An icon of SVS subwoofer innovation, the cylinder-shaped cabinet design of the PC13-Ultra subwoofer lets you enjoy the performance benefits of a larger subwoofer, without sacrificing the floorspace required of a reference ported subwoofer.

Stunningly Potent 13.5-Inch Down Firing SVS Ultra Driver

Equally matched for music and home theater, the PC13-Ultra powered subwoofer boasts a 13.5-inch down-firing Ultra Series driver with dual high-grade ferrite magnets and an FEA-optimized motor for distortion-free performance at the most punishing drive levels. Dual linear-roll spiders and stitched parabolic surround allow the PC13-Ultra to move massive amounts of air and achieve extreme excursion capabilities while maintaining control over the ultra-light and rigid fiberglass composite cone, so it can start and stop on a dime with no overhang, even with the most challenging music tracks.

Powerful and Sophisticated Sledge STA-1000D Amplifier

Conservatively rated at 1,000 watts RMS and 3,200 watts peak power, the Sledge STA-1000D DSP amplifier inside the PC13-Ultra subwoofer delivers effortless power for maximum SPLs and sonic impact in movies and music, while maintaining pinpoint accuracy in frequency and transient response. It also has brains to match its brawn. A sophisticated DSP offers an array of filters and volume, gain, and phase controls for fine-tuning in-room performance. Plus, the efficient Class-D amplifier design consumes less than half-a-watt of power in stand-by mode.

Variable Port Tuning

Rated at 15-200 HZ +/- 3dB, the PC13-Ultra subwoofer features variable port tuning so you can adjust output and extension based on listening preferences. For connections, the home theater subwoofer features a stereo line-level RCA and balanced XLR input/output connections along with an 80Hz high pass filtered output connections, continuously variable volume and phase controls, and three top-firing 3.5-inch high-flow flared ports with large radius inner and outer flanges.

Effortless power and extreme low frequency extension without sacrificing detail or musicality, the SVS PC13-Ultra cylinder subwoofer delivers greater output per inch of floorspace than any traditional ported box subwoofer in existence. Musical bass is rendered with delicate refinement and toe-tapping aplomb while movie soundtracks are unleashed with chest-thumping slam and impact as well as mood-setting low frequency effects, all from a subwoofer that blends seamlessly with any speakers.

Reviews Summary
Customers say this subwoofer delivers powerful, room-filling bass that transforms their home entertainment experience. Many reviews mention feeling deep, low frequencies they never knew existed in their favorite movies and music. The cylindrical design, while large, helps save floor space compared to traditional box subwoofers. Users appreciate its versatility across both movies and music, noting its ability to produce clean, controlled bass without distortion. While some find the rear-mounted controls challenging to access, most praise its build quality and performance. Many become repeat purchasers, often adding a second unit to their setup.

    Dual PC13-Ultra
    Rated 5 out of 5 stars
    WOOOWWWW!!!

    These are by far the best Subwoofers I have ever heard or seen. I have been using them for one week now and they are literally a night and day difference from what I have been used to. I previously had dual subs from two differnt companies, the Polk PSW 111 and the JBL Base2/Basswave. I always felt that I was missing listening content in my music and movies but all of the stores locally that sold home subwoofers didn’t offer anything that pushed me to purchase any new ones. About four months ago I began looking into subwoofers online and ran across SVS. I did a ton of research and spoke with the SVS experts via text message. With their 45 day in home trial I finally decided to make the commitment and purchase the dual Ultra PC13’s. SVS will not be getting these back! Immediately I fell in love with the look of them and once connected,,,,, I’m hearing things in my music and movies that I never knew was there. I’m still playing around with the proper settings but “WOOOWWWW!!!” I love ‘em. Once you purchase these you won’t be able to go back, it’s the equivalent of first learning to drive, you never intentionally go back to walking everywhere. Awesome Subs!!!

    SVS ULTRA? INDEED!

    I purchased two SVS PC13-Ultra subwoofers. The choice, going SVS, was between these cylinders and the sealed cube model (SB 13-Ultra). The application was music only, but including organ and other deep bass requiring music, which bottomed out my previous subwoofers. The other gear: Magnepan 1.7s, Parasound Halo P5 preamp, Krell showcase power amp, Sony ES HAP-Z1ES music player and Music Hall turntable (thats enough, though there is more!). Well, I started off in the ported mode. I calibrated and measured with DSPseaker. Excellent extension down to 20 htz in very large living room (1200 sq ft, 8 ft ceiling), but sharp drop off thereafter, as expected of ported mode, Nearly flat response across the spectrum.. No problem with measurements, to say the least! But listening, the bass was, well, blow-hard! I knew those subwoofers were there, exaggerating and not integrating: tuneful did not describe the performance. So I switched to sealed. Now extension to 10 htz (-5 db), equally flat response. But listening,now I had bass beauty to die for! To be fair, SVS recommends the sealed mode for music, so I should have known. Granted, at plus100 db the ported (and its physics) might show some advantage, but Ill never hear it, thats too loud for me (and for my wood framed house!). I am feeling very pleased with myself for making this choice to purchase SVS.

    PC13 Ultra

    This is a impressive and fantastic subwoofer. I am from the belief that you can never have too much bass and the PC13 Ultra delivers. I started out with my 45 day free trial of a PC2000 and returned it with free return shipping paid for by SVS. I then purchased a PC12-Plus and returned that because although better, it was just quite not enough. Again, the return shipping was paid for by SVS 45 day in home trial. I then purchased a PC13-Ultra and BINGO!! Now, ultimately I would have preferred to have two PC2000's for about the same price as the PC13-Ultra but as many married men know that a marriage is a lot of compromise. That said my wife was not having any part of two subwoofers in our living room. Hence, one PC13-Ultra. Finally, the reason why I gave it a 4 star rating and not a 5 star rating is the silly volume control that SVS uses. I don't get it!!! -100 db to 0 db is the range. However, for all intents and purposes -100 through -90 is completely useless. The manual states when running the AVR auto calibration set it at -8 db's for small room, -5 db's for medium size rooms and -3 db for large size rooms. Something like that anyway as I don't have the owners manual in front of me. Common sense would dictate a 0 through 10 db volume control and leave it at that. I don't get it. I'm sure the engineers at SVS are much smarter than I and have their reasons, but I just don't get it. Hope this review helps anyone contemplating which subwoofer is best for their application. One…

    You Can't Touch this!!!

    Can't Touch This! That's what I think about when I read about other Brands out there to buy. I can't find one for the price that can touch this PC13-ULTRA even after 2 years of owning this Sub I'm just amazed at the thump! Our music has never sounded so good. When your wife of 40 years says why in the Hell didn't I find this years ago just after one song of hers I played after getting all the SVS speakers hooked up and threw her favorite album on the turn table in-which I love also, Physical Graffiti "Kashmir" When it started hitting and the wood floor started shaking under her feet I knew I was saved! The sub is , well no other way but to say Great. Yes people I can't thank Ed enough from SVS for getting me lined out on a complete line-up of their SVS Prime line of speakers which for my room size of 22'-6" long X 15'-4 " wide and 8 foot ceiling I just am blowed away by how great the PC13 ULTRA Sub sets the whole room off. I could go on about movies' and such but they changed over to the 4000 series of this sub and you can't go wrong there either. Just a Great Sub that will knock your socks off and as for me my wife loves that I finally have a great system for us to rock away the days and nights.
