The ultimate reference standard for low frequency excellence from a sealed cabinet subwoofer design.

Born from three decades of SVS design expertise, the pinnacle of subwoofer performance is here with the SB17-Ultra R|Evolution. Reimagined dual mono-block STA-2800 amplifier technology, first ever 17-in driver with dual 8-in voice coils, and the most powerful DSP ever used in a consumer subwoofer married to advanced power management and auto EQ room calibration. The benchmark for reference subwoofer experiences has arrived.

Breathtaking low frequencies with unerring accuracy, musicality, and stop-on-a-dime control. The deep, chest-thumping slam of cinematic soundtracks and the delicate nuance of musical bass always rendered truthfully.

Whether heard or felt, low frequencies are handled effortlessly without sacrificing sonic fidelity and refinement. With extension to 15 Hz, far below the threshold of human hearing SB17-Ultra R|Evolution brings sound to life with convincing, visceral, and jaw-dropping impact.

High-Excursion 17-Ultra R|Evolution Driver

  • 17-inch glass fiber composite cone with 55 lb toroidal ferrite magnet motor assembly render massive low frequency output down to 15Hz with pinpoint accuracy and control.

8-inch Dual Voice Coil

  • Dual voice coil design ensures stable and consistent transfer of motor electro-magnetic energy to the 17-inch cone to maintain precise driver control with maximum efficiency.

Dual Mono Amplifier

  • Each of the two Class-D mono-block amplifiers with MOSFET output stages drives one of the dual voice coils to double the amount of current being fed to the driver achieving effortless output with lower continuous current demand from a home’s AC circuit.

Switch Mode Power Supply

  • Time aligns the AC voltage to the AC current while filtering and stabilizing incoming voltage to optimize signal quality and audio performance.

295 MHz Analog Devices DSP

  • The most advanced processor ever used in a consumer subwoofer optimizes every aspect of subwoofer output and usability to maintain flawless performance and intuitive control.

SVS Subwoofer Control Smartphone App

All 3 dogs, 3 different sizes and ages love it! Can’t go wrong!
Size: Medium, Style: Bristle Bone
Great! Super great! When you HAVE TO GET THEM OUT OF YOUR HAIR! This toy is durable even without the beef flavored insert! I have a Border Collie who has too much energy and an Aussie who can’t sit still and a small stray who is constantly figuring out a way to steal these from the other two! Safe, effective and actually cleans their teeth! This might well be my first Amazon review because this toy deserves it!

Bully approved
If he wants something to gnaw on he will sit with it but he doesn't really play with it. Which is probably the point. It's lasted. The ends are the most chewed. Overall great for a chewer!

Surprisingly Durable
Color: Green
Our dog is an aggressive chewer. She has destroyed other toys meant for "aggressive chewers" in less that 6 hours. This toy has lasted 17 days and it's still going. It does have areas were the seam has given way and a very small amount of stuffing has come out. She has "killed" the squeaker. But the toy is still usable. We just played Tug of War this morning. It will not last forever. It is showing it's "age". But the durability is there. I am ordering more.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.
