no idea, but user reviews in aggregate have got to count for something the 2022 thing is clearly off just from the existence of my currently deployed unit it is always possible to have a bad run, but in modern electronics and certainly audio and even moreso pro audio it is close to unheard...

no idea, and the design is loooong after my time, but certainly not noisy my (limited) experience I have used and still use one (well before '22) and have heard another one or two in use in the past, and zero noise, or at least if you put ear to tweeter and switched it in and out the v faint...

maybe I have already banged on about this; sorry if so single-position measurements are close to worthless and always have been (a windy screed on the history and the subject: https://ethanwiner.com/aes/david_moran.pdf) dips in the lower midrange are almost invariably due to the Allison...

boy, I think I get zero xformer hum (or anything else) from mine

I get exceptionally, universally praised smooth-sounding results the old-fashioned way, taking third-octave spatially averaged measurements (entails temporal averaging of course) using pink noise and an RTA set to Continuous or Average. There are several good smartphone ones; I favor the...

Nonsense. boy, is that complete bunk the best speaker engineer I know (worked with for years) and whose work I know (of many, like at the villchur, allison, mark davis level) just retired after 14y there, and voiced and tuned some sensational product I just visited the company (aes section...

It remains interesting that all of these detailed analyses of directivity mismatching and everything else problematic overlook first principles' principle 1: Does the design encourage staggered distances of the driver covering the lower midrange (say, from a half-octave middle C to an octave...

>> My memories of consumer units was that they were hiss factories. This is ignorant unless referring to the dbx 20/20, the company's first automatic equalizer, whose noisefloor was in the -80s and therefore potentially audible in use depending on the usual factors of gain stages, component...

See p16 here: https://ethanwiner.com/aes/david_moran.pdf (temporally and spatially averaged, unlike many)

this from 43y ago may be of interest, simplified compared w the above, but the same point, on p65 f2, and the pertinent text https://worldradiohistory.com/Archive-All-Audio/Archive-HiFI-Stereo/80s/HiFi-Stereo-Review-1980-08.pdf

People, It might be helpful to go back to first principles at least for 2ch stereo playback -- ? **All** speakers are omni to some extent and with some near uniformity up to some fairly high frequency (as in above middle C). Forward-facing designs (*NOT* 'forward-firing'; they fire in all...

Har and yes. A long time ago I quickly tired of the thin (hotly imbalanced) sound of my nifty new 'flat w a 4k peak' Etymotic in-ear phones, and so I turned up my broad bass tone control and turned down my broad treble tone control --- and ... eureka.

donor AND a major contributor! woohoo stay classy, dude

omg, I have never seen that before ! half-photoshopped, numbskull (btw)

>> does not have any phase control, only 0/180 polarity gosh, I wonder why that is !? I am kind of surprised at how uninformed this discussion is, except for a few posts
