Is there an easy way to check for polarity in speakers?

I have two speakers that are outside that are wired for a wall plate inside. The wires are not marked at all, save for L and R for individual speakers (easy test) and electrical tape to mark the negative at the speaker. :psyduck: I am guessing they ran the wires from the plate to outside and marked the wire to hook the speaker up from there. But now the plate is gone, replaced by a cover and dangling wires behind it. I don't really want to run new wires.

Connect a AA battery to the speakers. If the cone moves -out- then the terminal connected to the battery + is also the speaker +

1.5v isn't enough to damage to anything larger than a headphone driver, but obvious don't leave connected longer than a quick excursion.

Hey I've got a question for you guys:

I have this old stereo system that's broken - cd's dont work in the cd player.

What sucks is the speakers are practically intact, and I don't want them to go to waste.
So I was thinking of connecting them to my computer's surround sound system...
Problem is the connections are not compatable - my computer can recieve either RCA or regular headphone jacks, but the speaker's output cables are red and black wires.
(they fit into the negative and positive terminals in the back of the stereo shown here: )

I considered cutting open some headphones and splicing the wires together, but it won't work for a couple of reasons (there's probably a danger of overdrawing current).

So my question is if there's anyway I can connect the two wires to a RCA or headphone jack input?

Here's a question: is there any sort of (windows) application to isolate sounds by the application they are coming from, and output them to different channels? (ie, iTunes coming from left channel only and firefox coming from the right) or maybe even separate audio by what monitor the application is active on. That would be very cool.

I have a set of Z5500 Logitech speakers that are admittedly a few years old now but I always took immaculate care of them. Recently, I had them in storage for two years (and they worked perfectly prior to storage) but now I am having trouble getting them to work with my PC setup.

When I turn the power on at the console unit, everything appears to be as normal, except the subwoofer emits a non-stop low hum that cannot have it's pitch or volume changed by any settings (either in Windows or on the console unit). None of the speakers emit any kind of sound and fail to react to any of the default tests that Windows and Logitech provide to check your individual speakers.

Wondering if anyone has some advice to save me spending a few hundred on new speakers? I'm no genius when it comes to this sort of thing.

Sounds like you have a ground loop. Try plugging the power for the logitechs into a different power circuit and see if the hum goes away

It's difficult to imagine a situation where a ground loop affects the sub but not the other speakers powered by it. If that were the case, it would indicate a problem internally with the sub, not anything you could fix by changing circuits.

If I understand right, there's a buzz coming out of the sub and you get nothing at all coming out of the satellites (even when you're supposed to)? That could be anything from the input cable/jack on/to the console unit, the cable/jack from the console to the sub, or a host of things internal to the sub. If there's an electronics repair place you could probably bring the sub, console and one satellite in and I doubt it would be very expensive or difficult for them to find exactly where the problem is.

Undoubtedly a stupid stupid question, so be gentle....

Amazon is selling a well reviewed Denon receiver (AVR-3310CI) for a great price. I'm also looking at Magnepan MMG-Ws for my front and rears in a home theater. The speakers are listed as five ohm speakers, and the review for the Denon at hometheaterhifi.com says to not even try using it with four ohm speakers. Does that rule it out for the Magnepans I'm looking at?

A quick look at the Denon specs indicates a 6-16ohm rating, and the Magnepans rated at 5ohm are notoriously power hungry. You could always utilize the pre-outs from the Denon into some outboard amp(s). But otherwise I don't think it would be wise to try and push Magnepans in surround with just the onboard amps.

I'm thinking about getting a surround sound system (not an HTIB.) I've scoped out an Onkyo receiver to buy, but I'm stuck at a pretty stupid / quick question.

The layout of the room is such that I need front speakers to be bookshelf speakers (can't be on the floor because of kids), and the rears to be floor standing. Is this ridiculous or can I buy 2 floor standing (let's say Polk Audio TSi300s) and two bookshelf (2 TSi200s)? What I do know is I'd like to match the speakers from the same line / company. Any thoughts?

That seems kind of silly to me, considering how much more work the front speakers do. In my opinion, you'd probably be better off just getting all bookshelf speakers and getting stands for the rears. Unless there's some reason I'm not considering that would prevent you from using speaker stands.

Well the only reason not to get speaker stands is because they are lighter than floorstanding speakers which means that if they kids do manage to get at them, then they can knock them over more easily.

Ah, I see. I'm obviously not a parent (I think I'd be too paranoid about my kids AND my audio stuff). Maybe some wall mounts could work in your situation? Those 300s are 26 lbs each, which doesn't sound that hard to tip over depending on the age of your kids. If you can find some heavy stands the bookshelves might end up being more stable anyhow. Some stands allow you to pour buckshot or sand into the base to increase stability.

Audio-wise, you won't mess anything up by going with the big surround speakers. Your receiver should allow you to adjust the rears to more closely match the fronts (I don't have any experience with those particular speakers, but I'm assuming the towers will have better/more accurate bass). Basically you just might be holding the towers back a bit by not letting them use their full potential, but if you don't have a perfect room for audio (and who does?) you have to work with what you have :).

I have a Sony STR-DE585 tuner/amp and would like to listen to the radio. When I try FM radio, it has this loud buzzing/humming noise that completely obscures the radio channels. Thus far I've ruled out antenna, location and cables. Amp works perfectly fine when listening to CD music. Quick opening didn't reveal any burned transistors or exposed wiring. Nothing touches the amp casing as far as I can see.

Any ideas how I could get the humming to go away?

24 AWG might be a little thin for a 60' run. I would certainly not go any thinner gauge.

Tabulated below are the recommended cable distances (+20%) one should use for various speaker cable gauges and speaker loads.

pre:
Speaker Impedance   8 Ohm Load    4 Ohm Load
   Wire Gauge      Distance (ft) Distance (ft)
      18 AWG	      10                5

However, this doesn't work with my cable box or 360 (both connected to the tv via HDMI), which both support 5.1. Is there some kind of setting that I am missing to make this work, or is the PS3 one of the few devices that support something like this?

That's very strange, I'd expect it to be all or nothing. Most TVs don't support passing audio from HDMI to optical at all

Only thing to check is whether your PS3 versus the cable/xbox are sending LPCM or SPDIF (DD/DTS bitstream). Usually this is a setting you have to adjust in the respective devices. Whatever setting you have on your PS3 is apparently what your TV supports

What make and model TV do you have?

I do this technique called a suplex. You probably haven't heard of it, it's pretty obscure.
I'm interested in a wireless audio solution. I like to watch TV when I'm doing the dishes or other mundane tasks, but I have to crank the sounds way up to hear it over the water (or whatever else I'm doing), so I'd rather avoid just turning up the speakers all the time. I've tried using headphones with a long cord, but it's inevitably a hassle because it gets tangled up on things and I sometimes do my best to yank my laptop right off the table. It seems like an ideal solution to this is wireless. What sort of solution is best for this? It seems like I could do it with bluetooth headphones and a bluetooth transmitter with a plugin of the same type as normal headphones. I don't want to spend crazy money on this and am not overly concerned with quality, I'm pretty far away from an audiophile. I'm also not stuck on the bluetooth idea if there's something better out there.

I just purchased a 7.1 surround sound system and I'm trying to figure out the best place to put the speakers because my room is in an L shape and my tv is in a corner.



The TV the solid line and I'm primarily going to sit at X.


The manual for my surround sound system says that generally the subwoofer can be installed in a front corner or one-third the way along the wall. These examples though show the tv centered flat against a wall.

Should I just put the subwoofer flat against the wall or should I point it more at where I'm sitting or does it really not make a huge difference?

That room is an acoustic nightmare, but you do what you can with what you got.

2 speakers behind, 2 to the side, 3 up front, and your sub out of the corner. Bass is mostly non-directional, you're supposed to feel it more than here it, so if you tuck it behind the TV it'll likely be boomy. Try a few places around the room, see what you like best.

I'm going to Roskilde Festival next Saturday and it's probably too late to start building my own sound system (unless some people here could point me to an easy how-to guide), so my camp has decided to purchase one of these: http://www.ionaudio.com/blockrocker

Now, the only problem is having to recharge it ever so often. Would it be possible to hook up a car battery and a solar cell system to it so it could run a longer time without us having to recharge it? I know the plug is for charging it like you would with a regular speaker system or whatever, but surely it should be possible to do something like this?

Oh, and if this isn't the right place to ask, please point me in the right direction :) .

If you hook a speaker up backwards it will sound very hollow, tinny and have no bass. if you hear that, then you can just flip the wires.

Generally, however, the cabling should have one wire marked with a solid stripe down the side or something to indicate the negative wire.

Generally, however, the cabling should have one wire marked with a solid stripe down the side or something to indicate the negative wire.

That hollow sound is the effect of phase cancellation. In simple terms, two speakers creating opposite vibrations.

If there's only one speaker, polarity doesn't matter. If there are two and one is out of phase, flipping either speaker will solve any polarity issue.

Multichannel setups, however, can be incredibly difficult to "guess" into phase. That's why the polarity checking in the automatic setup routines that modern receivers have is so helpful. Still, you're better off paying attention to wire markings.
