bFly-audio Absorber 4TUBE for Tube Amplifier

The 4TUBE absorbers are specifically designed for Tube Amplifiers. The 2. Generation now available with screws.

The effectiveness of the 4TUBE Series The transformers of Tube Amplifiers produce by nature mechanical vibrations and so disturb the flow of signals within the internal boards, cables, electronic components and especially the sensitive tubes.

Our 4TUBE absorbers are designed for this weak points of tube amplifiers

The result: The sound is more relaxed, spacial and natural

Our alternative for solid state amps and loadspeakers

Serie MASTER: for solid state amps and loadspeakers; The construction analogous to the 4TUBE
Serie Line: Less effectiveness in comparison with 4TUBE und MASTER, because of absorber construction without cork-rubber
Serie b.DISC: Suitable for hifi components and loadspeakers with spikes

Screwable version: with screws M4/M6/M8 or inner thread M4/M6

For optimum adjustment to the weight of the device we offer two variants:

4TUBE-1 up to 22 kg;
4TUBE-2 up to 50 kg

The effectiveness of the 4TUBE variant: The transformers of Tube Amplifiers produce by nature mechanical vibrations and so disturb the flow of signals within the internal boards, cables, electronic components and especially the sensitive tubes.

These parts are major on the easier side of the amplifier.

So the 4TUBE absorbers consists of 2 different types.

2 absorber with more soft damping for the light side of the device results in an much better damping factor in this critical area.
2 absorber with more hard damping placed on the heavy side.

Possible applications:

With the cork side under the feet of the device
directly under the base plate
furthermore as screwable version available M4/M6/M8.
