Greetings, I have an Eden D118XL that with my current amp is only getting about 235 watts. The cab is rated at 500 watts (8 ohms). If I can get more watts to the cab (i.e. buy another power amp) will the extra ~265 watts make a big difference? I know it will make some kind of difference, however I feel that the speaker is not loud enough and I'm not sure if that's because I need another 18 inch or because I need to give the one 18 i have now its full wattage. So what would you do to get louder, while keeping $ cost at a minimum. a. Give the cab the full 500 watts or b. Get another 18 inch speaker, and not necessarily max out either cab's power rating. Basically this boils down to wattage vs combined speaker cone area. I know there's some math that someone can apply here and help me out. Thanks!
