Boring Neutral Speakers

Cool thanks EA

 

SS YOU HAVE A gRYPHON 2100 CALLISTO YES?, ITS A nad s300 underneath
Eric totally spot on sir

 

Took me a while to twig W.M but finaly I get it! LOL thanks a lot
Yeah I kinda worked that one out!

I assume like yourself WM. I run a handful of systems and have too many bits of kit hanging around (well acording to my wife anyway)

 

I think another thing has to do with the design of the cross-overs as for many years both British and American loudspeaker designers have often been distinguished by the 'typical' order of cross-over network they use.

I for one like to see designers try different orders rather than just stick with the typical type used for many years,...probably why I have not bought a British pair of loudspeakers for many years now.

 

Shane - since you're in the biz you ought to put something to that effect in your sig - a link to your site would do. I know it's in your profile but not everyone looks at that.

There is no such thing as a neutral loudspeaker. There are are however designs that get closer than others.

 

Totaly agree...

 

Does anyone know of a 'hi-fi' loudspeaker that measures as flat as a pair of Mackie HR 824? +/- 1.5dB 39Hz to 22kHz quoted.

For neutral loudspeakers I suspect the hi-fi marketplace is not the best place to be looking.

 

Neutral means neither adding nor subtracting.

Mackie choose to neither publish distortion figures nor to show the break up modes of the metal dome tweeter above 22khz. I suspect Mackie 824's add something that is subtracted from the spec sheet on thier web site.

 

Hi,

Well, the biggest problem I have with "most speakers" is that they are designed and constructed fundamentally contrary to sensible acoustics where the speaker remains reasonably unaffected by the listening room and that they have by far too much distortion and compression to be classed as having any fidelity. But that's just me....

Speaking as a complete and utter ignoramus on such matters ... surely the room interacts with frequencies produced by speakers, not with the speakers per se.

If a speaker produces a frequency and the room is such that it will interact, the room will interact, no matter how good or how poor the speaker design - it will interact. What I'm asking is how can you design a speaker which can remain "reasonably unaffected"? Don't get me wrong, I'm not saying you are wrong ... in fact I agree. Just wondered how it would be possible?

 

The Tannoy Ellipse shows very well on paper. Any idea the frequency response of those MEG 901K speakers Thorsten?

I suspect that both the MAckie and the Tannoy are not quite as accurate as they may appear on paper.

Hi,

This graph will have some smoothing, but is fundamentally honest, MEG cannot afford "to fake it" in their main target market, the public german Radio & TV Network.

PS, full datasheet:

Looksd like it varies by about +/- 1 or 2db then! So yet another speaker that compares to the Mackie in the FR.

 

Hi,

Not quiet.

If a speaker has certain dispersion patterns and LF transducer behaviour it will interact much less with the room compared to a more common design (say the 6" Cone Driver & 1" Dome tweeter).

This is a reasonably complex subject, which i have covered in a somewhat populist style here:

(PS Kuei Yang Wang is a handle of mine....)

 

Thanks for your knowledge 3D

 

The Nestorovic Type 5AS Reference were quoted 1.5 dB from 28Hz to 38KHz I believe (Specs from 1998?). With the newer versions the specs weren't modified. Now they are not made anymore. The listing price of the latest model (Reference epsilon, 2004) was 14000$.

 

I'm not convinced by your argument Thorsten I'm afraid. To control dispertion or to tailor reflections? Which presents the ideal?

After all, in order to accurately reproduce the sound waves from say a concert grand, you really want to mimic it's dispertion characteristics as closely as possible.

All loudspeaker approaches are compromises and with current technology, it is simply a case of choosing which compromises are acceptable to you.

 

No, you do not want to mimic the dispersion of the instrument. The recording will already have already all the ambient sounds and thus spatial information of the recording venue. Adding any more is distortion.

Of course, you may personally prefer to add loads of reflection and reverb , no accounting for taste, shrug....

Ciao T

 

I believe my Audiophysic Avanti IIIs are within that sort of range:



...basically quoted as 28Hz->40KHz+/3dB, but it's more even than that if you discount the 28Hz to 35Hz portion, and the bit above 24KHz. Very neutral, super fast, tight and dynamic sounding speakers, though expensive new (mine were s/h)
