Description
Loewe klang sub1 – Compact Wireless Active Subwoofer
The Loewe klang sub1 is a compact, powerful wireless active subwoofer designed to bring deeper bass and greater impact to compatible Loewe televisions.
Combining an innovative six-driver acoustic system, efficient Class-D amplification and Bluetooth aptX Low Latency technology, the klang sub1 delivers impressive low-frequency performance from a remarkably discreet enclosure.
With 160 watts of total music power, the subwoofer is ideal for customers seeking more engaging television sound without installing a large, conventional home cinema subwoofer.
Powerful 160W Bass Performance
The Loewe klang sub1 incorporates a dedicated Class-D amplifier designed for controlled low-frequency reproduction.
Its performance includes:
80W continuous amplifier output
160W total music power
40Hz–100Hz acoustic frequency response
Six-driver bass system
Adjustable subwoofer level
The result is fuller, more dynamic sound for films, television programmes and music.
Innovative Six-Driver Design
The klang sub1 features an unusual bass-driver arrangement designed to minimise unwanted cabinet vibration.
Its acoustic system incorporates:
Two active 4-inch bass drivers
Four passive 4-inch bass radiators
Opposing-driver, motion-compensating design
Compact, closed enclosure with passive membranes
The opposing drivers help reduce cabinet movement, while the passive radiators reinforce low-frequency performance.
This design allows the klang sub1 to deliver substantial bass without requiring a large cabinet.
Wireless Bluetooth aptX Low Latency Connection
The klang sub1 supports Bluetooth 5.0 with aptX Low Latency technology.
When used with the supplied compatible transmitter, the wireless connection is designed to minimise audio delay and maintain synchronisation between television sound and picture.
This makes the subwoofer particularly convenient for modern living rooms, where running an audio cable across the room may be undesirable.
Please note: The subwoofer still requires a mains power connection.
Designed for Compatible Loewe Televisions
The klang sub1 is designed to work with a wide range of Loewe televisions.
Loewe identifies compatibility with:
Loewe televisions from the SL3 chassis generation onwards
Compatible Loewe bild televisions
We. by Loewe SEE televisions
Selected third-party televisions with a suitable variable audio output
Compatibility depends on the television’s audio output and configuration.
The klang sub1 is not a universal wireless subwoofer for every Bluetooth television or soundbar.
Upgrade Your Television to 2.1 Audio
When connected to a compatible television with stereo speakers, the klang sub1 adds a dedicated low-frequency channel.
This creates a 2.1-style listening experience with:
Greater impact from film soundtracks
Fuller music reproduction
More convincing low-frequency effects
Improved bass extension
A more engaging entertainment experience
The subwoofer complements the television’s existing speakers rather than replacing them.
Analogue Audio Connectivity
In addition to its wireless connection, the klang sub1 features a 3.5mm analogue audio input.
This allows connection to compatible televisions or audio equipment with a suitable adjustable analogue output.
For third-party equipment, the output arrangement must be checked to ensure that the subwoofer receives an appropriate bass signal and that its level can be controlled correctly.
Elegant, Space-Saving Design
The klang sub1 features a distinctive low-profile enclosure with a premium acoustic fabric finish and refined Basalt Grey styling.
Its compact construction makes it suitable for discreet placement beside suitable furniture or within a carefully designed entertainment area.
Its low cabinet height is particularly useful in contemporary interiors where space is limited.
