So You Think Your Room’s Bad, Pt. 6

Six installments in, we’ve arrived at the end of our tale about turning a trade show booth into a reference-quality home cinema space. But we’re not here to pat ourselves on the back. Yes, the demo room ultimately drew scores of visitors, and praise from the people who experienced it.

 

But this series of posts was meant to be inspirational, not self-congratulatory. Our aim was to encourage you to not give up on “problem” spaces until you’ve exhausted all the possibilities. The technology and expertise definitely now exist to turn rooms that would have once been dismissed as impossible into killer luxury home entertainment spaces.

 

Here are the key takeaways:

 

Even rooms with weird dimensions can make for a great home theater

If we had focused all of our design efforts exclusively on performance, there’s no way we would have chosen an overgrown bay window as the geometrical inspiration for our room. The hacked-off corners inside the room were driven by the various needs of the outside of the booth. But with the right choice of gear and some optimization with the speaker placement, we made this kooky space sound great.

to your advantage, see Part 1 and Part 2

 

Choose your speakers carefully—not all luxury speaker systems are made the same

This doesn’t mean that one speaker is necessarily the best answer for all applications. Speaker systems come in all sorts of shapes, sizes, and configurations. Some are designed like audio spotlights. Some deliver a wider swath of sound. Some subwoofers are designed for in-ceiling placement. Of course, if you don’t have attic space to work with, you might opt for in-wall subs, or even discreet in-room subs (like we did). The point is, you shouldn’t just assume that a speaker is a speaker. Find the right solution for your unique room.

Room correction can eliminate a lot of a “bad” room’s worst flaws

It wasn’t that long ago that the room-correction software solutions built into most surround sound systems created more problems than they solved, but in recent years they’ve made monumental improvements. These days, a good room correction system can practically eliminate the need for big bass traps and other gargantuan physical acoustical treatments. And the best of these solutions can even correct for sub-optimal speaker placement.

Acoustic treatments can help solve the problems room correction can’t fix

Since room correction still struggles with some acoustical problems, don’t turn your nose up at physical acoustical treatments. You may find that you can even work these treatments into your interior design.

And maybe most important of all:

 

Creating a premium entertainment space is a team effort, so pick your players wisely

If, for whatever reason, subtle acoustical treatments are an absolute no-no in your luxury entertainment space, encourage your integrator and designer to work together on alternative solutions. A carefully placed bookshelf or even draperies positioned in the right place can work wonders for the sound of your room. But this requires that all of the

GoldenEar’s Jack Shafton on the Finished Booth

 

GoldenEar VP of Marketing & Sales Jack Shafton co-authored the 3rd installment of this series with Dennis Burger. Here’s his reaction to experiencing the completed booth at the CEDIA convention in San Diego this past September:

 

“Upon seeing the finished product when the show opened, I was impressed with how the booth turned out (it looked great and highly functional), and also alarmed by the openness of the demo space. There was already a big crowd milling about the booth (kudos to Kaleidescape) and the theater demo was standing room only. The space was basically open to the show floor, just behind a draped entryway. I waited for the next showing and grabbed a seat before the room filled. I should have known, but the demo of Baby Driver caught me by surprise—this system, in this terrible room, just rocked! And other than the small subs, the sound system was basically invisible. It presented a seamless bubble of sound around and above with pinpoint imaging, and the the subs made the air move with a thunder. Of course I kept thinking ‘louder, make it louder’ because it was fun—although they had chosen a good compromise on volume level. I got the impression after the demo that the other people in the room would have liked to kick back and watch the whole movie!”

players respect one another and their specific design expertise. There will always be some give-and-take. All parties will have to compromise at some point. But if you can find collaborators who know when to hold ‘em and when to fold ‘em, your luxury entertainment space will be all the better for it.

 

If you’re ready to tame a problem space but aren’t sure where to look for help, the Home Technology Association (HTA) can be a great resource. And, by continuing to showcase unusual but successful home entertainment rooms, we at Cineluxe will do whatever we can to lend a hand.

 

Before we wrap this up, we’d like to thank some of the greatest experts in the business—in particular, Jack Shafton at GoldenEar, Jon Herron at Trinnov, and Anthony Grimani at PMI—for making our pitifully small demo room sound way bigger and better than it ever should have. And we’d like to wish all of you luck with turning your own problem rooms into amazing sight and sound experiences.

So You Think Your Room’s Bad, Pt. 3

Dennis BurgerAt the end of our previous post in this series, I teased the fact that one pair of speakers at the back of the room ended up driving the decision-making process for the entire Atmos surround sound speaker system. It’s worth digging a little more deeply into exactly why that’s the case.

So You Think Your Room's Bad, Pt. 3

Just to remind you what the geometry of our demo space looked like, here’s an overhead view of the back of the room. The rear wall is at the top. You can see a rough approximation of what we thought our seating may look like, as well as the canted walls that made the outside of the booth look so great, but crunched us a bit in the demo space.

 

If we had gone with seven ear-level speakers, that would have meant four speakers in the back of the room, at positions marked A and B. But this would have caused problems for anyone sitting in the back row. Someone sitting next to speaker A on one side of the room wouldn’t have really been able to hear speakers A and B on the other side, and the speakers at the front of the room—for dialogue and screen sound effects—would have been drowned out. Sometimes more isn’t necessarily better.

 

What I really needed was a speaker I could position somewhat closer to the points marked C, but a little higher on the wall so as not to overwhelm any one seat in the back row. The extra height was also added to accommodate anyone standing in the back of the room, so they wouldn’t block the surround sound effects for anyone sitting in front.

 

I desperately needed a speaker that would project its sound out into the room authoritatively, while also spreading its sound out less like a spotlight and more like a floodlight. 

 

I also needed an in-wall solution, for reasons discussed in our previous post. One speaker came immediately to mind: GoldenEar Technology’s Invisa MPX MultiPolar in-Wall speaker. The MPX’s bass/midrange drivers don’t point straight out into the room, as do those of most speakers. One of the drivers is rotated a bit to the right, the other a bit to the left. Combine that with the company’s High-Velocity Folded Ribbon tweeter (which squeezes air sort of like an accordion to create low-distortion, room-penetrating high-frequency sounds, rather than pushing air like a normal dome tweeter), and you have the makings of everything I needed here—wide, deep, enveloping sound that wasn’t diffuse.

So You Think Your Room's Bad, Pt. 3

And with that piece of the puzzle solved, the rest of the speaker system started to fall into place. To match the sound of the MPX, I specified three of GoldenEar’s Signature Point Source (SPS) in-walls for the front left, right, and center speakers, and four of the company’s Invisa 650 in-ceilings for the overhead channels.

 

We also had just enough space at the front of the room for subwoofers, so I opted for a pair of SuperSub X subs. Why two subs for such a small space? It wasn’t so much about producing enough volume as it was about delivering rich, even bass in such a weird acoustical environment and making sure every seat in the room experienced the same level of bass.

 

With those decisions made, I called GoldenEar’s Vice President of Marketing and Sales, Jack Shafton, and asked him if I could take him on a virtual tour of our most current 3D design for the booth. I wanted a second opinion from an industry expert, just to make sure I had made the right choices given such compromises. I also wanted his advice on exact speaker placement.

 

Here’s Jack with his reactions to seeing the 3D renderings for the first time, along with some thoughts on what makes GoldenEar’s architectural speakers unique:

Jack Shafton: When Dennis shared his plan for this booth at CEDIA, my first reaction was, “YIKES!” GoldenEar always uses a fully enclosed sound room for our own trade-show demos, so this was certainly a new challenge. We agreed that this room would never be ideal, but could certainly be done effectively using the Invisa speakers and SuperSubs. Dennis hit on one of the reasons the Invisa MPX was such a good choice: It’s a direct radiator (important for today’s surround formats) with very wide dispersion. But I would also mention that the power handling and efficiency of the speaker are of great importance given the semi-open nature of this sound room.

 

That’s just one speaker, though (well, two in the case of this room). As for why GoldenEar’s Invisa speakers were the right choice overall, remember that this system needed to impress consumer electronics industry members, not the average consumer who has never heard a great-sounding home theater. One thing that I think sets our in-wall and in-ceiling speakers apart is that we design them using the same drivers and technology employed in our award-winning Triton tower speakers. There is no good/better/best stratification in the GoldenEar architectural speaker lineup; just the best of everything we do. The folded-ribbon tweeter offers exceptional dispersion, amazing fidelity, and great power handling, and it is found in every Invisa speaker. Combine that with our mid/bass driver

technology, crossover design, and GoldenEar speaker voicing, and the result is exactly what Dennis needed to blow people away in a space that had no business sounding as good as it did. Of course, the two SuperSubs helped a lot, as they provide big sub performance in a tiny, vibration-cancelling design.

 

 

DB again: In addition to confirming my speaker choices, Jack gave me some helpful advice in terms of placement, especially of the front speakers and overhead channels. That guidance was invaluable given the weird geometry of the room. Mind you, the odds you’ll be installing a cinema sound system in a room as compromised as ours are slim. The lesson to be learned here is that when taming a problematic home cinema space, you’ll sometimes find that solving your most daunting problems first makes all of the other pieces fall into place.

 

Still, as amazing as GoldenEar’s speakers are, if we had merely slapped them in the walls and ceilings and provided them with power, they wouldn’t have sounded their best. In our next post, I’ll be discussing how Trinnov’s Altitude 16 home theater preamp/optimizer helped us tame some of the room’s worst acoustical problems and give the GoldenEar speakers room to shine.
