I plan to make or buy someone's non resonated CBE and make or buy someone's non resonated TP's. ill hear it out and then add the 18's I got yesterday off amazon if I don't like it. Ill listen again and if not to my liking still, ill pick up 2 12's and throw them in the TP's. since you have a Ti CBE I'd buy 2 12's which the resonator is only 9.5" long and have someone weld them into the TP's for you. Should make it sound a lot better.
