Test tone playing...question

[MisterGrubbs 5,000+ posts]

All right I know with songs you can download for bass - some of them say "caution may damage speaker" ... err question - how much do I need to worry about these warnings, so to speak?

Is it all right to still play at high volumes, or should I stray from doing this?

Same question about test tones...

Gets the coils hot, really works the speaker suspention, your ears and common sense will tell you when to back off.

10-4 on that

What if I just try to show off a little too much? Buying a new speaker? lol

I havent done it for car audio yet, but with my HT setup, what i do is pick a decent volume level, play a fequency depending on what you're testing, like maybe 25-30hz to start for the sub, and adjust the vol somehow while just watching the excusion, to make sure you're not going to blow it.... and keep the vol at a safe level, whatever you think might not blow the sub... now it really depends why you're playing test tones... if you're just testing the subs power, then just watch it, thats all, but if you're doing some measuring, the vol dosent have to be cranked loud as the sub/amps will go, since you're just measuring the frequency responses loudness... so you basically find a safe volume level and leave it there, dont touch it, and test the tones from 20hz and up to whatever, and meter each one with whatever you got, eg, radio shack SPL meter... (wich isnt 100% accurate, but there's correction values floating around) and write these numbers down... get some test tones that test every frequency in you're range and not skip any, like 20hz, 21,22,23,24,25, etc... this can take a while though sometimes...hehe.

Once you write em down, make a graph with em and you can see the response curve for the sub/car acoustics/Box....

If you're sub in its best box, and the car is dampend its best, and the response has lots of dips or spikes at certian freqs, you could always get a Parametric EQ to flatten out the response so all the frequencies play at the same level for great SQ....

so all the frequencies play at the same level for great SQ....

Not for the human ear, remember we cant hear ultra low and ultra high frequencys that well so they need to be boosted for them to sound flat to us.

A quick "burp" every now and then should be OK.

True, True...I'm just getting ready for when i order my AudioQue HD12 in a month or two lol...I need to get it metered but I refuse to pay 30 bucks to the local shop to do it

Funny story-

I once entered into an spl comp with a pair of ported Pioneer 12" 2000 SPL's and a 1200watt RMS Concept amp, I managed 141DB and was pretty happy until a guy in a Honda CRX pulled up and burped 150DB with a single ported 15" DD sub.

Yeah it does - I'm hoping to get around 140 with my AQ HD12 tuned to 40hz with 1100w rms running to her...like I said, I'm hoping...

when you turn it up and it doesnt get any louder, youve turned it up too much

I know that when playing one frequency the sub/amp will play louder than when playing a full range of frequencies, like a normal song. Does anybody have a link to a tutorial or something on the full procedure?
