[font=comic sans ms,cursive][font=Arial][font=Arial]Sorry- I don't have a good answer. If you connect the two cabs in parallel (daisy chained), the 4 ohm cab will receive 2/3 of the power, and the 8 ohm cab will receive 1/3 of the power. So, to use your word, it would be a mismatch.[/font][/font][/font]
[font=comic sans ms,cursive][font=Arial][font=Arial]The best way to use the two together would be to use a stereo power amp, use the amp's level controls to balance the two.[/font][/font][/font][/size]
