FS: Fi Sp4 15 D2 $425

Recommended Posts

I have for sale a used Fi Sp4 15". It has the cooling option, and space spider as well. It is a d2 and with a carbon cap. I ordered this sub directly from Fi on November 15, 2013 and recieved it around early December.


Mechcanically: 10/10


Physically: 9/10


I would prefer local pick up only, I am willing to drive any where within an hour distance from where I live if serious. The box does come with the sub also. The subwoofer has been powered by an aq2200, ct2500.1, and a ct1400.1 without any issues.


The price is somewhat flexible.

      Hey guys manzkea back at it again! Lol. Finally got some equipment in. Excited to finally get this project I’ve had in mind for a while rolling . Gonna attempt a blow through in my single cab 2001 ford ranger long bed. Gonna make pods for the doors to house the 6.5s and replace the stock one with a 6.5 or if possible an 8” driver. All powered off the ssa ic150.4.  As for subs I’ll be using a 15” sp4 v2 I got from a friend for a deal. A taramps 5k will be used to push it.
      Unfortunately the evil mids I wanted was unavailable in 4ohms. So I went with these prvs.
      Well I’ll I’ll be updating this as I get it going. Possibly next week or so, really busy with work at the moment. Well here’s a pic of some goodies the mail man dropped off.  Cheee. 
       Btw got something extra special in those two ssa looking boxes behind the ranger gear. But that’s on the back burner at the moment.

      1. Product: 2 Fi SP4 18s with Carbon Fiber Dust Caps
      2. Specs: Both are dual 1 ohm (0.7 ohm)
      3. Description/Condition: Ran them for a little under a year on low power (Audioque 2200). Magnets have some scratches but the surrounds, baskets, spiders, and coils are in excellent condition. Does not include the original gaskets. A couple of the pictures are next to a 10" Kicker "Competition" (lol) for size comparison.
      I threw out the original boxes some time ago, but Fi was nice enough to send me two brand new boxes to ship them in. So these will ship in original Fi packaging.
      7/10 Cosmetically
      10/10 Mechanically
      4. Price: Asking $900 SHIPPED OBO for the pair. Because they are dual 1 ohm, I would like to keep them as a pair. NO TRADES, just trying to get rid of all my stuff.
      I'm located in Huntsville, AL 35810. Would be willing to drive to meet someone within reason.
      5. Pictures:
