The most powerful subwoofer that Helix has ever made. This deep bass giant is able to convert up to 3000 watts of amp power into amazing sound, even at the lowest frequencies without any compression. It is no wonder, because its extremely long-excursion driver system can move incredible volumes of air. It is exactly the same as for cars: there’s absolutely nothing that can replace cubic capacity.
Yet for all this sound power, the SPXL 12 is also the master of exceptionally fine dynamics, able to delight the most audiophile listener. This outstanding talent finds its ideal sparring partner in the Helix SPXL 1000, which rises to the challenge of providing the power needed to drive the system with ease.
Features
- Concave PP dustcap with embossed HELIX logo
- Extremely stable Kevlar / paper sandwich cone
- Machined aluminium mounting ring for fixing the rubber surround
- Huge 100 mm flat wire voice coil with incredible 57.5 mm winding height on black aluminium former
- Rugged butyl magnet cover with HELIX lettering for perfect magnet protection
- Long-excursion rubber surround with double stitching for highest mechanical rating
- Torsion-free aluminum diecast basket with diamond cut
- Double nomex spider avoids non-linearities of the cone suspension
- Massive triple magnet system 3 x 3 x 100 oz (8,505 g) with chrome-plated machined pole plates
- Magnet size: Ø 220 x 75 mm
