Our take on the Jensen DUBa1450

by Bob Bihlmayer
Jensen

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Jensen + DUB

Since 1925, Jensen has been a pioneer in home and car electronics, developing landmark products such as the first high-efficiency loudspeaker and the first aftermarket car speaker.  Now Jensen has partnered with DUB® magazine, the leading publication in the urban automotive lifestyle market, to introduce DUB Edition speakers and amplifiers, featuring DUB-designed cosmetics and co-designed components.

Boom for your zoom

The DUB Series DUBa1450 mono subwoofer amplifier will send up to 400 watts RMS to your subs, while its variable low-pass and subsonic filters and bass boost let you zoom in on the sound you want.  This Class AB amp uses a MOSFET power supply and high-current output transistors to deliver strong, reliable power, and it features full short-circuit, DC offset, and thermal protection, so the music won't stop until you want it to. And why would you want it to? You've got DUB on the case.
