I’m not telling you anything you don’t already know here, but the way most people shop for audio products barely resembles the way hi-fi enthusiasts and audiophiles shop for audio products. Imagine you’re in the market for an outdoor audio system centered on passive speakers intended to be driven by an amp. You and I might research the category, do comparisons based on specifications, try to read some reviews, factor in any brand loyalties we might have, and plunk down our credit cards after some careful deliberation. Most people purchasing KEF’s Ventura 6 outdoor speaker (US$599.99, CA$749.99, £459, €599 per pair), on the other hand, probably asked their custom integrator for an outdoor speaker system, and it just so happened that their integrator was a KEF dealer.

That’s not casting aspersions on anyone or anything, mind you. There is zero judgment in the above paragraph. It’s simply a recognition of reality. But for folks like us, what might lead one to choose the Ventura 6 over all the other passive outdoor speakers on the market?

Frankly, KEF doesn’t give us a lot to work with in this regard, mostly for the reason stated above. But there are a few key characteristics worth considering. The Ventura 6 features a 1″ aluminum dome tweeter and 6.5″ polypropylene woofer in an ABS cabinet with your choice of a black or white UV-resistant finish. It’s IP65-rated and designed to stand up to salt spray. Sensitivity is specified as 90dB (on the higher end for this category), nominal impedance is 6 ohms, and recommended amplifier power is 10 to 125 watts. KEF also specifies the frequency response as 54Hz to 20kHz, although if you’re new to outdoor audio, it’s important to note that you’re only going to get that sort of bass extension with a lot of boundary reinforcement.

Setting up and dialing in the Ventura 6 speakers

The Ventura 6 is sold in pairs, and each box comes with two mounting brackets and ratcheting screw-in caps that allow you to rotate the cabinets up to 180 degrees and lock them in place with a twist. If you’re installing them horizontally, that rotation is up/down, and of course if you’re installing them vertically, the rotation is left/right. Either way, you can tug the KEF logo out and rotate it to match your installation orientation quite easily. Let it go and it snaps right back into place.

Other than that, installation considerations are so site-specific that it’s hard to make much in the way of useful generalizations. For my evaluation, I installed the Ventura 6 pair under my corrugated galvanized steel patio cover by screwing the mounting brackets into the fascia boards of my main roof. Initially, I had them installed horizontally, since I didn’t think I had room for a vertical installation, but I later found a way to make it work and reinstalled the speakers for a fresh listen.

The amp for this install was a Fosi Audio BT20A Bluetooth stereo amplifier with the default 24V/4.5A power supply, giving me a healthy 100Wpc of output into 4 ohms, which turned out to be plenty of power for this setup. For speaker cables, I relied on some 3m (9.8′), 14AWG, pre-terminated wires from Ucinnovate, which cost me like $26 and were among the last purchases I ever made from Amazon before I canceled my Prime subscription once and for all.

How does the Ventura 6 perform?

I’ve got two words for you when it comes to getting the best sound from the Ventura 6: yacht and rock. Chalk it up to the influence of the summer weather, blame my advancing age, or write it off as mere happenstance, but the fact that the first thing I fed the Ventura 6 speakers was my go-to Yacht Rock playlist on Apple Music put the speakers in the best light possible, because they really do excel with this sort of lounging-by-the-pool music.

First up was “What a Fool Believes (2016 Remastered)” from Doobie Brothers’ Minute by Minute (24-bit/192kHz ALAC, Rhino / Apple Music), which bounced right out of the Ventura 6 speakers and practically bathed my patio and small backyard with detailed, sparkling sound that had exactly the right amount of bass and a bit more high end than I’m used to hearing, but not in a bad way. The vocals were a bit forward but never strident. Percussion had a really neat shimmer and lots of texture, but never got eardrum-stabby, as this track can sound on overly bright speakers.

“Summer Breeze” by Seals & Croft (16/44.1 ALAC, Warner Records / Apple Music) also boasted excellent stereo separation, even when I was sitting on my rocking swing a little too close to the wall on which the speakers were installed. I’d say the triangle formed by the speakers and my head was far more of a squat isosceles than a proper equilateral, and yet there was a really nice soundstage and good channel delineation, albeit coming from behind me. The guitars and percussion benefited from oodles of texture, and vocals sounded really good, if not 100 percent accurate.

Deviating from my Yacht Rock playlist, I loaded up a rather recent obsession: “Keep That Funk Alive (feat. Bootsy Collins)” from Lettuce’s excellent 2022 album Unify (24/48 ALAC, Round Hill Records / Apple Music). Bass extension here was surprisingly solid, and the mix overall benefited from the same sparkly high-end that elevated the textures and detail of previous selections. Vocals were a little hollow, but only a little. The mix also sounded really solid and cohesive, even when I maxed the output of my little Fosi amp.

One cut that didn’t hold up quite so well in the face of full volume was “Rebirth of Slick (Cool Like Dat)” from Digable Planets’ Reachin’ (A New Refutation of Time and Space) (16/44.1 ALAC, Pendulum Records / Apple Music). Mind you, for the most part the mix sounded amazing. The Ren and Stimpy–esque bass line held its composure gorgeously. The rhythmic snaps leaped right out of the cabinets into my yard. But when I cranked the volume past 80 percent, the boom-bap drum beats started to sound a little rough, and I could hear some cabinet resonances.

“The Revolution Will Not Be Televised” from Gil Scott-Heron’s Pieces of a Man (16/44.1 ALAC, Ace Records / Apple Music) also came up a little short for a couple of reasons. Let’s start with the good, though, since there was a lot to like about the Ventura 6s’ delivery of the song. Detail was every bit as good as any other reference track I threw at the system, and the speakers managed that without sounding a bit harsh or bright. Still, Scott-Heron’s voice sounded a bit weak compared to the rest of the mix, and it exhibited some of the hollowness I heard in “Keep That Funk Alive (feat. Bootsy Collins).”

As I mentioned above, I originally installed the speakers horizontally and tilted them down a bit, but toward the end of my evaluation, I re-mounted the brackets in a vertical orientation and toed them in a little. And the differences were not quite what I would have predicted. I knew the dispersion would be different, since this is a two-way design and not of the coaxial sort we’re accustomed to with KEF speakers. So in a horizontal installation, the dispersion is smoother in the up-down axis, whereas in a vertical installation the dispersion is smoother in the left-right axis.

But once you factor in the rotation of the speakers, the unintended consequence of this was that a horizontal installation gave me more freedom to move out into the yard and deeper into the patio, toward the house, without noticing any significant changes in tonality, whereas the vertical orientation allowed me to piddle around on the patio, working at my standing planting station and moving over to a higher work table, with more consistent sound coverage. So deciding which orientation is better for any given installation really boils down to how high the speakers are installed, how much they’re rotated up/down or left/right, and how you use the space.

What other similar outdoor speakers should you consider?

A lot of outdoor speakers from manufacturers you’ve heard of deliver comparable specs at comparable prices. A few you might consider are the JBL Stage XD-6 ($600/pair), the Definitive Technology AW-550 ($599/pair), the Elac Muro OD-M61 ($599/pair), and the one-cabinet stereo Paradigm Stylus 470-SM ($549.99/each).

Most of them lack the on-paper bass extension of the KEF Ventura 6, but as I said above, how much actual usable bass you’re going to get really depends on where you install the things. Getting good bass outdoors isn’t easy, and if you want to feel that rumbly in your tumbly, you might be better off adding a buried outdoor sub.

The best bass I’ve heard from an outdoor speaker with a similar form factor to the Ventura 6 is the Dayton Audio IO8XTB ($294.99/each), which reaches down to a shocking 38Hz thanks to its 8″ woofer and large passive radiator. It also has both 8-ohm and 70V taps, so you can use it in a stereo setup similar to the Ventura 6 or string a bunch together like monophonic Christmas lights.

TL;DR: Should you buy a pair of KEF Ventura 6 outdoor speakers?

Whether or not the KEF Ventura 6 is the right outdoor speaker for you honestly hinges on so many variables that it’s hard to give meaningful advice on this front. There’s nothing about the speaker that makes it distinctively KEF—and I’m not sure the company’s beloved UniQ driver could really successfully be adapted for outdoor use, although maybe I’m wrong about that.

What it really ultimately boils down to, since with most outdoor speakers form follows function, and as such most of these offerings are remarkably similar, is whether the voicing works for your tastes. And I have to say, I like the voicing of this one a lot. The enhanced detail without adding harshness is something I probably wouldn’t dig in a dedicated stereo setup. But outside, it just works, and it allows the music to work its magic on you even if you’re baking in the sun or getting baked after sundown.

All things considered, I think the Ventura 6 is a good value, and I’m a little sad to see this pair go back to the manufacturer. I think I might be replacing them sooner rather than later.
