To revive my old thread here I've made a few changes. I'm in the process of buying 2226's to put in my diy 4520's. I've got 3 but need one more. I did have a change in amplification though. I'm running a qsc gx7 to run the bass horns at 500 Hz and down to 40hz. I'm using a jbl 6260 to run my 2446's. I'm running it in 2 way and I'm quite happy. Still using a 2x4 mini dsp at the moment but I'm building a analog crossover. With the bass horns at 4 ohms the and puts out 1kilowatt and oh my god its so cool. Some songs can make my eyes rattle in my head so it makes my vision blurry buts its perfectly clean. I can sustain 120 dba at my listening chair, not that I do.
with the and running the bass horn now I need an even bigger amp to run the subwoofer when I decide what that will be. I've got a 2240 frame to build a 2245 but I don't think it will be able to compete. I've got space but not enough for dual 2245 subs. What's ever it is it will probable be ran by a really big honking amp. Well over 3kilowatts. I might need to run a 220 vac drop to my game room. Oh man I'm so hooked here, hehehe.
