Somehow that made me think of this:

BTW - just browsed PartsExpress and noticed that the white TG09 is now available in both 4 and 8ohm versions. Price has dropped some too apparently, the TC09 is like $12 and the TG09 is $16.

I am tempted to rethink the choice of drivers despite having the TC09´s on hand already...

My experience would have me going for the TG9. It is fine… i am not a fan of the TC9.

like those, only taller, much taller
and with lines of 12" woofers on 3 sides so it can play Thus Sprach Zarathustra with authority!

I have thought about that, on more than one occasion. I was willing to spend the money, but in the end, I feel that the actual room + processing matters more than the switch between these drivers.

After all, we draw are own target, don't rely on a driver + box to do just that. People who have played with a few different EQ methods and targets should have heard large differences even from the same drivers. Heck, even small changes can have huge influences to our perception.

The TG9 8 ohm is an interesting driver though. I wish you good luck with making that decision (lol). I'm sticking with paper.

We should more than know you declare not to be a TC9 fan : ) that said think your TC9 nag is probably nothing but a old objective war with xrk971 and his great work publish objective research data for varius tranducers, think to guide Halair about TC9 verse TG9 it would be much more fair look serius at those transducers objective data in a compare rather than use your subjective opinion for a driver that seems nag you so much you probable never get over it.

Lets look up the published data in a compare and then please tell why you recommend TG9 over TC9, myself recommend TC9 and reasons is bit higher R(e)/lower L(e)/better thermal power/better sensitivity/lower M(ms), in my book TG9 only wins on the lower f(s) point and little less impedance swing on the resonance but mind you that TC9 is also exstremely low on resonance swing if we compare to most other tranducers and probably a point that combined together with the exelent L(e) makes it sound so realistic because every wiggle from pure flat on impedance graph will add a bit of phase distortion because transducer is a current device and power amp is voltage device.


In below both are modelled in a 4 liters volume because that is probably close to the virtual volume number where Halair end up, also T/S parameters are listed.

Now lets trace these two public graphs for TC9/TG9 over into VituixCAD.

I am at home with a fever so I´ll read / absorb the TC/TG info later

On a more pragmatic note, I pulled out my bigger camera in order to try to provide the "better" image, as the first array is now standing on its own:
