except your statement you stated as "fact" is completely incorrect and easily disproved. it bewilders me someone would even make this claim and then attempt to infer it with global authority.

competent studio designers utilize soffit-mounted loudspeakers when applicable. It solves various inherent acoustical issues. Who are you speaking for here when you state they have "not been used for a long while"?? this is certainly not a "fact". this statement doesn't make any sense at...

random blocks of foam with unpublished mechanical properties. why not source Sorbothane feet/pads of which the spring/mass system can be tailored to the exact needs/specs of the loudspeaker that needs deocupling? simply source the size and associated "duro" value that has a lbs/pad range that...

RT60 is absoltely not valid/relevant in a bounded space of that size. no statically random-incidence, reverberant sound-field develops above the ambient noise floor. performing RT60 calcs here is a case of garbage in = garbage out. if the primary requirement is speech, you'll want to isolate...

distraction and deflection from the fact that you made a fundamental and factually incorrect statement regarding LEDE and RFZ studio designs. they in no way "eliminate the indirect soundfield". only Non-Environment design accomplishes that - and even then the room itself is in no way anechoic...

Toole's book and commentary on studio designs is in effect a "Circle of Confusion" unto itself - as so many i've interacted with seem to draw their "understanding of studio design" solely from Toole's commentary alone - when Toole's book(s) are not authoritative sources on studio design. and...

a quick/dirty method to understand if any mechanical transfer of vibrations is to couple your ear to the desk/work surface and have a friend lift the speaker up to perceive any audible differences

additional losses from edge diffraction

are these claims going to be substantiated with any objectionable, measured-data?

this pair of 708p's here probably have only been power-cycled a handful over times over the past couple of years. no issues as of yet. same for 705p that is cycled daily.

i think you're confused and/or don't quite understand just what the term critical-distance (Dc) entrails/implies. what you're describing above for simple modal resonances (eg, 100hz) is their inherent localized behavior. localized as in the pressure wave has a vector/direction component...

we need measurements, ie, objective-data that show that at a mere 1m from the loudspeaker in a "normal room" that the delineation of critical-distance (Dc) exists. and thus where beyond this (ie, 2,3-4 meter from loudspeaker) the indirect sound-field completely dominates over the direct. the...

is this something you-yourself have personally measured across a myriad of ("statistical", no pun) home, residential-type rooms and subsequently presented for peer review? or how exactly are you able to qualify this statement seeing as how it is contradictory against the work of Dr. Manfred...

kindly explain how the terms used in my past reply impart the need that i require to be explained at a basic level as to what critical-distance means and entails. and precedence effect is irrelevant as to critical-distance in the context of your prior statement. the field of acoustics is not...

interesting that the mfg for a a well-measured and subjectively high-performing loudspeaker is recommending (or not explicitly disseuded from doing so) treating sidewall reflection points with broadband porous absorption.
