KEF vs Polk Audio Spec Comparison
Speaker Type
Edge: Tie
The KEF LSX II is a powered active speaker, meaning it has built-in amplification and requires no external receiver to function. This makes it a self-contained unit for desktops or TV consoles. In contrast, the Polk Audio Monitor XT60 is a passive tower speaker. It requires an external amplifier or receiver to drive its drivers. The active design of the KEF simplifies setup for casual listeners, while the passive Polk offers flexibility for those building a larger, component-based home theater system with separate amplification sources.
Connectivity

Connectivity options differ significantly between these two systems. The KEF LSX II includes HDMI ARC, USB-C, Bluetooth, Apple AirPlay 2, and Google Chromecast. This allows direct digital connection to a TV for audio return and wireless streaming from various devices. The Polk Audio Monitor XT60, being a passive speaker, lacks any built-in connectivity ports. It connects via binding posts to an external receiver. If you need direct TV integration or wireless streaming without extra gear, the KEF provides more versatile native connections for immediate use.
Audio Format
Edge: Polk Audio Monitor XT60 Tower Speaker
Immersive audio support is a key consideration for home theater enthusiasts. The Polk Audio Monitor XT60 is explicitly compatible with Dolby Atmos, DTS:X, and Auro 3D. These formats enable height channels and object-based audio for a three-dimensional sound experience. The KEF LSX II data does not list specific immersive audio format compatibility. It focuses on high-fidelity stereo reproduction via its Uni-Q driver array. If you plan to watch movies with surround sound formats, the Polk is the only option here that supports these specific technologies.
Woofer Size

Driver configuration impacts bass response and soundstage. The Polk Audio Monitor XT60 features a 6.5-inch woofer and two 6.5-inch passive radiators. This larger driver size, combined with passive radiators, is designed to deliver smooth mid-range and deeper bass in a floorstanding enclosure. The KEF LSX II uses a 11th-generation Uni-Q driver array with a tweeter mounted inside the woofer cone. While compact, this design aims for a wide sweet spot. The Polk offers physically larger drivers for potentially greater low-frequency output in a dedicated theater setting.
Dimensions

Physical footprint determines where you can place these speakers. The KEF LSX II is a compact bookshelf speaker measuring 9.5 inches wide, 6.1 inches high, and 7.1 inches deep. It weighs 15.6 pounds. The Polk Audio Monitor XT60 is a large tower speaker standing 36 inches high, 10 inches wide, and 7 inches deep, weighing 20 pounds. The KEF fits easily on desks or small shelves. The Polk requires floor space and a dedicated corner or wall placement. Your available room size and furniture will dictate which form factor is practical for your setup.
