A sealed-back 100W RMS 4"" woofer from PowerAcoustic ideal for autosound applications.
I bought (2) of these speakers because of the 120w RMS rating to use in my shop as part of my sound system test gear capabilities since I do custom design & manufacture musical instrument power amplifiers and I am an authorized service center for many name brands of gear. The RMS stated is simply not real world RMS, these speakers blew at about 60 watts "RMS" running at half their rated power on my 3 way crossover systems. The sealed back is ok for automotive door mounted low wattage systems only... these speakers are not for medium to hi-powered quality sound systems!
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
