I have owned a Fi BL series 10" subwoofer for almost a year now, roughly. I would like to do a simple review on it, if you guys are interested in my input....
This sub cost me $350.00 shipped to my door. It is rated at 1000wrms but with the extra cooling components and flat wind coil the company claims that the sub can handle 2-300 more watts,
I am here to tell you that I run this sub off of my DD M3a which is putting out roughly 2kwrms estimated, The box i have is 1.2cuft internal ported to 35hz with a 4in dia round port, (note: at full tilt on some frequencies i get a little port noise, meaning that 5in dia port would be better)... with this setup i can play my amp just in to clipping slightly and the sub shows no signs of stressing at all, i mean that this sub handles it with ease. So 2kwatts is no problem for this sub and it gets quite loud doing it. i have played this driver for 20 minutes at a time attempting full tilt unclipped and i dont really get any heat from the dust cap.
My review of this sub it that it is a sweet beast of a sub, capable of easily 2k clean watts....... great sub, damn good sub, I recommend this sub, there may be better for cheaper but mine is rock solid and im pleased with it.... impressed to say the least.
