The new LII-AUDIO W-21 subwoofer from Xizi trumpet in 2024 features a 21 inch bass unit and a newly developed home HIFI pure bass. It is not suitable for stage or professional speakers, and has excellent low-frequency diving. The paper tray and suspension have been re optimized, and the voice coil uses a 100 core titanium skeleton copper-clad aluminum coil, which improves smoothness and sensitivity, making it more suitable for home HIFI and cinema HIFI.

The difference between home HIFI units and professional units (PA units): Home HIFI requires more humanized and personalized speakers, with higher requirements for musicality. The frequency response requirement is wide, and the low frequency should be full and smooth, with good diving, and easy to push. After all, household HIFI amplifiers only have a few hundred watts at most, so the paper tray, suspension, voice coil, and magnetic circuit of the unit need to be designed specifically. PA speakers are professional speakers on the market (generally referred to as PA units) used in professional fields, such as stage clubs or indoor and outdoor performances, which require the speaker to work loudly for a long time and transmit over long distances. This requires the speaker paper bowl to be very thick and the voice coil power to be very high (often several kilowatts). The loud speaker also requires the speaker suspension to be very hard and not have too much amplitude, and the low-frequency diving is not deep. This is why many friends cannot produce low frequencies when using PA speakers at home, and home amplifiers cannot be pushed. Overall, the difference between a home HIFI unit and a professional unit is the difference between a sedan and a truck. For both home and professional use, a sedan is preferred for comfortable riding, while a truck is used for transporting goods
