Checking out both subs. Seems to be exact opposite of each others. The mirage is very small...but had great reviews. I am wondering why I can't read the HCC review about it? According to Mirage it was HC subwoofer of the year with HCC. Anyway i am interested in people who have used or are using this sub. Second subwoofer I am looking at...is the ASw1000. It seems to be a huge monster sub. But comaparable to the REl 100. Only problem is that it 's troublesome to position. Can some here clarify this? What does it mean and what's the best position for teh sub.
