Calibrate it All!

Is it worth doing a specialty audio calibration in areas of a residence outside the dedicated theater? Absolutely! 

Getting the spectral balance, bass management, and time synchronization of audio systems tuned for each and every environment is a pretty simple and cost effective way to upgrade the sonic experience. You can get good dialog clarity, smooth bass, and a reasonably good spatial rendition with an hour or two spent in every space. You do need to have some digital EQ functionality in the system, and that is getting pretty easy these days. I am not talking about auto-EQ, which I contend still doesn’t work right (unfortunately). I mean some number of bands of EQ for each channel that you can adjust while monitoring an analyzer application running on a laptop. That function is available in a number of multichannel amps (Sonance, Ashly, Powersoft, to name a few), in a number of receivers and decoders, and of course, as stand-along EQ devices placed between the switcher/preamp, and the amplification stage. Even in environments that acoustically very live, the end result is well worth the time invested.

Here’s a grab bag of pictures of projects I tuned in the past month using EQ, time, and care. You’ll see a specialty “fun room” with Atmos immersive audio and 4K video, but also a kitchen with ceiling speakers, a large backyard with bollards, a few simple media rooms and a bedroom. In all cases, the clients clearly heard a vast improvement, stating that the dialog was clearer, the sound more dynamic, warmer, more engaging, and a number of other plain English adjectives. Bottom line is that all were happy with the results and with the invested dollars.

A very nice "Fun Room" with 4K UHD Video and Atmos Immersive sound!







A simple 5.1 channel TV room. Dialog and effects sound a lot better after calibration!





The kitchen: center of all home life. Music and broadcasts come alive after tuning the ceiling speakers!



The backyard sound system went from edgy to smooth in less than an hour!






Voice clarity and sonic envelopment are much better thanks to EQ and proper delay settings!







These small media rooms went from mid-fi to hi-fi thanks to calibration work!

THE GRIMANI FILES: Bringing Life to a Comatose Home Theater

This client was referred to us by the integrator, who completed this installation about 10 years ago. The room was a dedicated three-row home theater in an upscale neighborhood of Detroit. All the gear was state-of-the-art for its time - from the studio-grade speakers, to the professional HD video projection system. But the surround decoder finally gave up the ghost after several years of faithful service. The client heard that Dolby Atmos® was the latest thing, so he sourced a new processor. He expected it to be an automatic upgrade, but wasn’t aware that he also needed to add speakers for the Top and Wide locations. At any rate, it was time to install, configure, and tune the system for the new processor. I took the job and carved out two days - right before Christmas - for a quick jaunt from my temperate San Francisco Bay Area home to frigid Detroit. (Who doesn't like a little cold for the holidays?) While planning the trip, I found out that the system didn’t include any

Dedicated High Performance -- CEDIA 2016 Design Awards Winner

In this industry, we regularly cater to “enthusiast” clients who are very enthralled with the idea of a fully engineered and commissioned private cinema. They may have played wit h speakers and receivers in their spare time. They may have preconceived notions about what makes speakers work or not work. They may even want to tell the crew how to go about doing the wiring and installation. This client just built his Tuscan dream home in the rolling hills over Newport Beach, California. He wanted a great place to enjoy concert videos and movies from all around the world. He got that and a lot more in an acoustically treated and tuned room with appropriate sound isolation, Dolby Atmos immersive audio, 4K video, and a luxury-grade interior finish. The room was to be laid out as a formal dedicated two-row theater, without many design frills, and with maximized return on investment for the equipment. The client decided not to adopt the customary stretched fabric dress in order to put mor

Home Theater Has Come Out of the Cave

Welcome to the Fun Room Light, bright, and inviting. Walls & Ceiling look like drywall Comfortable seating for friends and family. Glass wall visually connects the Fun Room and Courtyard  High Points Think beyond the theater box Great entertainment can be in nearly any space New technology provides more flexibility New design solutions open the door for Interior Designers Overview Good news! With the latest technologies, we can move past the dark and secluded home theaters of the late 20th century! No more man caves isolated from the rest of the house. No more rows of theater seats formally lined up, as if ready for battle with action heroes. Imagine even having a glass wall or window so we can stay connected to the rest of the world? Instead of just a "Home Theater", we want a "Fun Room". But, and this is a big but, can we still have all of this and a great cinematic experience? The answer is Yes , and
