New volume, different low freq cutoff?
#4
Hi, I'm glad my thread created some interest.

As Chillin mentioned, obviously Phantom and all the “new generation” speakers (you know what I mean) must use loudness curves to maximise and optimises output and frequencies
responses.

Phantom does it very well. Other brands lacks in precision and the woofers used are not comparable with phantom.

Of course, a phantom - if uses the same bass curve used @ 82db when reaching 105db …. it would in the best case scenario make horrible noises or …explode or should be built differently (note1).

Same applies to mid and tweeter but i cannot truly recognise these changes by ear.

Now. I can tell you for sure that the news loudness curve or whatever it is fancy to call it now, it is smoother and not so hash when shifting from the old low volume <50 to the high volume >50.

Steamy suggested the curve has been reversed. I would say has been made more smooth and correlated to the new scale and (maybe) lowered to the low volumes. However, being the scale now smoother, a simple relation with the bass eq would explain the changes. Or wouldn’t?

….De gustibus….

I like bass. Meanwhile i was happy with the extra kick of the previous release and i would be disappointed if decreased (btw haven't properly listened at low volume with the new software so no comment from me) i much more like the new behaviour of bass frequencies when increasing the volume (yes an increase, not a switch between power bass to power volume)

Also this is a fresh call to audiophile in search of purity. It does not exist. Only personal emotions and feelings exist. We all get sounds differently.

This is why devialet at this point should be so kind to make us choose a +/- 2db rather than a Nigh mode!



(Note 1)…. About the frequency response in the white paper … clarification.

Having said that i did hardly criticised their marketing material advertising 16hz without saying when they achieved that (50db, 100db 105db??). i did email customer service but they didn't or (didn’t want to) understand the question.

They let you understand that 16hz +/- 2db might have been achieved at 105db for a silver. Every person with common sense though would have taken it as a joke anyway.

Hence i commented  about the changes in their technical specification which i am sure came from the legal dept rather than the product dev team (pardon moi)
