I just got an SVS 20-39 PC+ a few weeks ago and that thing can really drop some low notes. It might be overkill if you don't listen to music with a heavy bottom end, like rock or pipe organs etc. The other thing that really impressed me with the SVS is that it has a Parametric Equilizer (PEQ) on the amp to take out any bumps in the frequency response caused by your room. It really is an incredible sub, and while I have the model just above the PCi, I expect that the PCi will be able to give you more than you bargained for.

You could always try going to a local AV store or a Best Buy with a Magnolia Theater as well and listen to them before you buy. Paradigm and Definitive Technologies are great as well. to read some reviews go to www.soundandvisionmag.com, they have a review section you can read.

SVS will crush all. I highly endorse an SVS sub. I have the baby of the bunch. The 10" 300w sub, and this thing is a beast. It made my polk audio sub sound like a 6 1/2" woofer. If you get a 12", glue down all you glass, and its worth a look. The cabinets are beautiful, and they get a little pricey, but for $600, you may be able to come out good.

Only if you're into rap or hip-hop. I find that subwoofers, especially the bigger ones, generally detract from true "musical" bass.

Here are some key points:

# 5 Subwoofers care what they play

Your subwoofer driver does not have a conscience, and it does not perform better with one type of music over another. It’s just a driver. Good subwoofer systems will play all types of music or movie material very well. A bad subwoofer system may have a null or peak in the frequency response that may benefit some material over others but essentially this non-linear behavior is not ideal. It is true that movies have lower frequency content and perhaps more dynamic bass than music, especially with the recent compressed CD’s of the last 10 or so years, but a good system can be used for movies and music alike if it is indeed a “good” system.

It is also true that it tends to be more important to emphasize subsonic frequencies in the home theater environment versus the music environment where there is simply less emphasis on subsonic inaudible material. As a tradeoff, you can align a system to be more efficient above 30Hz or so. This trade off reduces the bandwidth but increases the SPL. Careful consideration should be taken to insure linear response is still maintained. It is very easy to have peaky bass with low Q drivers in high tuned ported systems. This is approaching the concept of basic SPL vehicles which use low Q, highly sensitive drivers tuned very high for very narrow but ferociously peaky response. Such systems are not very ideal for listing to music material of any kind. If you want your system louder, then it is better to add a second driver, more volume and more amplification, rather than tuning higher. It is important to understand that getting more SPL without compromise is never very cheap!

# 8 Smaller drivers sound better than bigger drivers

One of the biggest myths about woofers is that 8’s and 10’s are “tighter” and “cleaner” than 15’s or 18’s. Nothing is further from the truth. What tends to happen is that the smaller drivers have lower Q’s because manufactures tend to put large cones on smaller motors to increase SPL and sensitivity but not BL product. Well unless the motor can compensate for the extra mass it has to push, then the Qts will not be the same as the smaller drivers and ultimately the driver may not be suited for the same kinds of alignments and could ring too much and compromise the perceived sound quality. Having said that, high Qts drivers are not any less “tight” or “musical” than well dampened drivers, it’s just they require larger boxes and less internal pressure to prevent ringing. Ultimately there becomes a point where a driver really should be used in an infinite baffle where its actual Qts and Fs becomes the system Qtc and Fc. As enclosure volume decreases, Qtc increases and it will take a driver with a low Qts to make for an average Q system. So in conclusion, the only reason to use a smaller bass driver is for space, weight and potentially power considerations, but likewise, it is inappropriate to try and fit a larger driver into a space smaller than it is ideal for.

Thanks! Much appreciated. My local shop is very helpful, so hopefully they can help me find the best sub for my system.

You're welcome.

The guys at SVS are also very helpful and don't mind spending time through e-mails and phone calls to assist you by answering any questions you have and recommending subs based on your system.

I have never met anyone that felt they were trying to upsell them on a bigger sub. Most times they recommend something lower than what most people think they might need.

(And yes, either of those subs from SVS or Hsu will be a good addition to a musical set-up)
