Outdoor audio has moved well beyond a pair of weather-resistant speakers screwed beneath the eaves. Premium systems can now cover large properties, disappear into landscaping and deliver enough bass and output for everything from background music to an outdoor theater; my neighbours would rather angrily agree with that assessment.
KEF is finally entering that market in a serious way.
The new KEF Outdoor Collection includes landscape satellites, bollard speakers, dedicated subwoofers, full-range three-way bollards and four KASA Network DSP amplifiers. It also marks the first time KEF has engineered versions of its Uni-Q driver array specifically for outdoor loudspeakers.
KEF already offered the Ventura 5 and Ventura 6 surface-mount speakers, which remain part of the collection. The company describes those as existing “proven performers,” so the real news is everything being added around them.

What’s New?
The range is considerably larger than it first appears.
Type Models Landscape satellites SR4F, SR4Q, SR6Q Bollard speakers BH6Q, BH8Q Bollard subwoofers BL8Sb, BL8b, BL12b Three-way bollard speakers BQ9, BQ11 Network DSP amplifiers KASA 2-250M, KASA 4-250M, KASA 8-150M, KASA 8-250M Packaged systems Landscape P4F, P4Q, P6Q Existing surface-mount models Ventura 5, Ventura 6
There are a couple of potential traps in that list.
The SR4F and BL8Sb are not individually identified in the main product rundown in KEF’s initial documentation for the media. Both appear in the documentation for the $2,000 Landscape P4F package, which combines four SR4F satellites with one BL8Sb subwoofer.
The SR4F is also not a Uni-Q speaker. It uses a conventional 4-inch full-range driver and represents the simpler entry point into the new range.
Uni-Q Heads Into the Garden
The SR4Q and SR6Q landscape satellites use 4.5-inch and 6.5-inch Uni-Q arrays, while the BH6Q and BH8Q bollards move up to 6.5-inch and 8-inch versions.
That concentric architecture makes considerable sense outdoors. Positioning the tweeter at the acoustic center of the midrange cone creates a point-source arrangement designed to maintain more consistent dispersion across a broad listening area rather than favoring one narrow seat.
The four models differ substantially in output and coverage.
Model Driver Response ±6 dB Max SPL Nominal Coverage SR4Q 4.5-inch Uni-Q 108 Hz–20 kHz 106 dB 90° SR6Q 6.5-inch Uni-Q 101 Hz–20 kHz 109 dB 80° BH6Q 6.5-inch Uni-Q 81 Hz–20 kHz 109 dB 130° BH8Q 8-inch Uni-Q 75 Hz–20 kHz 112 dB 100°
The SR4Q and SR6Q require KEF Network DSP amplification, as do the BH6Q and BH8Q. KEF specifies 150 watts for four SR4Q speakers wired in parallel, 240 watts for four SR6Q speakers, and 240 watts for either BH bollard.
The BQ9 and BQ11 Are the Interesting Ones
The BQ9 and BQ11 are not merely taller versions of KEF’s other bollards.
Each is a genuine three-way loudspeaker combining a Uni-Q array with a dedicated long-throw woofer and an internal passive crossover. The BQ9 uses a 6.5-inch Uni-Q with an 8-inch bass driver; the larger BQ11 mates an 8-inch Uni-Q to a 12-inch woofer.
The BQ9 reaches 35 Hz ±6 dB and 109 dB maximum SPL, while the BQ11 extends to 30 Hz and 112 dB. KEF recommends 240 and 400 watts respectively.
There is another important difference. Unlike the BH and Q-series landscape models, the BQ9 and BQ11 use passive crossovers and do not require a KASA amplifier. KEF specifically says they can be used with the owner’s preferred amplification.
That makes the BQ models particularly intriguing for high-end stereo and outdoor theater installations where the owner already has suitable amplification.
Bass Without Burying a Refrigerator
The new BL range provides two main KASA-optimized outdoor subwoofers.
The BL8b uses an 8-inch long-throw driver, reaches 27 Hz ±6 dB and delivers a claimed 109 dB maximum SPL. The BL12b uses a 12-inch driver, extends to 24 Hz and increases maximum output to 115 dB. Both radiate through 360 degrees.
KEF rates their nominal coverage areas at 120 and 200 square meters respectively and recommends 150 watts for the BL8b and 400 watts for the BL12b.
The P4F package uses the separate BL8Sb, an 8-inch dual-coil model with a 28 Hz–133 Hz ±6 dB response and 101 dB maximum SPL.
Three Ready-Made Landscape Systems
KEF is also simplifying the process with three 4.1 packages.
- The Landscape P4F ($2,000) includes four SR4F full-range satellites and the BL8Sb subwoofer. Unlike the other two systems, amplification is not included.
- The Landscape P4Q ($5,000) combines four SR4Q Uni-Q satellites, one BL8b subwoofer and the KASA 2-250M.
- The Landscape P6Q ($8,000) moves to four SR6Q satellites, the BL12b and a KASA 4-250M.
Both Uni-Q packages can be expanded to 8.2 or larger installations rather than forcing the buyer to replace the original system as the property grows.
KASA Is More Than an Outdoor Amplifier
The four new KASA models may have broader implications for KEF’s custom-install business.
The KASA 2-250M, 4-250M, 8-150M and 8-250M combine Class D amplification using GaN FET output stages with AKM Velvet Sound ADC/DAC conversion and KEF’s Music Integrity Engine DSP. A browser-based interface handles setup, source routing, multi-zone configuration and independent volume control without requiring a dedicated application.
KEF’s MIE profiles contain model-specific processing for compatible architectural speakers, allowing the installer to select the connected KEF model rather than creating its DSP configuration from scratch.
Analog RCA, optical and coaxial inputs are provided, along with buffered pass-through outputs. There is no indication in the supplied specifications of integrated Spotify, Qobuz, AirPlay, Google Cast or similar music services, so “Network DSP Amplifier” should not be confused with a network streamer.
The detailed power specifications are also worth reading rather than stopping at the model numbers.
Model Channels 4Ω Single Channel All Channels Driven at 4Ω MSRP KASA 2-250M 2 250 W 250 W/ch $1,600 KASA 4-250M 4 250 W 250 W/ch $3,200 KASA 8-150M 8 150 W 135 W/ch $3,300 KASA 8-250M 8 250 W 135 W/ch $4,000
That last column requires some attention. KEF markets the KASA 8-250M as an 8-channel 250-watt model, but its detailed specifications rate it at 135 watts per channel into 4 ohms with all eight channels operating simultaneously. The 250-watt figure applies to the single-channel test condition.
Nothing nefarious there, but eight times 250 watts is not what comes out of the box when every channel is working.
Designed for Actual Weather
KEF gives the landscape satellites and BH bollards an IP66 rating, while the BL subwoofers and BQ three-way models carry IPX5 certification.
The new speakers are UV resistant, specified to operate from -13°F to 158°F and have undergone more than 500 hours of salt-spray testing.
Ground stakes and hardscape mounts cover most installations, with additional surface, deck and mounting-column options depending on the model.
What Does KEF Compete With?
The premium landscape category is not empty, and two main competitors we’ve heard stand out.
Theory Audio Design ic6-Bollard and iws12-Bollard
Theory has less product variety than KEF’s new range, but considerably more raw output from its two-model landscape platform. If someone wants the backyard to become an outdoor nightclub, that matters.
The ic6-Bollard ($2,795), which earned eCoustics Editors Choice in 2025, uses a 6.5-inch carbon-fiber driver with a 1.4-inch compression driver and provides true 360-degree horizontal coverage. Theory specifies 68 Hz-23 kHz at -6 dB, 112 dB maximum SPL using its AES rating and 118 dB peak output.
Theory’s iws12-Bollard ($3,560) high-output subwoofer uses a 12-inch driver with a 4-inch voice-coil that reaches down to 29.5 Hz at -3 dB and is rated for 124 dB maximum SPL. Both require Theory DSP processing and amplification.
Focal Littora OD 4.1
Focal’s Littora OD range combines a number of options for outdoor applications including speakers that look like rocks, along satellite/subwoofer speaker bundles. Amplification isn’t included, but Focal’s sister company Naim Audio provides a number of options along with very nice app to control music zones which can be used both inside and outside the house.

The Bottom Line
KEF has sold weather-resistant speakers before. What it did not have was a complete outdoor ecosystem capable of scaling from a modest 4.1 garden setup to large distributed installations and full-range stereo or theater systems.
The most important additions are not necessarily the obvious ones. The BQ9 and BQ11 bring legitimate three-way architecture into the landscape, while KASA gives KEF control over amplification, DSP and installation instead of relying on somebody else’s electronics.
We will need to hear the new range before deciding whether KEF has successfully transported its sonic DNA from the listening room to the backyard. On paper, however, this is a much bigger move than another pair of speakers designed to survive the rain.
