Some speaker driver measurements...

[danny_66]

Like the Isirs, I’ve been using separate bass bins for a decade now. I think there a so many benefits; both from a designers and consumers point of view.

I couldn't agree more

Yevgeniy how do you like the Puriwave?

I've finished my Purifi 2 way and very satisfied with it.

I finished the PuriVawe project in February and didn't have time to publish it in full. I hope to do so in the coming months.
I am also quite happy with their sound. Viawave tweeters are something special in terms of clarity, detail and softness. They are the best true ribbon tweeters I've ever heard.

It's called Paiyon DM6A-82-10P. It's not a copy of ATC but surely inspired. Poor motor by the looks anyway.

Le looks to high to me. If the FR can be believed the hump would actually make high pass crossover easier as well as lowpass. Expect 85-87 db sens when finished.

 

[piotr z]

It's unknown quality. Motor looks like 80's design. Same case was/is with ATC, while it's highly regarded and should melt peoples minds for me it did never do anything that special. With time after Zaph comments about Le i started thinking that high Le could have been the reason.

BlieSMa have anounced new 3" dome midranges:

I wonder if I could hear a difference when crossed under 3khz with 24db or steeper slopes when levels are matched. They all seem to work well below that point. Looking forward to the review!

The Al/Mg with the peak tamed would work quite well as a mid-tweeter for a small acoustic guitar/cello/bass amp. Paired with a Hypex plate amp and Purifi driver....clean broadband 110db peaks from a tiny point source package.

Prices have been posted on the DIY Loudspeaker Pad on Facebook for the Bliesma 3” dome mids with availability from Feb/Mar 2022.

380Euro for the Silk/Paper/Aluminium and 650Euro for the Beryllium (each).

Bit to rich for me (have to add import duty/VAT and handling, close to Volt 752 territory for the basic three) so will be sticking with the EM1308.

 

[Oneminde]

Well, we knew the Be would be expensive.. so..

 

[Scholl68]

It is indeed expensive, but honestly I was expecting even more for the berylium version, since the T34B is already around 400€ per piece in Europe, and has a much smaller diaphragm.

We will see if their measurements are worth their price !

 

[atoluma]

650€ without VAT so 780€ for european customer

 

[Zvu]

Pair of Volt 752 costr 1090 euros for a pair (VAT included).
Bliesma M74S/A/P will cost 920 euros for a pair (VAT included).

So a 170 euros cheaper per pair. it is worth it even if it measure the same as Volt 752 - though i do expect much better performance out of neodimium magnet and modern motor design

Better for less? Winner winner chicken dinner.

Has anyone seen measurements on the NS1000’a Beryllium dome?

Yevgeniy,

Your testing database is growing to be the biggest most thorough on the Internet. Thank you.

Where do you get your drivers for testing? Do you purchase them yourself?

Is there a way for Hificompass members to donate money or purchase drivers and have drop shipped to you for testing?

I’d like to see measurements on vintage drivers like XLS 850452, as well as modern Dayton RS225, W19NX, RSS390HF

Yamaha-NS1000

troels. The datasheet has it too.

I actually just got one of these. Sadly I think it is broken. It won't play loud.

 

[mainframe99]

Date tested should be added to measurements (apologies if i'm missing it)

 

[HeadShake]

Oh, I did that 5 min ago. Mic was 6" away and it is on a 24" X 24" baffle.

 

[Oneminde]

Could not resistance - they are out in the wild.

 

[tktran303]

Great!

Early Xmas present for us all?

I’ll test them Vs upcoming Purifi small midrange…

 

[audiogod66]

Could not resistance - they are out in the wild.

It's Lord of the rings- One(4) dome midrange to rule them all Golum wants

 

[tktran303]

One 125mm cut to test them all;
NE123W; PTT 4M, M74…

Maybe Yevgeniy can tell us how they sound and should best be used for all of us who can’t blow our covid spending money all at once…
