It was properly placed in a box and secured with a protective plastic case.
I thought it was the most reliable store.
You can buy with peace of mind.
The key product has a slightly high-end sound quality, I think...
Overall, I would say it's good.
What I liked was that the color of the actual aluminum cone was better than in the photo.
Maybe because of the anodizing process, the color of the burnished silver was the best.
Before the unit arrived, I used a self-made mahogany plywood box with a thickness of 18mm in a rear bass reflex shape.
In the first place, it was the leftover material from the mahogany plywood used when making a large speaker system, so the board thickness was even 18mm.
The interior of the side panel near the mounting baffle plate and the unit has been cut about 8mm with a trimmer to ensure that the sound from the back of the unit properly escapes into the interior.
