Active underseat car subwoofer

The FEEL 700 is designed to bring more impactful bass to an existing in-vehicle audio system without taking up boot space. Its underseat form factor keeps installation discreet.

Harman Kardon's clean aesthetic design

The FEEL 700's clean corner and edge treatments maximise internal air volume, which directly benefits bass performance. The grille is wrapped in automotive-grade fabric so it sits naturally alongside car carpets. The fabric edges are pillowed sub-flush to the aluminium frame to protect the grille from second-row passengers' feet, and an aluminium badge finishes the look towards the bottom edge.

Powerful bass, ultra-compact space

The FEEL 700 reproduces deep, powerful bass while occupying minimal space beneath a seat.

Easy upgrade with series wiring capability

A second FEEL 700 (sold separately) can be daisy-chained to the first for greater bass output. No complex wiring is needed, and each unit remains independently adjustable.

Efficient Class D amplifier

The built-in Class D amplifier produces minimal heat and draws little current from the vehicle's electrical system.

Crossover control

The adjustable low-pass filter (50 Hz – 150 Hz) lets you control how much upper and mid-bass the FEEL 700 reproduces, helping it blend smoothly with the rest of your speakers — such as the Harman Kardon Flow 600CF component speakers.

Flexible EQ adjustments

The gain control sets the FEEL 700's output level relative to your other speakers. The bass boost (0 to +12 dB) lets you compensate for peaks or dips in bass frequencies caused by your car's acoustic environment.

Line-level and high-level inputs

Both line-level and high-level inputs are included, so the FEEL 700 can be connected to either an aftermarket head unit or a factory system.

Die-cast aluminium enclosure

The all-die-cast aluminium enclosure keeps the design ultra-compact while supporting the acoustic performance needed for quality bass reproduction.
