I have a GK 400RB 200 watt amp and a chance to buy two cabs each having two 10 inch 16 ohm Legend speakers. That would amount to two 8 ohm cabinets. Are 4 16ohm 10 inchers a good setup? Blues and funk are my predominate style and would it be loud enough for most clubs? Is there a drawback to the 16 ohm speakers? Thanks!
