As long as you have the space, budget and amiable enough neighbours, we say go for it. Just be prepared to host movie nights from now on." What Hi-Fi?, 5 Stars "The new subwoofer sounds bigger and deeper than previous efforts from Q Acoustics, but it’s also more effortless in its delivery. The Q B12 integrates perfectly with the 3010i speakers, creating a balanced low frequency foundation. It’s also a very responsive design, revealing plenty of speed that ensures both music and movies sound equally as good." AVForums, Recommended
