ᐅ Has anyone ever used the Kallax as a hi-fi rack?

I also use my Kallax as an audio rack. It doesn’t bother me that it’s not very solid. What’s important is to position the equipment properly, so not directly against the back panel, and to work on vibration damping.

Cable management is a test of patience here, but cable ties work well. 🙂

It is quite common to use the Kallax as a hi-fi rack. However, the following points should be considered:

- Load capacity: Individual compartments can support up to 13-15 kg (29-33 lbs); use protective pads or supports for heavier equipment.
- Vibrations from the thin wood may affect sound quality; using damping materials is recommended.
- Ventilation is good due to the open design, but keep some distance from walls or absorbers.

For an optimal solution, the shelf could be additionally reinforced. Overall, the Kallax is suitable for a mid-range hi-fi setup.

Exactly, for heavy amplifiers I would definitely place a stiffened board underneath. Otherwise, the wood will warp too much.

Thank you very much for your feedback so far; it has been very helpful.

@onMarcos, your detailed analysis is great, and I will definitely come back to it. I have one more question: How did you attach your back panel? Screws or adhesive? And does that affect the overall stability of the Kallax structure?

The topic of vibrations is also interesting—how much does the sound change due to the damping measures? Is there anyone who has clearly noticed a difference?

I securely fixed the back panel with small Spax screws, which provides significantly better stability in the construction. *I wouldn’t recommend using adhesive since the Kallax panels are made of particleboard, and there’s a risk that the material could warp over time or the bond might break.*

Of course, this is subjective, but I was able to noticeably reduce fluctuations in the low frequencies. Especially if you use sensitive speakers or a turntable, the sound benefits from fewer resonances. Additionally, the damping also protects the electronics by minimizing vibrations.

If you have very heavy equipment, it makes sense to place them on solid wood boards, which further stabilize the Kallax unit.

In my case, the difference was noticeable, especially with vinyl—less background noise. Nothing dramatic, but definitely an improvement.
