Probably less than 1dB...not much. Another possible advantage of the parallel resistor is it will reduce the impedance of the tweeter circuit, which will in turn raise the tweeter's crossover frequency slightly. This may be desirable given the differences I mentioned above between the HiVi tweeter and the original. The parallel resistor is the first thing to try.

Thanks

I will give that a try.

Thanks Roy

Can anyone tell me what the dB loss would be using the 12ohm resistor across the tweeter terminals?

Some questions

With the switches on the back of the ar11s it looks like to reduce the volume in the mid and treble, the switch engages a 1.5 or 3 ohm resistor I think in series with the cuircut. If i put a 12 ohm resistor parallel to the tweeter I lower resistance (6 ohm tweeter looks like 4 ohm to the amp)and also lower high range volume? What is happening here? Im not an electronic wizard by any means so some clarification would be aprpeciated.

Thanks

The AR-11 already has an inductor across the tweeter, so no need to add another.

If you want the tweeter to look like a 4 Ohm resistance to the cross-over, you can mount a 12 Ohm resistor across the tweeter terminals, this will also bring the output from the tweeter down a little.

The power handling capability of the tweeter is adequate for use in the AR-11, since the highest frequencies has very little energy in them (relatively).
