I know what you mean. You surely have more experience than I do, so I respect your approach, if it works for you. I'm fully prepared for the horror show when I get the speakers in place and do more tests. It will be very revealing to compare the test curves from outdoors to the test curves done...

Thanks, Rob. Two of the curves are acceptable to me. The green one isn't, but I think I can rectify that. I don't think I'm over-thinking anything. Okay, I may have geekish tendencies! My reason for wanting to do these speaker tests was to determine how accurate the speakers are, while still...

I wondered if that might be a possibility, even though the wall was at 45 degrees to the speaker faces, and underneath the speaker. Maybe draping a load of blankets over the wall, under the speaker would be worthwhile. Thanks also for your earlier suggestion re isolation, and trying the...

Wow, this is more like it!! :P After reading your helpful comments, this time I placed each speaker atop my 5ft concrete-block garden wall, facing away from it at a 45-degree angle, and such that the nearest other garden walls were 18 yards away, behind the mic, and at 45-degree angles, to...

Oh I see. Yes, I can do that, for sure. Thanks!

Thanks for the input, Rich. I will think about that article. I should stress that my latest measurements were done outdoors, in the middle of a lawn, to eliminate room resonances though.

You may be right, Bob. I hope so! I only have the one measurement mic, unfortunately, and those things are expensive. To buy an alternative one would likely cost half of what I paid for all three speakers. One thing that could be a culprit, is that I had each speaker sitting on the edge of a...

Today, I tested the three speakers again, and got much more comparable curves from the three Truth speakers (probably because the REW setup was more correct and input monitoring was switched off). All three speakers were measured outdoors, with the measurement mic 26" away from each speaker...

Thank you, Rob. Yes, could well be, as I got vastly more comparable curves from the three speakers, today (see post below).

Thank you, B! :) I actually thought of that, before today's repeated tests (see further below). Big difference! But still troubled by the wildly un-flat resposes recorded.

Thanks for that, BSG. I had the mic plugged into channel 2 of the audio interface and used the same channel for output, going to whichever single speaker was being tested. Perhaps that was a mistake, was it?

Today, I measured the two Behringer Truth B2031A speakers, outdoors, plus a third speaker which is the older variant called B2031. Here are the readings. The mic was in the same position for all three speakers (26" away from speaker, pointing at the spot between the woofer and tweeter)...

"World class studios" just buy the latest ATC monitors or whatever. Paupers like me can't do that!

Thanks for reminding me of that site/post. I haven't seen the circuit boards in the flesh yet, but if they are the same as his, I will probably try those mods. Going by the photos, each resistor seems to have a nice big blob of solder at each end, which is handy, as I'm not the world' most...

Thanks for the suggestions, Rob. Yes, I must get organised for outdoor speaker testing. I have a shedload of speakers that all need testing outdoors. I will devote a day to it, as soon as I can. Yes, I've noticed how the SPL of different frequencies changes according to listening position...

Oh, that's very interesting - thank you so much. I must investigate those possibilities and see what can be done to mitigate them, and see if there's an improvement. Yes, I intend to test the speakers outdoors, when I get the chance. It will be very interesting to compare the two graphs: indoors...

Ah, I see. Here it is to 200ms - thanks:

I see. Now I wish I hadn't ordered it! o_O Still, it was cheap (used), on eBay, so maybe it will come in handy for something. It has a subwoofer out with adjustable crossover, a feedback detection system, and a couple of other handy features so hopefully it'll be worth having around.

Thank you for your input, B. The measurement mic is a Behringer ECM8000. I'm not too familiar with waterfall analysis, so I hope I have set up the following graph suitably for analysis purposes. It shows up to 700Hz (right speaker only). If you want me to change the graph settings, or post the...

That's certainly true in my room. I haven't tried changing the room EQ switches on the amps yet. If that doesn't fix it, my 31-band hardware equalizer probably will, when it arrives. To my ears, the higher frequencies could be more pronouced, but the graph doesn't say the same, so it must be my...
