i would like to buy a head, and just make my own bass cabinet. i was wondering wether this is to supremly hard. i'm skilled and can build anything so that is no problem. however i was wondering wether i should try to come up with my own design or copy a classic like a bassman. i was also wondering if i do wether it should be open back or closed (lower frequency with closed right?). i wanted 2 15" in it and was also wondering wether i should buy any peticular brand of speaker, or could i basically get any quality speakers. any hints or suggestions would be much appreciated. thnx.

also - would it matter too much if i bought a mesa boogie head but copied a bassman cabinet?
