We have now created a high-performance wooden acoustic reflector with casters, which has been long awaited by performers, music groups, facility staff, and school music teachers.
 
The advantage of portable acoustic reflectors is that they can be easily moved to wherever and whenever needed, allowing you to easily maximize the acoustic effect.
 
Incredibly lightweight and affordable
 
Once moved, simply lift the panel to use it immediately!
 
Made of wood, it combines natural, rich resonance with clear sound.
 
 
The industry's first stepless vertical angle adjustable upper panel
 
A lineup of products that use anti-viral and anti-bacterial panels

An acoustic reflector is a type of stage mechanism that effectively and efficiently reflects the "sound" played on stage, increasing the volume and reverberation. Concert halls and other venues dedicated to music are designed with meticulous calculations of their acoustic characteristics.
On the other hand, general multi-purpose halls are often used for plays, performing arts, concerts that use PA systems, lectures, ceremonies, etc., and since reverberation can have a negative effect, they are usually stored above the stage and can only be lowered and used for live performances.
Because it is a fairly large piece of equipment, many small and medium-sized halls do not have acoustic reflector installed.
 

Mobile acoustic reflectors are designed to be relatively compact and can be moved to wherever they are needed when they are needed. They can also be stored in a warehouse when not in use, and are generally equipped with casters for easy movement.
In facilities that do not have a permanent stage acoustic reflector, such as multi-purpose small to medium-sized halls, community centers, public halls, schools, auditoriums, gymnasiums, event venues, and lobbies, when performing so-called "live" performances that do not use electrical sound systems, such as classical music, vocal music, choirs, and brass bands, the "sound" from the stage does not reach the audience seats efficiently and diffuses in all directions, making it difficult to obtain rich resonance and clear sound.
 
It is often said that this makes it difficult for performers to hear each other, which can be an impediment to performance.
 
In such situations and cases, there is a growing need for movable acoustic reflectors, and although they are simple, they have a tremendous effect in improving acoustics, so in recent years they have become considered a must-have item.
 

At schools, there is a high demand for use in gymnasiums, auditoriums, audiovisual rooms, music classrooms, etc.
In particular, we receive many inquiries from students who want to be able to hear their students' voices as clearly as possible for parents at choir competitions, brass band competitions, string and percussion contests, ensemble contests, and music recitals.
There has also been a strong desire to make it easier for students to hear their own voices when performing or singing, the voices of students playing together, and the sounds of musical instruments.
 
 
For school gymnasiums and auditoriums, 6 to 16 units will be required depending on the size of the stage, and we will propose the most efficient and optimal number of units and layout plan.
 
 

We delivered to a large underground commercial facility at the request of a long-established piano workshop that deals in vintage Steinway pianos.
They regularly hold classical concerts in the event space, but noise from the hallways, talking, escalator announcements, etc. mixed in, meaning that the delicate music and sound were not conveyed to the audience. The performers were also bothered by the surrounding noise, as the sound escaped in all directions, making it difficult for them to perform.
 
The idea was that by introducing the OTHC series and creating a pseudo-wall surface, it would create a concert-like atmosphere.
Using movable acoustic reflectors in open spaces not only improves acoustics as mentioned above, but can also help prevent sound from the event from leaking to other shops.
 

 
The rental company approached us because they wanted to be able to rent out the equipment for each event, such as classical concerts sponsored by local governments, as well as annual choir competitions, brass band competitions, and ensemble contests.
In addition, they said that they could expect a high occupancy rate, as there are many requests for the equipment from organizers, performers, and music groups for live performances and concerts in commercial facilities and event spaces that do not use PA systems.
 
Even though they are portable acoustic reflectors, it is likely that many venue owners are hesitant to actually purchase and maintain them, so being able to use them for each event is likely to be beneficial for both parties.
 

 
Since the COVID-19 pandemic, interest in hygiene has increased, and there have been many calls for the introduction or replacement of anti-viral and anti-bacterial products in stage and stage equipment at schools and public facilities.
To create a safe and secure facility environment, the OTHC series has been upgraded to use SIAA-certified materials with anti-bacterial or anti-viral and anti-bacterial treatments on the entire surface of the panel.
 
 
Additionally, we strive to reduce the use of petroleum-related materials in packaging and use recyclable materials wherever possible.
