Yes, everythings working great, has to be the best bass I have heard in my room, very defined. Death metal sounds absolutly sick, drumming comes through great.
I had to get rid of the filter on the THT it was causing a weird FR in room. The THT is definately more efficient overall and can play deeper than the 18 sound with less THD.
I also got rid of the harshness in my mains with a new crossover design.
