Size: 18-Inch Single Subwoofer
Sounds good, loud, and built well. Great old school passive sub for live sound. It’s heavy but no getting around that with an 18” speaker and wood cab.

Size: 18-Inch Single Subwoofer

Hit very hard when ran with the right amp and crossover. I use a BBE sonic maximizer with crossover and a Behringer inuke 3000. I have played weddings, restaurants, bars, and clubs with these they are very decent speakers, and they take up no space at all.(smaller than a speaker stand, and way more stable) ... show more
