best bang for the buck!!!

I own this subwoofer, i love the design and sound it makes. The best thing is it has alot of punch and deep bass. I use mine for live music at small gigs and works great, i would say works cool and very dependable since my gigs go 4 to 5 hours long. i have powered tops so i use the outputs with crossover built in and never worry about blowing a speaker or distortion, over all grate stuff and compared to all the high end stuff it hangs with the big boys, i know because i do small halls and all kinds of events so buy with confidence.
