Hello! I'm a bassist that just started go get some small outdoor gigs. My medium size rig is a Markbass traveler 102P and a TC Electronic BQ250 (I got a Genz Benz ShuttleMax 12.0 and a 1x15 cab that I designed and built for larger venues). The thing is that lastly some venues are in large open malls and I need to carry my rig for a mile from my car to the gig place (yeah, yeah, I know, it's not even a quarter of mile, but you know what I mean) and since we're not a loud band (we play jazz and instrumental rock and surf like The Ventures / Shadows) my rig is almost iddle. I mean, nor the bass or the cab volume arr even at 40% of the volume, so I decided to pull the trigger on a small but good sounding combo or cabinet. My first options were a Markbass 801, Markbass CMD 101, Trace Elloit Elf 1x10, Genz Benz 10T but I could not found them in good shape at a great price, so meanwhile I hunt one of them I thought that maybe it was time to put hands on and build my next cab. I'm considering to use one of these drivers: Faital Pro 10FH520 Neodymium 8 Ohm 600W RMS Freq 60 to 4,000Hz Sensivity 97dB Fs 60Hz Xmax 7.25mm Weight 9.55lbs $267 B&C 10NW64 Neodymium 8 Ohm 300W RMS Freq 50 to 2,500Hz Sensivity 96dB Fs 50Hz Xmax 8mm Weight 7.7lbs $165 Eminence Kappalite 3010LF (Out from catalog, but still able to get one) Neodymium 8 Ohm 450W RMS Freq 42 to 1,600Hz Sensivity 92.7dB Fs 39Hz Xmax 8.5mm Weight 7.6lbs $185 Roughly I see the Faital Pro more loud but less low end. Eminence the opposite and the B&C in the middle. My newbie logic says Eminence because althought it's just 92.7dB it would handle better low frequencies, but I doubt that the Markbass, Trace Elliot and GenzBenz 1x10 stuff has these numbers. The thing is that I'm lost on how bad is getting a driver that goes from 50 to 2,500Hz and not from 40Hz (as far as I know, 4th string E is 40Hz), I mean, are all drivers used in commercial cabinets going from 40Hz? Trying to buy stuff by numbers is making me think a lot on the tradeoffs but without a real life clue about how good or bad are these numbers compared with the high runners from the good commertial brands. Any inputs regarding the driver chosing are more than welcome. It would be also very helpful to get crossover and tweeter recommendations. Here's a pic from my first and so far only gig with this band so you can picture my situation and needs. Thanks!
