Edifier T5 Hi-Fi Subwoofer 1 pc

Edifier T5 Powered Subwoofer — Deep, Accurate Bass for Bookshelf and Home Theater Systems

The Edifier T5 is a compact powered subwoofer designed to extend the low-frequency reach of any 2.0 or 2.1 speaker setup. With an 8-inch front-firing long-throw driver and a 70 W RMS closed-loop Class-D amplifier, this model reaches down to 38 Hz, adding weight and rumble that bookshelf speakers alone cannot reproduce. Listeners who want music, movies, and games to feel physically present will find it a natural fit.

Texas Instruments DSP and Closed-Loop Amplification

What separates this subwoofer from entry-level models is the Texas Instruments high-performance analog front end paired with a closed-loop digital Class-D amplifier and an integrated DSP. This combination handles low-pass filtering and phase control with precision, allowing the sub to blend cleanly with the main speakers. The 18 mm MDF enclosure further reduces cabinet resonance, keeping bass tight at higher listening levels.

Driver and Amplifier — How Much Bass the Unit Can Produce

The heart of any subwoofer is its driver and amplifier pairing. This unit uses an 8-inch (220 mm) long-throw woofer driven by a 70 W RMS Class-D stage. Long-throw geometry lets the cone move more air per stroke, producing the physical sensation of bass in a room.

• Driver: 8-inch (220 mm) front-firing long-throw woofer — moves more air per stroke for deeper, more physical bass
• Amplifier Power: 70 W RMS Class-D — high-efficiency switching supply with closed-loop feedback for clean output
• Frequency Range: 38 Hz - 200 Hz — reaches sub-bass notes bookshelf speakers typically cannot reproduce

Low-Pass Filter, Phase, and Volume — Tuning to Your Room

A subwoofer only sounds good when properly integrated with the main speakers, and the rear-panel controls provide the three adjustments needed. The low-pass filter sets the upper limit of reproduced frequencies, the phase switch (0° / 180°) aligns sub output with the mains to prevent cancellation, and the volume knob balances sub level against the satellites. An integrated DSP handles the low-pass slope digitally for a cleaner crossover than analog filters.

• Low-Pass Filter: adjustable, 30 Hz - 160 Hz range — matches the sub's upper limit to the bookshelf speakers' low-end roll-off
• Phase Control: 0° / 180° switch — aligns subwoofer output with main speakers for coherent bass
• Signal-to-Noise Ratio: ≥ 85 dB(A) — quiet operation with no audible hiss between tracks

Connectivity and Build — RCA Pass-Through and MDF Construction

RCA Signal In and Signal Out ports on the rear panel mean this subwoofer works with speakers that have a dedicated subwoofer output as well as those that do not. When the main speakers lack a sub output, the source feeds into the sub's Signal In and passes through Signal Out to the speakers, letting the sub tap low frequencies without interrupting the signal path.

• Audio Inputs: RCA Signal In / Signal Out pass-through — compatible with desktop, bookshelf, and home theater systems
• Cabinet Material: 18 mm MDF with wood-grain vinyl finish — minimizes resonance and vibration for tighter bass
• Dimensions (W × H × D): 278 mm × 300 mm × 336 mm — compact enough for floor placement near a wall or desk corner
• Net Weight: 8.56 kg — substantial cabinet mass that resists unwanted vibration

Who Should Buy the Edifier T5

The Edifier T5 is the right choice for listeners who already own a pair of quality bookshelf or desktop speakers and want to add real low-end without rebuilding their entire system. It pairs naturally with Edifier models like the R1280DBs, R1700BTs, R1855DB, S880DB MKII, and QR65, and works with any amplifier or powered speaker that has an RCA line-level output. Home theater users get 38 Hz extension for movie soundtracks, while desktop gamers and music listeners get the rumble small speakers cannot deliver on their own.

Edifier — Two Decades of Accessible Hi-Fi Engineering

Edifier has been designing loudspeakers and audio electronics since 1996, building a reputation for delivering genuine hi-fi performance at prices that do not require a custom installer. The T5 reflects that philosophy: a real MDF cabinet, a Texas Instruments amplifier platform, and DSP-based crossover control rather than the plastic enclosures and basic analog circuits found in many budget subs.
