Default TB W6-789S "Almost" Full Range project

Excuse the cross post, but I thought some of you here on the full range forum might know this driver, the W6-789S from Tang Band.

I have a speaker project going, see this thread: The "FK" project
Using 2 TB 6.5s crossed up pretty high to a Selenium 1" horn. All 1st order filters.

Has anyone here had any experience with the W6-789s? Any tips or ideas about this driver?

These are on clearance now @ $26, I just picked up a couple, wish I could get more, but, need to measure them first...

How do you like them so far?

Hi,

The driver is used in the MCL :

http://www.partsexpress.com/projects...=MagnaCumLaude

Which seems to indicate all may not be well in the 1 to 2 Khz range.

The nominal specs indicate indicate good for lower power amplifiers,
but no doubt the 15W rating puts off the uniformed, not realising
that this indicates a lightweight voice coil (with its advantages).

TB measurements are fairly meaningless ands specs are ballpark.

TBH the "FK project" does not inspire much confidence, no BSC.

http://www.zaphaudio.com/Waveguidetmm.html

Looking at the above the FK tweeter c/o does not seem far out,
(comparing waveguide 27TDFC to DT20i PDF curves).
but the bass / midrange end its hard to see it working well.

Still, my main concern is the 1 to 2Khz range .....

1 driver models well in a 1cuft vented enclosure ....
