[QUOTE="John Roberts, post: 132432, member: 126"] Re: Opinions on limiting for speaker protection A good idea would be to ask the speaker manufacturer of they have any specific recommendations. Just like matching amps to speakers is a little fuzzy using a limiter for speaker protection is not a simple science. Loudspeakers fail from different mechanisms, over-heating and over excursion... Overheating involves heat input over time so is not a simple spot threshold but involves integration over time and knowledge of how fast the heat build up dissipates. Likewise excursion is not a simple spot voltage threshold but another different voltage and time calculation, not to mention interaction with cabinet tuning. A manufacturer may have some practical advice. There is always a trade-off that you may forgo some short term power output to insure longer term reliability. Sorry, nothing is simple in this area.
