Skytec Compression Driver 40 W - 1” titanium compression tweeter (34 mm thread) 8 Ω

Skytec Compression Driver 40 W - 1” titanium compression tweeter (34 mm thread) 8 Ω

The Skytec Compression Driver 40 W is a 1” titanium diaphragm HF compression driver designed for crystal-clear high frequency reproduction in PA systems, installations and DIY projects. Its high sensitivity (105 dB at 1W/1m) reduces demand on the power amp, while the 25 mm voice coil ensures stability and control during continuous use. It fits directly into standard 1 3/8” (34 mm) threaded horns/reflexes and offers a frequency response of 2–20 kHz into an 8 Ω impedance. Compact in size ( Ø 80 mm × 67 mm ) and weighing 0.7 kg , it is a reliable solution as a spare or for building two-way systems with HF cutoff from ~2 kHz.

Main features

• 1” titanium diaphragm : fast attack and good treble extension.
• High efficiency : 105 dB (1W/1m) for high SPL with low power.
• 1 3/8” (34 mm) threaded connection : universal compatibility with threaded speakers (horn not included).
• 25mm coil and 40W power : stable performance in voice and music applications.
• Impedance 8 Ω : easy integration with standard passive filters.
• Range 2–20 kHz : ideal as a treble path in 2-way systems.
• Compact design : Ø 80 mm × 67 mm , 0.7 kg .

Product benefits

• More pressure with fewer watts : its 105 dB sensitivity allows you to work with small stages or maintain a greater dynamic range.
• Clear and defined highs thanks to the titanium diaphragm and 25 mm coil.
• Quick mount with standard 1 3/8” (34 mm) thread, without adapters on most trumpets.
• Direct replacement for active/passive enclosures using 1” threaded HF drivers.

Use cases

• Replacing the tweeter motor in two-way PA boxes.
• Fixed installations (halls, temples, schools) that require high voice intelligibility.
• DIY projects combining it with 8”–15” woofer and suitable passive crossover (≥2 kHz).

Compatibility and installation

Uses 1 3/8” (34 mm) threaded speakers/reflectors . The driver does not include a horn. Respect a minimum cutoff around 2 kHz depending on the filter and system design, avoiding operating below the specified range. Connect respecting polarities and, if necessary, attenuate using the L-pad to balance the level with respect to the woofer.

Frequently Asked Questions

• Is the trumpet included? No, the driver is sold. The threaded trumpet is purchased separately.
• What thread does it use? Standard 1 3/8” (34 mm) , compatible with most threaded speakers on the market.
• Does it work with 4 Ω? No, this model is 8 Ω . Check the impedance of the filter/stage before replacing.
