Universal size for 12" speakers
Dome diameter: 80 mm - recommended for most of the guitar loudspeaker with average beaming

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.

Both systems with balanced gain

This tube is recommend to tame the gain of an amp and make it sound "sweeter". The 5751 has only a gain of 70 instead of 100 like the typical 12AX7/ECC83 tube type and can be used as a drop in replacement for 12AX7 / ECC83 tubes.
