2. Design and Build of JBL Bar 2.1 Deep Bass MK2 – Low‑Profile Soundbar with Wireless Subwoofer
The JBL Bar 2.1 Deep Bass MK2 (9) features a sleek, low‑profile soundbar that measures 965 x 56 x 85 mm (38 inches wide). Its slim height (56mm) allows it to fit comfortably in front of most TVs without blocking the screen.
The soundbar of the JBL Bar 2.1 Deep Bass MK2 (10) is constructed from durable materials with a matte black finish that resists fingerprints and blends into any home theatre setup. The front grille houses the drivers and a subtle LED display that shows volume, input source, and bass level.
The wireless subwoofer on the JBL Bar 2.1 Deep Bass MK2 (11) measures 240 x 240 x 379 mm and weighs 5.61 kg. It features a down‑firing 6.5‑inch active driver that projects bass through the bottom, allowing flexible placement anywhere in the room.
The subwoofer on the JBL Bar 2.1 Deep Bass MK2 (12) connects wirelessly to the soundbar, eliminating the need for a long audio cable. The build quality of the JBL Bar 2.1 Deep Bass MK2 (13) is solid, and the subwoofer’s compact footprint makes it easy to tuck beside a sofa or entertainment unit.
3. Audio Performance – 300W of Deep Bass and Clear Cinematic Sound
The JBL Bar 2.1 Deep Bass MK2 (14) delivers 300W total power (100W from the soundbar and 200W from the subwoofer). The soundbar’s 4 race‑track drivers and 2 x 1‑inch tweeters on the JBL Bar 2.1 Deep Bass MK2 (15) produce clear dialogue, crisp highs, and a wide soundstage.
The 6.5‑inch subwoofer provides deep, punchy bass that can “rattle floors at maximum settings,” according to reviewers. The frequency response ranges from 40Hz to 20kHz, ensuring you feel the rumble of explosions and the thump of music.
Dolby Digital decoding and JBL Surround Sound processing create an immersive, cinema‑like experience without requiring additional surround speakers.
The soundbar’s broad audio dispersion fills the room, making it ideal for movies, TV shows, sports, and music.
The dedicated remote control includes three distinct bass levels, allowing you to adjust the low‑end intensity to your preference – from subtle enhancement to full‑powered rumble.
While the JBL Bar 2.1 Deep Bass MK2 (20) lacks object‑based audio (Dolby Atmos, DTS:X) and cannot be expanded with rear satellite speakers, it excels at delivering powerful, engaging sound for its price point. This remarkable audio performance is truly impressive.
4. Connectivity – HDMI ARC, Optical, Bluetooth, and More
The JBL Bar 2.1 Deep Bass MK2 (21) offers a practical selection of ports:
HDMI input and HDMI output (with Audio Return Channel – ARC) – allows you to connect a source device and pass video to your TV while playing audio through the soundbar. HDMI ARC enables the TV to send audio back to the soundbar from built‑in apps or broadcast TV.
Optical input – for connecting older TVs without HDMI ARC.
AUX input (3.5mm) – for smartphones, tablets, or MP3 players.
USB Type‑A port – for playing music from flash drives (formats: MP3, WMA, etc.).
Bluetooth 4.2 – for wireless music streaming from any compatible device, including Android smartphones. The connection is stable and easy to pair.
For Android users, the Bluetooth integration is seamless within the Android ecosystem. The system does not include Wi‑Fi or streaming services like Apple AirPlay or Google Chromecast, so music streaming is limited to Bluetooth. This versatile connectivity is a major advantage.
5. Setup and Controls – Plug‑and‑Play Simplicity with Front LED Display
The JBL Bar 2.1 Deep Bass MK2 (23) is designed for plug‑and‑play simplicity. The soundbar and subwoofer pair wirelessly automatically when powered on.
Connect the JBL Bar 2.1 Deep Bass MK2 (24) to your TV via HDMI ARC (or optical), plug in the power cords, and you are ready. The included remote control provides all essential functions: power, volume, input selection, bass level (3 settings), and sound mode adjustments.
The front LED display shows the current volume, input source, and bass level, making it easy to navigate settings. Physical buttons on the soundbar (power, volume, input) offer an alternative control option. The system has no companion app or advanced EQ customisation, which keeps the experience straightforward but limits fine‑tuning.
