Some speaker driver measurements...

The measurements of ScanSpeak D2608/9130 tweeter have been updated (offaxis, step response, waterfall and THD were added):

I like that tweeter

Solid performer, I was using it until very end of passive systems fascination. Legend of those Peerless drivers from previous era, one of the best soft-dome tweeters ever made. Yes, it is still the same Peerless HDS P810921.

Is there any reason not to use that tweeter in an active system?

 

[Windforce85]

Where I said that not?


I just sold those loudspeakers some time ago and made different one.

 

[Charles Darwin]

It was sort of implied that there is a reason to use another tweeter when you stopped using passive crossovers since you also said it is one of the best soft domes ever made.

 

[Windforce85]

Bad semantics, I'm sorry. Every driver which is good in passive system will be also good in active system. This assumption often does not work in reverse.

 

[Charles Darwin]

Fair enough.
Thanks for clearing the (my) misunderstanding up.

many seems to like this tweeter, but i do not. it has to much dispersion me think, it sounded bright and i had much trouble to tame the response up to 8khz, i gave up and choosed a s-s ring radiator insteed, much better

These days I wouldn't use any tweeter without a waveguide.

Is it possible to add the results for the Seas 27TBCD/GB-DXT to the list of driver measurements?

 

[454Casull]

Also, may we see the SB Acoustics SB65WBAC25-4 as an upcoming driver for measurement?

While you're waitng - John (Zaph) Krutke tested it HERE, Goran tested it HERE and Mark K. tested it HERE. It's a very unique tweeter.

HiFiCompass already tested the tweeter (he included a link earlier in this thread) but the page with all the tested drivers does not include this tweeter.

Oops... Have fixed it

Not for a while...

Would did that if I have it...

Thanks, they know how to make good drivers. In SB, even plastic can be good.

IMHO this midwoofer (the SB15MFC30-4) and the larger SB17MFC30 version are well executed poly cone drivers that can be purchased for a reasonable price. Not top of class in any one category, but good performance overall and easy to use (I use the SB17MFC30 as a nude dipole midrange).

BTW, thanks for continuing to publish your measurements. It's a luxury for DIYers to have access to a consistent set of data for a wide range of drivers! Kudos.
