Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Therefore, drivers who live in colder climates or those prone to near or below freezing temperatures during the winter months, are advised to use a thin grade oil (e.g. As noted earlier, it represents the thickness of the oil and its resistance to flow. Or, if you use an 8W amp with a 3W speaker and play it a full volume, you could burn-out the speaker. Given in dBSPL, typically at 1 meter away from the speaker, this is an indicator of how loud the speaker can get. To understand this correctly 8ohms has more impedance thus lower wattage That's generally correct. Different outputs: 5W vs 10W vs 15W. Ultimately, choosing the right viscosity is a balancing act between competing priorities. Those speakers are extremely sensitive, they're rated at 101dB @ 2.83V, so they can play stupid-loud with a handful of watts. stream The number before W (5W-XX and 10W-XX) tells the SAE viscosity of the oil when it is cold.

How much is enough? 10w30 oil is thicker than 5w30 oil because it has a higher viscosity in colder temperatures. For instance, when the loudness of a speaker increases from 40dB to 80dB, the decibels will have doubled, but the perceived sound will be way much more. According to API motor oil guide [1], you can use the 10w30 if the lowest expected outdoor temperature is above -18C and you are following the manufacturers recommendations. To understand this correctly 8ohms has more impedance thus lower wattage, less decibel range than the 4ohm 3 watts? 2" is actually pretty big for a tweeter, for instance the Mackie 300z has a 12" for the midrange and 1.75" compression tweeter. How quickly or slowly motor oil flows affects how well it protects your engine. As you still seem to wonder about differences in sound between different speaker sizes: The speaker diameter is not directly related to how much bass you can get. In such cases, only one watt powers a speaker. The W means winter and 5W relates to how the oil performs when it is cool. (you must follow the manufacturers recommendations). It may not display this or other websites correctly. See how AMSOIL products perform in the lab and in the field. Answer (1 of 6): Strictly answering on the acoustical power and perceived loudness: you can't hear the difference. So, the thicker the oil, the more resistance it has and the slower it flows. Oil thats too thick to flow through these openings can cause problems and trigger a check-engine light. Linear Algebra - Linear transformation question. These new "500W" (which is almost always peak and not RMS values) require a 10KW diesel generator to drive them where the efficient speakers an be bone crushing at 50 watts.
