Your stands are fairly tall…looks like it’d put you well under the tweeters. Don’t know if that would cause your issue though. I have mine on stands that put the tweeters at ear height when seated.
Am not sure though if it would change anything at obvious differences like loudspeakers where he is used to the sonic signatures of both and would probably easily recognise both in a blind test too. What would be more interesting to me would be if other listeners would perceive the differences similarly and have also the same preference and to which measured parameters those correspond.One way to account for bias is a double blind test.
I bought the B2031A in 2006(?).I don't know why, but I had this problem on all the waveguided speakers I've tried, it's just not there? No matter the placement or EQ it just doesn't happen. Anyone else notice this on waveguided stuff?
this kind of specifications cannot be trueThey are speced by Behringer to play 116dB at 1 meter without distortion.
hi thank you very much Sorry but what is a "compression sweep" ? never heard of thatI have done compression sweeps on the b2031a and it isn’t going to do uniform compression sweeps up to 116dB at 1 meter for sure. But it is a very nice sounding speaker that I quite enjoyed!

Compressions sweep testing is just a way to determine if your speakers exhibit distortion, compression, or inaccuracies as shown by frequency response up to reference level at the Main Listening Position. It’s going to be unique per room, mostly based on distance,(but other factors can sure apply - amplifier power, boundary gain, on/off axis ). Ideally any speaker can play to reference 105dB peaks in your room at the main listening position, that is, if you care about THX reference to have a like experience to the best quality commercial cinema. This test helps ensure your speakers to not change in sound as they approach and meet that 105dB at your seats for dynamic peak cinema content. Worse case it can help you establish a “max” volume with your speakers to know what they are capable of without any negative behavior.hi thank you very much Sorry but what is a "compression sweep" ? never heard of that
By the way if your Mackie have this woofer here wow ... this surely looks very serious
size aside i have no doubt that the Mackies punch a lot more without compression
Thanks a lot But excuse me Why not doing a proper distortion measurement ? is that difficult to carry out ?Compressions sweep testing is just a way to determine if your speakers exhibit distortion, compression, or inaccuracies as shown by frequency response up to reference level at the Main Listening Position.

To test turn off all EQ, put your AVR in its direct sound mode, apply the chosen crossover but turn off subwoofers (as you are just testing the speaker). Ensure your mic is calibrated for SPL, and run sweeps increasing in volume in 3dB or even 5dB steps until either the speaker frequency response sweep stops raising in parallel from the previous sweep for the amount of additional volume applied, (IE a 5dB increase on the volume dial should increase the frequency response sweep by 5dB across the whole - if it doesn’t — you have encountered compression. The limitation of the speaker, amplifier, or placement relative to your MLP. Raise until your hit reference, the frequency response plot shows a non parallel raise, or until the speaker sounds audibly distressed. Quit immediately after either negative condition is found.

I don’t have the Mackie c200 anymore. But their components are discussed in detail here. They are a very competent EAW designed speaker for the money. (Although they went from $200 to $300+ in the last 5 years)
Not any more difficult, but two things - how do you remove the room distortions unless you perform this test outside? Also if just one plot is showing as in that test at 110dB. It doesn’t tell you anything about whether the speaker can perform at reference at your seats. I see this as two different tests with two different purposes.Thanks a lot But excuse me Why not doing a proper distortion measurement ? is that difficult to carry out ?
it must be very demanding because there is no trace of that in almost any datasheet
I like this kind of reports

i have no way to check instrumentally and i am really sorry for thisAssumptions assumptions.
what if the guy is easily impressionable ?
Possible. He wouldn’t be the only one though.what if the guy is easily impressionable ?
hi thank you very much for the link ... i think i have found what i was looking forPossible. He wouldn’t be the only one though.
Linkwitz Orions beaten by Behringer.... what!!?
Having lived and refining my DIY dipoles I'm very happy how they render recording. Obviously the Orions are my dream speakers which I would never afford with such mortgage :vampire:. The dipoles are very untiring and natural to hear albeit their obvious limitations in Bass and transition to dome...www.diyaudio.com
