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 :)

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

http://www.amazon.com/HOSA-CPR204-Dual-4-Inch-Plugs/dp/B000068O19/ref=sr_1_6?ie=UTF8&s=musical-instruments&qid=1247372678&sr=1-6

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/
