It is small and doesn't require power, but the sound: the sound is great. It's ecofriendly. It's green. It's passive. It looks great. It sounds great.
This little guy is approximately 6” by 5” by 4”. The opening for the phone is 3-3/8" x 3/4" and will fit most any phone, including the case.
This is created with several different types of wood. The bell or horn is created with alternating walnut and oak, joined in a 15-degree 6-sided bell.
The front piece of wood is also walnut, cut locally from my neighbor's walnut tree. It has been dried for over a year sold and has great color, variation and has a beautiful grain pattern to it.
The middle piece is maple and back pieces of wood is walnut. It has been sanded to 600 grit and is finished with Watco Danish Oil.
Expertly made, pretty wood, small in size and big in sound. And it works for an amplified speaker phone!
