I recently bought a pair of 2nd hand Totem Arro’s.
In one, and only one, of the speakers, I hear a buzz, clearly coming from the lower speaker (not the upper tweeter). I switched the cables, so even if I switch the left & right channel, it is the same speaker which has a problem. It is not the cable (or any of the equipment upstream) that seems to cause the problem. The buzz is very noticeable in the lower bass frequencies (40-60Hz), e.g. when a double bass is playing.
While auditioning the speakers during the twenty minutes or so I listened to them at the private vendors place, I did not notice the buzz. I did play some music with pronounced bass (e.g. ‘Mi Corazon’ by Brandt, Brauer & Frick).
At home, it was only after a couple of days that I started noticing the buzz. And now, I can’t bear it anymore.
Now, my question:
But, to be more sure, in your opinion, is option (b) possible? Given the 2x300w (at 4ohm) of my power amp… which might be too much for the Arro’s.
How loud did I play? In general, the volume knob of the Freya was between 10 & 12 o’clock, but during a couple of (long) evenings it was between 1 & 3 o'clock. Sound levels never exceeded approximately 85dB (at a distance of 2 meters). At this level, the ‘good Arro’, still played a very clean sound.
I want to have the Arro repaired (or I will try to find another pair) since I am super happy with their sound. But I am trying to figure out whether I need to replace my power amp before using the Arro’s again.
I am not familiar with the technicalities of audio equipment, so I hope to get some competent advice of someone who is.

Now, my question:
- Option (a): The buzz was already there when I bought the Arro’s, but I did not notice it at first.
- Option (b): I damaged one of the Arro’s myself with my pre/poweramp combination.
- DAC: Topping D70s, xlr out, output volume 5v (if I am not mistaking)
- Preamp: Shiit Freya+ in tube mode (4x Tung-Sol 6SN7GTB), using balanced in- & outputs.
- Power Amp DIY Hypex Nilai 2x256w at 8Ω, 2x300w at 4Ω, power amp set at low gain (12dB)
- Speakers: 2nd hand Totem Arro, impedance 4 Ω, recommended power 20-80w, sensitivity 87dB
