Awhile back there was discussions about adding a resistor in series with both the tweeter and mid-range speakers on the 2.7 coax speaker .
I was communicating with Rob and he suggested using a 2.5 ohm resistor and had heard that 2.7 ohm sounded good , another Thiel owner said he used a 3 ohm resistor and like the sound .
I listened for weeks and then took them out and my opinion is without the resistors in sounds better. or even a lot better . While with them there were songs songs and a few early 60's the benefited from the damping of the higher frequencies but when listening to all music it sounded more 2 D or a flatter and narrower sound stage .
I curious what using a lower value resistor would sound like .
