Running high power amplifiers as Bi Amp rigs eliminates these problems 1001RB Series Tech Talk Electronic Crossover Bi Amp systems allow the crossover to be electronic and therefore have much higher quality than passive cross overs A crossover separates the sound into two parts high and low frequency The highs are sent to the horn or high frequency cabinet and the lows are sent to the woofer In an ideal system adding the highs and the lows back together would recover the original signal Most passive Bass systems have very poor crossovers resulting in severe signal corruption When these signals are added back together as in your ear they have very little in common with the original signal The 1001RB Series uses a Constant Voltage crossover which results in very little signal corruption In fact when the high and low signals are added back together the result is extremely close to the original This makes a two way system sound more seamless and less artificial We have also included a Tweeter Hi Cut switch in the crossover which rolls the tweeter off above 10kHz giving it a less glassy more cone like sound Equalization The sound you want is in your head but you just can t get it You think it s you your bass or maybe your amp Yes your amp Standard tone controls and graphic equalizers don t get it Sure they give you plenty of variation but they don t provide what the instrument really needs The
