The 8C is one of the most accurate loudspeakers that you can buy at any price (Stereophile measurements, Soundstage measurements). Its directivity control is perhaps the best I have ever seen measured. One cool thing it is doing is using phase cancellation to control directivity down to extremely low frequencies, much more than any other speaker its size. Most speakers use cone size to control directivity at lower frequencies, but that necessarily makes them pretty large. The 8C uses ingenuity, and one thing that will help with is room modes since the bass isn't bouncing off of every surface.

One absurd claim from their literature is that it supposedly makes music sound "as it was intended." The problem with that is that most music was likely mixed on audio systems less accurate than the 8Cs. So it isn't likely sounding like whatever the sound engineers mixing for. In reality, most sound engineers mix for a wide range of systems, and there isn't a single 'intended' sound. That is just another audiophile myth.
James, have you gotten a chance to hear them yet? Just curious. Like you, I was really impressed by the measurements and also curious how a speaker like this would compare to a 'regular' monopole speaker. I only briefly got a chance to listen when these were being setup. I haven't connected them to my setup so haven't listened to anything of my own. Gonna have to go hunt for cables in my attic to make it happen.

I haven't heard them. They do look interesting, and I am looking forward to your review.

Well, these are the first set of speakers I've busted out iZotope's Imager to verify that was I was hearing wasn't wrong... the stage on the two songs listed in the photo below have things in them that stood out enough to make me question if what I was hearing was on the track or if the speaker/room was causing something to be incorrect. Spoiler alert: The speakers/room are not at fault. The tracks are just played back at a higher fidelity in terms of imaging than I am simply used to. And it threw me off enough to look at an actual "stage map" of the tracks through editing software.

For example:
On Chord Overstreet's cover of We've Got Tonight, when the vocalist starts singing his voice starts sharp to the left-of-center. I thought maybe this was a room issue caused from the asymmetrical shape of the room wrt to the speakers' position. But, it's actually on the track that way. I've heard this song quite a few times and haven't caught that before. Doesn't mean it was never there on other setups. Just means that it caught my attention.

Another example is: The sax on the Superette track (from Phil Woods' Here's to My Lady) is about 6 to 7 feet to the right of the speaker and according to the imager. I thought maybe it was some artifact or something... surely these speakers don't throw an image *that* wide. But, turns out, that's correct because the content is about 90° out of phase and should pan hard right. These speakers *do* throw an image that wide. Paint me very impressed.








If you wanna demo the tracks, here they are. Very good songs.

This made me LOL (in a good way)...

I decided to use my MiniDSP UMIK-X tonight to measure the Dutch & Dutch 8c's in-room response at the main listening position in my living room. Now, currently the DD8c isn't positioned in the *best* spot. It was the initial setup to see how it's performing; just part of the iterative process of finding the best location and aiming. From the data, I could bring them out from the walls and it would help to level off the boosted LF Additionally, as you can see in these photos, the MLP is about 1-2 feet off the rear wall which is certainly not "ideal" and may be causing the broad dip in the lower midrange. Though, that's easily fixable with a couple shelf filters. With that said, the "null" might even be caused by the couch itself. I plan to re-measure with me in the seated position, holding the mic, to see if that changes anything. I know for a fact my HT seating causes issues around 400Hz that are simply not there when I am in the seat.

But, again, this is just the "ad-hoc" response and isn't intended to represent what I will arrive at in the final configuration. The point of me sharing this is to show the DD8c's the measured response at the MLP is about ±1dB above the transition frequency in my room (~400Hz). The low frequency extends to about +10dB at 20Hz (good thing; you can always shelve the response). This, out of a set of "bookshelf" speakers. Crazy.

I can only imagine how good these are going to sound once I position them more optimally and use the built-in DSP to correct the response below the Schroeder frequency
.
MiniDSP UMIK-X used to measure the response made my life super easy as well. Loving that thing.

(side note #1: the laser shown on the speaker is via a laser level to make sure the microphone was positioned at the correct axis, between the tweeter and the midwoofer)

(side note #2: the HF boost is interesting... will have to investigate, but not something I'm worried about as there is no audible 'hiss' from these speakers that this might otherwise indicate. If I had to guess right now, I'd lean toward the calibration of the UMIK-X as the microphone is super small and that is around the point where I would expect it to break-up, if it's like a standard electet in that sense)

(side note #3: my dog does a good job at absorbing 2kHz
)

The D&D 8c is $100.38 a pound and you have to buy a minimum of 116 pounds for stereo. :)

A bookshelf speaker that weighs 58 pounds might need significant stands and maybe anchors? You would not want something like that to fall over on a child. I imagine moving them around is a bit of a workout?
