NVX XSP525

The Woofer

In order to achieve the crisp and honest sound that sets the X-Series apart from the competition, the NVX engineers set out to build a midwoofer with precise linear movement and minimal mechanical damping. As a result of the extensive research and development process, this midwoofer features materials, technologies, and sound quality unique within the industry:

• Milled Egyptian Papyrus Pulp Cone
• Ultra-lightweight & stiff material for spectacular accuracy
• Rich, natural tonal quality


• Low-Damping Rubber Surround
• Improves responsiveness
• Optimized for use with high-quality amplifiers


• Copper Shorting Sleeve
• Improves power delivery to the voice coil
• Reduces inductive distortion
• Improves linear movement of cone
• Improves high-end extension
• Effectively dissipates heat


• Copper Shorting Sleeve
• Reduces compression of the motor structure
• Improves cone control
• Reduces back wave interference
• Reduces basket resonations

General Features:

• 5-1/4" X-Series Mid-Bass Car Drivers
• Power Handling:
• Peak: 160 watts per pair / 80 watts each
• RMS: 80 watts per pair / 40 watts each
• Finely Milled Pulp and Egyptian Papyrus Fiber cone material is stiff yet lightweight
• Low Damping Rubber speaker surround maintains linear movement better than any other material
• Copper Shorting Sleeve placed in the air gap between the pole piece and the voice coil former reduces inductance
• Shorting Sleeve improves power delivery to the voice coil, decreases inductive distortion and improves cone linearity
• Low Turbulence Cast Aluminum Basket improves airflow to reduce compression of the motor structure
• Relatively soft spider to reduce unwanted mechanical stiffness
• Speaker housing designed to improve cone control and reduce back-wave interference
• 3-dimensional cast design dramatically increases the strength and rigidity of the basket
• Designed to perform optimally in a real car environment
• 4 ohms impedance
• Frequency response: 75-4,000 Hz
• Top-mount depth: 2-3/4"
• Sensitivity: 90dB
• Authorized Internet Dealer
• 1-year Manufacturer's Warranty
