I purchased this to add some SPL to my HT it is in addition to 2 Klipsch 15's and another Sundown 15. This 18 did exactly what I got it for...added much needed SPL to the room. I built an enclosure 20% Larger than Sundown's suggested 7 FT3 and tuned it to 36hz so it peaks around 40hz but does really well down to 20. It is powered by a Dayton SPA 1000 and at the 1000+ dynamic power is just insane. With music it fills in those low bass notes and hard hitting kick drums in a way those Klipsch 15's cant. Well worth the time, money, and effort. ... show more
