A:Answer Hi,
Thank you for your question. We consider this speaker a woofer not a sub-woofer. It's intended to be use along side other 4" and 6" distributed audio speakers to provide added mid-bass sounds. It does require its own amplifier. I recommend using our Sonamp DSP 2-150 MKII amplifier to power the speaker. I hope you found this information helpful. If you have additional questions, please call our California-based support team at 949-492-7777 and ask for Tech support. We are available Monday - Friday, 8 AM to 5 PM PST.
