My apologies if this has been covered before but I couldn't find anything on it. Scenario: I currently have two speaker cabinets, one with a 15" speaker and the other with 2 10" speakers. I'm thinking of having a better enclosure made for the 15", however a friend of mine will sell me his SWR 2X10 cab (speakers included) for less $$$ than it will cost to have the new cab built. Question: Will having the 1x15 and 2x10 setup give me a broader frequency range than the two 2x10s? In other words, punch from the 10s plus deeper bass tones from the 15? Or will 4 10" speakers do the job as well? Other facts: My amp setup is a preamp and a 2 channel power amp with 200 watts per channel. I play both 4 string and 5 string basses. I play fingerstyle, with a pick, and also slap. I really like the punch, clarity and definition from the 10" speakers. Thanks for any advice.
