I have a pair of them and some 16xx series, but I forget exactly which and they're in a box ready for the house move so I'm not going to check.
The measurements of the SEAS CA26RFX (H1305-08) 10" woofer have been added:
SEAS CA26RFX (H1305-08) | HiFiCompass
SEAS CA26RFX (H1305-08) | HiFiCompass
Thank you for the compliment
Some speaker drivers I purchase myself, some comes from my friends, some from my customized loudspeaker projects and another ones from companies which sponsor speakers for reviewing.
The best way to help me is to purchase new interesting speakers and send them to me for testing. This way will benefit for all diyers!
I'm sorry, but don't have access to the woofers you are interesting in (850452, RS225, W19NX and RSS390HF)
Unfortunately, PayPal doesn't work in Ukraine for receiving money, just for their sending
I don't know simple solutions for members which would like to support my efforts
HiFiCompass,
You are providing a very good service to those on this forum with Speakers Drivers measurements data.
Looks like you live in Ukraine, and there is rising political tension in your country with Russia, so please take care of your family and yourself. My hunch is the tension will diffuse in the near future.

Sucks that some of the nicer Vifa small-format tweeters are getting harder and harder to source. NE19VTA has been gone for years, NE19VTS is almost gone now, the old D26NC55 was discontinued like a decade ago... all great performers in a tiny package.
Even OT19NC00 is unavailable now but I suppose that is because of the pandemic, not a conscious decision to discontinue.

Yevgeniy,
What about Transferwise? Recent name change to Wise.
I used this company/service myself when I was living in Canada and sending Australian dollars back and forth to myself. Better than PayPal. Last I checked it is supported in Ukraine.

What's the reason for not including voice coil current measurements?
Just curious.
And yeah, please stay safe and all
I used transferwise in the past, my GF still uses it on a monthly basis, works great

Just wanna use the opportunity to inform that Peerless has updated their 6.5" HDS woofer datasheet and some of the values changed. Too bad this driver and its 5.25" cousin is currently not present in HFC database.
Simulating the old and new 6.5" shows some losses at 20Hz for the new one, but we gained better values.
Cms went from 0.698mm/N to 0.464mm/N .. so a tiny improvement.
Le was 0.43mH and is now 0.467mH .. a tiny decrease but not much.
Qms was 3.12 and are now 2.45 ... so an improvement which ties into the Cms change.
Qes was 0.44 and are now 0.516 .. a slight change but nothing drastical.
Qts was 0.39 and are now 0.43 .. so a smidgen better.
Fs changed from 46.2Hz to 56... you might need a new cabinet and/or port.
While the changes aren't super dramatic, they are enough and if the suspension got a bit stiffer, we should see a tiny change in distortion measurements. I wanna test the new 6.5" against SB17NRX2 and Discovery 18W/8434G.
They cost roughly the same but one is not like the other... paper vs two glass fibre cones
You can view the changes in the attached PDF's

Yevgeniy,
Yes. Please do some due diligence and if you feel comfortable setting up a Wise account, I shall transfer you some funds in time for the holidays. Driver testing is great, currency is better. Hopefully others can support you. And feel good for doing so.
Happy Festivus for Yevgeniy and HifiCompass users!

Right, the Qts on the HDS-P830883 which you talk about is close to the ideal of 0.7 for open baffle/dipole loudspeakers. The Cms is also very tight at 0.240mm/N. Only issue I see from here is the 7dB peak at 4.5kHz as the "main issue", but should be possible to XO out. Le for this driver is also not too bad at 0.21mH.
I noticed it on the HDS 5.25" as well. I think I will test, measure and listen against ScanSpeak 15M/4624G. Looking at HFC's library of midrange-woofers, the 15M is an underdog.

the Dodo is a bird which went extinct and I agree, for some reason, the HDS driver(s) are overlooked by DIY'ers ? They can't be that bad since SVS and PMC are using them and I heard the PMC Twenty.5 some years ago.
