there are some true hifi products in the market that overcame in quality price all the others by far. And for this time this is true also if incredible .

Audes 146 a true optimized with specialized midrange loudspeaker,this fact rare at this level price. And also rare is the quality of the used woofer,at the best level pc the market without cost limit.
The costa is in Italy street price only 1600 eu for pair .
Into the photo you see it on the first on left.

 

 

la risposta in frequenza
Da Wikipedia, l'enciclopedia libera.
La risposta in frequenza è un potente strumento per
caratterizzare il comportamento di un sistema
(meccanico, elettrico, ottico, ecc.) lineare, sottoposto a
sollecitazioni variabili nel tempo.
Il concetto base consiste nello stabilire quale è la
relazione fra ingresso e uscita del sistema, quando la
sollecitazione applicata e la risposta (uscita) sono
variabili nel tempo. Dato che qualsiasi segnale
d'ingresso periodico può essere scomposto in una serie
di sinusoidi di frequenze diverse, se si conosce l'insieme
delle risposte alle varie frequenze in ampiezza e fase, è
possibile ricostruire il segnale d'uscita senza dover
effettuare calcoli specifici per ognuno degli infiniti tipi
di forme d'onda di ingresso.
------------------
Aggiungo semplificando..
In altre parole..il segnale musicale e' variabile in
maniera infinita,ma come si fa con la conversione
digitale é ricostruibile associando molte e varie
sinusoidi di diversa ampiezza e frequenza . Quindi
questa caratteristica fondamentale nelle varie
frequenze udibili,da 20 a 20 000 hz.,deve essere
assolutamente trattata con omogeneita'

example:

 

by soundstage:
On-axis frequency response - Measured directly in front of the speaker face (2 or 3 meters).
Purpose: Shows the forward-firing output of the loudspeaker across the audible frequency spectrum.
What it tells you: In comparison to the 15 degree and 30 degree measurements we do, this measurement should be the flattest (la linearita' su cui insisto) and have the widest bandwidth. Bandwidth refers to the upper (highs) and lower (bass) frequencies that the loudspeaker under test will reproduce. Most good speakers today will extend easily to 20kHz and beyond, although bass performance will vary widely. Full-range is considered 20Hz to 20kHz, but only the largest loudspeakers can approach 20Hz and even some very large speakers will not be "flat" at 20Hz. Many subwoofers cannot reproduce 20Hz at the same sound pressure level as they reproduce 50Hz. One should recognize that since these measurements are performed in anechoic chamber, they will generally show less bass than what you can expect in a real room (vedi studi di Allison:incrementi in casa nei bassi daa 6 a 9 db).

Although all frequency response measurements will have some bumps, in general, good speakers will have a smooth and even response within its bandwidth without many severe dips or bumps. Dips indicated less output at that frequency while bumps indicate more. The audible result of the dips and bumps in the response curve will depend on the frequencies where they occur. A bump in the upper bass may make the speaker sound boomy. A dip in the midrange can make the speaker sound recessed
A bump in the upper bass may make the speaker sound boomy: qui si riferisce alle esaltazioni ai 100hz.
Purtroppo poi nelle prove non si mette poi in evidenza a sufficenza quanto questo sia grave ma si sorvola..

Under a wrong image,not enough linear:

terrible by 30 to 500 hz…but this is today a standard NO true HIFI
