Thanks for the heads up on the crossovers! I have not heard of that. I feel sure my 20s are the older ones. I got them in about '85 or early '86. I just had the surrounds replaced on all the bass drivers by a local guy. He supposedly bought Mac correct material. They still sound good, so it's all good!
I auditioned the new 28s and was not all that impressed, either. The shop owner stated the room they were in is terrible, acoustically and was pretty high on the speakers. He claims they
far surpass the old 20s. He is over two hours from my house and told me he would bring them up one Saturday or early evening to set them up for a home audition if I was really serious about buying them. Can't beat that! I thought the highs sounded really sweet, but the bass stunk. It could have been the room, but I don't know! I suggested that he move them or do some treatments so folks that were interested in that high priced of a speaker system might get a better idea what they could do.
I was looking pretty hard for another 352 and run them both in mono if I bought the 30s or 28s as they will handle a lot more power than the 20s. I got a good deal on my 352 from a dealer that was going OB. I really love that amp!
I had a chance to buy a set of the 30s at about 40-45% off from a dealer but really have a hard time even at that discount spending that much on a set of speakers I have never heard. It's not like I have two money trees in the back yard! One, maybe, but not two. Plus it's winter, so the one I have isn't putting out much fruit. Come on tax refund!
