Turns out the guy who blew 1 of the Deltas in my 2x122 cabinet also damaged the other. I will replace the 2nd one soon. I'm looking for more cone area for volume with 500 watts. My 2x15 might be good but is too long for my car. 3015 in a TL606 is not full or loud enough Not so sure that a different 2x12 would be that much better but would be interested in opinions. Am thinking that a used 4x10 at maybe 55lbs would be something to consider. Any other thoughts? While I do have very powerful amps, I'm really liking this MB500. PS - I also have a Berg HT322 that is perfect but weighs 100 lbs with wheels and is a bit much to load by myself into the backseat of a 4 door sedan at 100 o'clock in the morning.
