Hi guys. I'm hoping someone might be able to help me design a ported 1299 center. My current set-up is 1099 for LCR and HTM's for surrounds, with 4x mini marty's for subs. The front space looks like this:
I'm thinking I would use the standard baffle that comes with the 1299 and add a few inches of width on either side to accommodate whatever port size is appropriate, as illustrated in the super high-tech computer modeling below:
The room is 100% HT and always used with subs (center is currently crossed at 80). The room is 20 x 21 x 12 and open in the back and MLP is around 13 ft from front wall. My specific questions are:
1. What box size should I be using? I'm guessing height will be 14.75, width will depend on port size, and depth will be whatever is need to be achieve necessary box volume?
2. Given whatever box volume is recommended, what port size should I be using (I have no tuning frequency in mind and would appreciate your guys direction on that as well, particularly when it'll never be used without some very capable subs)? I see port tubes come in every conceivable internal diameter and length.
3. Finally, will I need to alter the crossover to accommodate the move from a sealed to a ported design?
Thanks for tolerating my questions, and thank you very much to anyone who could offer some guidance!
