I'm currently trying to over-nerd my live performance rig. And so I turn to you, TalkBass Forums, for wisdom and advice. The signal chain looks like this: Bass feeds into a MOTU Microbook for preprocessing with Ableton Live, then into my GK MB150E-III. That acts both as a preamp and as the stage that powers its internal 12" speaker. From here, I take a line out of the FX send (hence, post-EQ and post-chorus effect when it is on) and send it to the speakers. And Here My Ambiguities Begin: I have an Ashdown 4x10, a Peavey 4x10, and a ridiculous club subwoofer. Ampwise, I have a Behringer iNUKE 1000 and a Behringer BX4500H. Options I currently have to connect this gear: A) iNUKE in mono mode with the crossover activated, connected to the Ashdown 4x10 on the full-range output, and the sub on the <100Hz output; BX4500H with the FX send from the GK hitting the BX's FX return (to bypass the preamp stage) powering the Peavey 4x10. Schematic of Setup A B) iNUKE in mono mode set to full range, pushing both 4x10s, and the BX4500H being fed into its passive input, then using its EQ to mimic a crossover (bass boosted, frequencies above "bass" cut as much as I can) powering the subwoofer. Schematic of Setup B The iNUKE in mono mode is good for 300W per speaker. The BX4500H at 8 ohms is also good for about 300W. If I put the iNUKE in bridge mode, it'll do a full 1000W, but I then have to build a special Y cable to make the 4-pole Speakon output connect properly, complicated further by the fact that the sub has a weird 3-blade locking NEMA connector. Anyway. What do y'all think will sound the best, and thump the most?
