I have had SV subwoofers since 2004, starting with the PB2-Plus line. Everyone knows their subs hit hard and deep for home theater content and that’s why I went with them originally.
Recently I upgraded my two channel space and got a pair of Wilson Audio MAXX series 3 loudspeakers, paired with a D’agastino Progression pre-amp and stereo amplifier. My vocabulary cant adequately capture what it is like listening to music on these speakers, but I found that there was a bit more bass extension in my room that was lacking and wanted a subwoofer to help bridge the gap. I reached out to my dealer who recommended REL, saying it would pair perfectly with my system.
Unfortunately, the REL models I was looking at were simply too big for the space I had. Then I came across a glowing review of the SB17-R, and its dimensions were exactly perfect for the space I had. I talked to SVS, expressing my concerns that their subwoofer, while excellent on paper, may not be fast and accurate enough to keep up with my system. I was reassured that they would happily put up their subwoofer against any of the best and know it was more than capable.
So I ordered one, set it up, and let me tell you, it’s outstanding. It’s not working hard in my set up but it’s filling in the low end quite nicely and added just that little bit I wanted to feel the music in my chest. Couldn’t be happier.
I got to meet a couple of the guys from SVS at Audio Advice Live a few weeks prior and expressed my gratitude at…

I am in the process of upgrading my theater room to also be a dedicated 2-channel listening room. I have been taking room response measurements with my SVS Ultra Evolution Pinnacle front speakers, center channel, and two SB17 subwoofers for about two weeks now. I am driving this all with an 8-yr old SONY A/V receiver until I purchase new Anthem STR preamp and amp separates to complete the upgrade. All I can say so far is that I absolutely love the SVS Ultra Evolution Pinnacle line and your subwoofers.
Keep in mind that managing room acoustics is half the battle. I downloaded the free copy of REW measurement software (please donate to these guys - this is awesome) and got a good USB calibrated mic. With a little practice and following some theoretical guiding principles, I took tons of measurements to prove I found very good placements for speakers and subwoofers, and I adjusted what I could (speaker levels, sizes, crossovers, distances, etc) with my old SONY A/V, and I have already reached nirvana! Thankfully, your subs have plenty adjustments on their own, and this really helped my initial setup.
I don't even have independent subwoofer outputs yet (I will when I get the Anthem STR preamp), but after adjusting what I could, this system already sounds incredible. I was amazed at the improvement! Lower bass sounds are very full but not boomy in any way. Kick drums and other percussion sounds are crisp and in your face, as well as bass guitar notes. The vocals and…

This Sub replaced a 26 year-old B&W ASW4000 , which in its day was a great performing Sub. All I can say is that Subs have come a long way in that time! This SVS Sub is a huge improvement in every aspect - I really appreciate the combination of power and control, which is awesome for music and movies. Great value too!

One month with the SVS SB-17 Ultra R|evolution and my home theater has been transformed. That 17-inch driver is a monster. Phenomenal deep bass, huge amplitude, and it stays clean even when you push it to reference level. If you want earth-shaking bass for movies like Interstellar and Tron: Legacy, Deadpool and Wolverine (and killer musicality), this is it. Absolute winner from SVS.
