With regard to speakers it is no easier to offer out a precise measurement for you as a consumer to make selections. Speaker power “handling” varies as a function of so many things – the level of distortion present in the signal, the physical installation of the speaker, the environment around the speaker and of course the crossover settings filtering the input to the speaker.
So that it is clear – our RMS ratings are designed to give an indication of the maximum “burp” value that we feel comfortable feeding through them in perfect conditions. By this, we mean that for the ratings to be valid the system crossovers and subsonic filtering need to be appropriate and the physical installation be such that the speaker baffle is working properly. We also assume that you are feeding clean power into the drivers – ie with a THD of 1% or less. Note that you’ll need to have a keen ear to hear much less than about 3% THD so that means to all intents and purposes we really do mean CLEAN power. DC wrecks speakers. Quickly. And without mercy. We see a lot. And it’s never YOUR fault apparently...
Also it is important to note that we are giving you a guideline to the maximum you will want to run for a demo track, or “contest” style speaker burp. Our speaker RMS ratings are NOT “play all day” continuous ratings. Heat management is the responsibility of the installer – ultimately a happy continuous rating would still adhere to all of the above caveats but would perhaps be 50% to 75% of the burp value depending on the exact speaker and exact circumstance.
There is a huge difference in the way that people use car audio. Some people want to compete in competitions that push the equipment upto and beyond its limits. Some people want their investment to last 10 years and simply use their system for personal enjoyment at modest volume levels. We ask you for some common sense – you cannot be one of the former users and expect the same longevity as the latter. Therefore, when we rate our products we are faced with an immediate compromise since there is infinite variation in circumstances.
We are working hard to produce spare parts for our speakers, so that our customers can service burned out speakers and keep hard working systems running for lower costs. We urge you to view the soft-parts of your speakers almost as a consumable. They will not last forever, and, depending on how hard you make them work you will enjoy a shorter or longer service life.
