Decks
There are many different kinds of decks one can have in their car ranging all different prices. There's your basic stock deck which is the deck that is originally placed in the car and there are after market decks. After market decks tend to have a lot more options and settings than stock decks do, such as sub woofer settings, equalizer settings, hpf settings, ipod capabilities, usb, and auxiliary inputs. And, they usually light up and look all fancy. The most expensive after market decks are touch screen and one can even go as far as storing music on them.
Speakers
When we start talking about speakers, there are 3 basic kinds. there's your tweeters, mids, and sub woofers.
Tweeters are very small but loud speakers that boost the high frequency aspects of your overall sound. They are very good at compensating for the overpowering low frequency sounds produced by sub woofers. They are essential to having a well balanced sound system in your car.
Mid speakers are your basic door speakers and their purpose is to boost the mid level frequencies of your sound. When used in combination with tweeters, you can produce a very well balanced sound within your car and your sound won't be too overpowered by the low frequency aspects of your sound which is produced by your sub woofers.
The other kind of speaker is your sub woofers. Sub woofers are designed only to be sensitive to all the low frequencies. They can be between 8 inches in diameter to even a big as 24 inches in diameter. The bigger the sub woofer, the more surface area on the cone which means the speaker can cover lower frequencies. Each sub woofer has an ohm impedance level(as does every speaker but its more important in relation to sub woofers), a peak power output and an RMS or root mean square wattage. The ohm impedance level is a way of measuring how sensitive the speaker is to the lowest frequencies. The lower the ohms, the lower the frequency of sound the sub woofer can cover. A sub woofer's peak power output is the most power a sub woofer can handle before the voice coil or surround is blown. The RMS(root mean square) wattage is how wattage the sub woofer can handle constantly before failing. The higher the RMS(root mean square and peak wattage, the more wattage you can send to a sub woofer. Many more expensive sub woofers will have 2 voice coils allowing you to throw even more power at them and allowing for the sub woofers to be sensitive to even lower frequencies. Sub woofers are usually powered by amplifiers that allow you to access more the sub woofer's full potential.
Amps
You usually want an amp that has a similar RMS wattage and peak power output as your sub woofer or higher so you can really put the sub woofer to work unless that is, you don't want so much bass in your car. In that case you would want an amp with lower RMS and peak wattage. Amps can range from anywhere to having 300 watt RMS to having 2000 watt RMS and even higher. One thing you always want to remember though is to check your amp's lowest ohm stability. If you have your sub woofers wired to 1 ohm impedance and your amp is not 1 ohm stable, you run the risk of blowing your amp. One other thing to keep in mind is to always have the gain knobs on your amp adjusted properly otherwise that could also blow your amp.

I thought that your article was well written, and contained a good amount of content for the subject matter. For someone who is more technically minded, this could be a helpful basic guide to car audio systems. The amount of detail is also good for certain subject matters. However, I did think that there was some room for improvement.
ReplyDeleteWhen considering your audience, this feels more like a technical guide to the basics of a car audio system, rather than a summary of car audio in general. Details such as Ohm Impedance and Amp Wattage are not things that the average person is very knowledgeable about. The title could be changed to reflect this, as I thought that just “Car Audio” may be a little too general. Either the content or the title could be changed to more accurately reflect what the article will tell the reader. Another point that could be changed is the actual details. While the article focused greatly on Sub-Woofers, it did not go into nearly as much detail regarding standard speakers and “tweeters”. It is my understanding that Sub-Woofers have more details that you have to pay attention to when selecting them, but for the average person, they may not need as much information on that particular part of the speaker system. Rather, they may want suggestions on standard speaker size or make for sound quality or volume range. These are just a few things I thought you may want to consider for revision.
First thing; keep in mind that the assignment was to write a Wikipedia-like article on a subject of your choice. There actually is a Wikipedia page on car audio, so perhaps you should use that as reference for your writing, as well as formatting.
ReplyDeleteWhile you provide excellent information, I couldn’t help but notice how much of your voice and opinion that you placed into your writing. It’s rather distracting, and makes your writing seem like a less credible source of information on the subject. Adding a “works cited” section could help make your work appear more credible. Try to keep your work strictly unbiased information.
I also noticed a few typos, as well as some strangely worded sentences. Many sentences in the second section of your writing need to have the first letter in the sentence capitalized, as well. Make sure to look over your writing again to correct any mistakes you could have made. One typo can ruin an entire paper’s credibility.
Your writing is all lumped together, making it harder to read. Perhaps if you put a bit of space between each part you talk about in each of your sections, it would be more appealing and less difficult to read. (Have one section about tweeters, one about sub woofers, etc.)
There are also a few, what appears to be, abbreviated words that people who are not familiar with this subject would not know or understand. Perhaps if you put parentheses after the abbreviation and inserted the full name of it or explained what it meant, it would help readers better understand your writing. Since you are giving the “basics” of car audio, isn’t your audience people who are unfamiliar with these terms? Make sure to think critically about who your audience is.
Hey Will!
ReplyDeleteYour post was informative, I didn't know very much about car audio and your writing taught me more about it. The format of your post is too dry though, so you should add some more information that isn't technical. Perhaps you could add the history of car audio, and what it is expected to be like in the future. I didn't understand a lot of the technical terms, but that's just me so of course don't take them out altogether, just add more facts that will be understandable to people less familiar with car audio. Adding this new knowledge will also make your post longer. The pictures supplement your paragraphs well, and it would also help to describe which brands are the best for each type of audio. With the information you currently have, it is not only too short, but the format reads like an owner's manual. Possibly, you should write your article to be a little less basic because I understand there is only a finite amount of information about car audio so you should delve more deeply into the topic to produce more readable/attention-grabbing paragraphs. You can also tell us more about tweeters and mids. Hope this helps!
Hello, Will.
ReplyDeleteI agree with Tsudoi in terms of the importance of audience in considering how you develop this text further in your revision. For example, some of your audience might be interested in car audio but might not be able to grasp the appropriate terminology. How could you adapt this?
