CHOOSING THE RIGHT SUBWOOFER

It’s always best to contact our Sound Experts to discuss your needs and requirements so that we can recommend the best subwoofer for your particular system and application. Helpful information to have ready includes:

  • The primary usage for the system (music, movies, gaming, HDTV, etc.)
  • A description of your system, particularly the loudspeakers and A/V receiver or surround sound processor.
  • Room size (including other contiguous/adjacent open spaces).
  • Distance from the subwoofer to the listening position.
  • The typical/desired playback level (low, moderate, loud). If the system will primarily be used for movies, the overall playback level and the desired level of slam/impact/pressure on bassy action scenes is particularly important.
  • Any restrictions on overall size, weight, height, footprint.
  • Décor, aesthetic or visual impact considerations (e.g., a mixed-use living/family room might require less visual impact from the subwoofer than a dedicated home theater).

Within each family (i.e., NSD, Plus, Ultra) the ported cabinet and ported cylinder subwoofers offer the same overall level of performance. While taller, the ported cylinder models have a smaller footprint than their ported cabinet counterparts and are a popular choice where floor space is limited, but there are no height restrictions.

The compact sealed subwoofers deliver excellent sound quality and balanced performance on music and movies while maintaining a smaller overall size/weight/footprint. The compact sealed subwoofers are an outstanding choice in listening environments which have more stringent décor or aesthetic considerations and require a lower visual impact from the subwoofer.

The ported subwoofers generally deliver higher maximum output at the deepest frequencies due to the efficiency advantages offered by the larger enclosure volume and porting system. They are a great choice in larger listening environments where higher playback levels are typical, and greater levels of slam/impact/pressure are desired on bassy action scenes. The ported subwoofers are larger in overall size and have more visual impact than the compact subwoofers, so check the available space and décor considerations to ensure good compatibility.

Subwoofer Connection and Placement

A single RCA cable is needed to connect between the subwoofer output jack on the A/V receiver and the Left or Right line level input on the subwoofer.

SVS offers SoundPath audio interconnects in various lengths, and these work great as a subwoofer cable, and also as a full-range interconnect for CD and DVD players and external amplifiers too.

Make sure to account for horizontal and vertical distances and corners when estimating the length for your subwoofer cable – it’s always better to have a bit of extra than not quite enough.

The variable tuning option allows the SVS owner to adjust how deep the subwoofer will play.

The standard/native operating mode is 20 Hz with all ports open. The 20 Hz mode provides the most muscular and powerful presentation over the most common bass frequencies, and will provide a usable in-room extension to 17-18 Hz.

If a single port is plugged and the amplifier Subwoofer Tune is adjusted to 16 Hz, the subwoofer will provide a usable in-room extension to 13-14 Hz. There is a slight loss of maximum output capability over the more common bass ranges when the deeper 16 Hz mode is selected, but many enthusiasts find this trade-off well worth it for digging deep into the infrasonic region on DVDs and certain music tracks (like acoustic pipe organ).

If all ports are plugged and the amplifier Subwoofer Tune is adjusted to Sealed, the subwoofer will start to roll-off around ~32 Hz and will have a broad/shallow roll-off profile. This shallower roll-off profile is often an excellent match to the acoustics of a smaller room which has a lot of ‘room gain’ (i.e., a rising low-end response), and Sealed mode in a smaller room can often exhibit usable in-room extension to 15 Hz or deeper!

The bottom line is that the SVS variable tuning options offer the enthusiast the ultimate in tuning and deep extension flexibility to meet the needs of a wide variety of room sizes, playback levels and listening applications.

Dual subwoofers are a great option for the enthusiast who can accommodate two subwoofers in the listening area. The benefits of dual subwoofers include increased dynamic headroom and a smoother bass response at more listening locations in the room.

Dual subwoofers are also harder to localize than a single subwoofer, which might be an important consideration for the enthusiast using very small speakers which require a high speaker/subwoofer crossover frequency.

Finally, two smaller subwoofers can often fit better into a room than a single larger subwoofer in terms of available floor space and visual impact, while offering similar or better performance as the single larger subwoofer.

Since the Left and Right line level inputs are connected and summed internally, A Y adapter is not required, and you may connect the subwoofer cable to either the Left or Right line level input.

Below are the best practices for piano gloss maintenance and care:

  • Dry dust only with a microfiber duster.
  • Never dry wipe the surface, as this will embed surface contaminants into the finish and cause micro-scratches and scuffs.
  • If cleaning is required, use a microfiber duster first, and then follow with a lightly damp microfiber cloth. Wipe only in straight, long-strokes in one direction.
  • Micro-scratches and scuffs may be gently removed (after dry dusting and damp wiping) with a high-end automotive polish which is rated as safe for clearcoats and is specifically designed to remove micro-scratches. Apply the polish gently, and avoid polishing on edges and corners.
  • After polishing, apply an automotive finishing spray to help protect the finish, add shine and also provide anti-static properties to help repel dust.

DIGITAL BASS MANAGEMENT

Digital bass management can be a confusing subject! A 5.1 or 7.1 soundtrack has several discrete speaker channels, and also a Low Frequency Effects (aka LFE or ‘.1’) channel. The goal of digital bass management is to ensure that all of the bass present in the speaker channels and in the LFE channel is properly managed, so the speakers and subwoofer perform optimally. This generally requires directing the LFE channel to the subwoofer, and also redirecting the bass present in each speaker channel to the subwoofer.

Our Sound Experts can assist you with setting up your subwoofer and running auto-set-up in your A/V receiver. We’ll advise you on the best digital bass management settings for your particular speakers and subwoofer, so the entire system performs optimally and sounds great.

The speaker size setting in the A/V receiver can be confusing or misleading, because the speaker size settings are often labeled ‘Large’ or ‘Small’, and in reality, these settings often have little to do with the actual physical size of the loudspeaker itself.

A Large setting means that channel will receive a full-range (aka full-band) signal from the A/V receiver and none of the bass present in that channel will be redirected to the subwoofer. With the exception of certain bass-capable tower speakers (refer to the next FAQ below for details), a Large setting for a loudspeaker channel is not recommended since it might overload the speaker and damage the drivers, and it also can consume additional power from the A/V receiver amplifier, thus reducing dynamic headroom.

A Small setting means the bass in that channel will be redirected to the subwoofer below the crossover frequency selected/specified for that channel in the A/V receiver. Again with the possible exception of certain bass-capable tower speakers, a Small setting is recommended since it removes the deep bass requirements from the loudspeaker, and frees up power in the A/V receiver amplifier, thus improving system dynamics.

The best speaker/subwoofer crossover frequency for each speaker channel varies with the bass extension and output capabilities of the specific loudspeaker. Sometimes the auto-set-up system in the AV receiver will select a non-optimal crossover setting for a given loudspeaker channel. The below guideline will allow you to double-check the selected crossover frequency. If you are still unsure you can always contact the Sound Experts at SVS Customer Service for assistance. Our Merlin loudspeaker/subwoofer matching tool will also provide the recommended speaker/subwoofer crossover frequency for your model speaker.

Typical Recommended Speaker/Subwoofer Crossover Settings:

Very small or ‘satellite’ loudspeakers: 120-150 Hz.
Small to mid-size center channels, surrounds and bookshelf loudspeakers: 80-100 Hz.
Larger center channels, surrounds and bookshelf monitors: 60-80 Hz.
Tower speakers with smaller (i.e., 4”-6”) woofers: 60 Hz.
Tower speakers with larger (i.e., 8”-10”) woofers: 40 Hz or Large/Full-Band (refer to the below FAQ for more details on the best settings for bass-capable tower speakers).

I have large bass-capable tower speakers with multiple 8” or 10” woofers. What are the best AV receiver bass management settings for this type of speaker?

If the A/V receiver can only assign one (1) global speaker/subwoofer crossover frequency for all speaker channels, then bass-capable tower speakers should always be set to Large (i.e., full-range / full-band). The LFE+Mains (aka Double Bass or Plus) subwoofer option should be avoided with this type of A/V receiver, as it will often result in too much overlap between the mains and the subwoofer.

If the A/V receiver has the capability to assign an individual crossover frequency to each speaker channel, there are three (3) bass management options for bass-capable tower speakers:

Option 1: Set the mains to Small (i.e., not full-range / full-band) with a 40 Hz speaker/subwoofer crossover. This will allow the tower to play quite deep and takes good advantage of its extension and output capabilities while routing only the deepest front channel bass to the subwoofer. This is an excellent choice for most floor standing speakers, many of which naturally roll-off below 40 Hz.
Option 2: Set the mains to Large (i.e., full-range / full-band) and the subwoofer mode to LFE. This will send a full-range signal to the tower speakers and will not re-route any front-channel bass to the subwoofer. This option should only be used if the tower speakers are truly full-range with usable extension and output into the mid-low 20 Hz range.
Option 3: Set the mains to Large (i.e., full-range / full-band), set the subwoofer mode to LFE+Mains, and set the mains ‘crossover’ (which in this case is actually a low pass filter) to 40 Hz. This bass management option will send a full-range signal to the tower speakers and will also send a duplicate front-channel signal to the subwoofer, but only <40 Hz. This option can be an excellent choice if the tower speakers have usable extension and output into the mid-low 30 Hz range.

SVS LOUDSPEAKERS

The location of the front loudspeakers relative to nearby boundaries will excite various room modes (a complex pattern of standing waves with associated peaks and nulls), which will affect the bass response of the loudspeakers. Generally, placing the loudspeakers closer to room boundaries (particularly corners) will increase the bass response. Conversely, moving the loudspeakers away from boundaries and corners will reduce the bass response. Due to the complex interaction of the loudspeakers with nearby boundaries/corners and your listening position, significant changes to the bass response can occur with very small changes in either loudspeaker location or listening position, so experimentation with both placement and listening position is recommended to obtain optimal results.

A smaller tightly-enclosed listening room with a high amount of ‘room gain’ (a naturally rising low-end response) may cause an excessively strong bass response from the Ultra Tower model, regardless of its placement location in the room. If this occurs, insert the included foam port plugs into the port opening of each Ultra Tower. To obtain a good seal, insert the foam port plug slightly below flush of the port flare.

Inserting the foam port plug creates a low-Q sealed acoustic alignment, and results in an earlier roll-off of the bass response. This will often be a better complement to the acoustics of a smaller tightly-enclosed listening environment, resulting in a more balanced and natural-sounding bass response.

The amount of exposed glass, drywall and bare flooring in the room will increase the amount of reflected sound and exacerbate problems like slap echo and ringing. Conversely, furnishings like carpeting, drapes and upholstered furniture will reduce the amount of reflected sound in the room.

The ratio of direct-to-reflected sound and the decay characteristics of the listening environment will have a large influence on the ultimate sound quality of any loudspeaker system. Dedicated room treatments like absorbers, diffusers and bass traps can greatly improve the sound quality of any listening environment and are encouraged to extract the absolute best performance from any high-end loudspeaker system.

For the ultimate in flexibility, the Ultra Surround can operate in three different surround sound modes:

  • Duet mode – each set of drivers receives a discrete signal.
  • Bipole – both sets of drivers in phase.
  • Dipole mode – both sets of drivers out of phase.

Duet mode is a unique configuration which allows a single Ultra Surround speaker to be used as two independent speakers. This means you can use just two (2) Ultra Surround speakers, and still have four (4) discrete side/rear surround channels for a true 7.1 surround setup. Duet mode is recommended for all home theater systems which have a 7.1 A/V receiver and use one (1) pair of surround speakers.

In bipole mode, both sets of speakers are in phase, which provides a more localized and directional surround sound effect. Bipole mode is recommended for home theater systems which have a 7.1 A/V receiver and use separate side surround speakers and rear surround speakers.

In dipole mode, both sets of speakers are out of phase, which provides a more diffuse and non-directional surround sound effect. Dipole mode is recommended for home theater systems which have a legacy 5.1 A/V receiver and use one (1) pair of surround speakers which are mounted directly to the sides of the listening position.

Do I need an external amplifier to power the SVS Ultra loudspeakers?

The SVS Ultra loudspeakers have excellent sensitivity and are easy to drive with any quality A/V receiver. If the Ultra loudspeakers are being placed in a large listening environment and will be driven to high playback levels, and external amplifier will help avoid amplifier clipping and maintain optimal system dynamics.

The Ultra Tower is a true full-range loudspeaker with usable deep extension to 28 Hz. With the possible exception of acoustic pipe organ music (which can extend to 16 Hz), the Ultra Tower does not require a subwoofer for 2 channel source material.

In home theater systems using the Ultra Tower, a subwoofer is still recommended to handle the redirected bass from the other speaker channels, and the LFE (.1) channel. Refer to the Digital Bass Management section of our FAQ page for more details.

Proper placement of the front left/right speakers is essential to achieve the smoothest frequency response, optimal stereo imaging and the most spacious, three-dimensional soundstage.

Stereo imaging and soundstage are affected by loudspeaker location and the listening position, relative to each other and room boundaries. Moving the loudspeakers away from room boundaries will tend to improve stereo imaging and spaciousness by attenuating and delaying boundary reflections, thus optimizing direct sound and helping to preserve spatial information in the recording.

SVS recommends starting with the front loudspeakers located 30-degrees to the left and right (i.e., a 60-degree total window) of the listening position. Toeing-in the loudspeakers 5-10 degrees can often improve imaging, however, this is also a function of the distance from nearby boundaries and the ratio of direct-to-reflected sound, so experimentation with toe-in is recommended to obtain optimal results.

CARING FOR PIANO GLOSS FINISHES

Below are the best practices for piano gloss maintenance and care:

  • Dry dust only with a microfiber duster.
  • Never dry wipe the surface, as this will embed surface contaminants into the finish and cause micro-scratches and scuffs.
  • If cleaning is required, use a microfiber duster first, and then follow with a lightly damp microfiber cloth. Wipe only in straight, long-strokes in one direction.
  • Micro-scratches and scuffs may be gently removed (after dry dusting and damp wiping) with a high-end automotive polish which is rated as safe for clearcoats and is specifically designed to remove micro-scratches. Apply the polish gently, and avoid polishing on edges and corners.
