The biggest problem is finding craftsman. There are lots of logs and marble in Thailand but there are only so many master craftsman who can carve marble and wood into a nOrh loudspeaker. I am not worried about running out of logs as much as I am worried that the price will become higher. Today, there are still plenty of the trees we use. We encourage and support proper land management so that there will be a supply of logs for a long time.
Trees are a renewable resource.
If these trees are properly managed, they should be a supply of wood for many years. The Thai baht is now valued at a historically low value. If the baht price increases, the labor and wood costs will automatically increase. The issue is not if there is a sufficient supply of logs, it is how long can I obtain these logs and keep the price of the nOrh loudspeaker down. Speaker manufacturers are quick to promote features that don't cost them any money and often don't impact the sound.
