Pros: cost to benefit ratio is high, sub blends well, great lows, easy to control the output, not boomy or underpowered like many $200-300 subs

Cons: larger than many 10" powered subs, BUT, that box size is one of the reasons it goes as low as it does.

Overall Review: excellent value for the $$ at present you can net shop and get the klipsch synergy 10 aka sub10 and the jbl es 10 for similar money. without having heard any of the 3 and even more important, heard them in a similar room; i chose the energy based on it's ability to go lower than the other two serious contenders.

Pros: This speaker is great. I've been told from audiophiles that this is one of the better subs, and for the price it's practically the best bang for your buck. This sub doesn't start doing much under 10 o clock on the dial, but once its turned to at least 12, it starts working magic. The sound is very deep and clean and is perfect with music.

Cons: In a big room or a room with an open end this sub starts getting washed out. You have to turn the bass almost to max before it does its job. Remember this is a "10 so don't expect too much if your putting this in a big room. Also there's a light in the front that glows a bright blue when the sub is on. I'm not a fan of it, but i'm not deducting an egg for something like that.

Overall Review: 5 eggs for such a great sub!

Pros: A definite upgrade from my polk audio psw10 that I previously had and this sub blows it away. Very clean sound at any volume and delivers awesome lows. I would have to say listening to music and watching movies has never sounded better. It really transformed my home theater completely. Highly recommended!

Cons: None.

Pros: Powerful and tight, these make good general use subwoofers. They hit deep, though they are clearly more efficient at some tones, making them seem louder around 45hz.

Cons: The LED on the front is bright (electrical tape = applied). The feet could be a little better insulated, but I've always found that to be the case with subs.

Overall Review: I have a 15x15 living room that's open on the right side, and use two subs ... one under each main. I'm not sure if just one of these would be able to keep up with my system -- at the very least it would be driven extremely hard. I bought these for $200 each and am very happy, though. They produce clean, never boomy sound, and paired can absolutely shake my house. I love the front-mounted gain control and adjustable phase knob. Normally your choice is 0/180 phase -- these let you fine tune between -180 and 180. In time, I plan to zone them in each specifically for the corners they are placed in. Those are both great features for this price point!

Pros: Price Build Quality Performance Works well with music and home theater 3 years old and still going strong!

Cons: Blue LED dies quickly (actually a plus for me)

Overall Review: I've had my s10.3 for over 3 years now. The Blue LED did go out within the first week but it was annoyiing and I was going to put electrical tape over it anyway. I was even sent another LED replacement but never installed it and don't where it is anymore. The subwoofer is awesome. I got mine from another vendor on clearance a few years back but it is worth the $250 that Newegg is charging right now. The s10.3 blends well with my speakers and is great with music and home theater. I would definitely take it over the smaller Energy M6 and M8 subwoofers which can't hit as low and fill a room as well as the s10.3. Don't let the LED issue bother you about the quality of the speaker components. Energy is a solid mfr of speakers from entry level to higher end product lines that cost over $2000 each. I have some of their other speakers in my collection too.

Pros: Picked up this sub for half retail...won't find a better buy. Yes there are better subs, but not at this price. Blends well with the rest of my Energy system... 2x RC50s, RCL, and 2xRC10s...makes a nice set....sounds fantastic.

Cons: Wish it were a 12" sub instead of a 10" for the size room I have and one that would dip a bit lower in frequency, but other than that, I'm very satisfied with it at the price paid.

Overall Review: As usual, Newegg delivered it FAST...free shipping...no damage. Outstanding service.

Pros: Sound Quality is amazing. Ive only had one week setup so I cant judge the reliability but the bass does not rattle or sound bad. It sounds amazings so far with my onkyo 709.

Cons: None at the moment but realise that the majority post cons about this sub because those who speak out are generally the ones that had a bad experience. A vast majority most likely really enjoy this sub and without flaws.

Pros: Low Price Smaller Size Powerful Amplifier Huge Sound

Cons: Neighbors, pets or drywall may not be as excited.

Overall Review: I recommend getting a pair of these to smooth out the 'hot' or 'cold' bass spots around the room.
