 So you're extending the mids down to the 80hz point and then rolling off to the subs for a 3 way instead of a 4way?
Can you hear the difference if you crossover above 3500hz or well below it, in human voices? I guess if you match the dispersion, phase and have a flatish FR, you shouldn't be able to tell the difference, right? Life would be easier if I could live with a 2way (3way when the sub is taken into account) |
It is only with the center channel that I let the midbass drivers extend down to 80hz because it has 2 of them therefore it has the volume displacement to handle it.So yes when combined with the sub it would be a 3 way.
My main speakers have only 1 midbass driver so I cross it over to an 8" woofer at 300hz then the 8" passes off to a 10'' woofer at 50hz to make it a 4way.
Generally it would not be advisable to crossover a 6.5" midbass to a 1" dome tweeter above 2500hz because the off axis response will be poor due to the narrowing dispersion pattern of the cone as frequency rises or in other words it becomes directional or beamy.And yes if the system has poor off axis response it will be audible.
A smaller diameter cone like a 4" or midrange dome could probably be successfully crossed over at 3600hz.
Most high performance 2way speakers on the market have crossovers that are well within the human voice range 1.8-2.5k so it is not a problem as long as it is done correctly.It depends on the actual drivers being used.
