[QUOTE="Rich Frembes, post: 141922, member: 432"] Re: Danley SH96HO I'll have to come to Ivan's defense here. It's not necessarily always about a manufacturer hiding the "secret sauce". Sometimes there is no one number answer, and the messy, accurate answer can be off-putting to some. For instance, we have 2-way devices that have as much as an octave-and-a-half of overlap through crossover. The HF device might run down to, say, 500 Hz (OMG!) at some level of attenuation, whilst the LF device might run up to 2 kHz or more. What is the electrical crossover point? The acoustic crossover point is also just as tricky, as there are complex phase relationships between devices that come into play. The ACP might also have a wide range. The shoddy nature of the industry's one-number specification sheets lead people down the wrong path sometimes. It's best if you can eyeball actual on- and off-axis magnitude graphs plus a phase response graph. You'll see that interesting designs -- and I'll definitely count Danley among this bunch -- have really clever solutions that are hard to explain even in dumbed-down marketing terms. [/QUOTE]
