Thanks a lot Ulrik ... the tweeter seems to use ferrofluid?
Btw I still have some doubts of the long term stability of the flexible leadout wires in the new 9.5 inch Textreme driver , the gluing is too wobbly!?
How about using thin/flat copper strips for electrical/mechanical connection? (or CuBe2)

And it would be nice to have the tweeter replaceable!

For this dream driver from SBA I would like you to listen to this album the remastered version is really good and it has even real human hand claps in it (1st track) , not this rubbish annoying electronic stuff!
Just checking tracklist is in error this one misses and is teaser #2
wait for the voices coming in very impressing stereo effect :

There is no ferrofluid in the tweeter (the axis range just makes it appear that way, as it was set to show both impedance curves in the same graph, and the midrange driver has a much higher maximum impedance level at its reconance frequency).
The tweeter is replaceable.
We haven't encountered any problems with the leadout wires, but I will keep your comment in mind.
Please be advised that this is a midrange/tweeter coaxial driver (i.e. not a mid-woofer). Despite the fairly low resonance frequency of the "woofer", it is not meant to be used at the lowest frequencies, due to limited excursion capability (this is a deliberate choice/decision). It will easily operate down to 70-80 Hz, though, so you can pair it with a subwoofer if you like (or you can cross it over higher, of course, and use it in a more conventional design).

Thanks for your fast reply ... good to hear NO ferrofluid is used , sometimes it's unstable so I try to avoid it in drivers especially when having an elevated price .
Replaceable tweeter is a nice option that makes me thinking about a mech. decoupled tweeter ... (not sure about being able to hear a difference) .
Thanks again for spending your time!

Lead wires are always braided multicore for a reason, mechanical fatigue..
What do you think would happen with your copper strip over time and repeated use, bending it back and forth.
work hardening, fatigue and then rupture/fracture.
The same reason solid core wires are outlawed for use on ships, continious vibration makes them break over time...

It can't be that low cost. The R&D, the thick and well braced and finished cabinets, and the drivers stack way beyond that. This doesn't even include overhead and profit margin, but I would wager the cabs and drivers to easily cost 1500 USD to make at retail cost. Using the 500% markup for the rest and being conservative at that, comes to $2250. The conversion to euro or pound comes to 1800 or 2100, give or take.
I could be off the mark, but then hitting the more typical 1000% markup, hits the$3k mark quite easily. It's basic economics and how to run a business.

sorry no flat strips are widely used for decades it is when done right the ultimate solution and CuBe2 is the best conductor for the job!
nevertheless if conditions are not so hard then 2nd class stuff will do the job also pretty well .... if we had a transducer engineer from one of the bigger companies then we had a better source of information but usually they keep their biz and trade screts ... a good source for start is the LIS from audioxpress.com
