These drop-in kits are for Sundown Z v.3 subwoofers.
Drop-ins are built using a spacer. If you do not have a Z v.3 spacer, you will need to purchase one.
When these recones are ordered, we are assuming you have the 12-spoke frame that came stock on these subwoofers (Standard 6-spoke for the 18″) . If you are using a different basket or wanting to upgrade to a Sundown tooled frame, please send us an email prior to ordering so we can build a proper recone.
If you’re ordering a 15″ recone, make sure to specify in the order notes which spider landing is being used on your basket. Depending on when your subwoofer was produced, it may be 8″ or 8.3″. If you are unsure, please see the picture below or email us a picture of your set up.
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.

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.
