Fraktal

Hi everybody! After reading reviews, opinions and comments everywhere about Markbass gear I decided to buy a Markbass combo. My previous rig was nice regarding power and sound, but a nightmare to carry: Trace Elliot GP12SMX preamp, 2 rack power amps for crossover'ed biamplification and a 1000w Warwick Terminator cabinet... Including flightcases, I estimate the total weight around 70Kg+ for the cabinet and 45Kg+ for the rack mounted units... insane! I need lots of decibels cos the drummer of my band is incredibly loud, the loudest one I have seen in my whole career as a professional bassist (16 years) and of course, everybody has to adapt their volume to his, since reducing an acoustic drum volume will inevitably result in compromised tone, and he is unwilling. Now the problem is to choose between the MINI CMD 151P(1x15"), the MINI CMD 121P(1x12") and the 102CMDP(2x10"). they all seem to have the same wattage, so I assume the difference in sound will come mostly from speakers and enclosure. Unfortunately, I live VERY far away from any decent dealer with a decent stock to have a chance to try before I buy, so I will have to buy one of them blindly I personally prefer 15inchers but this opinion might be based on the fact I have never tried a 10inchers amp that satisfied my lowB string sound demands. The 12incher combo looks to be the smallest and lightest one of them(and also the cheapest), but I suppose it wont handle low frequencies at max power as good as the 15incher??? Also, people seem positively surprised about the low frequencies coming out of the 10incher combo(from what I have read). So, here is where you guys can help me a bit. Since all I have are speculations, I would sincerely appreciate opinions based on real life trying of those 3 combos and, if possible, direct comparisons between them. Surely a few of you have been in this same dilema before than me! Thanks a lot for your time
