This is why we only buy the newest PMC actives, they're categorically less of a mess. Still some bad TL interference though.

PS Audio aspen FR10 Loudspeaker Lab Report
Lab Report While the midrange FR20 model [HFN Apr '23] is not unlike a scaled-back FR30 [HFN Jun '22] in design and performance, the new FR10 is very much 'its own man'. For example, while the FR20/30 crossovers are engineered to achieve a 'flat, nominal 4ohm impedance curve', the FR10's load...

The scale is more zoomed tho' : 70-100 dB vs 50 - 100 so less bad than first glance .PS Audio’s smallest reviewed by Adam Smith for hi-Fi News.

I don't think this belongs in this thread to be fair. The format/scale of the graphs from hi-fi news is horrible, I don't understand why they show it like this. It's a bit uneven, but doesn't look to be far away from +/-3dB between 50-10khz.

I agree, not awful, I don’t know why Hi-Fi News uses this scale either.

Voxativ Ampeggio 2024 loudspeaker | Stereophile.com
Evaluating a loudspeaker that would become Stereophile's 2011 Product of the Year, Art Dudley, at the time the magazine's editor-at-large, wrote, "The Voxativ Ampeggio went beyond sounding good: More than once, with too many records to mention, I found myself stopping to marvel at its...

I’ve always wanted to hear the Voxative speakers. I found single range drivers speakers like that can have an intriguing sound. Hopefully at a future audio show I guess.

I can’t imagine that sounds great. Very little bass below 140Hz, 5dB peaks at 2kHz and 4kHz with a -5db null in between; then a 5db peak at 8kHz that turns into a 10db peak at 10kHz, followed by 30db drop around 12-13kHz.
The off axis response is just as bad.
Compare this to what you get from the D&D 8C at around the same price and it’s actually funny.
Literally the only thing this speaker has going for it over the 8C(or Kii) is the point source dispersion, which in theory should provide a better vertical response, tighter imaging and a more coherent soundstage, but given all of the off axis flaws, I’d bet those speakers stomp it on that front too.
Speakers like this make me want to purchase them just for the sake of making more interesting 3 speaker blind shootouts, but it’s so expensive. Would be fun to put them in a shootout with a JBL 308P. My money would be on the $300 speaker.

In terms of single driver speakers, I’d love to see measurements of the Sibelius. Those speakers have been given quite the recognition amongst YouTube reviewers.
That said, my expectations of them are low.

Understood.
As I’ve mentioned before, it all depends on ones on approach to the audio hobby.
If you’ve decided on certain features you like or desire in your loudspeaker - e.g. flat frequency response on a certain type of dispersion - then you can filter out speakers like by that criteria as a “bad speaker” that you don’t need to bother with just by looking at the measurements.
On the other hand if, like me, you are not seeking just one type of speaker sound, but enjoy the way speakers sound different, and find that entertaining, then even such speakers as these can be a curiosity.
I had a nice sit down with some Rethm speakers, based around the Lowther-type drivers. What I heard tonally tracked quite well with the Stereophile measurements:
Sidebar 3:
(also when I heard the Devore 0/93 speakers that tracked pretty well with those measurements too, and the comparison).
Nonetheless, I was really glad to have heard those speakers. I found them lacking in warmth and body, and slightly gritty sounding in the treble as Art Dudley did. But there was a neato spaciousness and airiness to the sound, a real solidity of imaging, and a particular density and palpability to the sonic images, even though they were leaner than I would like.

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:
Expensive loudspeakers that sound bad
Raidho speakers measure quite poorly in most parameters except perhaps distortion but I've not listened to any. I have heard big and small Raidhos. I always found the sound to be horrendous, truly terrible, especially in the low frequencies.

I have nothing against exotic concepts like wide band drivers or large horns when implemented well, I even enjoyed some Avantgarde Acoustic horns at shows.

Sometimes I mix up voxative with the Cube Audio Nenuphar speakers that I want to hear hear. Somewhat similar designs with the QA extends the base and I seem to remember measures more evenly. I can’t remember where I saw measurements maybe I misremembering.
That link to the earlier post had some comments by Art Dudley on the voxative speaker. I really like Dudley‘s writing, but he also managed to sometimes say some pretty opaque - if not outright silly - things about speakers and his descriptions.

There really hasn’t been anything that awful recently thankfully B&W ( as so often) have ended the drought with this ‘signature’ 805.

Can they do worse we wait with bated breath.

When distortion is low enough and using dirac or audyssey to iron out the FR I see no big issues using this speaker.
Looks fine to me. Like adding a subtle bit of loudness contour, which will sound good at low volume.

You "cant" EQ speakers that also has bad directivity which are also a B&W treat
fr changes above the transitions frequency should be done subtly and carefully .Speaker with better directivity are more suitable for EQ .
Well it would work to some extent ( considering how shrill it must be now ) , but the discrepancy between direct and indirect sound is still there EQ applies to both .

Bowers & Wilkins 805 D4 Signature loudspeaker Measurements | Stereophile.com
Sidebar 3: Measurements I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the quasi-anechoic frequency- and time-domain behavior of the 805 D4 Signature in the farfield. I used an Earthworks QTC-40 microphone for the nearfield...

Worst measuring loudspeaker?
Jebus! Who thought this was a good idea? Gershman Acoustics, apparently. Never was very impressed with their speakers when I heard them. They seem to be getting more press these days, though. This is one of the few "bad" reviews where you don't have to read between the lines...
