Hi-Fi Speaker

Foundation of high-fidelity

The Hi-Fi speaker S45HK equipped with has several advantages. UKP diaphragm brings clear vocals and excellent frequency response. Rubber suspension contributes to smooth frequency response, high-fidelity sound output and deep powerful low-frequency extension. What's more, S45HK benefits from sensitive electromagnetic induction, completing transformation of electrical signals into stored information thanks to the big size magnet.

Dual Horn Echo Chambers

Bass amplitude enhancement

In the chamber, the mid-low frequency rearward sound waves undergo phase transformation through this structure and combine with the forward sound waves to achieve bass amplitude enhancement.

Dual Horn Echo Chambers

Feel like a 50W subwoofer

Under the compact design, the S45HK innovatively introduces “horn echo chamber”. This structure draws inspiration from the design of horn. Compared to traditional design, this structure is much more complex and comprises left and right “dual horn echo chambers”. The combined effect can deliver a bass experience equivalent to a 50W subwoofer. The two echo chambers operate independently, eliminating interference and achieving high-fidelity sound.

Golden Curvature Amplification Port by Polymeric Rigid Material

High-fidelity makes you enjoy

After thousands of simulation, the design of the amplification port was confirmed with a changing curvature, and brings a reduction of 5% distortion in low-frequency.

Polymeric rigid materials are used for the chambers, boasting ultra-high strength and hardness, effectively preventing resonance within the chamber during sound transmission, and contributing to 3dB optimization of wind noise.

Low-Frequency Algorithm

Suit your ears

Peak Sound Pressure Enhancement Algorithm effectively boosts the sound pressure level by 4dB in the 60-90Hz range.

Dynamic Balance Algorithm compensates for the low-frequency components at low volumes to enhance the bass perception, while at high volumes, it moderately reduces the low-frequency output to minimize distortion.

*The sound pressure level boost can be achieved via unique algorithms and technologies.
