If you're looking to measure a subwoofer unit with your 2.0 speaker setup, you can achieve this via daisy-chaining the speakers to the sub unit.Setting up a 2.0 subwoofer system for speaker measurementsYou can easily measure a speaker setup with an additional subwoofer unit. Simply route your L-R channels through the sub in a 2.0 stereo setup (daisy-chain). To do this, there will be input and output slots available at the back of the sub. In other words, if you are using the stereo version of the SoundID Reference Measure app, the subwoofer can NOT be routed on a third channel separately:How it worksWe are using the subwoofer's built-in crossover, which will take care of the low-frequency separation between the sub and the speakers. The speaker calibration profile will then work for the entire setup at any given volume. There will be no need to make any separate volume adjustments on the sub after completing the measurements.In fact, if you make adjustments on the sub separately after completing the measurements, you might need to recalibrate as the correction balance between the speakers and the sub has changed.Tips and tricksSetting up a subwoofer for the perfect measurement can be a little tricky, especially with all the physical settings options on the back of your subwoofer unit. Set the subwoofer level to your liking, perform the measurements and follow these tips:Don't change the speaker/subwoofer level and placement relations after calibratingIf the low-frequency correction is exceeding 6 dB, go back and turn down the subwoofer a little, then measure againIf you can't get a good reading and the applied correction seems extreme, you might have a problem with a room mode: try a slightly different placement for the sub and measure againIf the measurement suggests that there is still a problem/room mode present, try adjusting the available settings at the back of the sub (Crossover, Phase Inversion, LPF, etc.)Use the Limit Controls and Custom Target controls in the software to fine-tune the correction:Not enough bass after calibrating a subwoofer setup?If you are concerned about SoundID Reference cutting out too much bass from your sub, you can always adjust the correction using the Limit Controls and Custom Target controls in the software!However, it is most likely that the calibration profile is accurate, and your ears simply need some time to adjust to the change. If you still have doubts, simply test by working with the new calibration profile and see how your mixes translate - if the bass response is translating well on other playback systems, everything is working as intended and the calibration profile is accurate!

(Image credit: Getty/Thatree Thitivongvaroon)Mixing music in 5.1 surround is exciting, but the price of equipping your studio for the task might seem prohibitive. If you limit yourself to professional equipment, things can get expensive quickly. Does that mean that 5.1 surround mixing is the exclusive domain of the rich and famous, or is there a way to do it on a real-world budget? By adding some consumer gear to your existing project studio, you can mix 5.1 surround for a lot less than you might think.To monitor 5.1-channel surround music in your studio, you need five full-range speakers and one subwoofer, amplifiers for the speakers and subwoofer, a volume control with bass management, and a Dolby Digital/DTS decoder so you can check that the final surround encoding worked.Fortunately, a modern home-theatre receiver (also called an A/V receiver) takes care of those major monitoring requirements (except the speakers and subwoofer) in one fell swoop. All home-theatre receivers include Dolby Digital or DTS decoders (or both), which accept a digital bitstream from a suitably encoded disc in an appropriately equipped DVD player and then convert it to six audio channels. In the studio, that conversion ability is important only for checking a file that has been encoded; it is not used during the mixing process. However, make sure that your receiver has both decoding types, just to cover your bases.More important for mix monitoring, all A/V receivers provide amplification for the five main channels, but few include an amplifier for the subwoofer, which means you'll need a powered sub. Many receivers also include preamp outputs, which let you use external amplifiers or powered speakers.A large knob controls the volume of all six monitor channels simultaneously, and a bass-management filter directs frequencies below a certain point in the main channels to the subwoofer. Basic receivers have a fixed bass-management frequency (typically 80 Hz), but more expensive models let you select from a list of cutoff frequencies. To gain access to that and most other parameters, the receiver must be connected to a video monitor so you can see its on-screen-display (OSD) user interface.For project studios, it's important to use a receiver with six discrete analogue inputs. Those inputs are intended for the new DVD-Audio and SACD players, which have six analogue outputs. In the studio, however, those inputs are perfectly suited for accepting the 6-channel output from the mixer or multitrack mixdown deck for monitoring purposes.Basic A/V receivers that provide 60W of amplification per channel can be purchased for less than $300. You can also spend$1,000 to $1,500, or more, for a high-end receiver with time-delay correction (which compensates for speakers placed at different distances from the listener), calibration microphones(for automatically adjusting speaker.

The dedicated surround satellites mean the bar can deliver a more immersive sound than setups without satellites. For instance, it's easy to make out sounds passing from front to back and left to right in this setup. These satellites don't put out much bass, but that's okay, as the subwoofer handles those frequencies. They also lack a little clarity, which can rob sounds like clashing swords of some shimmer.

Only the bar itself has up-firing drivers, not the satellites, which limits the sense of height the system can produce. The up-firing drivers do add some sense of verticality to your audio, but never make you feel truly immersed in a vast soundscape. Sounds feel like they come from above the bar, but not from above you. The satellites do a good job representing detail, so you can easily pick out sounds like a helicopter zooming around you, but less well when something flies over you from behind. The subwoofer also delivers a solid amount of rumble in bass-heavy scenes without overwhelming the mix.

Tips for Setting the Proper Crossover Frequency of a Subwoofer The crossover frequency of your subwoofer is the frequency at which your speakers start to roll off and your subwoofer kicks in with LFEs and bass notes. Most modern AV receivers feature an auto EQ program that will assign the proper crossover frequency automatically based on the capabilities of your loudspeakers. It’s generally best to leave these settings where they are.If you’re using an AV processor, preamplifier or a DSP subwoofer to adjust the crossover frequency in a two-channel or surround sound set-up, here’s a few tips to get the best performance possible. As with any bass management functions, it’s helps to do some critical listening and experimentation to achieve the best sounding results. Check out the entire SVS Subwoofer line-up to choose the subwoofer that is best for your TV/movie viewing. If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanlyThe most common crossover frequency recommended (and the THX standard) is 80 Hz.The numbers below highlight general guidelines for speaker/subwoofer crossover frequenciesOn-wall or Compact satellite speakers: 150-200 Hz.Small center, surround, bookshelf: 100-120 Hz.Mid-size center, surround, bookshelf: 80-100 Hz.Large center, surround and bookshelf: 60-80 Hz.Very large center, surround, bookshelf: 40-60 Hz.Tower speakers with 4”-6” woofers: 60 Hz.Tower speakers with 8”-10” woofers: 40 Hz or Large/Full-Band (i.e., full-range).If you’re unsure about your speaker’s ideal crossover frequency, try our SVS Subwoofer Matching Tool, which will recommend the ideal SVS subwoofer for your speakers and tell you the best crossover frequency.Listen for a smooth transition between speakers and subwoofer. Ideally, the blending will be so seamless, you won’t be able to localize the bass and everything will play in unison.If you’re noticing a bass bump at the crossover frequency, try adjusting the volume control to match the output of your main speakers.For a deeper dive into crossover frequencies, check out our Digital Bass Management Primer.SVS Ultra, 4000 and Plus Series Subwoofers feature powerful and sophisticated Sledge DSP amplifiers that allow you to adjust crossover frequency, room gain and other settings directly through the subwoofer.If you have any questions about setting the crossover frequency or system set-up in general, leave it in the comments or contact our Sound Experts at [email protected] makes a variety of powered subwoofers with DSP amplifiers to fit every room, audio system and budget.

App functions like a remote, allowing folks to seamlessly switch between USB and Bluetooth connections, turn the volume down, and access those aforementioned features under Bluetooth.When using the EQ over Bluetooth, the audio quality sounds a little worse. I hate how many functions are tied to the software, especially since the software has been giving me so much trouble as of late. It sucks that the only way I can cycle through presets or enable THX spatial audio is through Synapse. I also hate that I have to download two different apps to control music and RGB settings. The software inconveniences most definitely drag down this otherwise enjoyable sound device, especially since the original Leviathan had physical buttons you could use to control the EQ.Bottom LineThe Razer Leviathan V2 is a great soundbar with volume, high treble, and a thumping subwoofer that leaves a lasting impression. Both the soundbar and the subwoofer have sleek, matte-black designs that will blend easily into any RGB-powered setup. The streamlined redesign comes at a cost, though — while the original Leviathan had more physical buttons, a 3.5mm jack, and an optical audio input, the V2 has none of these features. It does have Bluetooth, which is a nice addition, but Bluetooth sound quality can’t compete with a 3.5mm or optical connection. Also, while I love the V2’s new RGB lighting and software features, Razer Synapse 3 was so janky that I couldn’t really enjoy it. You may not face the exact same issues I did with Synapse 3, but it’s a finicky program that you’ll need to use if you want to fully experience the V2.At $249, the Leviathan V2 is somewhat pricey, but you’re paying for quality sound. If you’re looking for a new soundbar with more flexibility, also consider the Creative Sound BlasterX Katana, which also features a subwoofer, 7.1 Virtual Audio, and programmable RGB lighting but has physical buttons and more connectivity options. However, if you plan to use your soundbar over USB and want great sound, the Leviathan V2 is a strong choice.Isaac Rouse is a staff writer at Tom's Hardware. He reviews laptops and various gaming peripherals.jcrownI must say, a 55-inch downward-facing subwoofer would be hard to place under my desk. Furthermore, I suspect it would probably break every window in the house (provided it's properly amplified, of course). Unless it's very, very efficient, I'm not sure what the
