The Driver 1"" Polyimide EAP P400 (8 Ohms) is a high-performance compression driver designed to deliver exceptional clarity, efficiency, and projection in mid–high frequencies. Its polyimide diaphragm and reinforced structure provide smooth, controlled response even at high output levels. Ideal for users seeking accurate vocals, crisp highs, and reliable performance in SQ, PA, or high-output car audio setups.

Key Benefits

• Enhanced clarity and efficiency thanks to the durable polyimide diaphragm.
• Reinforced construction that withstands demanding, long-term use.
• Excellent heat dissipation to reduce distortion and prevent thermal fatigue.
• Accurate and controlled reproduction across mid and high frequencies.
• Compatible with most 1” throat horns and waveguides.
• Perfect for high-performance upgrades in SQ, SPL, or OEM-plus systems.
