Hi folks, I'm building a vented cabinet to be powered by a GK MB-500 which delivers 500 W at 4 ohms and 350W at 8 ohms. As I'm building just one cabinet I want it to have a load of 4 ohms to get maximum power of my amp. To be clear, I was actually building just a 2x10 cab but after some research I found that the BP102's wouldn't offer satisfatory mid/treble so the Alphalite 6A would be a great complement. Also it would put cab's power to 500 W. I already have the BP's and the amp head. I need assistance in the following topics: -How to wire (if it's possible) these 3 drivers to get 4 ohms? -If I was building the 2x10 cab I would wire in parallel directly to the speakon jack. Considering the third speaker should I use any crossover or filter (how necessary is it)? Some specs(ran on WinISD)of the cab you guys should consider: -Vb~5.3 cu.ft -Fb= 42 Hz -2 round shaped vents, Dv= 4 inches, Lv= 4.5 inches -One Speakon jack -SBB4 alignment Feel free to offer other shape/wiring/dimensioning options considering these 3 drivers in question. Thanks in advance guys!
