Sorry in advance for a possibly stupid question(s): I just picked up an Eden D-410XLT, and I'm powering it with an Ampeg SVT 4-PRO (mono bridged 1200 watts into 4 ohm 750 watt cab) My question is.....as far as turning up volume on the amp, where do stop before you start pushing the cabinet to a danger point? 12 o'clock? How do you know where your limit is? I played a gig this weekend and had it turned up to 10-11 o' clock - good sound, but I was scared to go any higher. Also, I have both passive preamp and active preamp basses - on the active with the -15dB pad engaged there was a pretty dramtic rolloff in sound (it was obviously working ). What sort of problems am I opening up if I don't use the pad with the active? This is the first time I've had a rig with headroom, and I'm deathly afraid of ruining this nice cab. Thanks for your help.
