    Objections to speaker qualifications

    Those links show exactly the problems and limitations of full band implementations, I have used such dodecahedral sound sources for acoustic research measurements, they are typically used in combination with reverberation chambers to approximate a diffuse field.

    Objections to speaker qualifications

    As said also from others here that doesn't really work vertically due to its size and nature of bending beam modal behaviour. A real close full band 2 pi omni source is quite impossible to implement, for tweeters (for example Plasma) and woofers it might be possible but due to their spacial...

    Objections to speaker qualifications

    Similarly to the MBL's they aren't true omni but at best axially symmetric in the horizontal plane, but are definitely not vertically.

    What is your favorite house curve

    The effort with multi subs etc is done to get smooth bass all around the room, at a single position you can fill also dips with EQ but usually this means peaks in other positions which can degrade the reproduction quality. Also such RTA measurements don't show for example the decay times and our...

    SVS Ultra Evolution

    Not that it matters but my hobby/fun DIY constructions avoid such obvious directivity mismatches, if I had a loudspeaker company I wouldn't bring out such a compromised design at that price, especially since it could have been improved easily without higher cost. But as said that doesn't...

    SVS Ultra Evolution

    The criticism is that a better engineering with better tuning/crossover, more matching mid, tweeter and or waveguide wouldn't really have driven up the price. Just using large/heavy/expensive components doesn't guarantee anything. The impressively low distortion in the bass doesn't help much if...

    SVS Ultra Evolution

    Quite a disappointment for me at that price and size especially in terms of directivity and multitone distortion at the tweeter low end: Full review and measurements source:

    What makes speakers "disappear " and can it be measured?

    Interestingly Pearljam5000 created the "new" thread exactly 3 years and 1 day after he had created the original one, let's see what happens in 3 years from now. I am betting that he still won't have bought any loudspeakers and keep asking the same questions.

    Dali Zensor 1 Spinorama measurements (passive version)

    What impresses me is that even their entry series drivers seem to behave well in terms of distortion.

    Differences in Klippel NFS Measurements Based on Enclosure Thickness and bracing

    As it doesn't appear on all axes (and thus changes also the directivity indexes) equalisation wouldn't lead to an identical result as its "monodimensional".

    New TAD CR1TX flagship speakers

    EAC has uploaded the review measurement already but not the written article yet, so for now here is just the spin screenshot:

    Worst measuring loudspeaker?

    Yes, they really sound as bad as they measure, I had the "joy" to listen to them at several audio shows, here I had written about it: I have nothing against exotic concepts...

    Revel W228Be In-Wall Speaker Review

    As all Revel offerings it shows fine technical performance and tuning with main competition coming from KEF, for example measured in a lower price range or in a similar price class

    AsciLab speakers are about to launch

    I prefer the directivity of the Neumann a bit more but that is still nitpicking on the highest level:
