Hifonics Zeus ZST-8D4

The HiFonics  ZEUS STREET ZST flat subwoofer series, which includes the Hifonics  ZEUS ZST-8D4 8" (20cm) subwoofer, has an easy-to-install  Flat construction. Thanks to their low installation depth of just 8 or 9 cm, these problem solvers can be installed anywhere where conventional subwoofers are simply too deep.

Conventionally constructed subwoofers have a deep cone, which keeps the membrane in good shape, but unfortunately has a negative impact on the installation depth. If you want to reduce the installation depth, such membranes are not an option; you have to use flatter versions. However, if these were built from conventional materials such as paper or plastic, flat subwoofers would not sound good. Therefore, the membranes of the  ZEUS STREET ZST  Series made of an extremely hard glass fiber/carbon composite material. This is the only way to ensure that the air is cleanly compressed at high bass excursions and that no distortion occurs  Also not common in this class are the drives with large magnets and 50 mm voice coils, which have an Xmax of up to  Allow 15 mm (+/-).

The 20 cm sub ZST8 can best exploit its potential in a closed enclosure volume of 10-15 liters, the ZST10 should be used from 15-25 liters. Both subwoofers also play very well in bass reflex tuning, which requires a little more volume, but then plays even more powerfully.
