I bought 4 of the LX-4s when Radio Shack closed them out. This model paired the Lineaum tweeter with a 4" kevlar woofer. I then performed the Dick Olsher mods to the crossovers. I was able to feed them with over 100 watts and they not only sounded good, but filled a small room surprisingly well. I still have them, but haven't hooked them up in years.
