DB2.1s 2/1 Channel Bridgeable Stereo 12v Power Amplifier 540w Verified RMS Power Output

World RRP: £149.99


Product code: DB2.1s

The "ordinary" DB2.1 has been evolved into a great sounding and reliable little amplifier but there exists a gap between it and the monsterous DB2.2 which this fantastic new product fills squarely. With 50% more power than the standard DB2.1 the DB2.1s has enough grunt to run big component speakers with ease or even a decent sized subwoofer with authority. The DB2.1s still maintains a compact footprint, relative lightweight and excellent efficiency but the output is much more beefy than its smaller brother. Upgrades that have taken time to bring to the earlier models are applied right away to this "s" model - including professional type cable connection blocks, rounded feet, cushioned backplate and higher density casting.
