A masterpiece of sound and design, the Synergy Series Sub-10 shakes things up with its rock-solid performances. Its extraordinary power adds a dose of "reality" to movie explosions and other special effects, as well as reveals commonly elusive lower musical tones.

Summary: If you shop around you can get the SUB-12 for the same price
Comment: Though this may be a better sub than what you get from home-theater-in-a-box systems, and it's better than most of the Polk and Infinity subs available, if you are a good shopper you can get the SUB-12 for the same price as this one, and it's a MUCH better sub. Or, you can find the internet-direct companies that have as good or better performance (and amazing customer service) for the same price: like Elemental Designs, HSU, SVS, AV123.

Summary: DA BOMB!
Comment: First movie I watched after installing this sub was Star Wars IV. This sub has amazingly powerful lows, when the Death Star in the movie blew up Alderaan I could literally FEEL the impact, my walls shook, my TV shook, a CD on a shelf 18 feet from the sub fell over and it nearly caused my lava lamp to rattle off its shelf.
This baby has POWER.
I highly recommend you set expensive items off high places till you adjust this sub's bass output to correctally match your speakers. SERIOUSLY :)
I paired mine with the Klipsch Quintet SL speaker set, makes a great package.

Summary: Subwoofer
Comment: This is a tremdous improvement over bass speakers I've owned in the past. Deeper, fuller and not boomy at all. You actually feel the sound much like listening to a large pipe organ. It's the best I've ever owned.

Summary: A Real Sub!
Comment: I recently replaced a Polk Audio PSW-12 with the Synergy. This is an amazing upgrade. It mixes well with the Polk RTi-8 Fronts, and CSi-3 Center, R15 surround and Infinity Primus 250 Back Surround. All of these speakers are powered by an Onkyo 803.
The previous sub had good bass response, but was very directional. What I mean by that is I could hear the bass coming from the sub. It did not fill the room. The Synergy fills the room, and actually makes the bass sound like it is coming from the individual speakers. If you increase the gain, it will shake the house.
Installation was very simple. I used the LFE connection, and plugged it in to power. It also has an automatic power save mode, and a light on the front to let you know what mode it is in. Over all, a great value!
