A question about bose speakers?




I do what


Do you think bose speakers are worth the extra & or not I have bose and others and i don't think the bose are that much better to spend the extra $ for them what do you think


Answer
Bose speakers are NOT worth the money: compared to what you can get for less.
Furthermore, u would be able to find many articles outlining their "corner cutting" manufacturing processes and also cheaper materials compared to it's competition at even less than half boses cost... Great example is: Audioengine, Klipsch, KRK, Polk, etc.

Just look at their products closely- materials+ overall sound quality: all you have to do is put one of their products side by side with one of the above competitor products and compare. Try it for yourself... And then post your botes here! I've done this - comparisons many times... And it'll be great to have others confirm my findings.

Other notes : include the fact that lol think they are worth the extra$ because Bose advertises:markets to the general public thru mass-marketing. Millions of $ is spent on advertising their name/products each year: forcing the average Joe to think Bose when they are in the market for audio. Bose marks up jacks up their prices so ppl think they are getting something special... Whereas the product sound quality and build quality is only mediocre.

Fact: Bose uses nO tweeters for most-most of their consumer line speakers: includes all soundocks(includes) soundock10, Bose radio, all companion series,all lifestyle/accoustimass series,musicmonitor,all v-series... These products range from $99-5000... And none of them have dedicated tweeters*... only 2"paper drivers: doing the job of the mid-woofers-at the same time!!! One would argue that paper is still a good material to use: fine, it is good- but Bose uses untreated paper... And small 2"untreated: and these little drivers do the job of midwoofers -u be the judge, all other manufacturers have gone metal/silk for tweeters...carbon fibers,metal,polymer, for midwoofers... And Bose stayed with untreated paper: which extends to their car audio: paper weathers badly in cars because of moisture,heat,cold etc.

Now let's say the paper/no tweeter part is not enough to qualify Bose as overpriced/cheaply made:... Then look at their "bass modules"... These things have only 5.5"paper woofers...their $4500 lifestyle48 system has a few of these small drivers for subwoofers... While every other brand uses at least 8" subs in their similarly priced systems... So ok, size is no bigg deal, and you done need the low rumbling bass... Then look at their subwoofer enclosures: LDF(low density fiberboard)... While every other decent audio company uses medium density fiberboard - Bose uses this LDF -ikea- furniture-grade- cheap-chipboard that is wrapped in veneer and plastic to cover it up... I don't care what the argument is: LdF is NOT AS GOOd as MDF... And is CHEAPLY made... And they are NOT worth the money they charge!!

Be careful when you are at the Bose store demos... Anyone can make a mediocre system sound decent - as their listening rooms are insulated and engineered for their systems+their recordings are MASTERED to make their systems sound great... Notice the narrator's voice is extremely chesty-nasally & raspy "s"sounds!!! It is all smoke and mirrors...

I've had a few of their systems and still have their car system... They are overrated, overpriced. And I'd say that they should be priced at 25%~ according to how they are made and how they sound(compared to other competitor systems).

Hope this helps

ps. Every question and answer is *relative*. If Bose were the only company in this business then they can charge whatever they want.. And without any reference point-comparison point-or relativity... Then they can charge $1,000,000 for their systems, and they'd be considered the market rate-but, luckily their (should be spelled "there") are other choices: competition law*will dictate the market value of any product and some will be expensive and overpriced(Bose):and some will be great deals(audioengine).

And like I said before- if anyone is listening... Sound is like color. perception of Color differs depending on
environment- ie: a room's lighting, ambience, will change how color is perceived... And furthermore, the human eye (like the ears) cannot "remember" a specific color very well; it is not until two colors are put side by side in the same room, same lighting conditions- that the human eye can tell the difference... And choose one that suits ones taste for whatever occasion.
Sound is no different. One can properly judge sound only if: the same file is played:in the same room:one after the other*~ otherwise... Anything can be staged: like Bose demos... Think about it- most of the Bose store/Bose displays are locked into playing their (mastered) files only. Like I sed, buy the Bose cra* and bring it home... Then buy some similar equipment from one
of the mentioned companies and compare side by side--- it is possible. If the Bose wins: and it is not too much more$$ or is within your budget (which I highly doubt-since I've done this numerous times:including their headphones...)--- then great!!! Good! U made an informed decision and purchase. But if the other product wins over the Bose; then great too!! You've made an informed decision+most likely saved some $$!!! Cool! Afterall, isn't this the reason y u asked theis question??

Motherboard speaker not working?




Matt


I just plugged in my motherboard speaker and it did not beep at all, then I took out the RAM and it still did not beep. I tried plugging it in backwards and forwards but it still did not beep. Could there be a problem other than the worst-case scenario, a faulty motherboard?


Answer
motherboard speaker or better known as 'internal speaker' or 'system speaker' (aka onboard speaker if it is on the motherboard itself, or casing speaker, if the speaker is attached to the computer casing) are no longer relevant nowadays..
some of the newer motherboards do not even bother to install system speakers because we have sound cards, better sound speakers and better technology than a speaker that is a remnant of the 1990's or 1980's..

but fair enough you did ask how to enable the 'system speaker'..
i think you better read the manual and the documentations that came with the motherboard.. on how to activate the system speaker (or any of its other names above)..
that's the definite answer..

but i can think of three general possibilities on how to solve the problem,
assuming that you have connected the speaker correctly and connectors were not loose or wrongly put..

one: go to BIOS setup page.. restart the computer, and press the 'del' or 'F1' or any key combination depending on the make of your motherboard..

in the BIOS setup page, search for anything that says: 'internal speaker' or 'system speaker' or 'onboard speaker' or 'casing speaker' or 'sound' or 'Beep' or 'Chirp'.. change anything related to those and switch it on..
and remember to save before you exit..

two: if you are using Windows.. go to the 'Device Manager'.. usually by clicking the 'My computer icon', select 'properties' and select 'Device Manager'.. or by searching for it in the Control Panel.. or by typing in the search "Device manager"..
in the Device Manager, click on the 'View' menu.. and choose 'Show hidden devices'..
expand the 'Non-plug and play drivers' by clicking the plus sign (or the small triangle icon (it varies depending on the version of windows)).. and double click on the 'Beep'..

within the Beep properties.. search in all the tabs for any reason for it to be silent.. for example if it is 'Disabled', flip it to 'Enabled'.. if it is in conflict with other devices, i am afraid there is not much that i can help you because the picture varies from one computer to another.. and if there is a volume control, make it louder (but do not set it to max yet)..

the third option require some of computer-know-how and you may need to send it to a workshop if you are not fully clear on how to do it..
Many motherboard manufacturers have jumpers on the motherboard that when jumped or not jumped will enable the speaker..
open your CPU and expose your motherboard and locate the internal speaker jumper..

Unfortunately all motherboards are different, therefore you will need to refer to the motherboard documentation in order to determine if your motherboard has such a jumper and what to set it to..

when i was younger assembling my own system.. i never bothered with the internal speakers.. because they are not as important as having a good sound card and a better sound system..

i usually leave the 'casing speaker' unplugged.. but that's your choice..

all the best

Which is better Retail or DIY Speakers?




Mikal


I am curious about other opinions regarding DIY loudspeakers. I'm looking to attempt to build speakers myself. Any suggestions?


Answer
It depends on who's designing and building the DIY speakers. If you know what you are doing you can easily exceed the performance of retail speaker systems.

Speaker manufacturers face a lot of limitations that the DIY'er doesn't face. For example, manufacturers are limited to their own technology or to technologies they have to pay for. The DIY'er can mix and match any known technology in any way he/she chooses. This opens the DIY speaker to the possibility of combining the best of all worlds.

In terms of cost, manufacturers have far more overhead than the DIY designer. In order to make money they have to cover the cost of materials, assembly, packaging, distribution... the list goes on. Typical retail markup is 1.8 to 2.0 x. so the manufacturer only gets $1000 to $1200 out of a $2000 retail speaker sale. To make money those speakers can not have more than about $150 ~ $200 in materials. If a DIY designer lacks the quantity discount on hardware he might have to pay double or triple for the same materials but he's still spending far short of the $2000 retail price the same retail speaker would cost him.

In the lower end market, it becomes more difficult for a DIY'er to save money but easier to exceed performance. Some of the OEM drivers used in low end retail speakers are not typically available to the DIY'er so basically he simply can't get crappy enough drivers to build something as bad as these. Sometimes such drivers are available through Parts Express Buyout deals so this gives the DIY'er the opportunity to get them and build some really cheap speakers with typical low end retail performance but for a cheaper price.

In the super speaker market the DIY'er can exceed the performance for a fraction of the sales tax of some retail speakers. When you get into the five and six digit price ranges quite frankly many of those manufacturers don't have a clue what they are doing when it comes to acoustics. In this price range "snob appeal" is the selling feature so the speakers don't have to be that good. This makes it easy for a highly experienced DIY designer to exceed the performance for a tiny fraction of the price. Especially in this area the technology limitations of manufacturers come in to play more than in any other market. There might be things they would like to do but they don't have the rights and they believe it is not good marketing to utilize technology from competing companies.

The DIY'er can of course have limitations too but that goes back to my first statement. It depends on who's designing and building the DIY speakers. There are those that have access to driver manufacturers with wholesale accounts to get drivers about as cheap as many retail speaker system manufacturers. They also have access to CNC and other manufacturing equipment just like the retail companies. In such a case the DIY'er doesn't have so many limitations. On the other hand if the DIY'er is limited to typical garage power tools the construction process can be more challenging. This doesn't mean it can't be done, it just means it's more difficult and may limit some choices. I definitely would not want to have manually cut the parts for my line arrays! That would have been a pain! The CNC made this chore a breeze.

Log onto the AVSForum and go to the DIY speaker section. Also take a look at the Parts Express web site and look at some of the projects they showcase there. It's a fun and rewarding hobby if you are willing to put fourth the effort to learn. I've been doing it about 35+ years and have fellow DIY friends that have been doing it much longer...one over 60 years.

Marine Speaker System Help?




Jordan And


I am making a speaker system for my jet ski consisting of:
2 70w speakers and cable
A 2 channel 200w amp
A separate battery (not sure what size i need yet)
A power on button
An Ipod and 3.5mm cable
I need help on what other components I need and what sort of wires I should buy (everything needs to be waterproof)
I am new to speaker wiring so excuse and stupid mistakes :)
Thanks



Answer
You can transfer the quality of your car or home audio system to your boat. Marine audio is a relatively new market, but many car stereo products can be bought and used on a boat. Some car audio manufacturers also offer specialized products for boats. for more instructions about speaker phone or for buying go through http://www.hifiguides.com/ ,
www.transcable.com/,
www.ecocables.co/, are some of the famous websites which provides all details through online with reasonable rate . Have a look on that.
