Summary: I bought this to replace a 15" Cerwin Vega and it outperforms the 15" sub even at the low frequencies. It should be noted there are not two subs in this box. There is One active sub woofer and Dual 10" Passive non-resonant Woven Fiberglass drivers. The digital display is great to adjust the sub with and it is quite compact. I would recommend this sub to any audiophile!
Summary: This unit "blends" with the music and movie soundtracks, rather than overwhelming them. Speaker appreciation is very personal, which is why it is so hard to defend or rebuke a speaker. All I can say is "wow"; I really like what I hear. I used the manual method of selecting speaker settings, instead of using "ARC II". I also did not use my AV receiver's automatic speaker setup, I did not like the result; to little Bass. I was lucky to purchase during a sale.
Summary: I searched high and low for the best sub that I could purchase for under 650.00 and through an abundance positive customer reviews, I decided on the Klipsch 311. I initially purchased this sub to use along side an existing Velodyne DPS-10 sub, but after using the Klipsch 311 over the weekend, I've removed the Velodyne sub from our audio system and am only using the Klipsch to provide the bottom for my Polk monitor 40 bookshelf speakers and CS-10 center channel.
Summary: Worked flawlessly with e Klipsch wireless set-up. Speaker sound is great but needs to used with a well balanced system from the get-go. I tried to add a little depth to huge family/kitchen/ eating room combo with some smallish but only okay ceiling speakers. The sound is fine some of the time but the TV can switch mix up the audio levels and frequencies (e.g. when commercials come on or a scene change) making an uncomfortable sound with an overwhelming bass effect.
Excerpt: Oh my goodness! WOWWWW!!! This is ridiculous! I haven't heard bass like this in a long time. I get goosebumps every time I listen to music with this sub. This company has gone above and beyond with the design and sound quality that comes out of this subwoofer. You will be blown away...no doubt. I will stand by this sub and say that it is super-duper powerful...more powerful than any other theater sub I have heard. SPL levels are just crazy!
Pros: Attractive Design, Easy to Mount, Easy To Set Up, Good Power Output, Great Sound Quality
Summary: I purchased two of these and for my use I have not been disappointed. I have tried with just 1 on and I was a little disappointed, but I knew one was not enough for my room size so that was expected. My room is approximately 5000 cubic feet. Even before purchasing these I had the intentions of adding a larger sub later on, perhaps a THT if I have the time or a 12/15". For likes: I like how small they are. For the size they are very effective.
Cons: Открытые пассивные боковые излучатели, ничем не прикрытые, поэтому, теоретически их можно чем-нибудь задеть. еле слышный шум системы охлаждения усилителя. Завышенная цена, покупал в Америке в 3 раза дешевле.
