I currently have a 307W head powering cabs that can handle 1000W RMS and 600W RMS, they are in parallel. I'm pretty sure it's almost impossible to blow my speakers. I'm wondering whether my cabs would sound better if I weren't underpowering them so underpowerishly. I'm eventually going to buy a 1200W Kustom GrooveBass (which will only put out 800W at 4ohms, which means only 400W per cab) which will still underpower my cabs, but not as badly. Is it such a big deal that mycabs are being so underpowered? Would they sound better if their RMS rating was half of what they are now?
