"Patent Number 4,267,205:
Stereo Speaker Systems for Creating Stereo Images,
for Drivers Arranged in a Long Column
Patent Number 3,705,501:
The Use of Equalization to Compensate for
Natural Frequency Roll off of a Loudspeaker System"
With these patents does that mean you're not allowed to sell line arrays or use active EQ to boost the low end of a speaker? That's how I read them.
EDIT: I've searched and searched on many patent sites and I can't find either patent anywhere. Both numbers bring up patents that are old and are in no way affiliated with loudspeakers.
