Is that figure for tones? Source?
Just FYI: https://secure.aes.org/forum/pubs/journal/?elib=5147
This pure sine table everyone uses (source unknown). Since electronic music exists, it doesn't seem far fetched to use it as worst-but-still-realistic case.
Nice to see your not-Klippel-money rig kinf of validated (again).For what it's worth -- and just to really drill down the idea that speakers should, in fact, measure very similarly across different measurement rigs -- here's how my spin of the 8C overlaps with Erin's:

Of course, I couldn't measure directivity reliably below 200Hz, and I have far less resolution in the low mids, but we see excellent agreement. So don't let anyone tell you you shouldn't expect consistency! (Remembering a certain youtube video...)

I do not. I frankly don't put much stock in it. But I have provided the data in my OP so hopefully the guys who normally do all the "extra" stuff will be able to provide that. I tried to match Amir's outputs so they could just drop my data in their scripts and go.
Yes! Unlike some other interesting designs where the speakers "disappear" in the room only after following the direction to pull them 4 feet off all walls into the roomBut your measurements here seem to suggest that, finally, we have a loudspeaker which can be placed close against a wall with the attendant LF gain without introducing a whole range of problems further up the frequency spectrum. They're not cheap but would certainly be on my shortlist if I were in the market for such a thing . Being small, unobtrusive &, placed against the wall, they're conducive to domestic harmony, too
How do you think they differ from your setup of rme, nc502 and choice of speakers.Jeez I need more coffee.
Great write up.
Good question which I have no answer for, other than speculation. But you can get an RME ADI-2 DAC fs + Hypex NCore NC502MP based amp for around 2k usd and that leaves some 8k usd for speakers, which is a lot of speakers to buy, until it reaches the price of the D&D 8c.How do you think they differ from your setup of rme, nc502 and choice of speakers.
because you can apply eq after calibrating a mic with software. Do you think the combined sinad with eq option would be preferable to this speaker.
perhaps on value alone.

As such, the “score w/ sub” is not accurate, but I added it for consistency.
This is for sure an…intimidating speaker.
Erin, you didn’t hop on the ol‘ photo copier did you?

I did! Front side first. Unfortunately, that image is to scale.
