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

The driver is used in the MCL :


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.


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 ....
