Hertz SV200L 8" SPL Woofers (Pair)

The Hertz SV200L is an 8-inch SPL woofer designed for car audio systems that need strong midbass output and high sound-pressure capability. Sold as a pair, these 4-ohm drivers are intended for enthusiasts building a louder, more dynamic speaker system. Their operating range supports use where impactful low-to-mid frequency performance is needed.

This model is suited to custom installations, SPL-oriented builds, and upgraded door, kick-panel, or enclosure applications with adequate mounting space. With 250 watts continuous power handling per woofer, it can be paired with properly matched external amplification. Its 94.5 dB sensitivity helps it produce substantial output from the available amplifier power.

The SV200L uses Hertz V-cone technology, an exponential cone profile designed to support broad off-axis dispersion and mid-frequency detail. Its ultra-light non-pressed paper cone is blended with cotton fiber to balance low-frequency response with responsive behavior. A lossless polymer rubber surround supports cone travel and durability.

Thermal and mechanical design elements include a double-layer pure-copper voice coil wound on a KSV former, high-permeability steel plates, and a vented bottom plate. These features are engineered to maintain magnetic flux consistency while helping dissipate heat. A high-density ferrite magnet provides the motor strength needed for its SPL-focused application.

Use the SV200L as part of a properly planned multi-speaker system with amplification, crossover settings, and mounting locations chosen for the vehicle and listening goals. Its 45 Hz to 4.5 kHz frequency response makes it a dedicated woofer rather than a full-range replacement speaker. For a balanced system, pair it with compatible high-frequency drivers and appropriate filtering.

Key Features

• 8-Inch SPL Woofer: Designed for high-output car audio applications.
• 250W Continuous Power: Handles substantial amplifier power per woofer.
• 4-Ohm Impedance: Works with compatible 4-ohm amplifier channels.
• V-Cone Profile: Supports off-axis dispersion and midrange detail.
• Copper KSV Voice Coil: Built for thermal and mechanical capability.
• Ferrite Magnet Motor: Uses a high-density flux ferrite magnet.

Design & Installation

The SV200L combines a high-density ferrite magnet with high-permeability plates, a vented bottom plate, and high-current tin-plated terminals. Its cone is made from ultra-light non-pressed paper mixed with cotton fiber, while the surround uses lossless polymer rubber. Each woofer weighs 2.32 kg (5.1 lb).

Plan mounting around the published 209 mm outer diameter, 178 mm mounting diameter, and 91 mm mounting depth dimensions. Wire each driver as a 4-ohm load and select amplification appropriate for its 250-watt continuous power rating. Because this is a woofer with a 45 Hz to 4.5 kHz frequency response, use suitable crossover settings and compatible high-frequency speakers for full-range system coverage.
