Real one for two systems with powerfull out put !!
The SP156AP is dual power full-range 300WX2 amplified enclosure with one 15” SK15300H low frequency drivers vented.
Designed for portable systems,the active stereo mode required from AV music and active parallel mode for distributed installation design.
The one power outputs dedicated to powering internal 15" LF driver with HF compression driver and the other one full range power outputs used to drive the Passive SP152H speaker or equivalent systems.

  • 2-Way full-range dual Amp active system.
  • High output and with very low THD and broadest bandwidth.
  • The one 2” SK60D exit compression drivers on a “SABS2” horn.
  • An internal crossover frequency is 2 KHz 12dB/Octave.
  • The STK "CIRCUIT PRO"protect to the HF driver from accidental overload.
  • Ultra tough, the scratch proof warnex texture coated.
  • Impact-resistant perforated Metal grill with weather proof powder coated.
  • 35mm pole mount receptacle on the bottom.
  • With or without flying hardware options for eyebolt joint.
