Here is a question of a more practical nature.
This is in regards to the GR-Research OB sub, plate amplifier (Rythmik Audio).
On the plate amplifiers, when using "High Level In" how does the signal go to the Mid/Tweeter assembly?
Do I need to build an external crossover/splitter to do low pass to the woofer section, and high pass to the mid/tweeter assembly?
In a perfect world, the High Level In would be an in & out, but either more binding posts would need to be added, or there would need to be two models, one for a sub per speaker, and one for a sub per pair.
Of course I suspect having a high level variable crossover would be an interesting engineering trick.
So if I must have a fixed LF xover can I just do a high pass to the mid/tweeter section and the "crossover" on the plate amp would handle the low pass?
