KEF LSX II LT vs Q3 Meta Specs
Speaker Type
Edge: Tie
The KEF LSX II LT is an active wireless speaker with built-in amplification and streaming capabilities. You plug it in, and it handles all signal processing internally. This design simplifies your setup, as you do not need a separate receiver or amplifier to drive the drivers. In contrast, the Q3 Meta is a passive bookshelf speaker. It requires an external amplifier or receiver to function. This gives you the freedom to choose your own electronics and upgrade them over time. The LSX II LT offers convenience, while the Q3 Meta offers modular flexibility for a custom system.
Connectivity
Edge: KEF LSX II LT Wireless HiFi Grey
The LSX II LT provides extensive connectivity options for modern devices. It supports HDMI ARC and USB-C inputs, making it suitable for TV and desktop use. Wireless streaming is handled via Apple AirPlay 2, Google Chromecast, UPnP, and Bluetooth 5.0. It also connects directly to services like Spotify Connect and Tidal. The Q3 Meta has no built-in connectivity, as it is passive. It relies entirely on speaker wire connections to an external amp. If you want direct digital streaming or multiple input sources without extra gear, the LSX II LT is the clear choice for direct integration.
Dimensions
Edge: Tie
Size matters for placement. The LSX II LT measures 6.1 inches wide, 9.5 inches high, and 7.1 inches deep. It weighs 15 pounds. These compact dimensions allow it to fit on smaller shelves or desks. The Q3 Meta is significantly larger, measuring 8.3 inches wide, 14.1 inches high, and 12 inches deep. It weighs 18.1 pounds. The Q3 Meta is designed for medium-sized spaces where you want more room-filling sound. The LSX II LT is better for tighter spaces or desktop setups. You must measure your intended location carefully before deciding.
Audio Formats
Edge: KEF LSX II LT Wireless HiFi Grey
The LSX II LT supports high-resolution streaming up to 24bit/384kHz. It handles a wide range of formats including DSD, FLAC, WAV, AIFF, ALAC, AAC, WMA, MP3, M4A, LPCM, and Ogg Vorbis. This allows you to stream high-fidelity music from various sources without conversion. The Q3 Meta does not process digital formats itself. It reproduces whatever analog signal your external amplifier sends to it. The quality depends on your source and amp. If you want high-res decoding built into the speaker, the LSX II LT is superior.
Driver Technology
Edge: Tie
Both speakers use KEF’s Uni-Q driver array, placing the tweeter at the center of the main driver for a wide soundstage. The Q3 Meta adds Metamaterial Absorption Technology to reduce unwanted distortion, aiming for cleaner vocals and detail. The LSX II LT also features advanced engineering for its size, but specific driver sizes are not listed in the provided data. The Q3 Meta mentions a 6.5-inch driver for deeper bass.
