Mobile Bluetooth Sonar Active Monitoring Speaker with Kevlar Driver and 25W Amplifier

This active monitoring speaker is designed for listening situations where clear separation of low and high frequencies matters. It uses a 3.5-inch Kevlar low-frequency driver and a 1-inch spherical high-frequency driver, powered by a 25W single amplifier. The stated frequency response is 80-20kHz, with a peak sound pressure level of 100dB and a crossover frequency of 2.8kHz. Input impedance is 10kΩ. Connections include TRS 3.5mm, TRS 6.35mm, and RCA inputs, plus a TRS 3.5mm headphone output. Volume is controlled from the front knob, and an inverting adjustment sits behind a rear circular hole. The speaker comes in black and in E3.5, E3.5BT, E4.5BT, and E4.5T style options, with a 220V US electrical outlet option. Two cabinet sizes are given: 162 × 141 × 210mm and 180 × 163 × 241mm.

Features and Construction

The construction centres on a two-driver layout and a built-in amplifier. This is useful when you want an active speaker that can handle monitoring tasks without needing a separate power amplifier. The listed crossover point and driver sizes give a clear starting picture of how the audio band is divided between the two units.

Material and Build

The low-frequency driver is a 3.5-inch Kevlar unit. Kevlar is named in the source as the cone material, and the high-frequency driver is described as a 1-inch spherical high pitch unit. The single amplifier is rated at 25W. Input impedance is 10kΩ, and the crossover frequency is 2.8kHz. These are the stated construction details, and they define the speaker’s basic active monitoring format.

Size and Practical Fit

Two cabinet sizes are listed: 162 × 141 × 210mm and 180 × 163 × 241mm. The smaller and larger options give different footprints for placement on a desk, shelf, or studio surface. The front volume knob and rear inverting adjustment are positioned for access during use. The black finish keeps the speaker visually neutral in most setups.

Uses and Placement

This speaker suits studio monitoring, desktop audio, and home listening where TRS or RCA connections are available. The headphone output adds a private listening option. Because the source lists multiple style options and two sizes, it can be matched to different spaces and equipment arrangements.

Event or Professional Use

For professional or project studio use, the TRS 6.35mm and RCA inputs allow connection to a range of audio interfaces and mixers. The 25W amplifier and 80-20kHz frequency response support monitoring of recorded material. The front volume knob allows quick level changes, while the rear inverting adjustment can be accessed when needed. The 100dB peak sound pressure level is stated for the speaker.

Everyday Home Use

At home, the speaker can be connected to audio gear through the TRS 3.5mm, TRS 6.35mm, or RCA inputs. The TRS 3.5mm headphone output is useful when you want to listen without using the main speaker output. The black colour and two size choices make it easy to place in a room. The active design means no separate amplifier is required beyond the built-in 25W single amplifier.

Benefits and Buying Value

The practical value comes from the active design, multiple input types, and the included connection accessories. The speaker is supplied as a two-unit package with a power cord, instructions, a one-split-two connection line, and a speaker connection cable. That means the main connection items are included with the audio units.

Reuse and Low Maintenance

With no separate amplifier needed, the speaker keeps the setup simple. The listed materials and construction are fixed, so care should focus on keeping the cabinet and drivers free from dust and moisture. The source does not list detailed maintenance instructions, so only basic, low-risk care is appropriate. The included cables support connection and reuse with compatible equipment.

Why Choose This Product

Choose this active monitoring speaker if you need a 25W unit with a 3.5-inch Kevlar low-frequency driver, a 1-inch spherical high-frequency driver, and a 2.8kHz crossover. It provides TRS 3.5mm, TRS 6.35mm, and RCA inputs, plus a TRS 3.5mm headphone output. It is available in black and in E3.5, E3.5BT, E4.5BT, and E4.5T styles, with two listed sizes and a 220V US outlet option.
