The Advantages of Floor Coupled Up-Firing Speakers

it hasn´t, take a closer look at the pictures - the tweeter is effectively integrated into the floor

Looks like the one I thought to be a tweeter is a port

Anyway, I'm not convinced ! I think there is too much of direct sound from the tweeter. If I place a dome tweeter on the floor and aim it to the listening position I locate the sound coming from the floor. I cannot see how Snell type 1 would be any better.

I agree. The sound would come from the floor just like the sound of a "flodder" will come from the floor if there's no other source (real or reflection) that is strong enough to override precedence. But hasn't all of this already been presented and discussed months (years?) ago?

it is different - take a closer look at the photos

You cannot see?

Why don't You ask diyaudio users who owned it? Read this: Snell Type 1's

Did You actually try it?

What should I see ? Give me some bias and tell what to see, then maybe I see it too

From the Snell thread the owner says:

It does seem that everything is focused down a bit

Yes I've tried. I got plenty of dome tweeters laying around from past failed projects

There is a big difference if the floor placed dome is facing towards the listening position or the ceiling. But only blocking the direct sound by a absorbing pillow makes the dome not to be perceivable as a source.


I think the Snell could work IF the baffle would be tilted much more backwards, horisontally.

Bias? Plain stupid ignorance, that's what is needed...

[markus76]

By the way, here's what James Croft has to say about the Snell Type One: http://www.faktiskt.se/modules.php?n...110107#1110107

the one problem with my original approach, and the production Type One, was that the image is too low... similar to sitting up in the balcony and looking down at the orchestra.

hmmm ...

I haven't heard the Snell. From my own flooder tweeters (tweeters on floor and up-firing), I get very good imaging of normal height.

Maybe the central channel helps pulling it up, but I don't sense the changes in height from left-center-right panning as well.

Maybe I could try turning off the central channel to see if there'd be any problem in height.

still what it has to do with precedence effect?

what the precedence effect has to do with sound source localisation mechanisms in the vertical plane?

Markus first talked about summing localisation in the vertical plane, then about breaking of the precedence effect in the vertical plane, now he talks about plain stupidity, well, I certainly can see some consistence in his posts here

look at the picture below and then try to draw lines for specular reflections from the tweeter towards the listener

but the one who complained about it also says:

I didn't use a reflector so perhaps that's why things seemed a bit low - as though I was looking down on the music.

and the other one - quoted by You commented:

I do get a very convincing image. It does seem that everything is focused down a bit, but I can locate things above and around the speakers.

so the sound was certainly NOT as coming from the floor

but in case of a mono flooder the direct sound was not absorbed, am I right?
