The crossover characteristics of the Beolab 3's as discussed above did remind me of a earlier thread about the presumed lack of midrange of the Beolab 9's. Does anyone know if the 9's are designed with comparable crossover frequencies?
Being a three driver speaker the crossover freq's in the 9's are as follows:
The frequency range of the 10 inch woofer is 30 to 180 Hz, being exactly 2,5 octaves. The 5 inch midrange operates from 180 Hz to 2 kHz, which is approx. 3,5 octaves and finally 3/4 inch tweeter takes over from 2kHz all the way up to 20kHz, which is if I' am all calculating correctly 3,3 octaves.
Thinking of the presumed lack of midrange (I have experienced more or less the same) it just reminds me of the following paragraph in Beocentral's productdescription of the BL9's:
Quote "The BeoLab 9 used 3 drive units, described as a 10” woofer, a 5” midrange and a 0.75” dome tweeter. This made for a nominally 3-way loudspeaker, though given the sizes of the drive units and their crossover points the effect was more akin to a small 2-way loudspeaker working in conjunction with a well-matched subwoofer."
