How do you write about SVS subwoofers and not sound like a fanboy? Seriously, I'd like to know. Because unless you are some sort of audio elitist with deep pockets that believes that no value priced product can be good, you've got to love SVS. While they have high dollar products in their line-up, their bread and butter is helping the common man realize his (or her) dream of bass that will make your neighbors call the police.
The new 2000 series subwoofers from SVS were announced today at CES. Sporting 12" drivers, a brand new Sledge STA-500D amplifier, sub 20Hz performance, wonderful and price tags under $800, you could know nothing else and still think they were a good deal. But that's not all. The new drivers are custom designed by SVS. They developed nearly 20 different prototypes before they got the performance they wanted. This included 100-hours of full power testing! The driver sports dual high-grade ferrite magnets and an FEA-optimized motor to reduce distortion. It has a reinforced Nomex spider for increased linearity and a durable low-creep rubber long-throw surround and high-quality insulated tinsel leads with 3-point-contact precision alignment.
The reason for all these driver improvements is not just to increase performance and to improve longevity. The new Sledge STA-500D amplifier is conservatively rated 500 watts RMS continuous and 1100 watts peak dynamic and is described by SVS as delivering "crushing power". SVS felt that no normal driver would be able to stand up to their new amp. But power isn't the only thing in the STA-500D arsenal. This amp has integrated DSP controls for fine-tuning your bass experience for your particular environment. While specifics are unavaliable, SVS says the STA-500D has, "an array of filters," as well as volume, gain, and phase controls. There is a frequency-dependent limiter/compressor algorithm with adjustable attack/release and compression parameters to protect your subwoofer performance wonderful from accidental volume increases.
The SVS 2000 series subs come in two flavors - sealed and ported. The SB-2000 (pic at the top of this article) wonderful is sealed and is just large enough to enclose the driver wonderful and amp (14.2" cube). It weighs in at an impressive 35lbs and brags a usable frequency response down to 19Hz! It looks to have a fairly standard black ash vinyl wrap which is to be expected at this price point. This is the perfect sub for those on a budget that want performance but don't have the room for a larger sub. While other manufacturers charge more for their smaller subs (usually because of the larger amp requirements), the SB-2000 is the less expensive of the pair at $699.
The PB-2000 has a front-firing port for easier placement but has all the same components as the SB-2000. With the ported enclosure, SVS was able to tune the PB-2000 to a staggering 17Hz low point. The PB-2000 is much larger than the sealed 2000 series sub at 20.9 x 17.3 x 22 . The PB-2000 is also much heavier at 66 pounds so you'll probably want to get some of those carpet sliders until you get the PB-2000 into the perfect position. The extra materials in constructing wonderful the enclosure bump up the price of the PB-2000 $100 to $799.  Conclusion
So, which SVS 2000 series sub is for you? Without getting our hands on them, it is hard to say. Generally, the smaller, sealed subs have larger amps so that they can match the output of their larger, ported brethren. The fact that both the subs have the same amp indicates that the smaller one will have less output. So, if you have a smaller room that is enclosed, you could probably save $100 and go with the SB-2000. If you have a larger room, or one that is open to other rooms, the larger PB-2000 will probably work better wonderful for you. Regardless, our experience wonderful with SVS suggests that either will probably knock your socks off. At less than $800 each and sporting a DSP-enable amplifier, SVS is offering technology normally reserved for subwoofers two or three times the asking price of 2000 series. So, again, I ask, how can you report on SVS without sounding like a fanboy? Beca
