t.akustik Spektrum D20 Diffusor
Professional music gear - detailed information and where to buy
This t.akustik D20 is a solid, budget-friendly option for tackling flutter echoes and first reflections in smaller project studios or hi-fi rooms. The prime number design delivers predictable diffusion, and the shallow profile means you can use it even if space is tight – just don't expect miracles with deep bass.
Product Description
- t.akustik Spektrum D20 Diffusor
- Diffuser
- Two-dimensional QRD diffuser (based on prime number 7) with hemispheric sound scattering
- Design frequency: 1307 Hz
- Upper cutoff frequency: 2256 Hz
- Scattering effect at low frequencies down to 654 Hz
- High-quality processed QRD diffuser
- Two-dimensional diffuser develops its scattering effect evenly in all spatial directions
- Despite its low depth
- broadband effect in the range from 654 Hz to 2256 Hz
- Suitable for dissipating hard reflections in the middle frequency range and thus minimizing sound colourations due to flutter echoes and strong first reflections
- without overpowering the room
- Temporal dispersion of the sound
- small spaces appear acoustically "bigger"
- Upgrading the sonic properties of a hi-fi listening room
- home and project studios or recording room
- Exterior frame construction made of clear lacquered 12 mm birch multiplex
- Cell dividing walls made of clear lacquered 6.5 mm birch multiplex
- Dimensions 600 x 600 x 100 mm
- Cell size: 76 x 76 mm
- Weight: 7.7 kg
- Includes 4 mounting clips for wall mounting (screws not included)
PROS
- • Effective broadband scattering across a useful mid-frequency range
- • Hemispheric scattering provides even coverage, minimizing dead spots
- • Compact depth allows for use in smaller, more constrained spaces
- • QRD design based on prime number 7 offers predictable and controlled diffusion
CONS
- • Limited low-frequency performance; won't address serious bass issues
- • Primarily effective in the mid-range; requires complementary bass traps
- • Appearance is purely functional; may not suit all aesthetic preferences

Frequently Asked Questions
It’s most effective in smaller rooms (under 300 sq ft) where first reflections are more prominent; larger rooms will need multiple units and bass trapping.
Use appropriate drywall anchors or screws suitable for the wall material and the diffuser's weight – something rated for at least 10 lbs per mounting point is recommended.
The prime number design ensures more consistent and predictable scattering, avoiding 'hot spots' of reflection and providing a more even sonic landscape.
