So, I’ve been thinking about doing something like this for a while now. I’ve made a set of studio monitors. I used a set os plate speakers made by Infinity. The specs on these are quite the opposite in what I prefer in car audio, but my friend gave me these for helping him work on his car. The basic rundown is the woofer cone is an aluminum inverted dust cap cone, tweeters are silk. Enclosures are 0.299 Cubes, sealed, 1/2inch MDF. Here’s some photos.
This is my first set ever, as far as home equipment goes. These are hooked up right now in the living room to the reciever that does the sound for the TV(curb your enthusiasm is no the screen before you ask, love that show). They are sitting on top of the speakesr i usually use, temporarily. I told my dad to do some extensive “research” on them by watching lots of TV and playing with the volume and such. Dont you guys wish you were my family, where I would put you to work doing things like that? Make sure my food tastes nice and my big screen TV looks good and my equipemnt sounds nice too? heheh Anyways. This is the very first set I’ve made from just stuff I had sitting around. Next step is to wrap them in something to make them look more appropriate. Any suggestions? Later on i want to hook them up to my computer and do more extensive testing with movies, LOTS of music and games. So far the first impressions are promising. I wanted to end up with a set of speakers that sounded as flat as possible and these are doing it. They really dont overemphasize or mute anything in the range and sound very soft, so listening to these for 10+ hrs shouldnt fatigue my ears. I may end up giving these away or selling them to somebody for a very low nominal price after Im done with them. I plan to keep making sets further and further, improving on the next step as I make more. I did not want to commit too much time or cash to my very first test build. As you can tell, I do not have any fancy woodworking equipment. Holes were cut with a lateral bit, the plates were cut with a simple circular saw. I didnt round off any of the outside edges. This is as simple as it goes. I am considering making a nice center channel for my TV sound system. I really like copper drivers. My friend has a gorgeous sounding set of Klipsch copper drivers in his center speaker in the setup in his living room and I want to buy some drivers just like that and find a great enclosure design and get to working again. Comments, suggestions, criticism and ideas are much appreciated. :thumbup
They do, and yes, car audio is usable in home builds. I’ve seen numerous people do it and have heard several setups where they used all car audio, deck and amps and just a voltage onverter and it sounded great. it’s really not about if its made for home or car, its more about finding the speakers with cetrain specs that you want and making enclosures to spec for them so they work as intended. it’s easier to do at home because the surfaces and rooms tend to be much more regular as compared to car interiors.
Audio signals are AC regardless of home/mobile setups. Just be cautious about the impedance/resistance of the speakers; home is usually 8 Ohms, mobile is usually 4 Ohms.
my friend suggested to make silver carbon fiber face plates. i have a sheet of that stuff sitting around. im thinking either spraying them flat black or wrapping them in black carpet.
u sure? i know the sockets are AC(we’ve plugged in subs to kill them into outlets directly), but i think the output OUT of a reciever in a speaker connection is DC. have you seen the amount of capacitors they cram into recievers?
House AC sockets are 120V 60Hz, say into a 4Ohm sub… that’s 30Amps… about 3600Watts. Most subs don’t like that :lol
The caps in an amp are for the power supply.
I dont have much time to go into why audio is AC, I actually have a lot to do today at work. Google it or better yet take a 9V battery and connect a speaker to it :lol
I had a pair of 8’'s that did a 140 in my old cavy.
When I went away to oneonta for school, I brought them with me. I had them in a ported box, corner loaded them, powered them with a zapco ag350, had a car aduio battery and battery charger. Then I had 2 cabinets with a 12’’, 6’’ and 2’’ tweeter in them. Used a pioneer headunit, and had my computer as the aux in.
Needless to say, I was TOLD that I needed to bring it home and never bring it back. Something like 3 complaints (only 1 for me, other 2 was my roommate) in 19hrs. I maxed out my radio shack db meter at 126db in the middle of the room
HAHAHAH, i remember that! that would have been awesome to hear in person. I really want to build something absurd involving sonotubes in the basement very roon
A battery will just make the speaker cone move out or in, depends on how its connected. Once connected though, the cone will only move once, not sounds will be produced.
> Essentially, the [amplifier](http://www.howstuffworks.com/amplifier.htm) is constantly switching the electrical signal, fluctuating between a positive charge and a negative charge on the red wire. Since electrons always flow in the same direction between positively charged particles and negatively charged particles, the current going through the speaker moves one way and then reverses and flows the other way. This alternating current causes the polar orientation of the electromagnet to reverse itself many times a second.
im totally thinking backwards :crazy:crazy haha, fucking sinus infection. anyways, guys what do you think if i wrap these in black carpeting and do the faceplate in silver cf?
