I’ve got the parameters in Xover Pro 3 and did the updates a while back. Are the T/S paremeters the same in the program or have there been some changes that I need to plug in so I can make a good xover?
No real changes since Nick at Lambda Acoustics designed them. You can double check to be sure with the parameters available on the forums which were updated by John, but it should be nearly the same.
As A9X said, 85L is for Q=0.707, and that would suit most people if it’s possible for you to have such a big center channel. You can always use stuffing to have more “space” if you can’t go that big.
By the way, it’s a good idea to use TD12S like in your mains, it will be easier to match sensivity and everything else ! 8)
