I just received a pair of fullrange driver to test from Lii Audio.
My purpose is to develop a no-compromise enclosure and make test.
Model is Crystal 10, a double cone, 10" fullrange with high sensitivity. I know someone in the forum could appreciate the development so I decided to post.
I'd like to expose a brief visual description of the content, with tons of pictures.
The main protective box is a nice and sturdy wooden unit, pretty well made, packed in a good cardboard. Material is plywood, 8mm thick assembled with glue, painted with transparent. Attention to detail is visible, all edges are trimmed to avoid splinters, thing not common talking about wooden box. Considering the quality of material and internal meaures 30x30x15cm, 13.5L.
Inside there are a couple of dense and thick shaped foam to keep the unit in place. The full range is inside a plastic bag. Good quality labels outside, with brand name in Latin alphabet and Chinese characters.
The purpose of this strong box is to save the driver from possible (and frequent) damages reported in the shipments.
