The copper and aluminum are integrated into a whole, and the two different resonant frequencies are blended into one, so as to obtain a high-quality listening effect that takes into account both HIFI and music. The key to good sound lies in the diffraction groove designed at the waist, which can effectively diffuse the standing waves at the bottom of the equipment, make the sound bottom cleaner, and sufficient low-frequency energy. Effective noise reduction: Use these sturdy speaker spikes to unnecessary vibrations and noise. They are made of aluminum alloy to minimize noise interference and a quieter and more pleasant audio environment. The transient response is better, faster than pure wood, making the music more vivid, energetic, and unimpeded, and more intimate and warm than pure metal; the low frequency is full and not turbid, the mid-high frequency is penetrating and round, the parts are clearly integrated, and the depth is strong. Non-destructive installation by bonding, no need to damage or the bottom of the equipment, as long as it is flat, it can be installed in any desired position, flexible and unrestricted.
