Where is 200 HZ?

[talltigeguy]

I posted this thread last night, but must have forgot to hit the submit button. If someone finds it, let me know where I put it.

My NVS Tyrants say to put the crossover to 200 Hz. My Precision Power PCX 4125 has a crossover that is labeled 20 at the bottom and 20K at the top. So am I right to assume that it is a logarithmic scale? That would mean that 200 Hz is about a third of the way up, 2000 Hz is about 2/3 of the way up and 20K is all the way. Am I right?

I was just out there goofing around with the amp. The upper end is actually labeled as '4K' and the lower end is labeled '30'.

I was in the right ballpark.

You probably already figured it out, but 200Hz is a really high bass note. Many woofer test will ocsillate from 20Hz to 200Hz. Human ear is about 40Hz to 20hZ depending on hearing loss.

So how do I know if the crossover is at 200 Hz? That is the question.

[spharis]

You have to guess.

Actually a better way is to take a 200Hz tone and play it. Then tune the EQ until it cuts off. Give me a few and I will link you one up.

Thanks! I will get that to my ipod and play around with that. I think that is going to be very useful. I really appreciate it!

I set all my xovers with test tones also. Play the tone on a loop and adjust till the speaker cuts out.

I got to play around with my test tone today. It worked like a charm. The only problem is that I need a second person to tell me for sure when it cuts out because when I have my upper body buried in the amp compartment, I think that I know when it cuts out, but am not sure when it is about perfect. The crossover is turned with a tiny flat blade screwdriver and it is not quite simple to do.

Lovin' Powell is coming over tonight to do my taxes, looks like I will enlist him for something funner too.

LP helped with the crossover settings. I just left the crossover where I can just barely hear the 200 HZ tone come in at full strength. The speakers sound very good that way.

I'm glad you found your 200 Hz

Let me know if you need more tones. I have a bunch at www.wakeboatworld.com in the set your gain tutorial.

Thanks for the link, now I have a stupid question How do I download the tones and save them?

[dogbert]

You import them into your iTunes library. I classified them separately so I could find them.
