The upgraded trims come in two types. Your choice of wood plus stain would be $300 up charge. $500 would get you automotive paint finish (super glossy) of any car paint of your choice. These were the prices several months back. You may, want to also have rubber feet attached to the bottom for $50 extra to protect the paint surface from touching the ground.
If you go for the 118HT, you may want to ask Jeff about the lower tuned version(18Hz) that should not cost extra.
I’m very happy with my 118HTs. They are much more subs than I need!
