The Certification Process
As romantic as it sounds, manufacturers do not simply submit
a product to THX for testing and then get a yea or nay. A THX product
starts with the manufacturer purchasing the expensive and confidential THX Design Manual for
the product in question. THX products are designed to be THX products.
The manufacturer knows what they have to do from square one. Once they
have a working sample, it is sent to THX where it is tested, for a fee, and either
checks out and a license granted, or it is sent back with a report on what
needs to be addressed. THX tells us that they have yet to receive a product which
got everything 100% right on the first try.
Licensees then pay a small per-unit license fee
for the manufactured product.
I hope everyone can
appreciate why, to this day, the particulars of THX's criteria are not
public. They are a business like any other and they need to protect
their intellectual property. If everything was out in the open, people
could just say, "It meets or beats the THX criteria", and THX would get
nothing. They'd fold, and we'd never get all the benefits they've brought
this industry over the years.
Myth: "THX
restricts manufacturers in terms of their design creativity."
Reality: Nothing could be further from the truth!

When asked why their product is not THX certified, some
manufacturers have told us its because they "wanted to do things THX does
not allow". In terms of speakers, there is indeed not a whole lot of
latitude (no full-range models for example), but when it comes to electronics, that's nonsense. THX requires that a piece perform to
their spec (or exceed it) and that it do what it is supposed to do when the
THX mode is engaged. Manufacturers are free to offer exotic decoding
schemes, try innovative things like room EQ (such as the Audyssey system in
some recent THX receivers), or offer crossover options other than the standard THX
(because not every customer is going to have THX speakers). Lack of
THX certification in
higher-end electronics (where cost is supposed to be no object) may be an indication that the manufacturer is not
willing to make a competent product, or that they just don't feel their
customer is interested in certification.
Nick Platsis from Anthem Audio Video:
"The THX Ultra2 spec has tougher standards
compared to the other licensing bodies, for example higher output swings are
required, especially for the subwoofer channel. On the video side, no one else
tests it. It's good that someone does, for example some manufacturers may
take the bandwidth of a video switch and try to pass that on as the
bandwidth of the whole circuit from input jack to output jack. Regardless,
it's not difficult to meet any of these standards unless attempting to do it
on the cheap or there's an element of laziness somewhere.
The challenge is integrating every single
option that THX, Dolby, and DTS have to offer while maintaining user
friendly operation and preventing conflicts between the various
requirements. Then, when more processing options appear on the scene, it
starts all over. Luckily, the people at THX are great to work with."
Other Areas of Interest
In recent years, THX has branched out into other markets as
well as continually revitalizing existing ones.
On the professional side, THX has implemented PM3, their
Professional Multi-channel Mixing and Monitoring
program.
THX has also become active in the PC Computer market.
While the THX Computer was something of a flop, THX PC Speakers are very well respected.
There isn't really an industry standard for PC sound like their is for movie
sound, so what THX is doing with PC speakers is basically saying that at a
given price, a product is as good as it can be, basically giving you some
assurance you're not being ripped off, and it takes away your need to try and
decipher specs (which in the PC Speaker market are practically useless).
Perhaps more interestingly, THX has gotten involved with
computer/PC Game development. The production values of computer and
console games have risen tremendously in recent years, in some cases rivaling
Hollywood, but the industry at large has grown up largely without the
benefits of standards. It has taken THX to come in and infuse the
industry with the concept of consistent and performance-oriented
presentation. For the first time, the person doing the raw art, sound
bites, 3D environments, or what have you, can be assured that the effort they
put into their work will be realized right to the end because everybody's
workstations, environments, and equipment are all set up to the same
consistent standards. Room acoustics, background noise, room lighting,
every piece of audio and video equipment, all must meet certain THX
performance requirements.
THX has also been contracted to design Car Audio systems for
Lincoln. The pieces and bits are manufactured to THX design and spec
by Ford sub-contractors. They have a full time staff in Detroit to handle
this project with several THX home office engineers working on auto projects
as needed.
Looking Forward
We are assured that THX is very busy with new projects, and
there are aspects of the industry we know could use their help.
In the works is a program which makes it possible to have a home theater itself THX
certified (as opposed to just the equipment in it), which although the
province of only the most wealthy, is an awfully cool notion. If you
have a spare $250,000 or so, a THX Reference theater can be yours in about 12
months. Standard theaters should come in in the $50,000 range and will be
possible in about 18 months. These theaters require THX gear (d'uh!) and
must be built to THX-approved plans and tested to meet THX performance
minimums for both audio and video. The big difference between reference and
standard will be in video requirements and sound isolation, both of which
get quite expensive quite fast.
Conclusions
I would be remiss if anyone came away from this essay with
the impression that Secrets endorses everything THX does or that we feel anything
non-THX is intrinsically inferior.
I do hope we've given you a better understanding of
THX, enabling you to decide if THX is for you. I cannot stress enough
that it never "hurts" for a piece to be THX-certified, except that
it sometime may costs a little more. Shopping for a system "from scratch"
is an excellent time to consider THX because virtually all of the guesswork
as to what will work with what and how it will work together has been taken
care of for you. At the same time, there is nothing stopping you from
integrating a couple THX pieces, the ones that make the most sense to you,
into an existing system that has non-THX-Certified components.
THX guarantees a lot of very useful features, and if you get
a THX system, then simply plug everything in and press Play, you're going to
get results that are pretty close to acceptable. If you actually then
further calibrate and position speakers properly, it'll almost certainly be
excellent. Buying non-THX, most importantly, means that you have far
less of an idea about what you're getting without some homework.
