525 Watts for Effortless Headroom

The KH 350 uses the same powerful amplification architecture as the KH 310 II, with 300 W for the woofer, 160 W for the midrange and 125 W for the tweeter. This provides substantial headroom for larger listening environments, immersive production and demanding full-range monitoring applications.

Built for Nearfield, Midfield and Immersive Monitoring

The KH 350 is optimised for listening distances of 1.2–3.0 metres, while remaining suitable for approximately 1.0–9.0 metres depending on the room and application. Its vertical driver arrangement, controlled directivity, precise imaging and high output make it particularly well suited to stereo, multichannel and immersive monitoring, including Dolby Atmos environments.

A Larger Format Without Compromising Consistency

Measuring 545 × 280 × 363 mm and weighing 20 kg, the KH 350 uses a composite polycarbonate front, wooden sleeve and aluminium electronics panel. Its cabinet incorporates an 8¼-inch woofer, 3-inch magnetically shielded midrange and 1-inch tweeter with protective black metal grille, with two M8 side-panel mounting points for installation flexibility. Tight manufacturing tolerances help ensure consistent unit-to-unit matching across multi-monitor systems.

KH 310 II or KH 350?

The choice ultimately comes down to the monitoring environment and the amount of low-frequency authority and acoustic output required. The KH 310 II is the natural choice for critical nearfield monitoring where exceptional midrange transparency, tight bass, precise imaging and a compact sealed cabinet are priorities. The KH 350 moves into true midfield territory, offering greater low-frequency extension, higher output capability and controlled directivity for larger rooms and immersive systems.
