Before I buy everything I want to make sure this is all possible and will sound good. I'm planning on builing line arrays with 16 toal 7" Dayton Ref mids so 8 per tower. I also plan on using 1 Fountek neo5i ribbon with each tower. I plan to power all the mids with a behringer ep2500. What do I power the ribbons with? For the center channel I plan on using 4 5" Dayton Ref speakers with 1 LCY ribbon. I was hoping I could power the center channel and the rears with the receiver. As for the rears I was thinking maybe another dayton 7 and a tweeter. I'm getting custom 15" subs built for me so I've got all that taken care of. I still haven't found the receiver I'd like to use. Want to spend upwards of $500. I'd like a 7.1 so I could upgrade later. Also I know I need custom crossovers but I have no clue on how to make them. Is there anyone that could design some for me. I could build them just not for sure on how to design them is the problem. This is going to be used for Movies, and Music. This will be my first diy ht system so please let me know if something isn't right. I just don't want to spend all the money on everything and then find out it won't work or something won't sound right. I know this is my frist post so if this is in the wrong section I'm sorry and move it to where ever it needs to go. Thanks.
