mighty subs

"Good SW...Love it...plenty of power...i ran my in home movie theater without a sub and now I see what I was missing this thing shakes the house during movie night and music videos sound amazing"

"plenty of power"

"Not bad...Woo hoo...So the Sony is slightly more powerful....I do not like listening much above 90 dB's, but this sub can easily jog along with my Vizio soundbar to very clear and undistorted hearing-damage levels I believe are above 100 dB's."

"So the Sony is slightly more powerful."

"Love it...Love it....Bass is POWERFUL...But in this one, there's no need for that, I just simply love it... I LOVE IT... Even my wife, who doesn't care about this and prefers the audio devices to be hidden so they can't b seen, only heard, says that is very beautiful... it is even prettier than the sound bar... So my point (sorry about the excitement), I am not sacrificing anything and I am having all the power, pristine performance, and beauty... all in one package."

"5 stars...love it...Bass is deep and powerful...I played around with turning on and off the sub while playing a song (in the advanced settings menu), and without the sub, the sound sounded weak and hallow compared to the umphh the sub gave."

"Bass is deep and powerful"

"Love it...5 stars...Excellent Buy sometimes too powerful for an apartment...I played around with turning on and off the sub while playing a song (in the advanced settings menu), and without the sub, the sound sounded weak and hallow compared to the umphh the sub gave."

"Excellent Buy sometimes too powerful for an apartment"

"Love it...Love it!...Very powerful yet small....I would highly recommend this sub for $399, personally I think they could get away with $499 since it offers premium bass definition in such a industry leading small size."

"Very powerful yet small."

"Love it...Good Sub...Powerful and Full Sound...I love the compact size and the fact it delivers such a good bass response but I dont like the fact that you pretty much have to turn the bass knob a bit pass halfway to get the boom your looking for and since you have to do so the you can only turn your receiver up so much otherwise the sub cant handle the power and shuts off and my receiver is only 700 watts the sub is 650 watts max and I believe 300 rms"

"Powerful and Full Sound"

"Worth it...Best sub...Compact, powerful, excellent response....I chose the Martin Logan, and it sounds great, wish it had a bit more power, but I suppose I could have spent more to get one with more power."

"Compact, powerful, excellent response."

"Good Sub...LOVE IT!!...Great compact sub with big power..., I first bought the supercube 2000 , but I own the supertowers 8060 model with included subs and to my ears sounded a little weak for my particular setup, not the case with the 4000, I have them connected to a denon 4311 ci , havent calibrated it yet, but all I can say is wow without calibrate them , the sub really delivers, grat for music, superb with movies, you wont regret getting one of these."

"Great compact sub with big power"

"Great sub...Best Bass!!...Big and powerful...I use my system for high quality movie watching so I have this paired with a 112SW sub and 7 other klipsch speakers ranging from 4 tower speakers, two bookshelf speakers and a nice center speaker."

"Big and powerful"

"Love it....Good sub...Great Powered Sub Woofer....Even at full price I would consider these Polk subs to be a great deal... I was so happy with this subwoofer that I even purchased a second one, only becuse my main speakers are extremely small and can not produce bass at all...."

"Great Powered Sub Woofer."

"Love it...- nice....The sound quality clear and powerful....Setting it up was also quick (a matter of minutes) and easy - all that was needed was the Bose app and connection to the WiFi - I was able to pair it with my Bose Sound-Bar 500 which I also paired with Alexa - so I was able to stream music through both."

"The sound quality clear and powerful."

"Love it...all good...Lot of Power...As for the sub I liked it so much that I ended up buying a second one for my system."

"Lot of Power"

"love it...Love it....It has a lot of power; however, I noticed that it rattles along my woodfloors when it hits very deep lows....I understand why people like it and I can admit it's a quality product, but at this price point I expect 5 star product and this isn't quite it."
