J.R. What are some of the variable that would make using different amps difficult in a multi-amp configuration? Once of the reasons I'm interested in active XO and multi-amps is being able to match amps to the frequencies that they perform best at. I know that different amps have different gain, but take can be adjusted for with attenuation at the XO stage.In terms of the SE example I gave, it was specifically designed as a low cost project and used Hammond's 125SE output transformer to save cost. I've never heard this transformer, but I'm sure it sounds perfectly fine within its specified range of 100Hz to 15KHz. A fullrange transformer would have cost more than double. The design does raise the good point of cost vs performance. If you know the amp's only going to be used in the midrange, is there a need to spend extra money for fullrange?
