In ported max output mode, it averaged In ported max headroom mode, the respective numbers were In sealed max headroom mode, they were The VTF-2 MK5 offers both line-level RCA stereo inputs and speaker-cable inputs, so it can work with any surround-sound receiver and with any stereo receiver or preamp. The SB Pro is basically the same as our former also-great pick, the SB, with the addition of an app-controlled equalizer that allows precise tuning of the bass levels at different frequencies—so you can make the bass sound more or less!
When we tested the original SB, our panelists all liked its punchy, precise sound when they were listening to music, although even with the size of the sub concealed, it was obvious to them that the SB was no home theater bruiser. Although we found that the EQ could make the SB Pro sound even smoother and better defined when playing music, it did nothing to help the subwoofer reproduce the lowest bass frequencies, which are necessary for realistic reproduction of movie soundtracks.
However, for a small home theater system, played at modest levels, the SB Pro will get the job done. The Bluetooth-connected smartphone app links quickly to the subwoofer and allows precise adjustment of such functions as volume and crossover frequency, as well as selection of Movie and Music listening modes plus a user-programmable Custom mode. The big advantage of the app is the parametric equalizer, which allows you to boost or cut three different bands of audio; you can select the frequencies and widths of these bands in the app.
Using the pink-noise generator and audio spectrum analyzer included in the inexpensive AudioTool Android app, connected to my sound system via Bluetooth, I was able to quickly adjust the parametric EQ to get an even, flat bass response from my listening seat, and then from there to fine-tune the sound to my liking.
These numbers are, respectively, 0. It outperformed the Rogersound Labs Speedwoofer 10S by 1. The SB Pro has line- and speaker-level inputs and line-level outputs.
Thus, it can connect to any receiver or preamp with a subwoofer output or a spare line output, and it can also connect directly to speakers or an amp in systems that have no subwoofer or line outputs. Many Wirecutter readers are concerned about how the manufacturing, shipping, and normal use of the products we recommend impact the world.
The former is a big plus. The latter should be a plus, ideally, because most electronics contain many recyclable materials, but the methods of recycling these products may have their own adverse impacts. In addition, we looked at how much power each subwoofer consumes in standby mode. First, some general notes. Almost all subwoofers can be repaired, in most cases by any audio-gear repair shop or even by technically proficient owners. The metal parts inside a subwoofer, including the metal woofer frames and amplifier heat sinks, are generally easy to remove and can be recycled at e-waste facilities.
But the enclosures, for the most part, are made from medium-density fiberboard, which cannot be recycled, and the recyclability of the circuit boards is, as with all circuit boards, technically possible but practically questionable.
Those numbers are in the same range as the standby power consumption of a typical TV set. Of course, both electrical consumption and cost increase the more often you use the subwoofer and the louder you play it.
Sound United, the parent company of Polk Audio, says it is currently working to create and implement a set of sustainability policies, and that the HTS 10 and its packaging are not made from recycled materials and are not recyclable.
The electronics are analog and do not use firmware, and thus cannot be updated. SVS says that most of the packaging for its subwoofers is recyclable. Several new subwoofers were introduced in conjunction with the CEDIA Expo , and we hope to get some of them in for our next round of tests. Following are brief notes about the other subwoofers and subwoofer-related products we tested. The complete CTA results for all of these subs and many more are available in this spreadsheet.
Definitive Technology SuperCube : The ultra-compact SuperCube , measuring less than 11 inches on all sides, sounded pretty good in our tests, but it fell well short of the slightly larger SVS SB in its deep-bass output.
ELAC Debut 2. Its reproduction of midbass tones was excellent, but our panelists found its low-bass output lacking. KEF Kube 10b : This sleek subwoofer looks nice but is a little expensive for the output it offers. It would be great for a small, high-quality audiophile music system. Q Acoustics S : This slim sub looks great, is easy to hide, and is fairly affordable, but we found its low-bass output to be particularly weak.
SVS Micro : This tiny subwoofer is only about half the size by volume as our also-great pick, the SB Pro, and it adds the same advanced, app-driven signal processing.
Brent Butterworth, Subwoofers: 4, 2 or 1? Brent Butterworth is a senior staff writer covering audio and musical instruments at Wirecutter. He regularly gigs on double bass and occasionally ukulele with Los Angeles—area jazz groups. How we pick and test Panel testing. Our pick. Rogersound Labs Speedwoofer 10S Superb all-around performance The Speedwoofer 10S offers an ideal blend of bass power and finesse in a compact and affordable package. You'll be amazed how different the bass sounds just a few feet apart.
You might get a ton in one place, then move just a few feet forward, and get next to nothing. Because the low-frequency bass waves are so long, they interact with the room itself quite significantly.
Room acoustics are cool. Another option is multiple subs. Again, this doesn't necessarily mean more bass; the goal is better bass. Multiple subs in different locations interact with the room differently because of where they are. Check out Multiple subwoofers: If one's good, two are even better and Brent Butterworth's epic Subwoofers: 4, 2, or 1?
Steve Guttenberg has written a great article on subwoofer setup I recommend you check out, called, not surprisingly, How to set up a subwoofer. EQ Certain subs and many receivers have room EQ processing, which plays test tones through your speakers and subwoofer and generates a room-specific equalizer setting.
These can do a lot, helping to minimize peaks in the frequency response over-accentuated notes. They can't fill a gap, however, in frequencies that the room acoustics are making hard to hear. These systems aren't magic.
They can't make a cheap, underpowered sub sound like a big high-powered one, nor can they fully counteract the negatives of poor sub placement. They do, however, help, and are worth looking into if you have the option. In a small room, a small sub will work just fine Small, in my parlance, is a or inch sub with at least watts. In larger rooms If your room has open walls to the rest of the house, you'll need even more power or a larger sub, as the bass sound will need to fill the entire space.
Placement is crucial, and a little time spent finding the right position can reap huge benefits in bass sound quality. Good bass vs. This is bad bass. Volume at the expense of quality. A quality subwoofer, placed correctly in a room, can produce deep sounds realistically, not just the thump-thump. The idea with any speaker system is to accurately recreate all frequencies in the audio spectrum equally.
So the best subwoofers don't make a boom sound, but just stronger bass than is possible with small speakers. Good bass isn't necessarily more bass, just better audio fidelity. A more realistic audio representation of what's in the music or movie.
If you want to add more bass than that, you can turn certainly turn it up, but the key is that you don't have to. The problem is, specs alone can't reveal a quality subwoofer over a bad one. They may lead you in the right direction, but a well designed inch, watt sub might sound great, and a poorly designed inch, watt sub might sound terrible.
This is where reviews come into play, and are worth seeking out. You can check out our reviews here. So there's no rule like "inch watts for 'X'-size room," but generally speaking, larger, higher-powered subs will probably work better, even in smaller rooms. If you have a large room, or one that's open to the rest of the house, a inch, watt sub isn't likely to cut it. In fact, it's probably safe to consider inch, watt subs as the minimum. Be wary of subs with less than watts, and if the driver is smaller, you'll need a lot more power.
And the numerous listening sessions has truly convinced us that this was the right way to go. Adhering to the low-loss sound design principle, the surround of the woofer is built to allow long and linear excursion. The oversized suspension is designed to allow both weak and strong transients to turn into undistorted acoustic signals.
The enclosure comes in a choice of Black Ash and White laminate finishes - with an updated front baffle in mat satin finish. The entire cabinet is effectively decoupled from the floor by means of four polymer based oversized spikes. Appearing to hover above the floor the distance of 30 mm eliminates any potential turbulence from the space between the cabinet and the floor itself.
Still, the proximity to the floor ensures that the benefit of having a down-firing vent is maintained; a higher efficiency and more freedom in positioning. Any risk of port noise derived from the down-firing bass vent itself is seriously reduced by its convex tapered design.
Apart from the shape of the flares the vent has also undergone extensive testing, measuring and listening when it comes to dimensions and placement, in order to optimize interaction with the cabinet and woofer. UK Read the full review. Find your local dealer.
