My original box for the 18 that is in my trunk right now was built into the trunk. Which is expected with a large amount of air space needed. When I built the box i placed the top plate into position with the sub already mounted, knowing that i would have to install the sub while in process of building the enclosure. It worked out perfectly and Ive had much success with the design.
807tubenut is designing my latest build which will consist of a much bigger 18" , with more motor force and more excursion. Knowing this the same box design will not work as the cone will hit the top of the trunk (more than 3 inches of excursion).
I want to be able to remove the sub whenever I want also. This box that is installed now contains a 20"x25" access panel on the front of the box so that i can wire the sub to 2 ohms or .5ohm whenever i want. I was thinking of incorporating this into the next design.
(note: sub up, port back)
By using the access panel idea, i could remove the whole front baffle to access the box's interior. inside the box i was going to make the top baffle 1.5" thick with a "mounting ring" that is hollowed out but big enough to let the sub slip into place. essentially i am inverting the sub from inside the box.
This would give me an 1.5" inches to help with the excursion problem as well as giving me the possibility to access the sub and pull it out of the mounting ring.
My question to you:
Has anybody had this problem or does anyone have a creative way to fix my problem?
