Welcome

In my strong opinion, a subwoofer should be audible and authoritative down to 20 hertz, and have a relatively flat frequency response while doing it. Not just make noise, but be heard clearly and powerfully. Simple enough, right?

Most commonly available ported subwoofers sold in stores do not have the ability to produce quality sound below 25-35 hertz. There is a “secret world of bass” where you can get subs that go down to 20 hertz with authority and clarity, and it’s fairly affordable, all things considered. You can spend over $5,000 on a sub that won’t reach 20 hertz. Why pay that much or more for something “incomplete”? I tend to gravitate to subwoofers that are more value based, and I list subwoofers that I would consider buying myself here: Best Subwoofers “The List”

Even a lot of high end professional ported subs used at theaters and concerts are only rated for 40 hertz, so what are you missing? The “WOW” feeling we all hope for. You won’t know it until you’ve heard it. The visceral feeling I get at home is more substantial than most movie theaters. That’s an insane statement, and it’s a LOT of fun!

Theaters may have more loudness, but for the home you can have more controlled deep bass with fewer bleeding eardrums, while still being able to go louder than I am personally comfortable with. I prefer sound quality over maximum volume. Some Imax theaters produce comfortably down to 23 hertz according to the video below. The most economical subwoofer I recommend is measurably comfortable at around 21 hertz, and clearly audible at 19 hertz. Amazing for a 10 inch driver, and absolutely uncommon.

It’s important to understand that frequency response numbers are commonly misleading, and a sub accurately rated for 19 hertz can trample all over a sub “factory rated” for 16 hertz. Confused? I was too, and seriously frustrated! I’ll try to simplify as much as I can. I’ll try give you the basics, show you some specific examples of quality subwoofers, and you can take it from there.

My goal is to help save my audience some time, money, and frustration. I don’t mean to make anyone feel bad about their current subwoofer, just bring your attention to what is available for when you do decide to upgrade. Spending good money on audio and getting that unsatisfied feeling is no fun. There are a lot of good brands out there, but the really great subwoofers are known to very few, or they are crazy expensive. I don’t focus on the crazy expensive, I’m more value conscious.

Have a look around, the subwoofer is not as simple as some might believe, and just because a brand is well known does not mean everything they offer is top notch. There are a handful of brands that produce excellence, and they will be discussed quite a bit.

About

This is a site designed to simplify the search for high quality home audio and bass, with a strong emphasis on value. I’m essentially sharing my successes and failures in home audio, and aside from this project, I’m a layperson who has never worked in the audio industry. I’ve figured a few things out, and I’m still learning as I go. 

I started doing buying guides on YouTube, focusing on purchases that can break your brain. Having severe Fibromyalgia, my brain gets broken pretty easily, so I started doing reviews that I would have found useful myself. Paying it forward I guess, as other reviews had helped me make decisions.

I’m a limited one man show because of my health, something you will notice in the lack of production value, editing, and action in my videos. I shoot a few videos at a time when I feel good enough, which is about once or twice a month, so I have to be efficient. Hopefully that doesn’t ruin your experience, it’s the best I can personally manage.

I don’t sell anything directly (yet), but I do add affiliate links that make sense in order to pay the electric bill and kibble for the talent, so if you follow links and buy almost anything, it could earn commissions for this site, even if it’s not related to home theater.

Clicking an Amazon link to a movie, and then buying a dog toy for your own furry friend, or nearly anything else, can earn a commission for this site. I don’t ask my audience to do anything for me that would cost them anything extra. Likes, comments, shares, and subscribing are all free, and all are valuable to me.  

It would be MUCH easier to make money with less expensive and more recognizable brands, but I think it would leave my audience short-changed. In that way I am limited. I could easily promote overpriced clock radios simply because of name recognition, but I’m not Forrest Gump telling little white lies about ping-pong paddles.

Performance must be spot on for me to discuss a subwoofer in a positive light, and I’m fortunate that a few of my favorite sub makers have been interested in offering their support. Can’t hit down to 20 hertz cleanly and with authority? It won’t make the list.  

It’s easy to find main speakers that produce from 100-20,000 hertz. Finding a sub that works well and evenly across the range of 20-100 hertz sounds simple enough, but that’s exactly why this site exists. It’s fairly uncommon.

This site is designed for simplicity. You can find brain splitting tech anywhere. I’m condensing it (feel free laugh, I know I’m long winded) for regular guys who just want better sound without having to earn a double doctorate in the process. It gives me a headache, so I know others have the same problem.

These are just my thoughts, and they will change and evolve. I’m a guy with a camera and an internet connection who finally found great bass, and I felt like I should share it with the rest of the world. Good bass shouldn’t be limited to those with $20,000 + home theaters and engineering degrees. Regular guys can have it too, if they know where to look.

Getting my bass proper has been the most dramatic improvement to my home theater so far. Enjoy the site, and please comment, especially if you disagree, that’s how I learn.

How to buy a serious home subwoofer

A quality subwoofer will not distort under lower frequency sound like many common subwoofers do. Many names associated as “top quality” have little real subwoofer performance. Almost any subwoofer will work well at 60 hertz, but once you get under 40 things get real. Under 30, and things get very real.

It would be easy to name a few brands that stick out for being overpriced, floppy, and breathless, but the goal is not to bash brands that may make future improvements and be worthy of praise. The hope is to change the industry and move it towards performance rather than hype, and do it by promoting those who are doing it right.

It’s better to discuss brands and individual subwoofers that do provide the performance that satisfies the need for clean, accurate, substantial performance at the lowest levels you are capable of hearing, and then some.

The focus will be on reasonable value subs, which will range from $400 to $2500. If I find a subwoofer that is outrageous under $300, I will absolutely discuss it. In fact, I will celebrate it. It’s just too hard to obtain amazing performance at that price point.

A few things to keep in mind:

  • Physics matter. To get substantial performance from a ported sub, you need a big box and wattage. There are a few small subwoofers that get down pretty good for there size, which typically rely on a passive radiator design, but for life below 30 hertz, they begin to lose the battle to distortion and output. While impressive for it’s size and great for small spaces, the cube subwoofer I had just wasn’t enough. The smallest ported sub I have heard that I can confidently recommend is the SVS PB-1000, which is still sizable for a 10″ subwoofer. It has been my one exception to my 12″ or better rule, and they hit all the way down to 21 hertz with authority, and don’t fall off until 18-19 hertz. It has the same rated response as the passive radiator cube design did, but the difference is substantial, with the passive radiator design falling off at 30 hertz. Lesson? Rated frequency response can be very misleading.

 

  • Manufacturer rated frequency response. Few big brands advertise realistic numbers. They are almost always inflated. Some brands do not advertise frequency response numbers at all(?!), instead suggesting you should rely on your ears. If they advertised their actual frequency response with graphs, their home theater in a box sales would plummet. The only way to judge truly frequency response is through independent testing, or your own ears using challenging tracks and test tracks that can be found on the Subwoofer101 YouTube channel playlist under Subwoofer test tracks.

 

  • White van speakers. Never, ever buy speakers out of the back of a van. EVER. They are universally garbage, and it’s a scam that has been going on for days.

 

  • Internet Direct brands. Makers that are internet direct rely a great deal on word of mouth advertising, and therefore actual performance. From what I can tell, they keep more profitability by not having to share revenue with brick and mortar stores. So when you buy a factory direct speaker for $1,000, it would have to be priced at $1,400-$1,800 to have the same profitability in a brick and mortar. That is not an endorsement of all internet direct brands, some aren’t that great, but a suggestion to look at some celebrated, quality internet only brands. It is not to say all brick and mortar sold brands are bad, but chances are you are going to have to pay much more for similar performance and quality.

 

  • Amp makers. The company that makes your favorite receiver probably doesn’t make the best speakers/subwoofers. Again, this may change in the future, but as of 2017 that is the case.

 

  • Beware of “systems”.  Speaker “systems” that do NOT allow for third party subwoofers (a different brand subwoofer) to integrate should be carefully scrutinized. The same is true if you cannot use dual subwoofers, an important part of quality bass performance. If you are buying a brand that only allows that particular brand’s subwoofer to be used, then you are limited. This is true of some wireless setups that may fix the problem in the future, and some bigger name systems known for their ultra compact design that should probably be avoided altogether. A wireless setup may suite you, but you can’t expect absolute deep bass performance, at least not yet. This is not referring to wireless sub kits, which are great for placement flexibility, but any wireless kit will add delay and can complicate things. Never try to mixed wired subs with wireless subs.

 

  • You can always turn it down! Getting an under-powered or shallow subwoofer is a bigger problem than going too big. Particularly in a big room like my 24×24 living room, which is open to 1,200 square foot house, there is little pressurization, but a pair of PB-1000’s filled it up nicely. I would always make dual subwoofers a priority, and going a little smaller with duals is OK. Any sub on “The List” should fill most normal rooms under 25×25 feet, assuming sane but substantial listening levels.

 

  • Placement. Subwoofers have a longer sound wave, and the features of your room will affect your subs performance. In my room I have dead spots, caused by what’s known as a standing wave, common with single subwoofers. As the frequency changes, loud spots and dead spots shift within the room, causing what I call “Swiss Cheese Bass”. Going with separated dual subs has resolved the dead spots in my room. A sub crawl is ideal for a single sub, but in my circumstances I could only move it within a 4 foot footprint for aesthetic reasons, which brings us to our next topic…

 

  • WAF. The Wife Acceptance Factor, or more politically correct SOAF (Significant Other Acceptance Factor) is a real consideration. I auditioned a small footprint, passive radiator design cube subwoofer, and my wife loved it’s look because it didn’t stand out, but it just didn’t perform. With my 15 inch sub, it was definitely a stand out feature. There was a little dread on her face when I unpacked it due to it’s size, but when it went live she was hooked. The sound quality outweighed the visual impact. SVS sent out a pair of PB-1000’s for review, and they have been the best compromise, but the PB-2000’s just seem to fit next to the TV stand the best. Solid performance with a small visual impact, and they also happen to be the most affordable.

  • How low? The human ear hears down to about 18 hertz (sometimes lower) for the best of us, most of us hear around 20 hertz, and your ability to hear low frequencies deteriorates with age. So why get a sub that actually goes down to 18 hertz or lower? Because if you have a sub that does well at 20 hertz, it will likely do great at 30-40 hertz where a lot of subs reach their real limits.  When you listen to that challenging track that would tax most common subwoofers, and instead you hear the sound that was actually recorded, as it was meant to be heard, it’s quite satisfying.

 

  • You also have the issue of how “flat” your frequency response is. Many common subwoofers vary widely in their measured curves. Many drop off substantially under 30-40 hertz. Many makers measure lower on that curve (even if it’s within accepted standards) , and when you listen to a 25 hertz tone and a 60 hertz tone, the 60 hertz tone is much louder. This is true for almost any sub, but how much of a difference is the key.

I have not listened to every subwoofer out there, but you can be sure I will not put a subwoofer on this site if it is not outstanding, or had a special merit.

 

If you are a manufacturer and want to have me review your subwoofer or otherwise believe your sub should be on “The List”, you can contact me through the contact page. My goal is to put really good products on a pedestal, not hurt brands that are still improving their products. I’ve set a nearly impossible standard, and I’m fully aware of that. Flat response curves, no bad manners, authority down to 20 hertz and reasonable output for no more than $2,500. I know there are some great subs that I have not heard of yet, so feel free to chime in.
