Fi Technical

I wanted to know if the RE SX recones that fi have on the site will fit and work in the HC motor as well. I tried to get a hold of Nick at FI through several emails to find out but no reply , so after a couple of weeks I went ahead an ordered the RE SX 15 d2 as there was no recones for the HC on the site . any help would be appreciated Thanks in advance.

Hello I have a jeep srt8 with two rockford fosgate 1500.1 bcd's and four rockford p3 15s in a custom box tuned to 35 hertz. I want louder now. I've been hearing alot about the fi subs. I wanna keep my amps but get four fighteens that will do great with my amps. Both amps comined will do 3900 watts rms. I've been looming at the fi bl line. They are rated at 1000 watts rms 2000 peak. So if I had four Of them they would be 4000 watts rms , I would only be shorting them 100 watts. My question is can these amps slam the bl pretty hard and can I use my same enclosures I have now with 12 cubic ft and , 6.1 per chamber for two subs on each side and tuned to 35 hz. Basically each…

Simply as the title has stated. Scott do you have enough parts to build another X 12 for me? or a recone for my current sub? or possibly just a dustcap and some tensil so i could fix the sub myself? What would be the cost of these different things if they are even available? Thankss!

Searched all over, and can't find the Le (inductance) spec number for the Q15 subs. Anyone know this spec?

What is the cabinet size for a Fi SSD 10 high QTS version

Hello, I was wondering if someone would be kind enough to assist me with my first enclosure build. I created an enclosure in Torres that seems to meet my needs, but I am not quite sure if there is enough port area for these subwoofers. Being a long time lurker, I know the people here are quite knowledgeable, so I figured I would throw it out there to see if it will work, or if it needs to be changed up. Here is the screenshot for what I have worked up so far in Torres: Does that seem good enough for port area? This is going in the trunk of a 2004 Toyota Corolla. The dimensions for height and width are the max that I can get away with for front firing subs. If …
