features a rigid suspension for precise cone control, a vented magnet for improved heat dissipation and a 38mm (1.5”) voice coil . Its 200W RMS (400W max) capacity, 96dB (1W/1m) sensitivity and 50–3500Hz frequency response make it a balanced bass and mid-bass solution for two-way systems. Installation is simple with spade (Faston) terminals and standard dimensions of 280mm cutout diameter , 113mm mounting depth and approx. 311mm outside diameter . It is finished in black and weighs 2.55kg .

Main features

• 12” (30 cm), 4 Ω : compatible with amplifiers and enclosures sized at 4 ohms.
• 200W RMS / 400W max : Sufficient dynamic range for compact PA, monitors and installations.
• Sensitivity 96 dB (1W/1m) : good performance at moderate power.
• Response 50–3,500 Hz : Effective bass and midrange coverage for 2-way systems with dedicated driver/tweeter.
• 38mm (1.5”) coil and vented magnet : better thermal management and reliability in continuous use.
• Rigid suspension : cone displacement control and lower distortion at high levels.
• Spade terminals (Faston) : quick and secure connection for replacements and assemblies.
• Standard mounting dimensions : cut-out 280 mm, depth 113 mm, outer ~311 mm for easy integration.

Product benefits

• Direct replacement for restoring 12” speakers without modifying the cabinet or baffle cutout.
• Reliability on tours, rentals and fixed installations thanks to the vented coil/magnet assembly and robust suspension.
• Consistent sound in the bass-midrange, ideal for vocals, rhythm guitar, keyboards, and general reinforcement.
• Hassle-free installation with Faston terminals and standard hardware.

Use cases

• Replacement of woofers in 12” passive boxes (PA, stage monitors, installations).
• DIY projects on two-way systems combining it with a compression driver/tweeter.
• Maintenance of rental parks and mobile DJ equipment.

Compatibility and installation

Verify that the system supports a 4 Ω load and that the cutout diameter (280 mm) and mounting depth (113 mm) fit the enclosure. Ensure tightness between the chassis and the speaker, and use appropriate hardware. For two-way systems, keep the manufacturer's original crossover or adjust the crossover frequency if you modify the system design.

Frequently Asked Questions

• Can it be used as a dedicated subwoofer? It's not a very low-frequency sub. Its useful range starts around 50 Hz ; use it as a woofer in two-way systems.
• Can I replace an 8 Ω speaker with this 4 Ω speaker? Not directly: that would change the overall impedance and amplifier load. Use this model only if the speaker is designed for 4 Ω.
• Is the magnet ferrite? Yes, it's a vented ferrite magnet to improve heat dissipation.
