This chart shows has an 11 - 12 db spike between 3 - 5 Khz.

The previous chart (which we have since removed) showed 11 db suck out between 4 - 5 Khz.

That is the exact opposite; a difference of at least 22 dbs within the same range.

Since you stated that "dip in the 3-4 kHz area is a real bliss to the human ears..." What effect does that upward swing have on the human ears?

Its amazing how you want Carver Amazing 60 inches dipole ribbon have a dip in the same freq area than a few grams paper cone FR in a BR box.
Its amazing how you dont see the various depressions Amazing have.

There is nothing in this discussion that is helpful to someone seeking an answer to how various Omega products compare to each other in sound.

Anyone wanting to find such information can get many indicators simply by searching the Omega forum.
Frequency response graphs are next to useless unless more information about testing environment is
provided as well as the sensitivity of the graph gradiations are listed.
Hibuck..

Couldn't agree more. The best "graph" is your ears used in your listening environment. Using this graph I've determined the Omega speakers in my listening room are excellent.

By extension, just because a speaker measures flat doesn't necessarily mean that it sounds good.  One interesting experiment would be to listen to a system that sound great to you and then measure the frequency response in the room.  You may find you like a little unevenness or emphasis in some frequency ranges.

A good Alnico driver is all about sweet harmonics and even the the FF is better than a Ferrite magnet imo.

Is it  true  that Alnico benefits will fade after awhile as Almico lose strength?

no -- not true in any practical way.  any degradation that may occur will not be evident until long after we're gone.  there is some talk that alnico magnets can be demagnetized if exposed to very strong magnetic fields, but that again is not meaningful in normal household environments.

There is many Alnicos FR drivers from the 1950s that yet surprise current audiophiles for it great sound.

i once read somewhere that the alnico are special because they damagnetize easily, and temporarily, and that a moving voice coil, which has its own magnetic field, temporarily lowers the available magnetic response of alnico magnet which, in turn, results in smoother compression of the driver. however, i am no expert on this, just something i came across.

There is only 2 flavors, Alnico and Ferrite IMO.

IMO a whizzer cone is just a mechanical crossover.

Hi everyone,
I'm new here and (since I recenty purchased a pair of Omega K8) I was wondering how they compare to other Omega Series.
Although I really like them, I lack the knowledge (and the measurements) necessary to assess their performance.

[opnly bafld]

I really like them,

Most important measurement.

My name is Joe and Iam addicted in measurements.

[stylerb]

lol. What’s withdrawal from measurements like? Do you feel the need to reduce your consumption of measurements? Do you consume measurements alone?
