Thiel Owners

Check my system page i put 2 photos of my new Coaxes.

I can tell you it's really worth the upgrade, my 3.7s have never sounded that good!!

Guys - about those 2.7/3.7 coaxes.

The black ones are the original chrome drivers that have been painted black. They are chrome under the black paint. They were painted to differentiate them from the early drivers which had erratic tweeter output levels which required trimming resistors to bring them into spec. When the tweeter level was solved, the 'finalized' drivers were painted.

If your chrome driver has no trim resistor, it is the same as the black ones. If it has one, then you might consider replacing that resistor with a higher quality resistor of the same value.

Of course it is possible that your old driver is not performing optimally, in which case having it rebuilt or replaced would upgrade performance. If Rob were to install a 'new' tweeter needing no trim, I bet you could get him to paint the frame black.

Thanks for the clarification Tom.  How do I know if mine has the trim resistors?  I have the Les Paul versions.

Pull the driver and if the wires go directly to the terminals, it is 'new'. If there is an electronic component on one of the terminals it is 'old'.

Rob hasn't mentioned any serial number record, etc. Many records were 'lost' under New Thiel.

If you 2.7-3.7 owners plan to keep your speakers forever it might be a good idea to get the new black Coaxes at some point, your Thiels will sound just like new.
