Anyone used the Tangband W3 1285SG?

Just spotted it- good looking little driver- big rise above 10 khz

I'm looking at those drivers recently - the "3 and 4" TB's

What my eye sees is that from 10 kHz to 20 kHz the rise is about exactly 12 db.
And from 10 to 20 kHz it is exactly one octave...

So you could try a second order low pass filter - 12 db/oct

But someone with more experience should tell whether you should calculate the values of C and L using 15 khz (-6 db) as a crossover point - If I state that I might mislead you.

Otherwise the SPL looks pretty good between 300 hz and 8-9-10 khz it seems to be +/- 1.5 db - if I see is correctly it's minimum is 85 db and it's maximum is 88 db for that range - pretty impressive.

Now as I look more carefully the 12 db gain is between about 8 khz and 16 kHz - again one octave.
-6 db point should be at about 13500 hz, someone else should tell us what crossover point that corresponds to and what Q crossover/slope should be used - Linkwitz, Butterworth or Tchebishev...

That's from me and thanks in advance to the one who explains the needed crossover point.

great driver, only weak in bass. one of TB's finest imho

and with regards to the rising high end: just listen a bit off axis and all will be fine

Henkjan does it need Notch Filter?

Good to know they perform well, they look like they should. How far off axis? anyway, a little rise is a good thing for large rooms imo.. if I use, I don`t want anything in signal path other than 1st order.

10deg was enough

I had a RCL in the Needle (can't find the values, sorry). with another baffle maybe not?

just 10 degrees toe in? great! My first choice was the alpair 6 but the surround is far too wide for my build. How do you think the sound compares?

[Henkjan]

[disclaimer: this goes from memory of a couple years ago]: the Alpair6 is more neutral than the W3-1285, the TB has more crisp. what you like more in the long run I can't tell, I did not have the speakers with the little TBs long.

one important thing: the TB really needs a woofer, it has virtually no capability for bass. it really is more a midtweeter than full range. The Alpair6 (given the right cabinet) can give you full range (at moderate volumes of course, it still is a small driver)

btw: if you can get hold of a pair of the square basket Alpair6s, you should be able to squeeze them in a slim space

cheers, thats v interesting. I want a crisp sound. I will use a 1st order so little to no bass duties for the full range drivers, 2 each side and stereo 'subs' underneath
The enclosures are 'bullet' shaped, hence the need for a small diameter unit.. it would mean hack sawing the edges off the alpair 6 to fit.. not something i want to try.
On the images of the Tang band, there is a shiny glue(?) 'ring' on the rubber surround- does it make it a bit cheap looking?

[DYNABLASTERTUNERS]

for me this shiny ring makes it cyber high-tec looking the downside is that it's "sticky" for dust
