Distortion in Orb speakers
 
I have set up a new computer based system using an Asus G73SW into an Anedio Dac (via USB) into an Acurus amp and on to Orb2s. I am hearing hash (even at low levels) and particularly on choral music. Do I have damaged speakers? That is what it sounds like to me, but I am not accustomed to full range drivers. It is a harsh sound that follows the music but is volume independent. Any help would be appreciated. Thanks

um, you are listening to a pair of 3" drivers a side in a tiny enclosure without any baffle step. 3" drivers have around 30cm2 each while 4" drivers have around 57cm2. I'd expect a lack of midbass (under 500hz). But maybe one is run as baffle step, I don't know.

Seems people like them better in a 5.1 setup than stereo or 2.1

Run wide open sitting more than 5' away, yea, well, don't expect much. But run on a theater receiver crossing at 200hz, now you are getting somewhere.

Hash at low levels? what about solo voice ? You could have a rubbing voice coil (damage). A good way to check that is to lightly evenly press on the cone (meaning slowly push it in) and pull hand away. If you hear a scratching sound, then yea, the driver is damaged.

I not responsible if you damage to cone by touching it.

You have to make sure that the pressure exerted on the cone is symetrical. You could get a false scratch sound if not. Use an empty toilet paper roll to push with. Or something like that.

I also am not responcible for any damage that may occure if you accidentally use the speaker for toilet paper. Confusion sets in when troubleshooting sometimes.

I think the speakers were damaged by a small amp that was clipping and sending out either a square wave or DC. I cannot remove the grills so I am unable to test the drivers. I am expecting new speakers next week and these will go in the shot put category. Thanks for the response. Regards John Dozier

You can ohm them out with a multimeter

If they are damaged, their resistance readings will be different from each other by quite a bit.

i pulled out from a tv a pair of elliptic speakers , and when later i was listening to them ,they were polluting the sound . That never happened , I mean ,you can find inexpensive speakers that may sound acceptable ,and knowing their limits,they can serve the duty .
It's a matter of a very bad construction , lazy cones and magnets .
Now I use some elliptic speakers with a very little magnet (shielded) and simple pleated paper suspensions. Those are fantastic !!:rolleyes:
