Sinbosen Point source speaker T-24N and subwoofer BT-30
T-24N: Precision-Designed Two-Way Point-Source Speaker
This two-way system combines a 12-inch low-frequency driver with a 1.4-inch high-frequency compression driver, achieving impressive acoustic performance within a compact enclosure. The enclosure is constructed from 18mm birch plywood with internal reinforcement, ensuring sufficient rigidity while controlling weight and reducing resonance-induced coloration. The mid-low frequency transition is natural, and the high frequencies are delicate and not harsh, with a maximum sustained SPL of 132dB.

T-24N and BT-30 combination:
Precise Frequency Response Tuning: The frequency response of the two enclosures is optimized and matched, with the T24N's solid low-frequency limit (55Hz) and the B30's smooth high-frequency roll-off (150Hz) forming a natural overlap region, ensuring a seamless transition across the entire frequency range.
Sound Field Consistency Guarantee: The T24N's point source characteristics ensure accurate projection of the mid-high frequencies, while the B30's directivity control (especially in a cardioid configuration) optimizes low-frequency coverage. Together, they provide consistent frequency balance and sound image localization throughout the listener area from 40Hz to 20kHz.
Power and Dynamics Balance: The T24N's 600W low-frequency power and the B30's 1600W processing capability create a reasonable gradient, providing a system peak SPL of over 135dB while maintaining ample dynamic headroom to handle transient peaks.
