Short answer: the Edifier D12 is the sensible value choice, while the Marshall Stanmore III earns its premium with more power, deeper claimed bass and app control. At $179.99, the D12 gives you a real stereo layout, RCA and aux inputs, bass and treble knobs, plus a subwoofer output. Its 57Hz bass limit means it is better for close living-room listening than for genuinely deep low end.
The $388.99 Stanmore III uses an 80W three-way driver array and reaches a claimed 45Hz, so it has more scale for a larger room. It also adds an app, but it remains an AC-only speaker with no weather protection. Neither is a portable option.
Choose by room and source. The D12 has the more practical analog and subwoofer-routing package, while the Stanmore III is the better fit when stronger output and lower bass matter more than value.
Buy the Edifier D12 if you want affordable stereo sound, physical tone controls, RCA or aux sources, and the option to add a subwoofer later.
Buy the Marshall Stanmore III if you want the fuller, louder all-in-one speaker and will use its app-based controls in a permanent room setup.
