Hi everyone, i just started playing bass (after years of playing guitar), and i got on a Pawn shop an Acoustic 220 head working perfectly for $100. So all i need now is a cab. Since all cabs here in Mexico (just as all new music instruments) are a total rip-off, i decided to buy a speaker and make a custom cab. My question is, how many watts, and ohms should the speaker be? And what size do you recommend? Most of the shops here in mi city have only Eminence Delta, at fairly good price, (i noticed most of them were 8 ohms) i just need to know if i could use those with 8 ohms or if i should look for 4 ohms speakers, and how many watts do you recommend. The specs of this amp are: (You can see the full specs here http://acoustic.homeunix.net/twiki/bin/view/Acoustic/BassHead220) 160 Watts RMS @ 5 % THD into 2 ohms 125 Watts RMS @ 5 % THD into 4 ohms then on the other add it says (even though its the same model) 210 Watts RMS @ 5 % THD into 2 ohms 170 Watts RMS @ 5 % THD into 4 ohms What do you recommend? Thanks in advance.
