I bought and used the Canon R5 Mk II for taking gymnastics photos of my daughter's high school team this past season. I'm sorry to hear about the Immersion Networks implosion, as I was looking forward to future developments from your research, especially those you couldn't discuss previously. I...

I believe that C50/C80 will be inversely related to T30/60. You might be interested in reading the following: Laukkanen 2014 https://users.aalto.fi/~ktlokki/Publs/mst_laukkanen.pdf “The results of the preference tests clearly showed that mixing engineers prefer quite dry rooms (T60 of 0.15 -...

By "more," I believe that you mean a greater number of. If you have a perfectly symmetric setup with respect to loudspeakers' distance to the ipsilateral boundaries, the second speaker may excite the same axial modes as the first. For example, consider the one versus two speakers at the same...

I tend to consider this as a cognitive illusion, since concertgoers can have different seating location and sonic preferences (see comments by Beranek and Lokki at https://www.audiosciencereview.com/forum/index.php?threads/concert-hall-acoustics-links-and-excerpts.51487/), and virtually none of...

It sounds like you're asking how to measure and compare subjective experiences, like "how can we measure and compare how painful different sorts of trauma like stab wounds or blunt force impacts are?" You can create numerical rating scales, but I don't think that there is really any objective...

I forgot to include the link to the post for the Salon 2 and Array 1400 measurements: https://www.audiosciencereview.com/forum/index.php?threads/jbl-synthesis-1400-array-measurements-interpretation.27853/#post-966141 I see. I took your statement "My hypothesis is that mono listening (both...

Hi, I thought this previous post might be relevant to the first part of your post: https://www.audiosciencereview.com/forum/index.php?threads/alternative-perspective-on-the-harman-loudspeaker-preference-curve.50602/page-5#post-1848097 This blog post is certainly relevant to the second...

If I understand correctly, your hypothesis would predict that the highest rated speakers in Harman's listening tests (mono) should show lower DI at 1-2 kHz ("pumping too much energy...into the room") and higher DI at 2-5+ kHz ("attenuating") because directivity index is sound power minus...

Sorry, I'm not clever at all! However, concepts like critical distance don't apply to small rooms since there is no true diffuse or reverberant field (this is discussed in Sound Reproduction). Can still try to approximate with various measurement parameters. Also, in typical room setups, the...

Oh, besides Sonos, also could consider Kef LS50 Wireless II or one of their other wireless active designs, since they have some built-in boundary compensation adjustment and balance options, also make it easier to add additional speakers for the dining area, etc.

This might help you feel a bit better about the wall behind the listening position...

Here are some thoughts from an amateur who has read a little bit: I'm sure you know that PEQ won't help with the nulls or destructive interference. Where to start is not "a well-behaved speaker." The starting point is one's priorities, which here are significantly constrained by the room and...

Also from second edition of Sound Reproduction by Floyd Toole: I'm assuming that OP does not want to stuff the bookshelf cavity with fiberglass, but if so, it would make things less bad:

Speakers in bookshelves will cause cavity resonances. Here's an example from second edition of Sound Reproductio by Floyd Toole: And in cavity: So lower your expectations accordingly. Cardioid speakers like Mesanovic CDM65 or Dutch & Dutch 8C likely more than you want to spend, also setup...

No, the study population was different in terms of total number (31 vs 10) and likely age range (I'm assuming that the five from tests A and B who went on to participate in tests C and D were not the 6 or 96 year old, for example). The generalizability of tests A and B is much clearer to me than...
