Insufficient bass headroom: The bass peaks just aren’t loud enough for full impact
It’s simple; you need to play at least 110dB of clean and tight bass in a home cinema to get listeners to crack a smile. Many home theaters have plainly anemic bass that tops out at 90dB; barely enough to get any reaction.
It takes horsepower and tuning: You need enough cone area, enough amplifier power, and multiple subwoofers that are placed for maximized room gain efficiency. And then you need to carefully tune the relative delays, EQs and levels of the subs until you squeeze every little once of sound pressure across the range from 20Hz to 100Hz out of them. You need a spectrum analyzer, the right test signals, the right engineering talent, and some time to make it all happen.
Grimani Systems Solution:
Our CinemaOne and CinemaTwo systems comprise four high-SPL powered subwoofers with plenty of excursion, plenty of amplifier power, and effective room tuning capabilities to optimize the coupling of the bass energy to the room. With independent tuning of level, delay, and EQ of four subwoofers in a room, we can sometimes find upward of 12dB of extra sound level gain! Our field engineers tune the systems for you, using the most advanced electroacoustic tools coupled with years of experience in fine audio performance.
