So I've been struggling with the boomy low end on my GK MB212 combo. Great amp, light powerful enough for an out door gig (sounds perfect outside), over-all great tone, but I've been playing a lot of smaller theater gigs and the low end is just too much. I bought an FDeck HPF pedal which allows me to roll off the lows at anywhere from 35hz to 140 hz and I'm finding that inside I have the lows rolled off at 12 db/octave from about 130Hz down. This did the trick, but its Christmas and daddy needed a new toy so I pulled the trigger on an Electro Voice ELX112p cabinet (with Mrs gmarcus's blessing) http://www.musiciansfriend.com/pro-audio/electro-voice-elx112p-active-12-loudspeaker I played in a band that used the 115 version as mains and my bass sounded great. These are only 37 lbs ( according to the EV manual) and pretty compact, plus they are kind of like a powered AK Thunder child (not as much bass, but I don't need that much deep bass). It's supposed to show up on Thursday. I'll let you know how it sounds and I might have an MB212 for sale......or a lightly used ELX112p if it doesn't work out. advertised specs: Freq. Response (-3dB): 60Hz-18kHz Freq. Response (-10dB): 50Hz-20kHz Max. Measured SPL: 132dB Coverage (Horiz. x Vert.): 90° x 50° Power Handling: 1000W LF Transducer: (1) EVS-12K, 305mm (12") Woofer HF Transducer: DH-1K, 39mm (1.5") Titanium Diaphragm Compression Driver Crossover Frequency: 1.7kHz Connectors: (2) XLR/TRS Combo Jacks, (1) Stereo RCA, (1) XLR Link Output Enclosure Material: 9-ply, 15mm Plywood, Internally Braced, with Textured Paint I get all of my tone from my pedal board (VTbass, Pork Loin HPF + some fuzz) so I really just need an accurate monitor. This particular model has 3 vents on the front so I'm keeping my fingers crossed that it doesn't chuff. Its a plywood box so I can put some big rubber feet on the bottom and on the monitor position side.
