Hello everybody! I'm thinking about building my own CAB. My original plan was to use eminence B102 10" speakers to build a 8* 10", but after simulating it in WinISD it seems that it won't produce enough lows without the cone exurtion being to large. Today I'm using 4 Beta 10" in an old closed ampeg box, they sound great, but the real low-end is missing, so I thought about building a vented 8*10. I have looked around, and it seems that 8*10 are often closed design, maybe lower bass (I play in D, so about 36 Hz is what I want), and vented designs are more suited for 15"? Although I love the tight punchy 10" sound, maybe I need to reconsider? Lately I played some 4*12, and they sounded really warm and had more bass than my setup, so now I'm just confused!!! Anyone up for a more technical discussion?
