Superlux BES5 Active Studio Monitor

BES5 Powered Speaker — Full-Range Sound in a Compact Cabinet

The BES5 is a 100 W active loudspeaker designed for musicians, vocalists, DJs and presenters who want straightforward, no-fuss amplification. A built-in amplifier drives the internal drivers, so there is no need for a separate power amp or rack of outboard gear. Plug in a source, dial in the onboard EQ, and the cabinet is ready for rehearsal rooms, home studios, classrooms and small live performances. The BES5 is the right choice for players and presenters who want a single-box solution that handles instruments, vocals and playback sources with equal confidence.

What Makes the BES5 Stand Out

What separates this cabinet from generic desktop speakers is the combination of a real musical-instrument input set and a true 105 dB SPL ceiling. The 6.3 mm TRS input accepts a guitar, keyboard or dynamic microphone directly, while the 3.5 mm TRS and RCA pair covers laptops, phones, mixers and consumer hi-fi sources. An onboard EQ lets the user tune the response to the room without dragging in extra processors, keeping the signal chain short and the setup fast.

Amplification and Output — Headroom for Real Performance

Power and SPL together determine how loud a speaker can play cleanly before distortion creeps in. The BES5's amplifier section is rated at 100 W, which is enough headroom for solo acoustic sets, singer-songwriter duos, small jazz combos and rehearsal playback at band volume. A peak SPL of 105 dB means the cabinet can keep vocals intelligible and instrument transients punchy in medium-sized rooms, home studios and on small stages without sounding strained.

• Power Output: 100 W — sufficient headroom for rehearsals and small live shows
• Peak SPL: 105 dB — keeps vocals and instrument transients audible at performance volume

Frequency Response — Full-Range Coverage From Bass to Air

A speaker's frequency response defines which parts of the musical spectrum it can reproduce faithfully. The BES5 reaches from 60 Hz at the low end to 20 kHz at the top, which covers the fundamental range of bass guitar and kick drum as well as the high-frequency air that gives cymbals, vocal sibilance and string harmonics their detail. For solo performers this means the cabinet can carry a full mix on its own without needing a paired subwoofer.

• Frequency Range: 60 Hz – 20 kHz — full-spectrum coverage from bass fundamentals to high-frequency detail

Connectivity and EQ — Plug In Anything, Shape the Tone

Input flexibility matters when a single cabinet has to serve as a guitar amp, a vocal monitor and a playback system over the course of one session. The BES5 accepts a 3.5 mm TRS source for phones and laptops, a 6.3 mm TRS source for instruments and microphones, and stereo RCA for hi-fi gear, mixers and media players — all without adapter cables. The built-in EQ provides quick tonal adjustment so the same speaker can be tuned for a bright vocal lead, a warm acoustic guitar or a flat monitoring reference.

• Inputs: Jack 3.5 mm TRS, Jack 6.3 mm TRS, RCA — covers instruments, microphones and consumer audio sources
• EQ: Yes — onboard tone shaping without external processors

Who the BES5 Is For

The BES5 is the right choice for singer-songwriters, solo instrumentalists, home-studio producers, podcasters and small-ensemble performers who need one cabinet that can handle instruments, vocals and playback without extra gear. It suits rehearsal spaces, bedrooms, small clubs, classrooms and conference rooms where a full PA would be overkill but a hi-fi speaker would run out of headroom. Players who want to plug a guitar or microphone straight into the back of the box, dial in a quick EQ curve and start performing will find the workflow straightforward. The 105 dB SPL ceiling also makes it a practical choice for buskers and mobile presenters who need volume that competes with ambient noise outdoors.
