The measurements that you showed here are NOT in line with what we have for on-axis frequency response, spatial average, or sound power for the IN-8. We would not put a loudspeaker that measured like this on the market. We would like to understand what's going on with the speaker you have.Your measurements and comments don't line up with what we've experienced with the IN-8, or the reactions we've gotten from others. If the speaker is defective, it is covered under our warranty, and all of our retailers are quite good about replacing product when there's an issue like this. In this case specifically, we would be interested in getting the speaker back to analyze it ourselves. We are more than happy to provide another IN-8, as well as an LP-6 and LP-8 if you'd like to test those as well.If you reached out to us about this via our online form, email, or social media channels, please accept my apologies for not replying yet. I just spot checked our inboxes and didn't see anything from you. These speakers have previously been reviewed on this forum, and the experience seems to have been entirely more positive. Full disclosure: we have not had any contact with the person who wrote that review.As many commenters have pointed out, we do not have FR or CLF data published for the IN-8 yet. Our intention is to have all of our loudspeaker products tested by Pro Sound Testing in Indiana. To be frank, the IN-8 has sold about twice as well as we expected so far, and so we haven't been able to spare a pair to send to them for testing. Perhaps this was hubris on our part, and we apologize for the lack of transparency. It is not our intention to hide the performance of our loudspeakers. Quite the opposite: we prefer to provide 3rd party data for the sake of trustworthiness. To be clear, we will be having this testing done and will publish it on our website as soon as it is complete.Here is a link to another analysis of the IN-8 where the reviewer did his own measurements: http://www.hifi-forum.de/index.php?action=browseT&forum_id=30&thread=13717&postID=33159#33159 His comments are in German, but you can see the overall frequency response of the speakers. Minus the bumps below 200 HZ, which I write off to the room, these measurements reflect what we would expect as far as the performance of the loudspeaker.Here you can see one of our own comparisons between the IN-8 (Green) and the LP-8 (Red.) This is an apples-to-apples comparison of these loudspeakers measured in the same place in the same chamber. The reason we're sharing this is that there is a wealth of 3rd party data on the frequency response of the LP-Series (including what's published on our website, linked below,) so you can see the response of the IN-8 in that context. I've also included Stuart Yaniger's review and measurements of the LP-6 below so you can cross-check vs. what we've published.In the measurements here, you can see some differences between the IN-8 and LP-8. The LP-8 is a bit messier at about 800 Hz. This is a box mode that comes out through the port tube. Because the mid-range handles these frequencies on the IN-8 it doesn't excite the box mode, so you don't see it on the IN-8's response. At 10k, the on axis response shows a diffraction from the baffle edge of the midrange for the IN-8. Looking at the spatial average response (ours is below, but this shows in your measurements as well) you can see that this artifact averages out when off-axis information is introduced.You can see in these two measurements that the IN-8 and LP-8 are nearly identical below 300 Hz (330 is the xover of the IN-8 woofer) and very close up to 800 Hz. At 800, you see the same port resonance that I mentioned previously. Above that, the two speakers stay very close. Above 4K, octave-to-octave balance is maintained even though the shape of the baffle causes some artifacts in the response.LP-Series Measurements:LP-6 vs. LP-8 (Scroll DownStuart Yaniger's ( @SIY on this forum) LP-6 Review: https://audioxpress.com/news/focus-on-acoustics-speakers-and-more-in-audioxpress-august-2019
