TR-17sp 1DINサイズの電流駆動スピーカーアンプ

TR-17sp 1DIN size current drive speaker amplifier


The TR17sp is a compact, full-range speaker amplifier designed to fit a 1-DIN size.
While typical amplifiers control the diaphragm's position through voltage, a current amplifier like the TR17sp controls the movement (velocity) of the diaphragm. By using the actual current flow for feedback rather than voltage, it achieves sharp diaphragm responsiveness. From the speaker's perspective, there is less damping effect imposed by the amplifier, which minimizes diaphragm shock resonance. This allows for extremely clear mid-to-high frequencies, making it ideal for phase-sensitive playing, such as ASMR. Additionally, the traditional issue of insufficient bass damping in current-driven systems is resolved by a circuit that smoothly transitions to voltage-driven operation in the low-frequency range.
