Power and Value with N-Series

NVX's entry-level subwoofer is anything but "entry-level." NVX has engineered the NSW122 with exceptional features, such as a polypropylene cone, Nomex single spider and a high excursion rubber surround. This all adds up to a sub that moves more air for awesome, responsive and deep bass. The 2" dual 4-ohm KSV voice coil gives you a wide array of Ohm load wiring options for different applications. With an RMS Power Range of 200-350 watts, the NSW122 requires less power to operate efficiently without losing bass quality.

Continuing with the excellent engineering is a stamped steel basket that provides exceptional rigidity and the spring-loaded, chrome plated push terminals ensure a strong and dependable speaker wire connection. NVX's mission was to create an exceptional subwoofer at an entry-level price without sacrificing the quality and sound that the consumer deserves. They have succeeded!

Additional Information:

*CEA-2031 Compliant: All CEA-2031 compliant loudspeakers adopt the same testing and measurement methods so comparing them side by side is easy. Loudspeakers include car speakers and subwoofers. The Consumer Electronics Association created new testing and measurement methods for mobile loudspeaker systems that define test procedures for rating the performance and physical size of speakers. This is important because you can now compare different speakers on the same playing field. Any manufacturers who adopt the CEA-2031 logo product mark can be compared evenly to other speaker manufacturers with the same mark.

Not Entry Level Subs!!

My sister got the 2 for $99 special for me when Sonic had that deal. Great subs with great features. They are constructed really good. I have them in a sealed box with 1.5 cubes each and they hit nice! They hit the lows and keep up with all types of music. These are not meant for SPL, but they do play clean. These are far from entry level subs. Best subs in their class. Get them before Sonic raises the price on them.

Greatest value for subwoofers around

These subs are comparable to kicker comp vr's at 1/3 of the price and use less wattage. If anyone is looking for unmatched quality sound on a budget then these are the subs for you. I'm only pushing them with 250 watts each and they are slamming. If you're looking to shake houses then get four of these with a 4 channel amp that pushes about 250-300 watts per channel rms and you will be the king of the block. I've had kicker, Power acoustik, JLaudio and others and letter me tell you these entry level subs are great quality for the price.
