Stand-mounted vs. Floorstanding

[A800]

Please can you let us know what do they do right, while you are it, can you please provide us with any measurements outlining their superiority in said areas ?

If they got paper cones for example they sound very natural.
No idea how to measure this.

Well sure, if you believe that room magically stops influencing speaker's response at transition frequency like it hit the invisible wall, well whatever rocks your boat I'm fine with it.

I said no such thing. All I've said is I agree with the research as I have no scientific basis from which to disagree with it. You don't either, but that hasn't stopped you from disagreeing with it.

Of course the room influences a speaker's response all the way up. I agree with the research that says at high frequencies our ears separate direct and early reflections from late arriving reflections--which is why many who do EQ at low frequencies, will not EQ at high frequencies based upon the steady state room curve--possibly messing up the direct sound to "fix" late arriving reflections. So if that's your standard for "using room EQ," then you are correct to be skeptical as most of us don't agree it's generally the right thing to do.

To accurately reproduce that kick drum, you need this subwoofer...

 

[March Audio]

Yes, but unfortunately they have a deficiency of not so linear frequency response over the audible range which is more important than time-alignement.

Not only this but also a bad off axis, response.

True but you can combat this using phase plug like methods.

Fullranges have their drawbacks also but some do so many things right that it doesn't matter (for me at least).
I use a custom enclosure and a phaseplug kind of thing on my triple cones.
Nice natural sound.
After listening to fullranges for a while the sound of multiways seems to be torn/disunited to me.

.... Mmmmmm.... They have too many significant drawbacks.

Have you listened to the Fane Sovereign 12-250TC or the Fane Sovereign 15-300TC?
The 12 inch changed my mind.

I'm afraid you can't. It's a fundamental problem of cone size V signal wavelength.

A 12" driver will beam high frequencies.

I used a V-shaped vertical rod in front of it.
Worked for me.

Yes it will by nature.

[March Audio]

Yes it will by nature.

So it's off axis response is going to be all over the place.

 

[A800]

Did you measure it?

Yes.
Since the highs were still somewhat dominant (on axis, off axis not so much) I used a small square shaped piece of polyester fleece in the middle on axis on that rod to dampen the highs a bit and then it sounded fine.
I didn't bother to measure it afterwards though.

Are you seriously using this and consider it full range? It's 20dB down by 10kHz!

 

[A800]

Are you seriously using this and consider it full range? It's 40dB down by 10kHz!

It is not.
Due to the triple cones it will go up to 18kHz easily.

Try this one:

Yes, but just imagine the bone crushing full range bass you get from 3.5mm Xmax.

 

[March Audio]

It is not.
Due to the triple cones it will go up to 18kHz easily.

The measurements are there in front of you. It does no such thing.

There is a difference between having a response and having a flat response.

ALso the cone will probably be breaking up.

Your "Measurement" says "Simulated Response" on top of the diagram.
Look at my post above which is a real measurement.
