CEA Compliant Legitimate Power Ratings
Description:
Rockville W8T4-S4 8" Subwoofers feature the thinnest mounting depths available making them the best shallow-mount driver's suitable for the most intricate bass installations. Deep bass that's made to fit where standard-sized subwoofers can’t. What else can you ask for?
The
Rockville W8T4-S4 subwoofers feature a 4-Ohm single voice
coil. These subwoofers are engineered to deliver
serious low frequency response where space is limited. Whether installed
behind the seat in a compact car, pick-up truck or in a motorcycle's saddlebags,
make no mistake Rockville T4™ subs will rock you!
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 W8T4-S4 is CEA-2031
compliant and rated with an amazing 1000 watts peak and 250 watts 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.
If you are not happy with these, we will call tag them and take them back within 30 days of when you receive them for a full refund. On top of that you get a 1 year exchange warranty for any defects.
If you want the best value for a shallow mount car subwoofer, and you want a great quality product that sounds great, and you also want hassle free return policies, then we highly recommend these Rockville T4 subs.

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.
