Tarantula Series

T4 woofers require Full Throttle engineering for maximum SPL and power handling.

These SPL machines are made to take the abuse of "Class D" amplification. You see "Class D" amplifiers will over heat a voice coil 2 to 3 times faster than a standard amplifier.

We use custom mixed glues along with 18 gauge voice coil windings to handle that extra heat and abuse.
