Amplifier output question

[Tube Radio]

I've got a Magnavox AMP-142 where I had to use an Edcor audio output transformer as the original was not there. It has 4 8 and 16 ohm taps.

I currently have a three way open baffle speaker connected to the 4 ohm tap.

I may add an open baffle woofer to the amp.

If I install a high pass in series with the existing woofer of the three way and a low pass on the new woofer, can the woofer be connected to the 8 ohm tap provided I cannot find a 4 ohm woofer that will work open baffle?

You can do whatever you want. Results vary.
Try XSIM to experiment with crossover design.
Free and a fast learning curve.

The crossover I have no problem designing.

It's just that I don't know much about using two taps on an output transformer with one feeding a high pass and the other feeding a low pass as I've never done that before.

I can't think of any reason why it would not work.

I figured it might work given I am using an actual crossover, but had to make sure.
