    Call me new, but I was wondering what all of you use to take measurements of your speakers and room responses? I read about this stuff all the time in here and I want in. Just finished my first set of speakers and have three more projects on the way, so I wouldn't mind taking measurements on how they perform. Thanks for any replies.

    I use a Behringer ECM8000 measurement mic -> Behringer DSP110 Shark (for phantom power and mic-pre-amp) -> Sound Blaster Digital Music USB audio-in -> 1.8gHz notebook (running on battery) -> ETF5 or spectrum labs or spectraplus (depending on what I want to measure)

    I use pink and white noise for quick one glance maesurements, pure sine tones for harmonic distortion and THD measurements and slow sine sweeps as a more accurate alternative to the noise signals.

    ETF. You can use a SPL meter for the mic, but if you're serious about it, get a calibrated mic/preamp setup.
