The Bronze On-Wall 6G is a highly flexible addition to the Bronze Series. Not only does the super-slim profile allow it to be a perfect rear and side channel AV speaker, but it also means that it is perfect for wall-mountable front LCR (left-centre-right) applications – making it an ideal home cinema speaker. Featuring the latest C-CAM 1-inch gold dome tweeter featuring the UD waveguide, and highly dynamic 6.5-inch bass-mid driver; benefiting from the latest C-CAM cone technology and powerful motor system. The Bronze On-Wall 7G is a highly versatile, décor friendly alternative, delivery, detailed high-fidelity surround sound in abundance.
A starting point for acoustic excellence.
The Bronze On-Wall 7G is a slim, décor-friendly speaker that brings high-fidelity performance to wall-mounted stereo and surround sound systems. Ideal for front LCR and rear or side channel AV use, its compact profile offers flexible placement without compromising on sound.
Featuring a 1-inch C-CAM gold dome tweeter with UD waveguide and a dynamic 6-inch C-CAM bass-mid driver, it delivers tight bass, crisp highs and immersive detail. A new crossover design and HiVe II port technology ensure smooth, punchy performance across the frequency range.
Ideal for versatile placement, the Bronze On-Wall 7G is an elegant choice for audiophiles and movie lovers alike.
A captivating class leader.
Bronze Series 7G exudes all the qualities you’d expect in terms of craftsmanship and sonic excellence that many have followed, yet very few have bettered.
Bronze has always led and is the entryway into achieving an enhanced listening experience.
A Jewel in the Crown.
One of the more distinct design features on the Bronze Series 7G is the tweeter. The C-CAM gold dome, protected by an aluminium-etched hexagonal grille design, blends seamlessly into the hexagonal waveguide, allowing the high frequencies to reach the listener with the minimum of obstruction to deliver detailed, clear and pristine high fidelity.
Compact, controlled and crystal clear.
The latest incarnation of the Gold Dome tweeter, within Bronze Series 7G, is not only thinner, lighter and more rigid than the previous 6th generation, but its carefully formed profiled dome now benefits from the UD (Uniform Dispersion) Waveguide II. This improves time alignment and allows a lower frequency to crossover for wider directivity.
Delivering life-like clarity.
The Bronze Series 7G utilises a bass-mid driver design that features large magnets and a voice coil, giving this Bronze range much higher power handling and high sensitivity and thus delivering far greater control and more accurate time responses.
What this means is that movie soundtracks, from the quietest to the most dynamic passages or delicate strings to powerful bombastic music passages, are delivered with total realism and neutrality.
Crossover Design – the purest of signals.
The crossovers for Bronze Series 7G have been optimised over many hundreds of hours of listening, each component having been carefully selected by the R&D team. Each component has gone through rigorous measurement testing to improve the overall ‘system design’, and with high-quality capacitors and transistors used – at this price point – the Bronze Series 7G provides detailed and precise sound delivery across all audible sound frequencies for an engaging listen.
Powerful Bronze bass, to move you.
Below the smooth metallic finish of the Bronze Series 7G C-CAM drivers lies a powerful motor system – designed for agility, accuracy and impact.
We’ve introduced a new progressive spider design to ensure smoother, more controlled driver movement, improving excursion linearity. The voice coils on this generation of Bronze are much larger than the previous, now 28.5mm compared to 25mm. The result? Far more bass extension and greater power handling for controlled, punchy, articulate bass.

Unleash Studio-Quality Sound
Meet the WiiM Amp Ultra – our most advanced streaming amplifier yet. Built for music lovers, home theater buffs, and smart home fans, it delivers stunning 100W per channel (8Ω) with ultra-low distortion, pushing high-fidelity audio to every corner of your space. Whether it’s vinyl, Spotify, or cinematic surround sound—you’ll hear it like never before.
Beautiful Inside and Out
Designed to stand out and fit in, the Amp Ultra features a sleek unibody aluminum chassis and a vibrant 3.5″ glass-covered touchscreen. Easily control playback, switch sources, view album art, and more—all at your fingertips.
Flagship Components, Flawless Fidelity
Under the hood, the Amp Ultra is powered by top-tier components:
ESS ES9039Q2M SABRE DAC
Dual TI TPA3255 Class-D amplifiers
Six TI OPA1612 op-amps
Combined with Post Filter Feedback (PFFB) technology, it delivers clean, detailed sound with consistent performance across all speaker loads—perfect for bookshelf, floor-standing, or in-wall speakers.
Post Filter Feedback Technology
At the core of the WiiM Amp Ultra’s superior sound is its advanced Post-Filter Feedback (PFFB) technology, a cutting-edge refinement system that minimizes distortion, enhances clarity, and ensures consistent sound quality across different speaker loads. Unlike traditional amplifiers that suffer from load-dependent performance variations, PFFB dynamically compensates for these inconsistencies, delivering a more accurate, balanced, and natural sound signature. The result? A wider soundstage, richer details, and an immersive listening experience that faithfully reproduces every note with precision and depth.
