*Swift's Rebuild* 3 SP4 18's, 12k Walled F250

Recommended Posts

Here's the model you asked for. The green is a classic super boom box. It gives you more bottom end but you just don't have enough room for it. I played around with several box sizes and tunings staying within your deminsions and I'd stick with the plan you had the PM's so you can adjust tuning as you play with the system. The red is the 19 cubic feet tuned to 31.5 hertz that was talked about in the PM's.

Thanks alot, I know my truck peaks pretty low so I'm sure that will have some effect also. Did port area change that graph much?

Ok looks like I am at 20cu ft. net tuned at 30.5, with 275in of port area. I think this will be fine. May not meter the loudest but should murder the lows, anybody find a good priced 5500 let me know.

So after looking at a Vent Mach calculator I am ending up with .040 - .052 depending on the power I run. From what I have read this looks like it will work good. I will post up some photos tonight of the enclosure being assembled hopefully.

I have to go get the all thread I will use for bracing. I also will probably be using some 2in hardwood dowel for the vertical bracing so I do not have to run all thread through the port, although that may be a perfectly fine option. I also will probably use solid brass terminals instead of regular zinc plated. I will use 12 posts (one for each coil) so re-wiring can be done without removing subs.

      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:

      12" Fi BTL UFO Dual 2 ohm
      Item(s) Description/Condition:
      -pie slug style Fi UFO motor
      -12" 12 spoke aluminum frame painted hammered gray
      -PSI recone rated for 3k RMS

      This sub has been nothing but great to me. Can't say enough about it. Sadly I have just sold my amp and made a bunch of space in my trunk for a lot more business. ( (2) 12"s )
      This 12" can do it all..handled my MMATS m3000.1 with ease, hit the lows, and was great for a daily woofer.
      Has always been on a good supporting electrical cast. I am pulling the sub tomorrow because I'll be pulling my amp as well. Can take more pictures for people with more interest then.
      Recone has a date of 9/xx/14 and actually didn't use it for about 4 weeks it was installed because I had to wait on a warranty claim on a battery.
      There is a bit of a glue splotch on the top plate, but no biggie, just CA. bottom of motor looks mint.
      Minimal chips in ferrite. Included is the motor boot and 12" gasket.
      Price:
      275$ plus shipping
      Shipping and Miscellaneous Item Information:
      Ask me for a shipping quote
      Will be using UPS.
      US 48 only.
