Most outdoor speakers look exactly like what they are: plastic boxes bolted to a wall or perched on a patio table. Earthquake Sound’s Granite-52 takes a different approach. The enclosures are molded from epoxy resin and finished with a granite texture that actually reads as stone from a few feet away. They’re sized to sit in garden beds, along pathways, or tucked beside patio edges.
The visual effect works best in natural settings where mulch, gravel, and greenery surround them. Up close, you can tell they’re not real rock, but at a glance they pass. That’s a harder trick than it sounds, and it’s the main reason these exist instead of another rectangular outdoor box. Most buyers won’t think twice about the enclosure material until they realize nobody’s asked “what’s that?” about the speaker sitting next to the flower bed.
Price: $179.99
Where to Buy: Amazon
Right now, Amazon has the Granite-52 pair at $179.99, down from a 30-day average of $287.84. That’s roughly 37% off and well below Earthquake Sound’s own $379.99 direct price. It’s a steep enough cut to notice on a product that doesn’t cycle through frequent sales, and for outdoor audio built to vanish into your yard, the gap between retail and this deal is wide enough to matter.
What’s inside the enclosure
Each speaker holds a 5.25-inch woofer and a small 0.5-inch tweeter stacked together in one unit. The rubber surrounds and poly cones are built to handle heat, cold, and everything between, which is where cheaper materials tend to fall apart. Stacking both drivers together keeps the speaker compact while letting each one handle its own range of sound.
Every Granite-52 unit is fully sealed. No ports, no openings, no ventilation slots. That’s on purpose, not a shortcut. Speakers with ports can push deeper bass, but those same openings let water, bugs, and dirt creep inside over time. For something that lives outside through every season, a sealed cabinet trades a little bass depth for a much longer life. The resin shell gets UV protection and a weather-resistant coat built to handle years of sun, rain, and freezing temperatures. It’s the kind of trade-off that pays for itself three winters from now, when cheaper outdoor speakers have already rusted out from the inside.
How the price compares everywhere else
The price gap between Amazon and everyone else tells its own story. Over 90 days, these speakers have averaged $288.61. The 180-day average sits at $242.58, and specialty retailer Sound Approach lists them around $405, nearly double the current Amazon price. At $179.99, you’re paying less than half of what Earthquake Sound charges on its own website, which makes this the cheapest entry point for the Granite-52 in recent memory.
For context, Klipsch sells its AWR-650-SM outdoor rock speaker for $199.99, down from $330, and Victrola’s solar-powered rock speaker runs $119.99. The Granite-52 slots between both on price while offering a sealed, passive design that skips the compromises of built-in solar panels or wireless electronics. Against the closest competition, the deal math still holds up.
Passive wired setup, no wireless anything
One thing worth knowing up front: these are passive speakers. There’s no built-in amplification, no Bluetooth radio, no Wi-Fi streaming. You’ll run speaker wire from a receiver or outdoor amp to each unit. That’s normal for permanent outdoor audio, but it’s a different setup than pulling a Bluetooth speaker off the shelf.
The wiring isn’t hard, though you’ll want to plan your cable route before placing speakers in the garden. Most outdoor amp setups handle it cleanly with buried or hidden wire runs. The payoff for going wired is simple. There are no batteries to charge, no firmware updates to install, and no wireless pairing failures to troubleshoot on a Saturday afternoon when you want music on the patio. The signal path stays simple and reliable. For anyone setting up permanent backyard audio, that simplicity beats the wireless convenience that often comes with wireless headaches.
Weather rating and where they fit
Earthquake Sound rates the Granite-52 for rain, humidity, UV exposure, and seasonal temperature swings. They aren’t marketed as submersible or designed for standing water, so keep them above grade in spots where drainage works.
Where these speakers land visually depends entirely on the space around them. In garden beds with bark mulch, river rock, or natural stone borders, the granite finish blends convincingly. A casual visitor probably won’t spot them at all, which is the whole point. Patios with clean modern lines and smooth concrete surfaces are a tougher fit. The organic rock shape reads as out of place when everything else is minimal and geometric. Knowing your yard’s visual language before buying saves a return.

The bottom line on this deal
The deal is live on Amazon now with no listed expiration. At this price, the Granite-52 pair sits well below its historical average and far under what any other retailer currently charges. For outdoor audio that’s built to weather years of exposure without looking like consumer electronics, the value math works. Stock and pricing on deals like this tend to shift without warning, so it’s worth checking sooner rather than bookmarking for later.
