I was reading a couple of articles in Stereophile by John Atkinson about 'Measurements of Loudspeakers' and was diving deep in this section about 'Step Response'. In this article a near perfect step response is shown as below,
Only a handful of loudspeakers measured by him (around 10 out of 350) is having a near perfect step response. (Only 3% of the speakers fall in this category) Quad, Thiel, Dunlavy, Spica, and Vandersteen.... to name a few. I am not seen any reputed Indian speaker manufacture publish this data (Rethem or Cadence) or reviewed by someone else - atleast not known to me
This is a typical loudspeaker step response (97% of the speakers fall in this category) as below,
I re-reviewed my own designs for the 'Step Response' and found them to fall in the not so 'Perfect' step response (97% category). Below are the step responses of my own designs build using 'Dayton Reference Woofer and Tweeter'. Though they sound very good but does not have the near perfect step response.

Dayton Floor Stander:
This made me to tweak my own floorstander which has a Peerless India 5.25" Kevlar (Originally made for JPW) and Vifa-Tymphanay Tweeter -BG/OG series. I have redone the entire crossover to try and achieve maximum Phase coherence as possible and the results are amazing to speak.
Peerless + Vifa (After Modifications to crossover):
This speaker now sound very nice with no clutter in the mids, smooth rounded highs with excellent detail and very real, articulate and pleasing sound with no over or under emphasis of any frequencies. This speakers now do full justice to the music by adding nothing or taking away anything from the music. Music as it should be.
So are Peerless India / Vifa drivers good.
Yes and No.
Yes if you design properly with them giving all attention to measurements and details.
No if you give a damn about phase, FR, impedance and measurements in general.
So are Dayton drivers good. Yes. They are very forgiving and do not sound very bad even if you give a damn about measurements and design with your ears subjectively only.
