Skytec SP1500 - 15” (38 cm) 8 Ω speaker for woofer replacement

Skytec SP1500 - 15” (38 cm) 8 Ω speaker for woofer replacement

The Skytec SP1500 is a 15” (38 cm), 8 ohm woofer designed as a direct replacement for PA speakers, installations and DIY projects. It combines rigid suspension for precise cone control, a vented ferrite magnet for improved heat dissipation and a 50 mm (2”) voice coil . Its 150 W continuous (400 W max) handling, 98 dB (1 W/1 m) sensitivity and 40–3,500 Hz frequency response deliver solid bass and mid-bass in two-way systems. Installation is simple thanks to spade (Faston) terminals and standard dimensions: 370 mm cutout diameter , 130 mm mounting depth and approximate external dimensions of 386 × 153 mm . Speaker weight ≈ 4.85 kg . Black finish.

Main features

• 15” (38 cm), 8 Ω : compatibility with most 8 ohm amplifiers and enclosures.
• 150W RMS / 400W Max : Reliable performance for compact PA, monitors and installations.
• Sensitivity 98 dB (1W/1m) : good efficiency with moderate power.
• Response 40–3,500 Hz : Effective bass and mid-bass coverage in 2-way systems.
• 50 mm (2”) coil and vented magnet : greater thermal resistance in continuous use.
• Rigid suspension : cone displacement control and lower distortion at high levels.
• Spade terminals for quick and secure connection during replacements.
• Standard mounting : cut-out 370 mm, depth 130 mm, outside ~386 × 153 mm.

Product benefits

• Direct replacement without baffle modifications in most 15” enclosures.
• Reliability thanks to the ventilated coil/magnet assembly and robust suspension.
• Consistent low-mid performance for vocals, keyboard, rhythm guitar and general reinforcement.
• Easy installation with standard screws and Faston terminals.

Use cases

• Replacement of woofers in 15” passive PA speakers and stage monitors.
• DIY construction of 2-way systems combining it with a high-frequency motor/tweeter.
• Maintenance of rental equipment and mobile sound.

Compatibility and installation

Confirm that your system is operating at 8 ohms and that the crossover diameter (370 mm) and depth (130 mm) match the enclosure. Apply gasket to ensure a tight seal between the chassis and the speaker, 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 response starts at around 40 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 and load of the amplifier. Use it if the speaker is designed for 8 Ω .
• What is the mass of the magnet? Approximately 50 oz (≈ 1.42 kg ), vented ferrite .
