Page 2 SV Subwoofers Welcome. From the entire SVS team, congratulations on your purchase of the new standard in home theater and music bass! Your new subwoofer isn’t some generic, mass-produced box built some- place you can’t even find on a map. It’s built in our Ohio factory, by home audio enthusiasts... like you. Designed, tested and assembled by our crew, while using state of the art automation and materials, your SVS is without a doubt one of the best investments you’ll ever

Page 3 SV Subwoofers About your SVS Subwoofer Other subwoofers might look like them — but virtually none work like them. Not at this price. SVS’s are decidedly different, in how they are designed, produced, sold, and even in the exceptional customer service after the sale. No surprise then, you could have spent much more and still not come close to the value and performance our Powered Box lines provide. But what makes a subwoofer an SVS??? Quality parts, sane prices. You might b

Page 4 SV Subwoofers Setup, calibrating and integration What’s to know? Well, first of all, setting up an SV Subwoofer is pretty darn easy. There are a few key things to get right if you want to get the most out of your new equipment however. Unpacking. You’re probably eager to fire up your sub (we’re the same way), but take time to carefully unpack your sub. Set the box and other protective shipping materials aside; saving them in case you ever need to return the subwoofer for

Page 5 SV Subwoofers More Setup, calibrating and integration If you are running a pair of SV Subwoofers (Fig. 2), you will need to use a standard “Y” cable adapter (d.) The best adaptor to use for this task has one male RCA connection and two female RCA outputs. (Radio Shack ® stocks them.) From the “Y” cable you can run a standard 75 Ohm RCA to RCA signal cable (e.) to each sub, thus “splitting” the Low Frequency Effects (LFE) and other bass signals from your receiver and effectivel

We don’t mean “is your subwoofer amplifier on?” (that’ll be important later too) but rather, is your receiver sending a bass sig- nal to your sub amp? This can only happen if you say “Yes” (or “ON”) in the “Subwoofer” selection during the all-important setup menu of any typical Dolby Digital/DTS capable receiver. If you have a choice of “crossover points” for

Page 7 SV Subwoofers But what’s “too high”?? Tastes vary, and so do movie soundtracks, but your SVS is capable of tremendous levels of low distortion, low frequency bass — far more than most subs. Take advantage of this, especially if you like action movies with lots of “.1” channel (LFE) action, and give the sub a bit more “bump” during calibration (also known as running the sub “hot”). Keep in mind too that the human ear is relatively in- sensitive to low frequencies. This, coupled

But don’t despair if you don’t hear much differ- ence with changes to the phase knob — the effect of bass cancellation will vary by volume and frequency in your room, and no single setting is likely to ever be “perfect”. One simple technique to optimize phase is to find a nice “bassy” loop (such as the menu of the “Godzilla” DVD) and measure

Page 9 SV Subwoofers Parametric Equalizer (PB12-Ultra and select PB12-Plus subs only). Important enough and challenging enough, this feature gets its own section! “PEQ” al- lows you to tame a “peak” in your room’s response. Peaks are quite common, especially in large rooms or ones where your sub is far from your listening position. NOTE: A Sound Pressure Level meter is a must for proper use of the PEQ, so get one before you tackle this control. TO DISABLE THIS CONTROL: Set the “LEVEL”

Other good examples for test discs are Avia’s Guide to Home Theater . When measuring the room’s response use a minimum resolution of 5Hz. Figure 3 on the previous page shows a theoretical illustration of a room’s response. Before you plot your results however, it’s important to note the Radio Shack sound meter is not totally "linear

SV Subwoofers Page 11 The LEVEL control is the amount of attenuation on the signal located at the center frequency. MIN is equal to 0dB and MAX is equal to -12dB “cut”. Each hash mark reduces the Center Point in question by 1.5dB. The “FREQ” control (short for frequency) is the adjustment for the center point of the cut and should target the highest peak frequency in the room’s response. Each hash mark for this control moves the center frequency for the desired cut 5Hz, within a ran

SV Subwoofers Page 12 Subsonic Filter and Port Tuning Your new SVS subwoofer not only comes with our “Tri-Power” port flares, but custom port plugs and variable subsonic filter which allow your sub to be “tuned” to even lower frequencies than its stock configuration. For most people and most rooms, your SVS is already configured for the best blend of extension (how deep/low your sub goes) and output (how loud it gets at a variety of bass frequencies). However, we know that bass i
