Accugroove was born out of a search for a fuller and more sonically complete bass speaker. It's a "One Cabinet Does All" approach. No more mixing & matching cabinets to get the sound you need, Accugroove has already done it for you & then they put it into one compact cabinet. The end result is Accugroove's exclusive Four Way cabinet design with Sub-Woofer, Mid-Woofer, Mid-Range & Tweeters. Each driver is then enclosed in it's own specially tuned "cabinet within a cabinet." This way each driver remains true to it's own unique sonic signature.
