hi im thinkin of buyin a decent rig for playin in a band oer the summer. i think i know what im getting: the head will be a behringer 3000t ultrabass 300w at 4ohms and then for cabs im going to get ashdown mag cabs because i dont have a whole lot of money to spend. but this is where i need advice should i get a mag 4x10 AND a mag 1x15 or would the 4x10 be enough on its own to compete with a guitarist with a 4x12 half stack, another guitarist not sure what amp they have and a loud drummer. the 4x10 is rated at 8ohms so i will only get the half amount of power or whatever but would that amount be enough for me to compete with the above mentioned or will i have to get the 1x15 also at 8oms and use all 300w of power. please dont say get the 1x15 unless i really need it coz like i said i dont have that much money to spend and id rather not get the 1x15 at this point unless it is neccessary. i will get one though if we get good and start gigging. so what do you think, both cabs or just the 4x10?
