Center channel speakers with horizontal lobing: The mid-frequency sound is different across the room, and dialog lacks clarity
The typical Center speaker is made of two woofers and one tweeter. The two woofers launch waves into the room, which at some frequencies will cancel each other out when you aren’t right in front of the speaker. That’s because when you are off-axis one woofer is further from you than the other, and its delayed waves will be out of phase with the those of the closer woofer. It’s like a rowing crew that is out of sync; it will lose the race. The biggest problems are around 2 to 3kHz, right where dialog presence lives. So you can’t understand what Batman is saying to Catwoman; very annoying!
Grimani Systems Solution:
Grimani Systems Solution: All of our speakers feature ultra-wide and constant horizontal dispersion. That means that the sound is virtually identical whether you are straight in front of the speaker or off-axis out to about 80 degrees on either side! The Conic Section Array waveguides we use for our midrange and high frequency drivers are the main component to achieving this astonishing and uniform coverage. We also carefully choose the crossover points and slopes to avoid lumps and bumps in the coverage, and we design our cabinets as semi-circles to further smooth out the sound wave dispersion. Everyone in the room gets the same sound – even the room boundaries. That makes for a more consistent and palatable soundstage at every seat in the house. No more fighting over the “sweet spot”; it’s everywhere!
