Hi ROJ,got a PC with a ReWriter?Its easy to set up Test Tones using Freeware.Try a google search for audio measurement.You can Download Scopes Spectrum Analysers Tone generators and Frequency calaculators.I got a nice one from Germany.Great array of tools and it fits on a Floppy.You have to bear in mind that these tools are only as good as your soundcard/microphone.You can generate Pink noise White noise Sine or Square waves.With an audio editer ie Sonic Foundry's Sound Forge is great for assembling a Test Disk.I'm using SoundForge now to help with my car Subwoofer.I burnt some Tones on to a Disk and played it with a Discman plugged into my Subwoofer's filter circuitry and took the output straight to my PC.Just Recording the output and Zooming in on the .Wav file shows a clean representation of the test signal,I have no DC offset(I built the Filter my-self)The FFT or Spectrum Analyser shows what the filter filters out when I play music,and if I had a good Microphone I'd measure it acousticaly too.Are you saying you can't move your speakers and ones louder or too much boom from another and that you need to eqaulise the level?Maybe plug the PC in to your HiFi and you could modify with an audio editer.You could use the 1/3 octave equaliser(graphic equalisers with lots of sliders)for precision.Don't push the sliders right up for max bass yuk,got no bass,try bringing the mid down abit.Allways better to reduce than boost.If you find your'e-self adding more than at least 5dB to a Frequency,then you have a problem so go easy +/-3dB is a good area to work with .You can make the eq on the left different than the right,same for volume/balance normaly this can be done in Real time.Hope this helps.Happy Listening.Mikee55
