In the not gated far field measurement, all the data coming from the microphone are used by Speaker Workshop to draw the response, therefore the environment  interacts completely with the speaker. This kind of test is useful to better understand where to place the speakers in their final location, allowing us to try different positions and to compare the responses; however always try your ears as well, cause they will be your final judge! You can use the responses to practice your hearing as well: knowing, by the measurement, that one speakers position is more bass rich than another, try to figure it out by listening; to make it more hard, do the contrary: first listen and note the differences, then measure to prove your conclusion. As a general rule, a speaker close to the back wall causes an increase in the bass region, as well as if it stays close to corner walls. Same thing happens the more the woofer is close to the pavement.

To perform the not gated far field measurement, use both the speakers and place the microphone where you usually listen to music, thus recreate your music room with the difference that the mic will be your ears. To use both the speakers, try the MONO switch of your amplifier, otherwise use an Y cable to connect both the amplifier left and right input to the sound card left line out; do not connect both the speakers on the same channel of the amplifier output, unless you know what you are doing! With everything connected as in the gated measurement, and the volumes set to get a 20-25k (depending on your card clipping level) on both channels of Speaker Workshop VuMeter, Sample Rate and Sample Size to the maximum that works best with your card as you tested in the SWSetup section, choose a REPEAT COUNT of 5 (in OPTIONS/ PREFERENCE/ MEASUREMENTS) or more, depending on your test-room noise and used Sample Size (I use 20 repeat) and check that the USE PREEMPHASIS box is unmarked; then click twice on and then on or click on MEASURE/ FREQUENCY RESPONSE/ FAR FIELD; check SW VuMeter to be sure the values are almost equal for the left and right channel and in the 20-25k range; a new file will be created: "Focal A.Far Field". Open it.

As you can see it is not very readable, therefore we need to smooth it: click on TRANSFORM/ SMOOTH and select 1/3 octave then   to see the result immediately; if you press CANCEL the smoothing will not be applied while clicking on will make it permanent:

Actually a better and faster way to perform this measurement is to use a Real Time Analyzer, like SpectraRTA; I did it and let's compare the results:

As you can see they are almost the same, telling us that there is a big hole in the 30-150 Hz region; the aim is to reach a not too bounced response, with the high frequencies gently rolling down. To give you a better idea of what the speakers positions can cause, I compared two measurements: with the speaker on the floor and with the speaker on a table at 80 cm from the floor. Here it comes:

As I said before, a woofer closer to the floor causes a boost in the lower region, that in our case helped to normalize a bit the response. Well, after this long journey together, it's time to start our own project, mine is the Double Chamber Reflex!
