i have this nice empty 75liter internal volume 210 cab with tweeter,(not empty actually but no great speakers in there...), tuned to 60hz. which speakers would you throw in for replacement? eminence:: alpha, beta, deltalite, delta 10a. the 1st tow cost half of what the latter two cost. how about the betas ie.? winisd simulation looks normal. i would be happy if the result was about what you can get from mid price stock cabs. say the nemesis 210.
