It adopts a two-way three-unit crossover circuit design, with a PVC gray veneer finish that gives it a clear layered appearance. The mid and high frequencies are smooth and transparent without distortion. The tweeter (3 inches) and woofer (10 inches) units use original Taiwan-imported paper cones. The voice coils are made of high-temperature-resistant glass fiber material. With a high-configuration aerospace dual magnetic circuit, it offers higher safety and reliability. 1. System Type: Two-way Three-unit Low-Frequency Reflex Speaker 2. Frequency Response: 65Hz-18kHz +3dB (Note: It's unusual for a speaker to have a frequency response ending at 18Hz and then suddenly jumping to +3dB; typically, the "+3dB" would denote a tolerance or deviation over a specified range. However, based on the context, I'm interpreting it as the range being 65Hz to 18kHz with a deviation of +3dB. If this is incorrect, please clarify.) 3. Sensitivity: 98dB/1W/1M ±2dB 4. Rated Power: 150W/8Ω 5. Peak Power: 300W/8Ω 6. Tweeter Unit: 3" x 2 7. Woofer Unit: 10" x 1 8. Sound Pressure Level: 115dB 9. Connector: 2P HiFi Terminal Block 10. Dimensions: 500x295x300(mm) 11.
