Urushi finish requires painfully long process. If you need large order, please contact us before placing your order.
If you get an extra ordinary transparent speakers, you need to upgrade rest of the Audio system. For example, John Tucker @ Exemplar Audio started building amplifier for his horns. He knew his speaker can do better and Mr.Teramoto also had same challenging issues.
We builds amplifiers for our speaker customers only. They use custom manufactured FINEMET transformers and Urushi finished capacitors. They simply do not have production capacity.
All Our Transformer is designed and manufactured by Mr Suzuki. He is the most well known field coil speaker designer in Japan, as well as FINEMET Transformer designer and manufacture. He also supplies transformers to well known Japanese high-end audio manufactures.
Our custom FINEMET Transformer has far better dynamic phase response than transformers with conventional core materials. We spent about a year trying to find capacitors that can perform well with our custom FINEMET Transformers.
We gave up finding off the shelf capacitors, and Mr Teramoto came up with his magic. Urushi finished capacitors. He needs to treat them one by one with his hands.
Urushi material acts like poison ivy juice. If you touch them before it cured, you will remember it for life!
