This is for one new, AR Replacement Midrange driver for the AR-3a and AR-LST speakers. This is the rear terminal configuration. Offered as a replacement after AR stopped making the original. Manufactured by the same company that made many late production AR woofers. This is the only one we have. As originals are becoming almost impossible to find, putting this away for a long term spare might be wise. This is the rear terminal version. If your speakers are front wired, you may add your own wires, or wire them internally or bring wires from the terminals up through a hole drilled near the front panel terminals. Includes the original gasket seal. Unfortunately, care was not taken to locate the rear terminals in the same locations as the originals. A 3/8 drill might be necessary to drill new clearance holes to make the adjustments. The midrange mounting holes are in the same locations as the originals. We are continuing to add new items.
