About the Product

🔊 7-Inch Active Subwoofer

The Harman Kardon Feel 700 uses a 7-inch subwoofer driver engineered to reinforce the low-frequency range of your car audio system. It adds greater depth and punch to music without requiring a large bass enclosure in the boot.

⚡ 125W RMS / 250W Peak Power

With a rated output of 125W RMS and 250W peak, the Feel 700 delivers controlled bass performance suitable for everyday listening as well as more energetic music playback.

🎵 Built-In Class D Amplifier

An integrated Class D amplifier powers the subwoofer, eliminating the need to install a separate external mono amplifier. Class D amplification also allows the system to maintain a compact footprint while providing efficient power delivery.

🚗 Compact Underseat Design

The low-profile enclosure is designed for discreet installation, making the Feel 700 ideal for placement beneath a compatible vehicle seat or in another confined area of the cabin.

This allows you to retain valuable luggage space while still adding a dedicated subwoofer to your car audio setup.

🎶 Deep, Controlled Bass

The Feel 700 is designed to add the missing low-frequency impact that factory car speakers often struggle to reproduce. Bass notes gain greater presence and weight, helping create a fuller and more engaging listening experience.

🎚️ 50Hz–150Hz Frequency Response

With a specified 50Hz–150Hz frequency response, the Feel 700 focuses on the bass frequencies that add body and punch to music and complement your vehicle's existing speakers.

🔌 High-Level Input Support

High-level connectivity makes the subwoofer easier to integrate with compatible factory/OEM audio systems, particularly where conventional RCA pre-outs may not be available.

The product also supports a configuration where two Feel 700 subwoofers can be connected using the high-level input, providing an upgrade path for users looking for greater bass coverage.

🛠️ Adjustable Sound Controls

The integrated amplifier panel provides adjustment controls that allow the subwoofer output to be better matched with the vehicle's existing audio system and listening preference.

Professional tuning after installation is recommended for the best balance between the subwoofer and factory or aftermarket speakers.
