I did replace all the drivers in a Alon 5 with all alnico drivers from a Alon Circes. Carl at Alon /Nola said they would drop in and work fine and they did. I tried the old non alnico mid and tweeter from My Alon 5 in a friends Alon 2 and was NOT happy they look the same as the Alon 2 drivers but did not work very well the crossover I think is different but both are open baffle on the mid and tweeter. I found that the alnico woofer made the least difference in My upgrade. The alnico drivers are pricey and I would save My money on the woofers . I have two non alnico woofers from a Alon 5 I may sell but they need to be reconed . I also have two tweeters non alnico from My Alon 5 speakers I may let go. I did not think they worked well [ the tweeters and mids ] in a Alon 2 but who knows talk to Carl at Nola about crossover changes ? This is just one man's thoughts you may have better luck with a woofer change as I never did swap woofers [ non alnico ] from my Alon 5's in to the Alon 2's . I only swapped non alnico Alon 5 mid and tweeter drivers in to the Alon 2 . You can feel free to e mail Me with questions and I will try to answer them . Marc
