Edifier T5s Powered Subwoofer, 70W RMS, 8-inch

Edifier T5s is a powered subwoofer with an 8-inch woofer, RCA connections and adjustable low-pass and phase controls. Its wired setup suits compatible speakers and amplifiers, but connection requirements matter, particularly when the source has no subwoofer output.

At a glance

Listing claims 70W RMS output and bass reaching 35Hz, while the separate frequency-response field says 32 KHz. Treat these as inconsistent listing details, not a settled response specification.
Adjustable low-pass filter from 30Hz–160Hz and 0°/180° phase selection are listed for matching the subwoofer to a speaker setup.
The listing describes a front-firing driver, right-firing acoustic port and 18mm MDF cabinet.
Auto-standby is claimed after 15 minutes of inactivity.
RCA is the listed connection. The product description specifies a wired setup and no external receiver requirement.

Pros and cons

Pros

RCA input and output connection options are described for systems with a subwoofer output and certain line-in speaker configurations.
Low-pass and phase controls allow adjustment to the connected system.
Auto-standby is claimed to activate after 15 minutes of inactivity.

Cons

What to know before buying

Listing details to confirm

The listing is inconsistent about bass response: the title claims 35Hz, a feature says 35Hz deep bass, and the frequency-response field states 32 KHz. The title also says 70W RMS while the details field says 70 Watts maximum output. Confirm the specifications relevant to your setup before buying. For a source without sub out, the described series connection requires a main speaker with LINE IN. The product details also list cables, but the supplied package inventory is not explicit.

Who is it for?

A good fit for

Buyers adding bass to a wired desktop, bookshelf-speaker or home-audio system with RCA connectivity.
Listeners who want adjustable crossover and phase settings when integrating a subwoofer.

Less suited to

Buyers needing a wireless subwoofer or a connection path based only on Bluetooth, USB or optical audio.
Setups without sub out where the main speaker lacks LINE IN.

Customer feedback is positive about sound and build quality, with value also praised. That may interest buyers seeking a wired bass addition, but the reports do not establish how it will perform in a particular room or system. The favourable aggregate ratings are based on a limited number of ratings and do not resolve the listing's inconsistent response figures or connection requirements.

Positive themes

Customers praise sound quality, build quality and value for money.

Frequently asked questions

What connections does the Edifier T5s use?

RCA is listed. The product description outlines an RCA connection from a sub out, or a series connection through the subwoofer when the main speaker has LINE IN.

Can I use it with a speaker that has no subwoofer output?

The listing describes a series connection from the source through the subwoofer to the main speaker. That main speaker must have LINE IN. Bluetooth, USB, optical and other non-wired inputs are not supported for this route.

What frequency range does the listing claim?

The title and feature text claim 35Hz deep bass, while a separate frequency-response field states 32 KHz. These listing details conflict, so neither should be treated as a confirmed response specification.

What controls are listed?

The feature text specifies a low-pass filter adjustable from 30Hz–160Hz and a phase selector offering 0°/180°.
