I am putting out a feeler for 4 of the 8 Terraform D18's that Mark produced in 2014. These are 4 incredible ported subs with dual 18's, utilizing the same driver currently utilized in the Seaton F18 offerings. Included is the powerful Speakerpower sp2-12000 amplifier with Mark's included DSP settings.

Subs are each in excellent physical and playing condition. The subs have seen limited use, due to my purchase of 8 DIY Othorns.

Asking $14,000 obo. Local pick up in southern wisconsin.

Thanks DC3! I went completely overboard and got 8 DYI Othorns built, which are those big black towers behind the Seaton gear in the picture above. Currently, I am only utilizing the Terraforms below 20 hz, which is a lot of funds to have invested in subs for such a small frequency range.

I have been trying to focus a bit more on atmos surround, and since I have way more bass than anyone needs with my DIY subs above 20 hz, I figured list these great subs for someone else interested in obtaining the ultimate in low frequency bass! The ported design on The Terraforms makes these Terraforms perform at multiples of what 18" drivers would do on their own. It has to be heard to fully understand what they are capable of.

Also, I am considering a possible move in the near future, and so trying to prepare for a possible move, if that should happen.

Each sub is 54" tall x 28"'deep x 22.5" wide. Each sub cabinet weighs approximately 260 pounds. The ported design of each sub cabinet allows each one to perform at multiples of the 18" drivers, and the curved port of the cabinet is designed to reduce port chuffing.

Thanks!

Got it....i have 4 F18's and 4F2's...more bass than I need in my room as well.  Even turned down the bass is hot, so I can't imagine the 8 Othorns and Terraforms.  Nice setup Man.  

GLWS!!
