Description of Rockville Subs:

CEA Compliant Legitimate Power Ratings!

Peak Power = Amount of power the sub can handle for a burst during the loudest point during a song. This number is not as important as the RMS power. This subwoofer has 1,800 watts peak which is a lot of power for a small 12" subwoofer.

Program RMS Power = The Program RMS power the way most middle of the road brands on the market rate their products. This sub can handle 900 watts program power. So for example a 900 watt Program RMS Hifonics amplifier will work perfectly with one of these.

CEA Rated Power = This is an official tested rating by a specific industry standard. This is the way the top brands in the industry such as Kicker, Rockford, etc rate their items. This subwoofer is 450 watts RMS CEA rated. This rating is measured at a very specific distortion level. You can feel confident matching this with a high end amplifier from Kicker, or Rockford, or any other high end brand that uses CEA compliant ratings. 

We supply all 3 ratings so that you can compare prices of our product to any brand on the market and also so you can confidently match this subwoofer to amplifiers from many other brands.


Utilizing a sophisticated “High-BL” motor structure together with a large-diameter, progressive-roll spider provides increased linearity and superior overall sound quality. A vented core magnet motor structure with extra thick back & top plates allows for full voice-coil extended peak-to-peak excursion, creating ultra deep bass response. Engineered with a special aluminum alloy high-temperature voice coil winding around the high-mass vented pole piece, helps to keep the woofers cool even when your music gets “hot”!

The Rockville W12K7-D4 is CEA-2031 compliant and rated with an amazing 1800 watts peak and 450 watts CEA RMS. That means you are getting 100% accurate RMS power ratings. These days lots of brands have competitions over how many thousands of watts they can write on the box of their items. The problem is you do not know what you are getting from them. It is easy to print a box that says 2,000 watts Max. Our subwoofers are rated in the same way that other famous brands rate their products. We also feel our manufacturing engineers are the best. The sound quality on our Rockville subs are just amazing. Our engineers who design the subwoofers are all in in the USA and have over 30 years experience manufacturing car audio.

About Rockville Quality Control Procedures:

The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville monitors are backed with a full one year warranty, though it is unlikely that you will need to use it.
Description for Rockville Enclosure:

The RD12 dual sealed speaker box is made in the USA with Grade “A” ¾” MDF wood. This enclosure is made with precision cutting machinery by industry experts that have been making these enclosures in the USA for over 20 years. All Rockville enclosures come with a customized enhanced glue that is unmatched by any other manufacturer. That means that the carpet will stay in place and not rip or tear. The ¾” USA MDF is much stronger then any type of import wood.  This will keep your box performing at an optimal level by not flexing and distorting your woofers. Your woofers will thank you!  EVERY Rockville enclosure is not only glued at all joints but stapled as well. If that wasn’t enough we add a layer of silicon to every seam! This makes your Rockville enclosure rock even more!
