Articles is our blog where we share insights, information and opinions on subwoofers, hi-fi systems and the joy of sound. So, put on your favorite album, mix yourself a drink and kick back, you might be here awhile.
The first phase of the test was the basic question many viewers want to know upfront: which one plays the loudest and goes the deepest when used for theatre Both reviewers were absolute in their judgement that the REL T/7x clearly played significantly louder and extended deeper than the other subwoofers. They were stumped at how this could be so given the specs of the other subwoofers compared to the REL subwoofer. In fact, the reviewers wondered aloud about the accuracy of some of the other subwoofer specs.
Two subwoofers mean connecting one to each loudspeaker channel: left and right. With a single T/5x in play, we connect it to just one of the channels because, according to REL, bass content is assumed to be the same on each channel. This also sidesteps any potential problems with monoblocks or balanced differential amplifiers where the High-Level connection of a single subwoofer to both channels creates a common earth that might fry your amplifier. The risk is real folks, I had a close shave with an early REL. If in doubt, consult your dealer (REL has a wealth of information on the subject).
SetupTo recap: you juggle subwoofer position, crossover frequency, gain and phase until you get optimal sound. Rob Hunt has set up countless subwoofers so took it all in his stride. I lent a second pair of ears. I know not which parts of the process made the most difference but the end result spoke for itself.
You can survive with just a regular set of speakers. You don't, strictly speaking, need a sub. But you cannot believe the difference having one will make. It's not just the inevitable boost to the low end that comes from a good quality sub; it's the overall richness of the sound. In this guide, we've evaluated the top subs for this year, no matter what your budget, or the size of your room. For more background, see our subwoofer comparison table and buying advice below the picks. And to complete your system, see our articles on the best floorstanding speakers and home theater systems.
Above $1,000 is where you really start seeing subwoofers amp up the boom. The audio has a rich, subsonic presence that will rattle your stomach and shake the walls. It's one hell of a thing to experience. For large rooms (over 250 square feet) this is easily the best option. While other less-expensive subs like the SVS 3000 Micro offer more wattage, the JS12 seems to have more presence and room-filling power. It especially excels in home theater, giving movies and TV shows extra oomph and pizazz. Those with smaller rooms should opt for the less expensive 3000 Micro, but make no mistake: the Seaton Sound sub is still a beast.
However, the unusual driver/radiator design means that the Bravus II 12D needs a lot of effort to position properly. Although you should technically be able to position it as you would any other subwoofer, we found the positioning required a lot of fine tuning to get the best sound. The ELAC Debut 2.0 SUB3030, mentioned above, is not only cheaper, but is significantly easier to use. However, we still loved our Aperion Audio Bravus II 12D and believe it earned a spot on this list.See the Aperion Audio Bravus II 12D
With a frequency extension that goes all the way down to 16 Hz, the Power Sound Audio S3612 is second only to the KEF KC62 for anyone looking for the absolute deepest, darkest bass. It's the subwoofer we'd go for if we wanted raw, unrestrained energy, and hang the price tag. You also get an oddly-specific 1,920 watts of RMS power, making the S3612 the single most powerful subwoofer on this entire list. If you have a big room, and a bit of money to spend, you can tear reality apart.
Paradigm's new Defiance range of subwoofers comes in several flavors. The X series deliver raw power, while the V series is all about affordability. They are all good, and offer several advancements on basic subwoofer design, but if we had to pick one, it would be this one. In our opinion, it offers the best combination of sound quality, features, and pricing, and will be the best choice for most people. While we still wouldn't pick it over the ELAC Debut 2.0 SUB3030, which we think offers better value for money, it remains a good alternative.
You also get an excellent range of features, including app control of the subwoofer, included Anthem Room Correction, and the ability to make the subwoofer wireless with the purchase of an additional module. The Defiance range is a forward-thinking series, and the X10 is its finest ambassador. Paradigm, by the way, recently came out with a new line of subs, including one that retails for (gulp) $7,500. We've heard it, and it's superb, but that price tag puts it way out of reach of most people.See the Paradigm Defiance X10
In the case of subwoofers, size really does matter. To produce bass sounds, you've got to be able to produce a lot of energy. The bigger your speaker driver, the more energy you'll be able to put out (although a lot of it has to do with the amplification powering the driver as well). In general, you should be looking to acquire a subwoofer with a driver above 12\" in size - that's 12\" across, from end to end. Anything smaller will deliver good sound, but don't expect huge low-end power. The PSB Alpha S8 has a driver of 8\". We think it's good for small rooms, but you shouldn't expect it to put out huge energy.
Sealed subwoofers have a cabinet that is entirely enclosed, with no openings into its interior. Ported subwoofers have one or more openings, to allow the free-flowing movement of air. Put very simply: sealed subwoofers sacrifice a little overall volume and presence for a tighter, more controlled sound, while ported ones can pump out huge volume at the expense of a little clarity. Generally speaking, larger and more expensive subs tend to be ported, while smaller, cheaper ones do not.
However, we do recognize that DIY subwoofers are a huge market, and those who build their own spend a staggering amount of time getting it right. There are thousands of forums, subreddits, and other sites where builders post their work, and you'll often see DIY builders at audio shows. Hell, Dayton Audio even offer a basic starter cabinet, for those just getting into it.
Unlike many other speakers, subwoofer is comparatively easy, and it makes a great project if you're just getting started in the world of DIY audio. The components can be sourced from relatively little outlay, and you don't need a huge amount of electrical knowledge in order to build something you'll be proud of. While we will say that we aren't really the right site to find information on this, there's a wealth of information out there. If you get started, and you're not a giant ass-hat, you'll quickly find yourself making friends in the community.
In the past, the solution to this problem has been to increase the thickness of the surround to make it so strong it cannot buckle under the pressure generated, but this has two problems. The first is that the thicker the surround, the more energy needs to be exerted by the magnet/voice-coil in order to make the cone move, which reduces overall efficiency. The second problem is that the increase in the stiffness of the surround reduces the low-frequency response of the driver, which is the exact opposite of what you want to happen in a subwoofer.
Despite the welcome inclusion of equalisation circuitry to compensate for room position, you will still get best performance if you position the KEF in the place in your room where it is the best acoustic match with your room. (Which is true of all subwoofers, but becomes increasingly important as the subwoofer gets smaller in size.)
REL 212/SX Subwoofer Review Todd CooperiderFebruary 9, 2022Speaker ReviewsSubwoofersjQuery(document).ready(function($){ $(\"#cb-featured-image\").backstretch(\" -content/uploads/2022/02/rel-212-sx-subwoofer-featured.jpg\", {fade: 1200}); }); HomeReviewsSpeaker ReviewsUp NextKEF KC62 Subwoofer ReviewThe REL 212/SX subwoofer simply offers an entirely new level of bass reproduction in both 2-channel and home theater applications, and I have 2 of them in my media room for review!
REL makes subwoofers. Period. With that, they have a single focus on designing and creating the finest subwoofers on the market as they are not burdened with the development of other types of products. At the time of this writing, they have 13 different subwoofers divided into 5 different Serie, with prices ranging from Tzero MKIII at just $499 up to the No. 25 at $7,500. The subject of this review is their 212/SX at $4,999.
Also, what makes REL stand out is how they use high-level connections (speaker-level) as their primary and most effective setup as opposed to low-level connections predominantly used by most other sub manufacturers. This type of connection, combined with their advanced filter technologies, allows the subwoofer to receive the exact same signal as your speakers are receiving from the amplifier or receiver.
On the back of the REL 212/SX, you will find a lot more inputs and outputs than you normally find on a subwoofer, but these configuration options provide for a variety of ways to incorporate the subs into even the most complex systems. The most frequently used inputs, and the ones recommended by REL, will be your high-level Neutrik Speakon connectors for blending with your main speakers, and your LFE connections (offered in both RCA and XLR depending on your needs) for use in a home theater. You will also find an L and R RCA low-level connection, although REL recommends the high-level connections for best results whenever possible. In addition to the inputs and outputs, you will find an adjustable phase switch, a high/low-level dial, a separate LFE level dial, and finally a dial for adjusting crossover levels. 59ce067264
