While McIntosh is more well-known for superb components, the XR230 leans on the company's legacy and nearly 20 years of loudspeaker design. There's a tiny cosmetic blemish in one of the tweeter faceplates, and a bit of sunbleaching, but sonically, these are in top working order.

- LINER NOTES
The XR 230 is a three-way system with excellent dispersion, using a high power handling woofer, a carefully matched midrange driver and a one-inch tweeter. A complex and extensive crossover accurately blends the drivers together. Each driver is designed to work best in its frequency range. At low frequencies a woofer with large cone area and long linear excursion is required. The cone must remain rigid and not "break up" into independent modes of vibration. The mass of the moving parts must be as low as possible, yet constructed in a way that will not allow these independent vibration modes to appear. The magnetic gap must supply the required force at 20Hz, the lowest operating frequency. The upper woofer's limiting frequency is where the woofer's radiation becomes directional. Above the woofer's operating range, the dividing network transfers the driving power from the amplifier to the 5-inch midrange. The smaller diameter and lower moving mass allow this driver to move effectively without breakup. Above the midrange the crossover network again transfers the energy; this time to the 1-inch dome tweeter. Its very small relative diameter and extremely small moving mass permits it to efficiently radiate high frequencies up to 20,000Hz.
