Helix K 12W

kr1,490.00 kr1,117.50

Do-it-yourselfers, here′s your chance to create your personal sub that perfectly fits into your car! From the technical point of view the two drivers K 10W and K12W are absolutely identical with the subwoofers that are installed in the K series enclosure subs. Just have a look at the Thiele/Small parameters and you will easily notice that those are designed for compact vented cabinets yet leaving plenty of ″headroom″ for designing your own preferred sound characteristic. If you prefer to play it safe, just choose the same net volume and port tuning frequency like our enclosure subs K 10E and K 12E for outstanding bass performance. So what are you waiting for? Start your ″tailor-made subwoofer project″ right now!
