High performance 2WAY system centered on wood horn
Yamamoto Sound Craft The YS-500 is a high-performance 2-way speaker system that uses a 38cm woofer and is mainly composed of the Woodhorn SS-500. With a unique design that sets it apart from conventional closed-back and bass-reflex models, we have created a magical and dynamic sound that will make you want to explore a labyrinth of sound.
High efficiency design with wood horn and neodymium magnet
- High performance unit: 38cm diameter woofer and 1 inchthroat-Equipped with a powerful magnetic circuit that uses neodymium magnets in both horn driver units.
- High efficiency: The main appeal is that it achieves a high conversion efficiency of 98dB/W/1m, and that sufficient sound pressure can be obtained even with a low-output vacuum tube amplifier of only 1~2W**.
- SS-500 Wood Horn: This is a high-performance horn manufactured using a luxurious method of laminating and carving out laminated cherry wood. Its biggest feature is that it provides extremely smooth frequency characteristics.
"Rear-open enclosure" that takes advantage of the benefits of flat baffles
- Design philosophy: In order to avoid the ``muffled, undefined sound'' that sealed and bass reflex types tend to suffer from, we inherited the good qualities of the flat baffle system, which is the ``lively and responsive sound''**.
- Structure: Adopts an enclosure with open rear and bottom surfaces. Despite its relatively compact size of 460mm wide and $560mm deep, it is designed to provide the same characteristics as a 1mx1m flat baffle.
- Good sound: The enclosure is made of cherry laminated wood with good sound quality, and the connection parts are reinforced with solid Asada cherry wood. The good resonance of cherry wood, which is also used for musical instruments, brings a beautiful sound that touches the heart.
Simple network with excellent phase characteristics
- 6dB/oct method: Adopts a **6dB/oct type** with excellent phase characteristics and a natural connection between units.
- Only 3 parts: The network circuit consists of only three parts, including the attenuator part for level adjustment.
- Carefully selected parts: The filter coil uses a copper foil coil with a cut core of $100\text{W}$ capacity, and the capacitor uses a polypropylene capacitor manufactured by Dearborn in the United States, sealed in an ebony case.
- Sound quality measures: The speaker terminals are large terminals machined from pure copper. A brass angle is installed on the back of the woofer to reduce the effects of reaction from the driving part, contributing to improved sound quality in the bass range.

Straight extrusion and penetration power
It has received extremely high praise from music critics for its unique design and sound quality.
"A well-balanced frequency band. Straight extrusion with no twists and turns is comfortable."
Despite being an open-back type, it has been praised for its straightforward and well-balanced frequency range, and is a well-liked system with a pleasant straight extrusion.
"A theater-style speaker that competes with mid-range penetrating power and line thickness."
The penetrating power of the mid-range and the thickness of the line are noteworthy, allowing you to enjoy theatrical sound. The low range has the potential to growl loudly by adjusting the compensator, and is characterized by a lively and clear sound. This is a magical and unique piece of work that is especially recommended in combination with a vacuum tube amp.
