GRO

Rich Room Filling Sound

You need to hear it yourself.

Gro is built for listeners who want their music to feel honest — full of detail, clarity, and life. It delivers vocals and deep tones with stunning precision, while upper frequencies remain vibrant and free of compression. Its treble is fast and smooth, revealing fine percussive textures without harshness or edge. Transients are sharp and well-defined, ensuring clarity across the entire frequency range.

Despite its compact form, Gro’s bass is articulate and dynamic, offering both tenderness and real impact when the music calls for it. The integration between drivers is seamless, the voicing natural and unforced, with no metallic sharpness in the highs. Its refined 3D soundstage draws the listener deep into the performance, as if the artist were standing right there in the living room — alive and performing just for you.

Driver Matching

All drivers are pre-matched into uniform pairs before assembly. This ensures consistent behavior between left and right loudspeakers, improving stereo imaging, tonal alignment, and overall coherence.

Crossover Design

Gro uses a 12 dB/octave Linkwitz–Riley crossover at 2750 Hz, incorporating T.I.M. (Transient Intermodulation) reduction circuits.
The topology is designed for clean phase behavior, smooth driver transition, and stable off-axis performance — contributing to Gro’s balanced, unforced presentation.

Tweeter

The tweeter is a 38 mm ring radiator chosen for its ability to reproduce overtones with clarity, openness, and high resolution.

It is powered by a neodymium motor system, giving the unit exceptional speed, transient accuracy, and control.

The design avoids intrusive resonances, maintaining linearity and preserving detail even at low listening levels.

Driver

For mid and low frequencies, Gro uses two 5-inch woven mineral-reinforced polypropylene cone — selected for its excellent internal damping and naturally smooth frequency response.

An optimized center bullet extends the upper frequency range and reduces compression caused by temperature variations in the voice coil.

The lower suspension minimizes airflow noise and cavity resonance, contributing to a clean and controlled bass response.

Ready to Connect

Equipped with WBT terminals, featuring a special hybrid internal wiring configuration of pure copper and silver plating, our speakers deliver unparalleled signal processing with minimal degradation.

Unique by Nature

Our speakers are designed with both precision and individuality in mind. If you wish, you can even choose a custom color to make them truly yours.

Engineered for Pure Sound

Equally distinctive is the trademarked pattern on our aluminum front baffle — recognized for its unique look, and engineered to reduce unwanted reflections for a pure, immersive listening experience.

Every detail is intentional, and every material carefully chosen.

A Review

If feelings cause a few tears of musical involvement and participation, the Danes should call its mission accomplished.

 "When envision[ing] its actions with my ears, I hear a lot of dry percussive noises (…) Those are all very quick details which come and go rapidly (…) Gro’s tweeters had my ribbon-groomed ears lack for nada." 

 "Under domestic conditions (…) Gro challenges conceptions on how modern small drivers in an inert box can add up (…) Gro’s bass can tickle tenderly (…) but also thuds with surprising smash when dynamic demands mean business." 

"Gro certainly reinforces existing systems which aim for linearity, dynamics, and clarity (…) Its driver integration is seamless, its treble suave without any metallic undertones (…) more about feelings and the belly than looking at things with the head."
