A sealed-back 100W RMS 4"" woofer from PowerAcoustic ideal for autosound applications.
Waterproof and the grill allows clearance with the window crank. these speakers work well in the Vanagon and sound great as well. I used them with a 3 way crossover as the midrange.
the mid bass / mid range is a must have for your home stereo or car with the clearest sound quality at high volumes i run them on a home stereo with a Harmon kardon amp. the xps-104 are in my floor standing cerwin vega's and they sound awesome a 5 star all day long
I have always had the best of service and response from MCM. Highly recommended!
