Hii Im in the UK where Fi has just landed. Im changing over from 2 x 12" Re Mx's in a boot install to 2 x 18" Fi BL's fully loaded in a wall. As no one really has Fi yet in the Uk just wondering if anyone can answer my questions ? 1. How do the subs play the lower octaves ? 2. What kind of bass do they produce ? (DD slammy, Re wobble etc) 3. What subs can they be compared to ? (so I can get a understanding of how they are) 4. The SQ of the sub. I've already placed my order but was curious about the aforementioned points. Im after an all out streetbasser and each sub will have a Trutech Hammer H-1 powering it. Thanks in advance.
