D2 HF Compression Driver — Setup, Review & Best Use India

What Is the D2 HF Compression Driver?

The D2 HF Compression Driver is a high-frequency transducer designed specifically for professional PA speaker cabinets. Unlike a regular tweeter that sits in free air, a compression driver screws directly onto a horn, using acoustic compression to dramatically increase efficiency and projection. The D2 driver is one of the most widely used compression drivers in DJ PA cabinets across India, and Punishka Trading in Rohini, Delhi stocks it at wholesale prices for cabinet builders and event sound companies.

D2 Driver Technical Specifications

• Throat Size: 1.4-inch (35mm) throat
• Magnet Type: Neodymium — lightweight and powerful
• Power Handling: 100W program / 50W continuous
• Frequency Response: 1kHz–18kHz
• Impedance: 8 ohms
• Sensitivity: 104–107 dB/W/m (with horn)
• Voice Coil: 1.4-inch titanium diaphragm

Best Horn Pairings for the D2 Driver

The D2 driver must always be used with a matching horn. The most common and effective horn choices in India are:

• 90x40 degree radial horn — ideal for most PA tops and full-range cabinets
• 60x40 degree horn — tighter dispersion for line array elements and long-throw applications
• Exponential horn — maximum efficiency for outdoor high-SPL applications

Always match the horn throat diameter to the D2's 1.4-inch throat for correct coupling.

D2 Driver vs DE800 Tweeter — Which to Choose?

Both are available from Punishka Trading, but they serve slightly different purposes:

• D2 Compression Driver: Better for mid-high applications starting at 1kHz. Handles more power, better for large PA cabinets and outdoor use. Must be crossed over above 1kHz.
• DE800 Neodymium Tweeter: Better for high-frequency air and sparkle above 3kHz. Simpler to wire into a passive crossover network plate. 120W program handling.

For large DJ PA cabinets with active crossovers, the D2 is the preferred choice. For budget cabinets with passive network plates, the DE800 is often more practical.

How to Mount and Wire the D2 Driver

1. Select the correct horn for your cabinet dispersion requirement
2. Apply a thin gasket or foam seal between driver and horn throat flange
3. Screw the D2 driver onto the horn throat — typically 4 bolts
4. Mount the horn+driver assembly in the cabinet cutout
5. Connect the positive terminal of the D2 to the HF output of your crossover
6. Never run the D2 without a high-pass crossover — set crossover at minimum 1kHz (12dB/octave slope or steeper)

Use Cases for the D2 Driver

• Full-range PA tops (paired with 12" or 15" woofer)
• Mid-high cabinets in 3-way systems
• Line array elements for medium throw
• Portable event PA boxes
