The custom made wooden pods made especially for the mid-range speakers. They were based on the basic idea of baffles which resulted in a great looking pod.
The construction is based on several ring baffles (3) screwed to the speaker surround and then a flat wooden sheet attached to their back to make it into closed pod. Edges were smoothed and then the seat cover material was applied for the finishing touches which matches the interior and the dashboard. The pod was then attached to the dashboard via a double sided sticky tape. Win (Y)
