This article is updated from time to time as new information becomes available. Last update 6/20/2016. Subwoofer 101 became the first SVS affiliate June 2016! It is not exclusive, meaning other quality makers are encouraged to participate!
This question has to cross a few minds. Is it better to go with a single giant sub that digs deep and has very high output? Or is it better to go with 2 smaller subs that dig almost as deep, but with a little less output, for the same price. The short answer is, “it depends”.
First off, you need to know what kind of equipment I’m talking about. I’m not talking about $200 subwoofers, I’m talking about high quality subwoofers. The big sub is a Hsu (pronounced “Shu”) VTF-15h MK1, a venerable powerhouse in the real world of bass, which I have enjoyed for over a year and a half. It is a 15” subwoofer, with variable tunability, such as both ports open, 1 port open, or both ports closed, as well as Q control. After shipping, it’s just over $1,000 and is a very large unit, capable of bass that will boggle your mind. It’s an excellent unit.
The dual subs are a set of SVS PB-1000 10” ported subs, which are more simplified. No port adjustments or Q control. They are currently the most economical sub you can buy from SVS. SVS sent out a set for me to evaluate for this site and this review in particular, and I see why they were eager to do so.
It is generally my recommendation to go with 12” or better, but these subs in particular demolished that barrier. They are the only 10” sub I can recommend with confidence, and that’s only after hearing what they can do. Prior to hearing them, I wouldn’t have thought they would deliver, and would have recommended something bigger. Come to find out, it is an SVS product at it’s core, which means excellent performance.
They are $499 each, or they give you a $50 break at $950 for a dual set. There are no shipping charges, even if you send them back.
Now some people may point out that this comparison is a little unfair, pitting the best of Hsu against the most affordable SVS model. It hardly seems like a fair comparison. However, if you have $1,000 bass budget, then these two options should be in your cross hairs. The benefits of duals are well known, and I can say with confidence that the benefit is very real. Some people may dismiss the PB-1000 as not being substantial enough, as I nearly did, but after my experience, I can say this would be a mistake.
Now in terms of appearance, the 2 PB-1000’s look almost “kid like” next to the VTF-15h. The words that came to my mind? “Not a chance”. These would be fun to listen to, but they weren’t going to be able to provide the same presence and authority as the big sub. In my mind, this was just going to be a fun exercise, and I’d be happy to bring the Hsu back out for duty when this experiment was over. I’ve been wrong before though…
The setup was easy, I just got a splitter and an extra RCA cable. I had to cut in a foam floor pad to make the right sub fit over the base of my speaker stand, it was a tight fit. For continuity, I put a foam pad under the left as well. This was not required, but I did have a large foam pad under the big sub, so it’s not like it would skew the comparison.
Later, having removed the pads for a different configuration, I found no noticeable effect as the standard rubber feet do a pretty good job. SVS also offers their more substantial SoundPath Subwoofer Isolation System that can be used for any subwoofer with screw in feet, and they DO provide a noticeable difference on my wood floor.
I had a little more wiggle room here, but still not much. My home theater is also my living room, so I can’t go sticking the subs wherever I like. This was a problem with the big sub. It only fit in one place: The corner. A sub crawl was pointless. It could only go one place. I talk about Wife Acceptance Factor, and this was a biggie.
The smaller subs fit on either side of the entertainment center, although the right one just barely fit. I could move the left one toward the corner or up tight against the entertainment center. I preferred the latter after some experimentation.
To spare you the hi-jinks my AVR played on me, once I got the crossover levels correct, I started running through tracks I was very familiar with. I don’t mess around, I went straight for E-40, MGK, Whiz, Young Jeezy, all of the hard stuff. If there was going to be any lackluster performance, these tracks would flesh it out.
You can find these tracks on my YouTube channel under playlists, as well as the Enjoying Your Gear page, but keep in mind they are not safe for sensitive ears. They have hardcore bass, and are great for testing, but not something you want your 6 year old listening to.
And boom went the dynamite! I was beside myself with the depth, cleanliness, and tightness. It was such a full and rich experience. Very satisfying. I kept looking at my wife, asking what she thought, as I really did not trust my own ears at this point! She backed me up, she said it sounded better, wherever she was standing or sitting. I could have written this sooner, but I still didn’t trust myself, and I didn’t want to lose credibility among my audience for such a substantial topic. Truly, I did not trust my own ears.
So I began asking my brother, my niece, our friends, anyone who had heard the big sub prior. All were echoing what I felt. Duals were better, and these PB-1000’s are incredibly good. After playing the moving bed scene in “The Haunting”, I saw a lot of open mouths and big eyes. “It sounds better than a movie theater” was something I heard repeatedly. It was the immersive bass that left that impression, I’m certain of it. The dual setup was everything it was supposed to be, so long as the subs are solid!
Does this mean the VTF15h is a dog? Hardly. 2 of them would be outstanding. It would also be more than I could personally justify needing, but headroom is awesome. It does dig a little deeper, but we are talking a few hertz. The only track I found where the big sub had a clear advantage was Saint Saens Symphony Number 3 “organ“, which is a pipe organ symphony, and at 7 minutes in it gets real. The bass tends to hurt your ears, even when properly reproduced. It’s really deep. The big sub handled it better, but it wasn’t as though the PB-1000’s gave up. They just didn’t do quite as well. Unless your listening habits revolve around this track, I don’t see this as a major reason to rule out the PB-1000’s.
Frankly, I’m glad I could find a “weakness” with the PB-1000’s. It’s hard to write about SVS without sounding like a groupie. It’s a common problem, and a great problem for SVS.
In terms of music, I listen to all kinds. Sarah Mclachlan, Slipknot, Norah Jones, Dead Sara, Ray Lamontagne, E-40, Anne Murray, Merle Haggard, Digital Underground, Metallica, Korn, Keb Mo, Pink Floyd, Eagles, I could go on. Both subs do great with all of that content. It’s hard to judge this against one another as I was not willing to listen very long to the PB-1000 as a single, not because it didn’t sound good, but because duals just sounded so much better.
Frequency response is a very grey area in the subwoofer world. Fair disclosure, I do not own an SPL meter. This site is for normal guys, and like most guys, I don’t have an SPL meter laying around, (now have a UMIK-1) although I don’t discourage it. Instead, I listen to sweeps and let my ears discern the peaks and valleys. The VTF-15h had some peaks in my room around 50-70 hertz. (I though it had some peaks, but after discovering my mains were causing peaks, I need to revisit this issue.) It was authoritative down to 17, which is why it handled Saint Saens so well. It’s an excellent sub that would do even better with Room Eq Wizard and a Mini DSP 2×4 to correct in room peaks, as any sub would. Corner loading also played a part I’m sure, so don’t take my observations as accurate or definitive.
The PB1000’s had softer peaks (not as dramatic) around 35-40. (again, mains were causing peaks) They produced clean, authoritative bass down to 21 hertz, and began to taper to 19 hertz, under which they really started to fall off. These would also do well with Room Eq Wizard, but did pretty well with Audyssey alone. Again, this may be due to having dual subs, but SVS is known for their flat frequency response curves.
More “common” subwoofers that are not on the same level as these two makers might list a response of 18 hertz, but really taper off around 30 hertz, producing some sound, but not with any real authority to speak of. Both of these matched their marketing material and their stated performance. Both companies are known for being spot on, and I can absolutely back that up. Both are great value for what they deliver.
So my conclusion comes with a lead heavy caveat. In order for it be beneficial, at least in my opinion, you need to have the smaller subs be as good or better than the PB-1000’s, which is a tall order. I would prefer a sub that has true authority at 20 hertz, but 21 hertz is not enough of a difference to make me want to pass these up considering they do still produce healthy response at 19. If I was buying subwoofers today, these would be my starting point, the minimum level of performance I would be truly happy with. This is not meant to be a dig on the PB-1000, quite the opposite. It’s an outstanding sub, even if it were more expensive. There are subs that exceed $5,000 that are only rated to 30 hertz.
I’m happier with the dual PB-1000’s than I am with the single VTF-15. If you are at all familiar with the real subwoofer world, then you know the flame war that is bound to descend upon me for speaking such blasphemy! Remember, I LOVE my VTF-15, and would really love a pair, knowing I could easily power a room triple the size. If I wasn’t able to find an extra $1,000 in my couch cushions, or in my wife’s budgetary approval, I’d have to go with the dual PB-1000’s. Anywhere in between or better would be great too. Dual PB2000’s would likely be a very low compromise solution, assuming you have the space.
The goal for my audience is to find subs that are good at everything. Never running out of steam, never being taxed to a point of sloppiness at sane volumes. The PB-1000’s fit that description quite nicely. If these are not your choice, the next step in my opinion would be 12” subs, which of course will be more expensive for similar or better performance. That’s OK, bigger subs are nice, it’s better to have too much rather than not enough. Just don’t go getting dual $200 subs and wonder why you aren’t thrilled. Quality makes a huge difference.
So for this particular scenario, I’d have to put my money on the dual PB-1000’s over the single larger sub (or any other single for that matter, including SVS, this wasn’t meant to be a brand comparison). There are a couple of reasons:
Duals are amazing, few will dispute that. In my opinion, duals should absolutely be part of your plan, if you want amazing performance. It resolved my dead spots and gave great saturation. It’s not a clever sales ploy, duals are worth it!
Compromise was expected, but there wasn’t nearly as much compromise as I anticipated. Given the amount of bass heavy content I bombarded these with, I’m beside myself with how well they do. Overall, they are impressive and surprising. The PB-1000’s are ridiculously good.
The ability to upgrade to the larger PB-2000’s or any other better SVS Subwoofer within a year, at FULL purchase value. This shouldn’t be your deciding factor, but it’s a really nice option. The trade in scenario is the only time I’m aware of that SVS will ask you to pay for shipping, which gets expensive with heavy subs like these.
No shipping charges, and a full refund if you need to send them back. You have 45 days to decide if they work for you. If you live in the LA area and can pick up directly from HSU, this is not a factor.
Visual impact. Better Wife Acceptance Factor. They are not nearly as imposing as the larger sub. Granted, I can always say, “sorry honey, it’s for the website” and put just about anything I want in my living room, but not everyone will have as good of an excuse. Good bass takes up space, and you should be prepared for larger subs if you want great sound. These just happen to be the smallest ported subs that I’m aware of that truly belong on this site.
So there are my thoughts. I can sincerely say that dual PB-1000’s meet my bass needs with gusto, and given the name of this site, that has to count for something. I would not be upset if they were the last subs I was able to have. It’s getting off the hook cheap for outstanding performance.
For the reasons above, and the fact that I will be very sad to see them go back to SVS, I can sincerely say that Dual PB-1000’s are the smartest buy in bass. I would recommend buying deeper response if you can afford it, assuming proper quality, but these are extremely satisfying and should leave no trace of buyer’s remorse. Even if they did, SVS has a stellar reputation for customer service. For a bass budget under $1,000, there is no question in my mind that these are the best bang for the buck, and I cannot comfortably recommend less.
Good luck in the search, hopefully this was useful!
