In Reply to: RE: Why Kill Valuable Musical Information/ Dynamics of Sound-Waves at the First-Reflection Point? posted by beautox on June 22, 2015 at 14:24:38
Beautox,
You are absolutely right and I was clearly misled by the remarkable increase in improvement already achieved. Have turned a pair of panels upside down and placed each right next to either side of one speaker on its maple block and that doubled the amplification of its music again. Difficult to tell how that will translate in terms of total sound quality improvement until listening after having doing the job permanently to both speakers. Will report back then. Many thanks for your thoughtful input!

That would tend to make speakers sound impressive, and I suspect that is what is going on.

Reuben,
Obviously the Vienna Acoustic Mozart Grands in question are 'coil' rather than 'horn' speakers with which you entitled your response. The principle adjective that I would use to describe music with complete musical information and dynamics is 'engaging' of which we never tire rather than 'impressive' which quickly loses its allure to stylized tedium and ultimately fatigue. It's the three dimensionality, energy and small sound details that take us to the recording event in my view and using (rather than discarding) the extra musical information + dynamics from off-axis sound-waves provides a critical edge in capturing this realism. The logic of fast-reflection over absorption is compelling and hearing the revealing sound improvement settles the matter...

Maybe you just like your midrange comb-filtered?
Beautox,
Regrettably the music with panels in immediate proximity to the speakers does not sound as natural to my ears as when they are mounted on rounds at treble the reflecting distance. Despite the expense of now putting them back the way they were, am grateful to have tested this variant.
Certainly do have a preference for the quality improvements from using all the musical information and dynamics available from the speakers at what sounds to me to be such a marginal loss of tone from frequency cancellation that I cannot audibly detect it when making a direct comparison. However do accept it must be present on some level for the technical reasons that you have provided. We are fortunate to have the benefit of your technical expertise.

Beautox,
At a reflection distance of 4" I suspect the sacrifice in tone will shrink close to inaudible as the improvements in sound quality attributable to including ~40% more musical information and dynamics expand even further. Perfect tone with much diminished content will be perfect for television/ poor recordings while enhanced content and stronger dynamics will be best to reveal good recordings at very little tonal cost. Will see. Am grateful to you for your advice.
