Description
Sonus is Latin for sound, which is a fitting name for a can built to take sound out of the equation. The Energetic Armament Sonus is a full-auto rated 9mm suppressor that tips the scale at just 9.8 ounces with the direct thread mount installed, and it gets there without giving up toughness. The whole thing is machined from US-made, DFAR certified 17-4 stainless steel heat treated to the H900 condition, which lets Energetic run thinner walls than most of the competition. Thinner walls mean more internal volume in the same footprint, and more volume means better sound attenuation. They also shed heat faster, pulling energy out of the muzzle gases before it ever reaches your ears.
One Sonus, a Whole Safe Full of Hosts
At 6.6 inches long and 1.5 inches in diameter, the Sonus stays trim enough for pistol duty while still handling a lot more than 9mm NATO. It carries ratings for .380 ACP, 300 Blackout in both supersonic and subsonic flavors, .38 Special and .357 Magnum, subsonic 8.6 Blackout, and 350 Legend with a 10 inch or longer barrel. There are no barrel length restrictions as long as you keep it under 1,000 degrees. That range covers everything from a nightstand pistol to a lever gun to a suppressed bolt action.
Mounting Options and That Wiped End Cap
The rear of the Sonus uses the industry standard 1.375×24 HUB pattern, so it works with Bravo-style quick disconnect mounts, 3-lug adapters for subguns, and piston boosters for tilting barrel pistols. A removable 1/2×28 direct thread adapter comes in the box, so you can mount up right away. Up front, the removable end cap accepts a high-temperature silicone wipe that seals around the exiting bullet, squeezing extra quiet out of subsonic loads when you want the softest report possible.
Built to Stay in the Family
The MetOx burnt bronze finish gives each Sonus a one of a kind look while adding wear and corrosion resistance, and Energetic Armament backs the whole package with a lifetime guarantee. The patented Serial ID Ring keeps the serial number on a separate ring rather than the core, which makes servicing down the road a much simpler affair.

Frequently Asked Questions
Will the Sonus 9mm suppressor work on my pistol with a tilting barrel?
Yes, with the right hardware. The Sonus uses the industry standard 1.375×24 HUB pattern, so it accepts any HUB compatible piston booster assembly for reliable cycling on Browning-style tilting barrel pistols. The booster is sold separately, but the ecosystem of compatible options is huge.
What is the wipe in the end cap for, and do I have to use it?
The removable end cap holds a high-temperature silicone wipe that seals around the bullet as it exits, trapping gas for noticeably quieter performance with subsonic ammo. It is completely optional, so you can run the can without it for supersonic loads or high volume shooting. Wipes are a consumable item and get replaced as they wear.
Can I shoot anything besides 9mm through the Energetic Armament Sonus?
Absolutely. Beyond full-auto rated 9mm NATO, the Sonus handles .380 ACP, 300 Blackout in both subsonic and supersonic, .38 Special, .357 Magnum, subsonic 8.6 Blackout, and 350 Legend on barrels 10 inches or longer. That flexibility makes it a solid pick for lever guns and bolt actions in addition to pistols and PCCs.
What is the Serial ID Ring on the Sonus?
Energetic Armament puts the serial number on a patented separate ring instead of engraving it on the suppressor core. If the core ever needs service or replacement, it can be swapped while the serialized ring stays put, which makes the process much faster and simpler. It pairs nicely with the lifetime guarantee that backs every Sonus.
