Hi guys.

I have a sine wave generator, a pink noise generator, a SPM and a 10-band graphic equalizer. Is it possible to do a basic tune-up with these to flatten speaker output?



Thanks in advance.

No. You have no reliable way to check the response at a certain frequency.

The sine wave generator may look like it could provide a way to to check the response at a certain frequency, and it will as long as your measurements are of simple electronics, like power amplifiers.

Pure sine waves are not reliable means for measuring acoustical frequency response because the response measurments they provide can change significantly for nearby frequencies.

Your best choice for the next piece of test equipment would be a RTA, or something like it.

I'll look into RTAs. A ton of thanks :)

Here's everything you'll need to get started with REW. Keep in mind, this is not a plug and play program and it will take some effort and time to learn how to use it. If you want plug-n-play, buy the "XTZ Room Analyzer". http://www.xtz.se/uk/products/mearurement-system/room-analyzer

1. Download Room EQ Wizard for free.

2. Buy this calibrated microphone:

3. Buy this microphone preamp:

4. Get a mic stand, with a telescoping arm, like this:

5. Buy a 30 - 50 foot XLR mic cable:

6. Get an RCA to 1/4 inch phono cable (this one is used to send the test signal to your sound system):

Total investment: around $250 for very competent sound analysis tool. The Room EQ Wizard software is phenomenal, and there is a large support group on http://www.hometheatershack.com/
