Traditionally there is the X-Curve for "large rooms". From what I've read it becomes much less useful in typical small HT rooms.Hi everyone,
Trying to do a similar frequency distribution between drivers as in a full size cinema and have been toying with the idea of a 12" prosound driver for 80-500hz and use a mid size full range above. In a true cinema, above 12k is usually rolled of a little, sometimes deliberately but usually due to large diaphragm horns not being able to go so high.
The 12" drivers I have are around 96db efficient, so something up around 93 would be good. I was looking at fostex Fe126en or ff165wk as above 500hz their efficiency is reasonable. Obviously they will go in small sealed chambers and crossover will be passive, probably first order. I don't listen at huge volumes all day and movies are quite dynamic so I figure average power should be lowish. Power will be from a 130w/channel high end Sony amp.
Thanks for any ideas/experiences you can share
I guess I'm a little confused about what you're really asking. Are you planning on building a 2-way or 3-way? If you're thinking of an xover at 500hz, you're definitely going to need a 3 way design.
Pro-sound drivers are very often a mixed blessing. They are generally efficient but lack extension and excursion.
