Greetings everyone,
I have a question about phase angle of speakers in impedance measurements and specifically, how does it impact the load on amplifiers? I currently have a LM1875 gainclone, and want to know generally how angle determines whether the load will be too hard for it or not. For example, 5.5ohms at a -45 degree phase. ![]() tldr: The speakers have an 85dB @ 1w/1m sensitivity, and I listen from 2m away. How loud can I go before the amp clips, and does phase impact whether it clips earlier? If so how do I figure this. Thanks. Last edited by Shike; 28th October 2010 at 04:26 AM. |

read ESP on this topic.
There are other Websites that look at reactive speaker loadings and the effect it has on the amplifier. This is not a minor problem. It is complex and serious. It can blow up amplifiers. It will activate the Spike protection in a 3886. What protection/limiting is built into the 1875? It can ruin the sound quality if you try to play inappropriate sound levels from an amp that is severely current limiteHow loud can I go before the amp clips, and does phase impact whether it clips earlier? If so how do I figure this.d by design. Quote:
