This is an original midrange driver for the AR-5 and AR-LST/2 speakers in excellent cosmetic and acoustic condition. We generally retain these for repair orders. However, we promised to list some of our extensive inventory. Initially, we have 8 available. Inspected and tested with test equipment and a music source. This should give you many years of great service. You should definitlely have a spare for your AR-LST/2 as the complex crossover in not easily adapatable to substitutions. Acceptable replacements for the vintage AR speakers becomes more difficult to find each year. Although this looks the same as the midrange of the AR-3a and AR-LST, do not confuse it with this, they are not the same. The impedance is different. This will not work correctly in the AR-3a nor AR-LST application. Please browse our entire store. We are continually adding new items for the Acoustic Research fan. The free listing tool.
