I have made the decision to get rid of the Hartke Transporter 410, and buy another 210 to use with my current Avatar B210. 410s are plenty for the gigs I play, and I can use just one 210 at practice/small gigs. I have been looking at getting the Avatar 210 Pro or either the Dr. Bass 210(Rx.) Here are some of the issues (or non issues) involved: Price/shipping-close enough not to matter. Weight-non issue. As long as it sounds good I don't mind carrying it. Tuning-Dr. Bass cabs are tuned lower (will I be able to notice a difference between 59hz and 45hz?) Speakers-From what I read here, Dr. Bass uses Deltas, this Avatar uses Kappa Pros. Tweeter-non issue. I rarely use one. Wattage handling-my power amp is capable of 425 watts per side (but I never get to use that many.) Rat fur vs. composite covering-still pondering that one. What do you think?
