Full spectrum pink noise?? Running in speakers?!
Question: Alrite sound fellas, help me out if u can.
I bought 2x PA-1220 Accusound (australian brand) Professional Speakers. 400w RMS 800w Peak
2x 12" Subs and 1x Horn in each speaker.
In the manual it says i must "run in the speakers for 30 hrs" and "this is best done with playing full spectrum pink noise"
Now, i looked around online and found a pink noise sample.
Are all samples full spectrum? (Because when i play it, it sounds like tv static, and my winamp equaliser, ALL the bars go up) So im guessing thats full spectrum?
Then in the manual it says "Or you can play music with good lows and highs"
Whats the best route?
Any thoughts on the subject?

Interesting... I've never actually read of a manufacturer telling a consumer to do this.
So what they want you to do is break the speakers in... to warm them up, to kind've work them over a little bit. You do this by running a signal through them that has a wide variety of sounds (both highs and lows). This can either be energetic music that you might normally play through them or running some type of noise.
Pink noise isn't actually full-spectrum, technically. White noise is full-spectrum - noise with an equal amount of energy in each octave. Pink noise is more like white noise with a gradual low-pass filter applied to it.... sometimes it's referred to as 1/x noise. Pink noise is much more natural, it sounds like waves or the wind instead of radio static. I wouldn't see a musical benefit in playing white noise through your speakers vs pink noise. In fact, white noise would piss you and your neighbours off a lot quicker, which is probably why they suggest pink noise. =) If the sample you have doesn't sound more like a wave or wind than tv static, get a new sample. It shouldn't sound all that harsh. I've included a link below to a pink noise generator. Check it out!
Anyways, if you want to warm up your speakers, I would see no problem doing either, but if I was going to try to do it properly, I would do it half and half... 15 hours of pink noise and another 15-25 hours of a wide variety of music with both highs and lows (dance, techno, death metal, hip hop, punk, etc).
When you are doing this, pay attention to your volume. Don't hit your speakers with peak volume right from the beginning - keep your volume a little lower than you expect to play them at normally for the first few hours, then raise it to your expected normal listening volume for the bulk of the rest of the hours, but then raise it a little above that for a few hours after that as well. Does that make sense? Noise -> Music, volume low -> normal -> high? Don't push your speakers too hard during the warm up phase, don't go into your peak volumes before they've warmed up.
After your warm up phase, your speakers shouldn't have a problem handling a wide variety of highs and lows. I would definitely run a few minutes of program material or pink noise before you intend to run your speakers hard.
Read a link I found... it's about car stereo equipment, but there's some good information that can be applied to your speakers as well. You might find something that can apply to you and your question.
Good luck!
