I don't disagree with you on this one. A horn 'can' indeed disappear. I was specifically referring to a small directivity horn.I disagree. Good horn system can "disappear" like any omnidirectional. Problem with horn system is that
Firstly, most of them have horn only in upper midrange and treble section. Below that frequency it is a normal box speaker, so if diffraction can not be controlled well then the "disappear" quality is lost.
Secondly, if the horn is big enough to cover midrange frequency as well (from 800-1kHz up) then the c-t-c between horn and woofer is big and will need a long minimum distance so that the sound of horn and woofer can blend together, unless it is a big MEH (multi entry horn). If listener is at too close position, the "disappear" quality can not exist.
There are a few factors:
1. Observable the way Amir tests speakers, i.e. listening to a single speaker, there should be no pseudo-stereo "spread" in the sound of one speaker playing alone. The sound should seem to originate from a point in space. (It's easy to detect things like acoustically out-of-phase drivers and undue diffraction effects this way.)
…
yes, but that is not about the flaw of the small directivity horn concept, rather than the incompetence or cost saving of the speaker manufacturer. If cabinet is well optimized (with big roundover or beveled baffle) then the speaker can disappear like other type of speaker.I don't disagree with you on this one. A horn 'can' indeed disappear. I was specifically referring to a small directivity horn.
Cheers!
Sufficiently large round-overs and bevels are also effective ways to avoid detrimental reflections at the cabinet's edges. Imo "sufficiently large" in this context would be at least a 2-inch radius round-over, so in many cases a bevel is more practical. In the absence of adequate cabinet edge geometry, narrow speakers seem to me to be more likely to "disappear" than wide ones.
How does ^that^ sound?
Yes. Wide controlled directivity is the answer. If the direct sound of speakers and early/late reflections have similar or same tonal profile, speakers disappear. On top of this, as long as speakers have controlled directivity(which makes direct and reflected sound similar to each other) more reflections make speakers disappear even better. Because if these different sound components are not similar, our brain works hard to integrate both, and that is what makes speakers not disappear.What makes speakers "disappear"?
And can it be measured ?
It feels like you're alluding it's "snakeoil"?What makes speakers "disappear"?

Interestingly Pearljam5000 created the "new" thread exactly 3 years and 1 day after he had created the original one, let's see what happens in 3 years from now.New posts merged in from second nearly identical thread. Lets not create admin work please folks.
Isn't this your first post?What makes speakers "disappear"?

Hello Duke
Have you tried these MDF corners? They come in several sizes and are very easy to use. Once the glue dries you end up with really solid corners! You can paint or vernier.

Thank you for the explanation!New posts merged in from second nearly identical thread. Lets not create admin work please folks.
Lol
I forgot I started this thread and started another one a few years later
And it got merged or something
ThanksI enjoy your threads and learn from the dialogue and discussion that results. I hope your interest and enthusiasm is one day matched by your speaker-buying budget!
