You are a reasonable person, and surely you realize that a potential buyer of this unit who comes here seeking an honest evaluation of its performance has the right to know that it is not going to perform as well as some subs that cost only a little more. It's great that many of you are so happy with yours. It is a good, reliable, affordable sub, and I've never said anything different form that. But it is NOT a "great" sub.
You act as though anyone who is dissatisfied with its performance is an amateur and that our sound system "was not setup properly". Believe me, I tried very hard for months to make it reproduce two simple notes in several pieces of music that I listen to frequently. They just were not there, and it was obvious that they were missing. A different sub in the exact same location delivers them solidly.
So I will repeat myself... sometimes it is not the room, and it is not the listener, it is the equipment. I am not the first person to experience displeasure with its performance on music. Some have come back into this forum after discovering this to express their honest opinion and have been chased out by the fanboys. A number of them have never returned, and at some point I will not return. But anyone who is interested in buying this sub and reads the thread from beginning to end will stumble upon mine and a number of other posts expressing some dissatisfaction. Otherwise, all they will read about is how it "shakes the walls" and such. And if that is all you care about, then fine. Frankly I expected more.
