Appreciate it if you can let us know the artist and title. Thanks.

Why do these people need passive radiators?))

I'm not sure how that is related, whether you use a passive radiator or port, you can clearly under 80Hz the distortion is rising quite fast and therefore would benefit from subwoofers

The track list I have is created for testing both speakers and headphone. The specific track for headphone here is one that brings out spatial qualities of the headphone. When I have played it on recent speakers, the bass sounded distorted. The improvement that A6B brought was deeper extension which kind of made up for the quality of the reproduction at higher levels. Here is the track:

I have not played it on my Salon 2 for a long time but I had found it and added it to my playlist due to quality of reproduction on those speakers.

Let me know how it sounds on your speakers.

Sorry to (briefly) sidetrack this thread, but I love me some female Norwegian jazz singers. Check out Silje Nergaard's It's Gonna Rain off the For You A Thousand Times album. Might be another test track for you. (Volume is lower than the youtube track you posted, so don't be shy about turning it up a bit.)

Sorry, but I die a little bit inside when someone doesn't know who Frank Dernie is.

Frank Dernie - Wikipedia

en.wikipedia.org

Thank you for the Wikipedia link outlining Frank's carreer, obviously a legend in F1, and I'm an ignorarmous. By chance I went to the first Australian F1 in 1985 in Adelaide, that was won by a Honda FW10 designed by Frank and Patrick Head.

From Chat.GPT

QUESTION: "who won the first Australian FI in 1985, and who designed the car"

ANSWER:

The first Formula One race held in Australia was the 1985 Australian Grand Prix, run on 3 November 1985 at the Adelaide Street Circuit in Adelaide.

Race Winner​

• Winner: Keke Rosberg (Finland)
• Team: Williams F1 Team
• Car: Williams FW10

Rosberg dominated the race, starting from pole position and leading most of the event to secure victory in the inaugural F1 Australian GP.

️ Car Designers​

The Williams FW10 was designed by:

• Patrick Head – Williams technical director and chief designer
• Frank Dernie – Williams aerodynamicist/engineer

The car used a Honda turbocharged V6 engine, which was extremely competitive in the mid-1980s turbo era.

So not all information produced by AI is useless and I have used it to assist me for many things including:

1. successfully designing a 18.5KW Solar installation with a 40kw battery in a heavily shaded location on 3 different roofs with different slopes
2. understanding the implication of tax changes to Superannuation in Australia
3. analysis of our tank water report
4. greek sailing holiday ....

However, when travelling I was concerned about the lack of rain on our property and checked the BOM, which said there was no rain. I then rang a neighbour who advised me it had been raining for past 24 hours. It turns out the BOM site was being upgraded. Garbage in garbage out will always apply.

Aplogies for the off topic but I find AI incredibly useful, however, the expression "Buyer Beware" applies. Certainly would not use it to purchase audio gear, where ASR is the gold standard.

Because LLMs get some things a bit right sometimes doesn't mean that your hallucinations that they are in any way trustworthy correct.

 

[xanalog]

AI is breathtakingly wrong in my speciality.

But you can make AI breathtakingly correct for your specialty.

 

[Grimoire]

But you can make it breathtakingly correct for your specialty.

Arrant and dangerously arrogant nonsense.

 

[amirm]

Let's not get into AI arguments folks.

 

[BeeKay]

Things wouldn’t get mixed up if it had been marketed correctly from the beginning.

MMI - mathematics mimicking intelligence

But then we would miss another financial massacre, when this bubble may burst.

 

[Oink-Oinko]

Definitely not a hard elbow. But a lot of high performance speakers do this - Neumann, Genelec, etc - all do this to get a longer port in a small box.

Would you say Kinda basically like a seudo T-line port ? ?

 

[Lars Risbo]

I'm not sure how that is related, whether you use a passive radiator or port, you can clearly under 80Hz the distortion is rising quite fast and therefore would benefit from subwoofers

not sure if you saw the the distortion graph i posted on #206? stays on the 1% range down below 30Hz up to 101dB SPL. This is dual 6.5” and a port (straight- bends would not do this). Not all subs can even match this and the integration is hard to do right (my experience from walking hifi shows)

 

[Lars Risbo]

Hey Amir, this is a nice distortion graphic but I wonder if it would be beneficial to have a similar one with a 2nd order high pass at 80Hz in place, since I suspect most people are using subs these days

you can simply just look at the graph from 80Hz and up and ignore what is below. no need to high pass for that (except to protect the speaker during the test - I had a 20Hz high pass for the seeeps in my post#206).

this is for measuring sinusoidal single tone distortion. for multitone, a highpass will make a difference (limiting excursion which reduces IMD)

 

[Endibol]

I asked Chat GPT, and they said that lowering the dB reduces acoustic energy, but that there's a high risk of losing subtle signals as well! Ask Chat GPT yourself. If you reduce 86.8dB to 82dB, is only acoustic energy lost? What else is lost? Ask them this question.

 

[EDMoser]

IDK. For my $4k I'm going with a system with one or two subwoofers to achieve full-range response and low distortion in the bass region.

I can’t find this track on any of her album/EP releases. Is it a specific live performance on YouTube that’s being referred to?

No, it is just a regular album called "Winter Songs (Icemusic)." Here it is on Bandcamp for download if you can't find it elsewhere: https://terjeisungset.bandcamp.com/album/winter-songs

[Audionaut]

Going into this review, I was kind of depressed. I an not into, "more expensive parts mean more performance" as some of you no doubt know. Those parts have pushed the price of this speaker rather high.

Yes, if they are only more expensive and do not offer any improvement, I agree with you. However, the Purifi speaker chassis offer a few innovations that can be measured and heard when they are properly integrated into the overall speaker.
In this respect, you unfortunately have to bite the bullet and pay the high price to enjoy some of the best speakers available.

 

[Frank Dernie]

But you can make AI breathtakingly correct for your specialty.

Not without revealing things it took me decades to learn and few people know. It was why I was pretty well paid

Hi Frank, I use AI for different things, and often find it useful, however, I always review it's responses with a healthy dose of skepticism. I agree it is often wrong in areas where a lot of subjective information abounds such as HiFi.

Can please I ask your area of speciality.

Formula 1 car design and exploitation.

 

[Flaesh]

I'm not sure how that is related, whether you use a passive radiator or port, you can clearly under 80Hz the distortion is rising quite fast and therefore would benefit from subwoofers

Maybe passive radiators aren't necessary, and a single driver is sufficient for 80 Hz operation (??). At least, I use a simple sealed box with a single speaker driver above 80 Hz; subwoofers operate below that.
A6B seems to be designed primarily for use without a subwoofer.
