hello all, first time poster, long time reader. I've been in the market for a new bass rig (my peavey 210tx combo ain't cutting it anymore, ddt limiter is virtually on all the time at rehearsal volume). I have found two great deals in my area as an upgrade. 1) svt-4pro w/ 410hlf 2)svt-4pro w/ svt 810e The svt 4pro is totally capable of smoking both of these cabs in an instant if not operated properly. From what i have read, the low frequencies tend to contribute to this nearly as much as getting overzealous with the volume knob. Which brings us to my question. Could/should I run a sub off the amp as well while biamped? anyone have any input on running the svt-4pro biamped, since it has two power amps, with one side going to either the 410hlf or svt810, and the other side going to a passive subwoofer, then using the crossover to send anything below 60hz to the sub; Hopefully thereby keeping the sound of the midrange a little bit tighter and possibly limiting the risks of burning out the drivers in the 410 or 810. I am buying one of these two setups this week, I was more or less curious if anyone had considered pairing a subwoofer with their rig on stage. I play a six string that is tuned stupid low for drop c (yeah, you guessed it, metal band). Low to high it is tuned GCGCFBb. I ordered a set of fat ass Kalium strings that keeps everything from getting floppy at such low frequencies on a 35" scale. Let me know your thoughts or if you have tried something similar. Thankyou!
