Yes, it is correct. My T-IVa ribbons measure 3 ohm. I have new spares and they are 2 ohm. With just 2 ohm the sensitity will rise, if the power amplifiers cope, the 1 ohm resistors takes it back to a similar level as the original 3 ohm ribbons. Another way would be to use longer strips of aluminium as cables for the ribbon tweeter. The spare set comes with three ribbons, it is posible to use one of them splitted in two as 1 ohm resistors.... I Think Apogee had some strange looking series resistors of aluminium foil in the Scintillas, also raising the impedance and lowering the sensitity.
