These drop-in kits are for Sundown Z v.5 subwoofers.

Due to the length of the former, our current 8-layer coils cannot be used for 18″ recones.

Drop-in kits DO NOT include shims or glue.


If you are not 100% sure about re-coning, please ask us or send your subwoofer in.

It will take on average 2-3 weeks for your order to be completed.


Once your order is placed, you will receive a confirmation email. No other updates or emails will be sent until your order is completed at which point you will receive an email with tracking information.

White paper trimmed / stacked to spec works great for shimming — use enough where it is snug but not so tight you can barely get the coil in the gap.
For glue, we suggest using CA glue or Loc-Tite 5-minute epoxy with mixing tubes  to glue the spider to the frame and E6000 for the surround and dust cap.
Make sure to rough up the glue surface of the dust cap and sand and clean the frame beforehand.
For more in depth information on how to recone your sub, you can check out our how-to recone video.

We cannot warranty DIY Recone assembly issues.
We can ONLY stand behind labor that we perform.
Manufacturing defects in the kit itself are our responsibility but installation is 100% customer responsibility (this includes ticking, rubbing, broken parts, etc.).
Thank you for understanding.
