What is omhs and hz

[Toli Chamos]

A total noob to audio and everything pc. Please help. ohms*

 

[ski2xblack]

Ohms are a unit of measure of electrical resistance (in dc circuits), or impedance (in ac circuits).

Hertz (hz) equates to cycles per second, or frequency.

I understand what hertz means but what does it have anything to do with sound?

 

[lovinthehd]

Sound reproduction generally is aimed at a range of 20Hz to 20,000 Hz, generally the limits of human hearing.

Hertz refers to the number of vibrations per second. The low B string on a bass guitar vibrates around 41Hz, or 41 cycles per second. The A above middle C on a piano plays at 440Hz. As the frequency (or Hz) doubles, you go up exactly one octave. 880Hz is one octave above 440. And when it's halved, you go down exactly one octave. 220Hz is the A below middle C on the piano. The fundamental notes of human voices range from about 60Hz (James Earl Jones) to ~2kHz (Mariah Carey). Breath sounds, sibilance, plosives, fricatives, and all the other neat consonant sounds we give words often occur above, around 7 to 8kHz, much higher pitch than we can vocalize. And of course there are crash cymbals and high hats, organ pipes and concert bass drums, synthesizers and explosions, and countless other reasons to be able to reproduce more than just the vocal range.

The 20Hz - 20kHz range lovinthehd mentioned varies from person to person. I can hear below 20Hz, but can't hear above 14.5kHz or so to save my life regardless of the volume.

Toli,
Have you considered spending part of your educational grant on a book?
I suggest "Google for Dummies".

Just kidding.

hahahahah good one. I googled it and the answers were to complex for a noob like me to understand.

?? Basic definitions are merely the foundations of understanding. For true understanding, you have a heck of a lot more to learn than merely the definitions of hertz and ohms.

What is your goal? Do you want to know how all this stuff works, or is your goal simply to be an informed consumer because you've come into some disposable cash and want to avoid expensive mistakes? We can help direct you in either case.

I want a stereo speaker setup 2.0 (I would get 2.1 but l have nowhere to place the sub woofer). I have a small room and will use the speakers for music and gaming. Could you give me a full list of everything l need to buy? Budget is $600

You put your response into the quote, somehow.

Start with just what measurements the room has, where in the room will you put speakers, how far away from them will you sit, and how loud do you like your music (compare it to normal speaking levels to "cant hear my buddy talking to me face to face in a nightclub."

And what sources do you have for the music you want to play? Do you have a CD player, turntable, or just streaming from a computer?

For more on the relationship between acoustic frequencies and music see this. Don't overlook the part below the piano keyboard.

Small room, computer setup, near-field listening...some sort of active monitor would fit the bill. There are quite a few options to choose from but here are some ideas:

You can get THESE at Amazon for $450. They're self powered, fully self contained (you don't need anything else), they provide a plethora of inputs, remote control.

Similar price range would be THESE. Also pretty much self contained, and those bamboo cabs! (Don't buy on looks...of the three options I've linked to, these may be the cutest, but as far as sound, they would be in third place, behind the JBLs and Klipsch.)

Now, if you're willing to add a bit more complexity to your system (while still staying in the same budget), you can consider the active monitors from the pro-audio side. For example, a pair of JBL lsr305 can be had for $300, which is a lot of quality sound for the money.

That interactive chart is pretty cool. Check it out, Toli.

I would take the Audioengine A5's over the Klipsch any day of the week. Not that the Klipsch are bad, they're actually quite good. It's just that the A5's are about as good but have nicer fit & finish and more choices compared to the R-15PM's black vinyl laminate.

If you like the look of the copper colored driver though....

What dac and amp would you recommend with those speakers? Also How do l check what cables l need and will the cables come with the parts?

 

[KenM10759]

The speakers are powered speakers therefore have the amplifier built in. As long as you don't need ear-splitting volume at 20 feet away, they're fine. The Audioengine A5's come with the cables you need to plug them into AC power (your wall outlet) and to each other. You do need to feed an analog signal, but not knowing what your source material (music) is coming from I don't know what you may need. If it's just output from a computer you just need a 3.5mm stereo output cord and that's included. So is an "RCA" interconnect cord, which is the standard analog stereo output from a receiver.
