Recently was discussing with Bobby (Merlin Speakers) about the RC network termination suggested by him for the Merlin TSM speakers. Bobby explained in his mail in detail how the RC network when used to terminate the amplifier speaker terminal helps to reduce oscillations, ringing at HF and which in turns helps to open upon the sound stage making it more smoother and less fatigue prone.
Over the past 2 days i experimented with his theory and below are my impressions,
- tried initially with a roll-off frequency of 380KHz with a 0.1mfd polyester capacitor for a 4 ohms speaker load. And as explained by Bobby the HF did really get tamed and become more open and less strained. Listen for around 1 hr and was really very pleasing.
- tried again with a roll-off frequency of 100KHz with a 0.33mfd polyester capacitor for a 4 ohms speaker load. This did not reduce the HF as much as the first case and the effect was not that great (though present) as with the 380KHz roll-off.
With the 380KHz roll-off allowed me to increase the volume over 3 o'clock position without any sreachy or eering HF and acutally opened up details in the recording by increasing the dynamic range.
Conclusion: Simpler solutions are always better, cheaper and much easier to implement for complex problems (Theory of Constraints).
