Subwoofer with open baffle

A subwoofer should not make things louder, but deeper. The Topline XL subwoofers take over the range below 33 Hz and reach down linearly to 17 Hz, without the DSP having to help. Organ, double bass and the space of large recordings gain weight and contour.

Because the Bob XL hands over the lowest octave, the midrange and treble can unfold freely in their own range. The sound becomes not only deeper, but also clearer.

Color me impressed.

more than two square meters of diaphragm area

Built for large rooms

Each subwoofer holds eight handmade 18-inch drivers in a fully stabilized cabinet with an open baffle. Together they offer more than two square meters of diaphragm area. The diaphragms therefore barely need to move and stay within their linear range.

A DSP-controlled amplifier with 3000 watts drives each subwoofer. The DSP adapts the bass to your room. The subwoofers can be set up in stereo or mono.

Construction

How the Topline XL Subwoofer is built

Open baffle

The drivers work without a closed box. The bass stays fast and free of compression.

Large diaphragm area

More than 2 m² per subwoofer from eight 18-inch drivers. Small excursion, low distortion.

Stabilized cabinet

A fully stabilized special cabinet keeps the drivers calm.

DSP control

3000 watts per subwoofer, adapted to your room via DSP.

Linear to 17 Hz

Without level drop and without subsequent equalization.

Stereo or mono

The setup follows your room and listening position.

The extension to the Bob XL+

With the Topline XL subwoofers, the Topline Bob XL becomes the Bob XL+. The subwoofers take over the range below 33 Hz and reach down linearly to 17 Hz, without the DSP having to lift the frequency response afterwards.

More foundation, more clarity

The lowest octave gains color and contour. Because the Bob XL hands over this range, the midrange and treble can unfold freely in their own range. The sound becomes not only deeper, but also clearer.

Eight 18-inch drivers in an open baffle

Each subwoofer holds eight handmade 18-inch drivers with more than two square meters of diaphragm area, in a fully stabilized special cabinet with an open baffle. A DSP-controlled amplifier with 3000 watts drives each subwoofer. Stereo or mono setups are possible.
