Marshall WOBURN III｜Flagship Home Bluetooth Stereo Speaker
A Bluetooth stereo speaker that fills the room
Marshall WOBURN III is a Bluetooth stereo speaker from Marshall, featuring a Bluetooth 5.2 wireless connection architecture, 35–20,000 Hz Frequency Response, and 100.5 dB @ 1 m Maximum SPL, plus a redesigned wide stereo soundstage and Dynamic Loudness volume compensation technology.
Whether you want a more immersive music experience in the living room, better and fuller external sound for your TV, or richer bass and a wider soundstage in a studio, suite, or open space, WOBURN III gets you up and running quickly with a more direct connection.
Compared with traditional small home speakers that focus only on a single sweet spot, Marshall WOBURN III uses outward-angled tweeters and an updated waveguide design to deliver wider sound coverage; compared with smaller speakers in the same series, its advantages are a larger cabinet, more amplifier power, and HDMI Input TV connectivity, which is rare in home Bluetooth speakers.

Who is Marshall WOBURN III for?
Marshall WOBURN III Core Technologies and Features
-
Redesigned wide stereo soundstage：The third-generation home series has been retuned for sound dispersion, using outward-angled tweeters and updated waveguides to create a wider, more enveloping soundstage without locking you into a single listening position.
-
Marshall signature big-dynamic sound：Officially positioned as Marshall signature sound that fills the room and delivers a home-shaking experience, ideal for home listening that needs thick bass, strong presence, and powerful projection in larger spaces.
-
Dynamic Loudness volume compensation：Built-in Dynamic Loudness automatically adjusts tonal balance based on playback volume, keeping bass, treble, and overall sound consistent and full at different volume levels.
-
Multi-amplifier independent drive architecture：Uses one 90W Class D woofer amplifier, two 15W Class D midrange amplifiers, and two 15W Class D tweeter amplifiers to match the multi-driver design and improve control and output efficiency.
-
Bass-reflex cabinet design：The cabinet uses a bass-reflex structure to help extend low frequencies and increase overall energy, making it suitable for living rooms, open spaces, and environments that need more bass impact.
-
Bluetooth 5.2 and next-gen Bluetooth readiness：Supports Bluetooth 5.2 and is marked Ready for Bluetooth LE Audio, so it is prepared for next-generation Bluetooth features through future updates.
-
OTA wireless update support：Use the Marshall Bluetooth app for OTA software updates so the speaker can keep receiving the latest features and system improvements.
-
Intuitive physical controls on the unit：The top panel provides source selection, volume, bass, treble, play/pause, previous/next, and power, so you do not need your phone every time for basic control.
-
Flexible wired and wireless connectivity：In addition to Bluetooth playback, it also offers 3.5 mm Input, RCA Input, and HDMI Input for phones, players, phono preamp output devices, or TVs.
-
HDMI Input TV integration advantage：WOBURN III is especially well suited for TV connection within the series, and once connected by HDMI, it offers a more complete experience than a typical music-only Bluetooth speaker.
-
Advanced app control：You can fine-tune sound settings and manage updates through the Marshall Bluetooth app; Marshall also states that EQ can still be controlled directly on the speaker without the app.
-
Classic Marshall home design language：Retains the brand’s signature logo, brass control knobs, and rock-inspired look, combining home décor appeal with the presence of a serious audio device.
-
Designed in Sweden and engineered in Sweden：The product is designed and engineered in Sweden and made in China, balancing brand character with manufacturing consistency.
Redesigned Wide Soundstage Technology
- The third-generation home series has been retuned for spatial depth, with the core focus on a wider stereo soundstage than the previous generation.
- Outward-angled tweeters and an updated waveguide design help spread sound more evenly, reducing the need to sit in the exact center for the best experience.
- Marshall says the sound width can maintain a stable presence throughout the room, making it suitable for shared listening or open-space playback.
Dynamic Loudness Volume Compensation
- Built-in Dynamic Loudness automatically corrects tonal balance based on playback volume, preventing thin sound at low volume and overly emphasized frequencies at high volume.
- It is especially useful for everyday home use, since daytime, nighttime, movie watching, background playback, and party volume are often different.
- This design helps music stay clear, full, and easy to listen to across a wide range of volume levels.
Multi-Amplifier and Multi-Driver Configuration
- The low end is driven by one 90W Class D amplifier, delivering the main bass energy and room impact.
- The mids are driven by two 15W Class D amplifiers, and the highs are also driven by two 15W Class D amplifiers, creating a more detailed division of labor across frequencies.
- This setup helps balance vocals, instrument detail, and bass impact, making it suitable for pop, rock, electronic, and film content.
Bluetooth 5.2 and OTA Update Experience
- Supports Bluetooth 5.2 for a stable wireless streaming experience, with a Bluetooth range of up to 10 m.
- The product is marked Ready for Bluetooth LE Audio, meaning the hardware is prepared for next-generation Bluetooth features.
- Use the Marshall Bluetooth app for OTA updates so features and firmware stay current.
3.5 mm, RCA, HDMI Input Connectivity Flexibility
- Provides 3.5 mm Input for quick connection to portable players, computers, or devices with headphone output.
- Provides RCA Input for easy connection to audio equipment with analog output.
- Provides HDMI Input so WOBURN III can connect directly to a TV, expanding its use beyond music to film and TV entertainment.
On-Device Controls and App Customization
- The top panel integrates Source button, Volume control knob, Bass control knob, Treble control knob, Play/pause button, Skip backward/forward control knob, and Power switch.
- Bass and treble can be adjusted directly on the speaker or through the Marshall Bluetooth app.
- Marshall recommends using the app for a more complete experience, but you can still handle playback and EQ control without it.
