In the "Best Computer Speaker" poll by Wirecutter, the M-Audio AV 40 took first place, offering an excellent price/performance ratio in its price range. Despite its compact size, the AV 40 is full of explosiveness, with a well-balanced midrange and high-bass performance, and the process of maximizing sound stress is very smooth without noticeable distortion. Moreover, the front panel of AV 40 has a knob design to adjust the volume, which can provide 3.5mm headphone output, which is very convenient to use, and the price is about 1300 yuan. Users who don't mind a slightly larger size can also choose the M-AUDI0 BX5 Carbon, which is a recommended product for PCMag, and the quality is also very good, with a price of about 1200 yuan.
