Sub-12 HG

Klipsch Sub-12 HG Subwoofer

Great sound begins with great bottom end. The Klipsch Sub-12 HG subwoofer delivers the two lowest octaves of the ten humans can hear, intensifying your listening and viewing experiences. The down-firing driver and rear-firing port produces increased bass response with low distortion, filling the room with warm, rich bass you feel almost as much as you hear.

Sub-12 HG

The Sub-12 HG gets its intensity from a 12-inch, down-firing driver coupled to a highly efficient BASH amplifier that creates 300 watts of continuous power and 650 watts of dynamic power.

The subwoofer's built-in, steep-slope low-pass crossover is continuously adjustable from 40 to 120Hz. A phase control facilitates acoustical integration of the subwoofer with the other speakers in the system. An "auto power" feature enables the subwoofer to turn itself on and off automatically, based on the presence or absence of an audio signal. A blue/red dual color LED display on the front of the subwoofer indicates whether the unit is on or in standby mode.


Sub-12 HG

In addition to its ability to play louder and go deeper than anything else in its class, the Sub-12 HG features an industrial design that is refined and aggressive. Available in a high gloss black finish with titanium accents, this extraordinary subwoofer will fit into your décor.

Because it wraps technical superiority and eye-catching cosmetics into one affordable package, the Sub-12 HG perfectly anchors a home theater or two-channel system.

About a week ago, I upgraded to the Klipsch Sub-12 from a lower powered 10" sub to complete the 7.1 home theater set up in my 12ft by 19ft basement room. I watch a lot of action movies and concerts on Blu-Ray/DVD. I highly recommend this subwoofer if you like to feel the deep bass and to shake the house. I located the sub at the front left corner of the room (about 10" away from the walls). This Klipsch seems to play noticeably deeper and louder (with power to spare) than the sub that I replaced. The sound from the subwoofer is not directional. Its sound just fills the room.

One small negative (easily fixed) is the small blue LED light on the lower front face of the subwoofer cabinet. The light shows that the sub is ON and operating. In my dark room, the LED is too bright. My solution was to simply put a small piece of black electrical tape over the light to hide it. The tape blends in with the cabinet and is not noticeable.

Again, I highly recommend this subwoofer for a surround sound home theater room with a size comparable to my room. Set up was simple and product quality seems to be excellent.

When I bough this subwoofer I was a bit skeptical. I have been researching for quite a while and narrowed my choices between this Klipsch Sub-12 and a Polk Audio PSW-505. I have been reading all the reviews that praised the sound of the Klipsch for under "$500" and the sort, but said that there are better sounding subwoofers out there in much higher price ranges. While the Polk PSW-505 seems like a very comparable subwoofer based on specs and price alone, I decided to go with the Klipsch because of the down-firing design. After opening, installing and properly setting up this sub, I was completely blown away that such sound can come from a home theater subwoofer. The power is more than anyone would ever need to listen to movies or even music, and the sound itself can hit so low that your whole house will be shaking. I dare say that for almost any budget, this subwoofer will sound amazing if paired up with the right receiver and speakers. Movies and music sound incredible, but even watching tv is a completely different experience with this subwoofer. The size is a bit on the large side, so if you want a small, unintrusive speaker that delivers just enough power, there are much smaller subwoofers out there. But If you have the space, and crave serious power, you surely will not be disappointed.

Ok... I'm going to try to make this quick. I've owned a Klipsch KW12 for 8 years and have been satisfied. Recently, I upgraded my entire system and when it came to adding a new sub... I looked for something else (I was not a loyal customer). Therefore... I reviewed and searched for months... eventually purchased a Velodyne Optimum 12 (Over $1400). Needless to say... I sent it back because it was barely better than my old Klipsch. So then I purchased a SVSound NSD unit based on reviews... and once again... I was not satisfied... so I sent it back. Finally, I purchased this unit (Klipsch Sub-12HG Synergy), and I'm extremely happy. The sound is better than the much more expensive units that I tried. Tight and deep. Not not mention... it blends in better than other subs.

Seriously, quit looking around. I know... its hard to believe that you can get a killer sub for only $299, but its true. This is a fantastic sub. Now I'm using this along with my old KW12 and I'm in heaven.

I've had this sub for almost a year now. I like to wait a bit before I post a review to make sure the item works the way it's supposed to. In one word, "Powerful." If you use a good source, this sub will sound fantastic. If you don't set it up correctly, it will tend to sound muddy. Overall I have been extremely satisfied and might buy another one to have a 2-sub set-up. For the price you can't beat it.

I owned the original Klipsch Sub-12 (same model as Sub-12HG except minor cosmetics) and gave it to a friend a couple years ago. I've regretted doing that ever since and have been on the look-out for a powered sub with comparable quality at a competitive price. Needless to say, I haven't had much luck... until the Sub-12HG went on sale for $250!!! You can't find ANYTHING comparable for that price, or even around $300. I'm totally stoked and am going to love every minute I have this turned on. Perfect for music, movies, etc. You can control the amount of power the amp delivers to the sub (gain) and the frequency that is allowed to pass through the built in cross-over (adjustable from 40 to 120Hz). The auto-power switch is also a nice feature since you don't have to constantly hassle with turning off the sub when you are done.
All in all, I couldn't be happier with the quality of another sub in this price range... this is really a $500 sub and that's not MSRP crap! To top it all off, Klipsch offers a 5-year warranty on the sub, 2-year warranty on the BASH amplifier.

Rumbles my windows, doors, and cabinets. I am running this subwoofer with Klipsch Quintet SL 5.1 with 2 additional Klipsch Surround speakers to create a 7.1 using an Onkyo NR616. I have not had a surround sound system before, but I know this subwoofer puts out a lot of power and oomph. It isn't just bass and supportive sound that you can hear, it's bass you can feel. I tried a U-571 scene (when the depth charges are exploding all around) and the subwoofer handled it like a champ. Explosions were crisp but also hit you in the gut.

Great deep bass, easy setup, quality product.
