[QUOTE="Ivan Beaver, post: 141873, member: 30"] Re: Danley SH96HO That is a questions that has many different answers. The "obvious" ones are the electrical and the acoustical crossovers. Then you have to also consider the "physical lowpass" (or distortion reducer) that is built into almost all Danley products. It is a physical low pass filter that keeps the distortion (that ALL loudspeakers have) from getting into the horn after they leave the drivers. Then there is the fact that Danley does not use "normal" crossovers, so in many cases the different freq bands are actually overlapping, making the "crossover point" very wide. For example-in the active settings, the "electrical" crossover freq overlap by about an octave. But that does not mean the ACOUSTICAL crossovers do. Once you take into account the physical low pass of the cabinet-along with the natural lowpass of the inductance of the woofers, it takes that sort "alignment" to get a smooth phase response. And then you have other cases-such as the SH50, that actually has 3 crossover points on the HF driver alone. The first one is a lowpass around 15Khz that actually RAISES the HF level in the cabinet. Yes that is correct. But the "real question" is why does it matter? If I said it was 1500Hz, what would you do different than if I told you it was 800Hz? I'm not trying to be a jerk-or ass, but just pointing out that the "simple question" has a lot of complicated answers. [/QUOTE]
