Hi! I own Aguilar th500 with 2 Hartke hydrive HD112 cabs. My question is about cabs - on the backside they have a tweeter 3 way option. I don't really understand the response to the sound. I have always set them off, which means likely the tweeter is off? Anyway there are 2 more options 10 db high and 10 db low. How does it work switching it with my head eq options? It sounds easy, but i just feel i don't understand something. Please give some advises. The sound i like and put on my head is mids very high, lows a bit and highs a bit down.
