FWIW, those transformers won't produce anything like 30W at the lowest octave. The Hammond frequency response graph (which is already down >1dB at 20 Hz) was produced at an equivalent output power level on the order of a few mW. Based on their size, it's likely these transformers will saturate around 6W to 7W at the lowest frequency. That may or may not be sufficient for the Altecs. Just wanted to point this out as something to consider before you start your project.
