Helix IK S12-SVC2 (1x2Ohm)
The Helix IK S12 is a high-quality low-profile subwoofer that operates in a small enclosure and comes with a protective grille.
The installation depth of this element is only 95.5 mm, so it can be installed in a very shallow housing.
Helix's IK series subwoofers work in small enclosures. Both reflex enclosures and sealed enclosures. Reasonably priced drivers available with 2×2 Ohm and 1x2 Ohm voice coils. The IK series drivers offer very good sound quality from a small enclosure.
