Ok or not to use 5w30 in northeast Texas? : 432 * 406mm Sensitivity refers to the ability of a speaker to convert the electrical energy that comes to them into acoustical energy. Low voltage (1C LiPo or 3xAA) might also be a better match for your bluetooth receiver. This means that even if you have a 1000-watt amp, you can connect it into a 50-watt speaker as long as you do not increase the volume beyond what the speaker can handle. What is the point of Thrower's Bandolier? When you have a measurement of inches referring to a speaker it is the diameter of that speaker, so a 12" 400W speaker is physically 12" wide and is rated at a maximum of 400 Watts. Oil thats too thick can cause precious seconds to pass when little-to-no oil is available to lubricate parts, resulting in wear. Have an account? It's more fuel-efficient, has a quicker flow rate, and is better suited to colder areas. But as long as you don't "blast" the volume, you should be OK. You won't get 8W from a 9V battery. With such a speaker, you get 80dB when you power it with 1W and you measure at a distance of 1m. He played a bunch of bass-heavy dub reggae LPs, and the sound was truly spectacular. Always follow engine manufacturer recommendations. The higher the initial number, the thicker the oil is. * Samsung Galaxy S7 and later It can easily mean the difference between your engine going 100,000 or 200,000 miles, not to mention the high cost of repairs that come with increased wear and tear! Leo.. Powered by Discourse, best viewed with JavaScript enabled, Understanding ohm/watts in terms of speakers. "After the incident", I started to be more careful not to trip over things. If good sound doesn't matter, and it is a common amplifier, then 4 ohm is louder than 8 ohm. Notice the different numbers in the viscosity ratings: 5W and either 20 or 30. In order to understand that you first need to know that when operating normally, most amplifiers are "voltage limited", and like most electronics, they are "constant voltage"* devices. On the other hand, 10w-30 is a thicker multi-grade oil. There are 2 sets of numbers in 5W30 separated by a dash(-). Is it possible to create a concave light? My car is now 6 years old and at 205,000 km, it is like new. Apple Music Library Gone? What does the term quantization refer to? HINT,,, Don't bet against the JBL. PA speakers are often louder than this. What is the difference of having one speaker per output vs many speakers on one output, Identify those arcade games from a 1983 Brazilian music video, Replacing broken pins/legs on a DIP IC package. If you're unsure about how much or little power your speakers need, check with the manufacturer. purchase from Musician's Friend (electric or acoustic, New or Open Box) includes two years of Less sensitive or less efficient speakers could have a high wattage and still produce low volume and distorted sound. However, when or where you plan on using the charger, may also play a role in what output is most efficient. http://www.soundz.co.za/c792-1/Powered-Speakers.aspx, How Intuit democratizes AI development across teams through reusability. Both tubes with the steel ball were refrigerated at -18C for half an hour. Then your device will be placed on the charger for a couple of hours, so charging speed is not relevant. -f ? The specifications are: The frequency response shows the range of frequencies the speaker can produced. More, Popular It may be used at temperatures ranging from -31F to 95F / -35C to +35C (outside temperature). However, the problem with thicker oil is that the oils resistance to flow is high. Many systems require the motor oil to flow through tiny solenoid openings to actuate VVT components. Even with all these factors, anyone who holds parties and events at home or away needs more wattage. For example, Samsung Fast Charge works at 9W whereas Apple Fast Charge is optimized at 7.5W. Generally, it is best to choose the charger with an output at least equal to what is supported by your device. To be honest though, i doubt that the difference would be detectable between a 10 inch and a 12 inch though - to hear an audible difference one would have to compare a 8 inch with a 15 inch for example Thats just my 2cents. Power handling specifications, meaning how much power is safe to use with a speaker are a completely different issue, unrelated to speaker sensitivity. Label on speaker reads "120W(MUSIC), 60W(DIN)." Usually, the answer is yes. W stands for winter, for example in 5W30, the lubricant has SAE 5 viscosity when cold and SAE 30 viscosity when the engine is running. Most people will find 20 watts enough. Oil thickness: why it is important No wiring changes to the speaker circuits are required. Or, if you use an 8W amp with a 3W speaker and play it a full volume, you could burn-out the speaker. Speaker 1 U, Charging cable 1U, User manual 1U Looking for specific info? In this case a standard 5W charger will be more than enough to do the job, even if your phone supports a higher output and/or fast wireless charging. The W means winter and 5W relates to how the oil performs when it is cool. Spectrum Internet Keeps Dropping: Quick Fix In Minutes! The dimension of inches more than likely relates to the smallest dimension of the speaker enclosure and basically if you want more power, you need something that is bigger. But thicker isnt always better; oil thats too thick can result in oil starvation. The 5W-20, however, will remain a little thinner once you reach operating temperature to help improve fuel economy and flow fast enough to fill the tight tolerances in the engine. Please rotate your device for full experience. I understand that inches are size of the speaker, what I want to understand, how is it connected to Watts, for example, 15" 500W Sub vs. 18" 500W sub, In terms of sound, how do these speakers differ? I'm not sure what you are trying to say, but if an amplifier is designed to work at 4 Ohms, there is no quality loss at 4 Ohms. For Samsung* you need a wireless charger that supports Samsung Fast Charge, and if you have an iPhone** make sure to look for a charger that supports Apple Fast Charge. 25, 50, 100 or more watts, or maybe a lot less; the Audiophiliac ponders the wattage question. About 3 decibels lower. From the above example, you see that it takes so much power, wattage, to double the perceived loudness of a speaker. Free Standard Ground shipping (48 contiguous states, some overweight and Used/Vintage items excluded). Which smartphone you have and how you intent to use the charger are also important aspects to consider. The ChiCom speaker will require several hundred watts to run with that particular JBL,,,And will fry far before it ever gets there. . To keep your speaker safe, ensure that the amplifier is the same wattage as the speaker. That's a win-win in our book!When possible, The Gadget Buyer uses affiliate links (at no additional cost to you). The 5w and 10w in their names are ratings that refer to their low-temperature behavior, while the last digits . In an unscientific evaluation, I once swapped a V30/G12H30 combo for a Governor/Wizard combo and my amp settings remained the same for band practice, so even if there was a difference, it was negligible. The best wattage for the home speaker is between 15 and 30 watts. With an undergraduate degree in Computer Information Systems and marketing paired with a Master's in Business Administration, Kern brings a unique blend of technical expertise, business acumen, and personal experience to his writing. It also doesnt state how long the speaker sustains the power and with which materials. Different outputs: 5W vs 10W vs 15W. The Sound Pressure Level, SPL, indicates the loudness of a speaker. Or after 10K KMs. Both the inches and the Watts are suggestive specifications of the following: The reason these are suggestive, is that they don't really tell us the important figures - they just suggest what these may be. Even as you consider wattage, consider other factors such as durability, form factor, affordability, and sensitivity of a speaker. Thanks. This is more than what the first speaker generated with 10 watts. What is the difference? There are different authorities that set the standards for speaker power handling rating. Edit: A note about sensitivity. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. That is usually 100C (212F) when the engine is running (in an average engine). Then you mix in speaker sensitivity and there's really no point in thinking about it. The highest sensitivity 12" guitar speaker can be 101dB or so and the lowest around 95dB. If you listen to audio at moderate sound, you do not need to worry about the power rating of your speaker. Often we say that a speaker has "flat" frequency response within a specific range, where "flat" means a certain error is allowed (3dB, for instance). Little tidbit: watts is another way of saying joules per second. That's why I created TheGadgetBuyer.com to help you pick just the right gadget for your needs! The better quality the oil (i.e. Comment * document.getElementById("comment").setAttribute( "id", "a52b9f9d62231238f7d7aab4597ad98e" );document.getElementById("d1d327f8af").setAttribute( "id", "comment" ); Save my name, email, and website in this browser for the next time I comment. Then we'll look at 5W-30 vs 10W-30. Other manufacturers may also refer to the diameter of the bass driver. For instance a peak measurement will be higher than an RMS one; it is common practice to show Max SPL in peak, but RMS correlates to our loudness perception more than peak. For a deep dive on what happens if you use the wrong viscosity of oil, check out this post. You must log in or register to reply here. Read the above article. But, you'll get some "drop" through the amplifier so you won't get the full voltage, and the 9V battery can't supply that much power (voltage and current at the same time) and you'd be lucky to get 1W. The lubricant must reach all parts of the engine right away. Are you following manufacturer recommendations? 5W is a synthetic lubricant having better oxidation resistance and longer drain intervals. The 5w30 motor oil is thinner than the 10w40 motor oil. So I'm almost finished working on a project of making a bluetooth speaker/amp. See this link for more. Why proper charging solutions are essential in hotels, restaurants and bars. But, an AC waveform only hits the peaks for an instant, and the RMS (a kind of average) is about .707 times the peak. Less efficient speakers have a lower number. The number before W (5W-XX and 10W-XX) tells the SAE viscosity of the oil when it is cold. Ask for FREE. If you cut the impedance in half, you get twice the power. So, a 3W amp (at full undistorted volume) is putting-out about 0.3W average and the speaker can handle that. Some manufacturers do not follow the standard and rate speakers based on an informed guess. But cold to your engine is anything below operating temperature, even if its 80F (27C) outside. I am by no means an expert, and have only just started "looking into" sound, having to "size" a system for my new car (previous car was bought with sound already installed) anyway, from what i understand (having spoken with 2 friends who installs sound for a living) is that all things being equal (i.e: same brand, same RMS watts) with the only difference being cone size (10 inch vs 12 inch for example), you will find that the 12 inch is less responsive. It is a recommended lubricant along with 15W40 by the engine manufacturer, even though I am driving in a hot climate in the gulf region. But 10w40 oils have an added advantage; they typically offer more protection than lighter oils. What an awesome answer,Thank You, the picture just got more clearer. Lets look at 5W-20 vs 5W-30 first. In modern car engines, we need the oil to be thinner at the time of startup. Most experts agree that 80% of engine wear occurs during startup (warming-up) the engine. The first number (5W) refers to the oil's viscosity when cold, measured at 40C (104F). Home > Blog > Which wireless charger is best for my smartphone? Same goes for 10w30 multi-grade oil. Also - i know there is allot more to be said on the subject if one delves deep into the differences, this is just an oversimplified view by a novice (me) to try and make sense of a subject that has quite a steep learning curve. What I can say is that for any given speaker, if you double the power into it you get about 30% more perceived loudness. Ten times the power means doubling SPL. @Stoan: it's just a made-up example. P = V2/Impedance (This one is handy for amplifiers & speakers.) But how do you find the right wireless charger for your devices? Connect and share knowledge within a single location that is structured and easy to search. Which wireless charger is best for my smartphone?

Hello my name is Michael I have a question I have a 2004 silverado Z71 Im using Castrol 10w40 high mileage because I have 265.000 can i go back using 5w30 Castrol Edge full Synthetic, This oil is very helpful to engine work smooth. The higher the number, the greater the oils resistance to flow and the higher its viscosity. The efficiency of a speaker, the number of speakers connected to an amplifier, and distance of the speakers from each other affect the loudness and quality of sound. 5W30 and 10W30 lubricants have the same viscosity at the operating temperature of the engine. We need the oil to be thinner at the time of starting the engine. The number 30 in both 5W-30 and 10W-30 indicates the SAE viscosity at 100C (212F). If you are looking for 5W, it is better to use 5W-40. The challenging issue with speaker wattage is that it lacks a specific definition. OK However, an oil with a lower viscosity at operating temperature reduces internal friction, which maximizes fuel economy. Also, manufacturers may perform tests using a half-space setup (speaker close to one wall), which will increase the figure by approximately 3dB; so unless the full test specifications are mentioned, it's hard to tell the exact performance or to compare it. It may not be. As per API recommendations (1) for car engines, you can use 10W30 oil if the maximum expected outside temperature is above -18C (0F). 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. Higher or thicker viscosity motor oil has a better seal compared to lower viscosity oil. I am using5W40for my car instead of15W40. The physical size is very closely related to the sound, for example to get a good bass response you need to be able to physically move a lot of air - so the only way to do this is with a large speaker. A steel ball moving from top to bottom indicates the thickness or viscosity of the oil.
