Edifier T5s Powered Active Subwoofer - Deep 35Hz Bass

In this review the Edifier T5s powered active subwoofer is presented as a compact, plug-and-play bass solution for home audio and small home theater setups; its single biggest reason to buy is the combination of an 8-in long-throw woofer and 70W RMS Class-D amplification that produces surprisingly deep 35Hz bass from a space-saving cabinet. The review focuses on real-world use, covering controls, connectivity and the build, so listeners who want tight low end without a large enclosure can decide if the T5s fits their room and speakers.

Key Features

• 70W RMS Class-D amp: Delivers consistent power to drive the 8-in woofer for clear, impactful low frequencies suited to music and movies.
• 8-in long-throw woofer: Reaches down to 35Hz for noticeable sub-bass presence without needing a very large box.
• Adjustable low-pass filter: The 30Hz-160Hz crossover lets users match the sub to bookshelf or desktop speakers for smoother blending.
• Phase selector: The 0/180 degree switch helps align the sub with main speakers to avoid cancellations and tighten the bass.
• Slim MDF cabinet: An 18mm wood cabinet with a front-firing driver and side acoustic port reduces resonance for cleaner, low-distortion bass.
• Auto-standby: Energy-saving mode powers down after 15 minutes of inactivity, useful for everyday home use.

Who It's For

The T5s is aimed at listeners with limited space who want a clear upgrade in low-frequency performance for music, desktop audio, or modest home theater setups. It is especially useful for pairing with active bookshelf speakers that lack deep bass extension.

It is less well suited to very large rooms or for listeners who demand extremely high SPL at club-like levels; users who need wireless sub integration or multiple subwoofer outputs for large multi-channel systems should look at larger or more feature-rich subs.

Pros & Cons

Pros

• Deep 35Hz extension from an 8-in long-throw woofer gives weighty bass for music and movies.
• Built-in 70W RMS Class-D amplifier provides plug-and-play simplicity without an external receiver.
• Adjustable low-pass filter and phase selector allow precise integration with active speakers.
• Space-conscious MDF cabinet and low-profile grille fit into living rooms or small studios.

Cons

• The modest cabinet size limits ultimate output for very large rooms or extreme home theater bass demands.
• No wireless input options, so wired connections are required for setup flexibility.

Our Verdict

The Edifier T5s is a compact, well-controlled active subwoofer that delivers surprisingly deep bass for its size, making it a smart value for listeners who want stronger low end without a large enclosure or separate amplifier. Its precise controls and simple connectivity make it an easy match for bookshelf speakers and small home theater setups, though those with very large rooms or wireless needs should consider larger or more feature-complete alternatives.
