NEW DELHI: Marshall lists the Acton IV at Rs 31,999 and the Stanmore IV at Rs 41,999 on its India website. Both home speakers come in Black and Cream, with no colour premium in the four listings checked. These are the displayed MRPs, so the table compares the same price basis across the range.
| Model | Colour | India MRP |
|---|---|---|
| Acton IV | Black | Rs 31,999 |
| Acton IV | Cream | Rs 31,999 |
| Stanmore IV | Black | Rs 41,999 |
| Stanmore IV | Cream | Rs 41,999 |
Price as of 2 November 2026, 01:10 IST. The table covers every colour listed for these two models on Marshall's India speaker catalogue. A listed MRP is a reference price, rather than a promise about the amount a particular checkout or dealer will charge.
The cabinet makes the clearest distinction
Acton IV measures 260 x 171 x 150mm and weighs 2.65kg. Stanmore IV is larger at 350 x 203 x 185mm and 3.99kg. For an Indian home with a crowded study shelf or a narrow sideboard, those measurements are more useful than treating the higher price as an automatic upgrade in every situation.
The smaller model has a 4-inch woofer, while Stanmore IV uses a 5-inch woofer. Both have two 0.75-inch tweeters with waveguides. Marshall specifies a 60W Class D amplifier for the woofer and separate 25W Class D amplifiers for each tweeter on both product pages.
That shared amplifier specification is an instructive detail. The price gap does not buy a different amplifier wattage on the published sheets. Cabinet size, the larger woofer and the acoustic design remain part of the comparison. Wattage alone would conceal the most visible differences between these particular speakers.
Auracast needs a source
Both models list Bluetooth 5.3 with Auracast and Bluetooth multipoint. Marshall describes the speakers as Auracast receivers. They can join a broadcast from a compatible device, rather than creating a complete streaming network simply because another speaker is nearby.
The company's Heddon streaming hub is one possible broadcaster. Marshall says a long press on the speaker's M-button joins its broadcast once Heddon is in setup mode. Compatible phones can also supply broadcasts, with the Marshall app's Listen to Broadcast function or the phone's supported operating-system controls handling the connection.
This matters when planning music between a living room and a dining space. An Auracast badge establishes a connection capability; the household still needs a suitable broadcasting source. Check that part of the setup before treating a second speaker as the only extra component required.
Controls stay on the speaker
Acton IV and Stanmore IV both retain separate bass, treble and volume controls, alongside a power switch, media control, source button and customisable M-button. The Marshall app adds EQ settings and placement compensation. The company also describes Dynamic Loudness as adjusting tonal balance as listening volume changes.
For a shared household, the physical controls have a practical consequence: someone can adjust the sound without first finding the phone running the app. Placement compensation addresses a different task, tailoring the setup to where the speaker stands. Neither feature provides a measured listening result for a particular room.
Marshall describes revised tweeters, waveguides and bass ports on these fourth-generation models. Those are the company's design claims, rather than findings from a listening test here. Readers comparing the earlier generation can also see our Watch and audio price guide.
Read the connection details carefully
The Stanmore IV specification explicitly lists AUX 3.5mm and RCA inputs. Acton IV's feature text and FAQ describe RCA, but its wired-connectivity specification lists only AUX 3.5mm. That inconsistency makes the Acton socket layout something to confirm against the unit or its manual before arranging an analogue source around it.
These are mains-powered home speakers, with a mains lead listed in each box.
