For subs I currently have 10000 watts of power running via a Lab Gruppen 10000Q PLM amplifier to my custom made 15"x8 drivers (4 sub cabinets). These produce a staggering amount of bass with about as decent of an in-room response as you are ever likely to achieve. They will be mated to my new Trio's coming in.
There is a ship carrying my Trio's across the Atlantic Ocean right now coming in before thanksgiving.... will post more with pics once it is all setup next month.
Sounds good to me! Congrats
What type of drivers will you be using for the bass cabinets? Pictures?
Remember to let the bass speakers blend in from around 140-150hz, the Trios will not have much output under 140hz in almost any room.
