TCL S45H 2.0ch Pro Deep Bass Soundbar with Dolby Atmos

A powerful and immersive home audio experience is delivered by the TCL S45H 2.0ch Pro Deep Bass Soundbar, engineered to provide room-filling sound from a compact, all-in-one design. High-fidelity performance is achieved through a Hi-Fi speaker system featuring a UKP diaphragm, rubber suspension, and large-size magnet structure, allowing electrical signals to be transformed into detailed, accurate sound. Clear vocals, balanced midrange, and deep low-frequency extension are produced for an engaging listening experience across movies, music, gaming, and television content.

Enhanced bass reproduction is enabled by the integrated Dual Bass System and Dual Horn Echo Chambers, where mid-low frequency sound waves undergo phase transformation and combine with forward waves for amplified bass output. Combined with advanced low-frequency algorithms and Golden Ear Tuning, a powerful yet controlled bass response is maintained without overwhelming distortion. Support for Dolby Atmos and DTS Virtual:X creates multidimensional surround sound, while AI Sonic-Adaptation customizes audio performance based on room acoustics and listener position, ensuring consistent sound quality throughout the space.

Key Features 

Hi-Fi Speaker System
High-fidelity sound is achieved using a UKP diaphragm for clear vocals and excellent frequency response, while rubber suspension supports smooth sound delivery and deep bass extension. Sensitive electromagnetic induction and a large magnet structure complete accurate signal transformation.

Dual Bass System with Dual Horn Echo Chambers
Bass amplitude is enhanced by a horn-inspired internal structure that processes rearward mid-low frequency sound waves and merges them with forward waves. Independent left and right echo chambers reduce interference and simulate bass performance comparable to a 50W subwoofer.

Golden Curvature Amplification Port & Polymeric Rigid Material
A specially shaped amplification port reduces low-frequency distortion by up to 5%. Ultra-strong polymeric rigid materials prevent internal resonance and optimize wind noise by approximately 3dB, contributing to cleaner bass performance.

Advanced Low-Frequency Algorithms
Peak Sound Pressure Enhancement boosts sound pressure by 4dB within the 60–90Hz range, while Dynamic Balance Algorithm adjusts bass levels based on volume to maintain clarity and minimize distortion.

Golden Ear Tuning
Professional tuning guided by industry experts ensures deep, detailed, and well-balanced bass, supported by specialized listening and sound absorption laboratories.

Dolby Atmos & DTS Virtual:X
Three-dimensional surround sound is delivered with enhanced depth, clarity, and spatial detail for a cinematic audio experience.

Tutti Choral Technology
When paired with compatible TCL TVs, vertical sound-stage enhancement is achieved to create an uplifting 2.0.2 channel experience.

AI Sonic-Adaptation
Room calibration and personalized sweet spot configuration are supported through the TCL Home application, ensuring optimized sound from any seating position.

Seamless Uni-body Design
A compact, brushed, fingerprint-resistant body is used to reduce internal volume by 30% compared to previous models, minimizing sound leakage while maintaining performance.

TCL TV Ready & Roku TV Ready
Convenient one-remote operation and reduced audio-visual latency are supported when connected to compatible TVs.
