I want to emulate a royal blood/death from above 1979 sound with my octave pedal. I built myself some cheap 8 inch subwoofers and plugged them into my bass and they sound f***ing amazing (also using my studio monitors for the high distorted freqs) since although they are not rated for it, with a bit of Ableton EQ I can get them to hit 27.5 Hz(they aren't the solution because I'm not sure they are as loud as a drum kit). I currently have a rumble (v3) 100 and was looking at purchasing the 200 since it has 1x15, but, I played it and it doesn't go much lower than the 100. Should I give up now? Does such an amp exist? Or should I save up for a 1x18 and a massive solid state beast? Or should I buy a subwoofer amp and build (or buy) an 18-inch car/PA sub?
