Moving away from box speakers: Diesis Audio vs Avantgarde Acoustic?

IME horns, while more directional than cones aren't any more directional than panels. In fact, horn drivers need more distance to integrate well at the listening spot, and your room is of modest proportions (like most of us). As such, (not to mention I haven't heard a single pair of horns that integrated well and never sound natural to me) I'd recommend the Clarisys Minuet. I know folks who've heard them and rave about the natural tonality and uncommonly incredible dynamics. Good luck in your pursuit and enjoy!

As much as I love Dipoles (also in small rooms) they absolutely need a uniform symmetrical wall behind them and optimally also symmetrical side walls.

This is not given here and therefore I would recommend Horn Speakers.
 
I dont agree at all .
You can may be get good coherence at 1 m
from small 2 way system

Im talking big 4 way systems , like my XPE .

Thats a shortfall of the Wilson XVX system, to High / multiple stacked units resulting in not a coherent sound output .(to my ears at least).

One of the best , if not the best coherent LS is the Rockport Lyra

Then all are not coherent designs your 1M testing will show this ..!
 
And i am talking about real four column speaker systems not puny little speakers ! ;)

4 tower system or multi tower systems can do so too if the mains are time coherent and balanced .

You have to balance how the bass towers integrate on the ML thats not so good when done right you cant even hear the bass towers it all should appear to come from the mains ..!
 
Measuring sensitivity with one watt at 1 m its a standard Spl measurement. at 1 meter mic distance

When i design loudspeakers i do may be 50 measurements ranging from 1 m to 4 meters .
At different angles as welll to get the full picture.
And make X over changes accordingly
At 8ohm 2.83v and 4 ohm 2.00v= 1watt
there is usually a little cheating in favor of the manufacturer
 
Stacked or linesource? the point is you can make a FR speaker fully coherent at 1M ..!

Its been done for decades ...!
 
The more units a speaker has in general the more stacking occurs , thus the more distance is required to make them sound as a whole.
The drivers need a certain distance to blend

You must be running steep slopes or ceramic drivers or both, their out of bandwidth performances are not really up to par so i can see coherency problems ..!

Do you measure anechoic ..?
 
Speakers with limited bass output do not count ! ;)
They were 2.4 meters tall and 55 cm wide and were flat to 20hz with tremendous bass…even better than my Infinity IRS betas with 4 12 inchers per side.

I could imagine that the horn driver and bass driver opus 1 are selected again (matched), so cessaro actually uses tad&supravox drivers. But there are also now in-house developments. I can't say anything more specific.

Now in the german audio market
I can really second this recommendation.
I repeatedly preferred the Opus 1 over the bigger models at shows.

Not cheating its 2.83V test voltage , not referenced to 1watt . If using 1w/M then you have to specify such ..!
If you want to specify the sound pressure level of a loudspeaker, you have to specify the impedance and the voltage used. For example, if you have a 4 ohm loudspeaker and the standard output is 2.83 volts, that is 2 watts of power and not 1 watt as with 8 ohms. So the loudspeaker has 2-3db more than it actually has.

Yes and no , the standard test is 2.83V you dont have to specify , you only specify impedance if you are referencing 1watt ..

2.83v@1M ... 93db (4ohm)
2.83v@1M ........ 93db (8 ohm)

Both are sensitivity references ..!

both speakers will make 93db when 2.83V is applied at speaker terminals granted at different power levels.

Same sensitivity but different efficiency levels , which is what you are eluding to..

Can't be done at 1 m, you need a big room, with distance to your listening position. Deep bass does not even develop at 1 m, i have set these systems up 25 years, in real life, not just theorizing in audio forums. :rolleyes:
