Why are fullrangers more intelligible ?

[planet10]

The very first Acoustat i think was the Acoustat-X with its direct-drive high voltage amp.

I lived with a set of those (they weren’t very good), i am pretty sure the panels were much the same as my Accoustat 2s.

Very subjective I suppose, but even that's a matter of opinion

It's a shame you didn't experience them for what they are worth.

You sure you lived with a set of them... and not remember how they had to be full range?

They are/were a very different animal than the Acoustats 2s.

 

[Disco-Pete]

The 2s are also full range. To be more specific, The X was forerunner to the Monitor 3 and 4(three and four panel) , also fullrange directly driven but as all second gen iterations whether directly driven or with interface, full range or later Spectra, was raised 12" off the floor as opposed to the X. The X was a bit tubby in the upper bass/lower mid range. But still considered the "King" at the time due to the DD Servo OTLs. The King is alive and well

All stacked paneled versions have their lower panels on the floor.

Yes, didn't mean to confuse otherwise.
My statement about being different to the 2s, was about the excellent sound of the servo amp, and wondering about planet's experiences/comparisons

 

[Disco-Pete]

I am currently running a pair of folded 6s

They probably lacked DDR, whatever that is.

...I would bet a good active crossover implementation would improve intelligibility on many systems...

The part of the crossover that matters the most with that kind of speaker is the acoustic design, and the blending choices. You can use whichever filter methods you are most comfortable with.

 

[cogitech]

...whatever that is.

As if it hasn't been explained to you before.

Downward Dynamic Range - The ability to accurately reproduce low level information in the presence of other stronger signals.

You can argue till you are blue in the face whether or not you can hear it or think it is important, but claiming you don't know what it is ?

 

[scottjoplin]

Can we have a physical explanation of what it is rather than mumbo jumbo? How does a large signal swamp a smaller one?

 

[planet10]

The Xs had a top end that woud tear your face off. Accoustat 2s (driven by NAIM) wer emuch better, but definitely a 2-way.

The Accoustat answer man could probably provide a more nuanced answer.

SJ, I'm not here to defend the concept of DDR nor refute it, as I am neither a proponent of it nor a detractor. Perhaps I am as skeptical as you are about it - but I can't say I don't know what it is (or what it is supposed to be).

 

[scottjoplin]

I don't know what it's supposed to mean, ie "whatever that is". It doesn't make sense to me.

Are you kidding me?

The X's have a HF pot to dial in tonal balance, that can be adjusted down to sounding outright dull.

You really lived with X's for awhile?

 

[planet10]

Yep. The level control was inadequate. The Xs are more memorable for a night with Mary Jane e(not the kind you smoke) — nothing to do with hifi.

[Disco-Pete]

Your description of the Acoustats is opposite well known consensus, You sure you're talking about these speakers?

 

[Joel Wesseling]

Did someone say there is a full range that can do 30Hz to 20kHz?

My current drivers (in their enclosures) can do 50Hz to 30kHz, nearly flat

What drivers are these? I'd like to hear a full range flat to 20k with no cone disturbance in the treble.

 

[Disco-Pete]

They would be the mentioned Acoustat X/Monitor 3/4, Model 3, 2+2.

I did say "nearly". There is no perfect driver.
