Hi, just looking for some advice from more experienced users of Altec small format drivers. I currently have 807 drivers with aluminum aftermarket diaphragms. I have a chance to get some 908-8A drivers locally for around $125 for the pair. They have no diaphragms in them and no back covers either. But they are in good shape and have the tangerines, etc. One thing that I was wanting to know is how much of an improvement would the 908s be over what I already have? I'm looking for more hi frequency than the 806/807 is giving me. Also, I noticed the one of the tangerines is black and the other is orange in the 908s. Not that it makes any difference but I wondered why they were different? I'm guessing they were made in different years. Please tell me what the advantages and disadvantages are making this swap. I realize the 908s will probably need to be crossed-over higher and will not have as good midrange as the 806/807 that I have now. But I think the 908s will have better upper-end treble and crispiness. Another scenario is that I just buy Altec Pascalite diaphragms and put them in my 806/807 drivers that I'm using now. Which way do I go with it all? I love the midrange the 806/807 can push out but the high-end treble is lacking somewhat. I do have them on an electronic adjustable crossover with CD Horn button (engaged to get any decent treble but it's not enough on the upper end). Thanks in advance!
