What does hpl+ mahogany mean in guitar material?

There must be no plywood! Because HPL and plywood are two different technologies, HPL is better than plywood guitar in practicality, timbre and volume.

The netizens downstairs don't know if they have ever used a piano made of HPL, which is a kind of wood fiber compressed material. The biggest difference between HPL and plywood is that

HPL is harder and more durable than plywood.

HPL can be very thin, the vibration of the piano box is better than that of the plywood piano, and it is loud and explosive.

HPL is not affected by the weather, and plywood is compressed with wood, which is afraid of the temperature difference of the weather.

Under the popular science, the material piano-making technology of HPL is not only known by Martin Company, but also by domestic piano-making companies. I'm using domestic products myself, which is much cheaper than foreign ones.
