Big bass in a compact package

Back in the day, particularly when it comes to audio systems, bigger was always better. Just a few years ago we saw amplifiers the size of cars and chromed-out subs that would rival the presence of a doubledecker bus! Luckily though, things have moved on somewhat and nowadays practicality, sound quality and usability are king. It looks like the development boffins at Kenwood have taken note too and next released their latest active woofer, the KSC-SW11. Here’s what you need to know…

The first thing you’ll think as you open the box is where’s the rest of it? It really is that small. It’s a huge testament to the engineering sorcery at Kenwood that they have managed to cram an 8.25×5.2-inch sub plus an amplifier into a chassis just 11-inches long and 7.5-inches wide. What with the fact it’s less than 3-inches high too, it makes this one perfect for stashing away under a seat, behind the dash or in a footwell. The art of stealth!

Even though you’ll probably be hiding the unit away in the nearest available nook or fanny (cranny Midge, cranny – Jules), you’ll still be able to tweak your sound without the need to pull it all out or perform backbreaking feats of contortion. The wired remote is designed to be installed upfront and, along with a handy volume control, allows fine-tuning of the phase and a lowpass filter. Most importantly though, when the power is on, this thing glows blue. Yes, that’s right, blue. Lovely, lovely blue. Technology eh? We likey!
