Wow we might have a new reference room here for Heritage! Artto look out!

Where are u from?

Why not use Heritage for side n rear surrounds as well?

Can u enlighten us with your room dimensions and equipment you use?

What was the room designed for this or did you re design it for this? How far back, and what type of seats do you use?

Pretty safe to say you have a perf screen too? How Big?

What was the La Scala mod as well? We have seen some wild variations on here...

BTW,
Amy is your friend, not your enemy. She will look into this for you,
she has helped a lot of us through our own trials with Klipsch.

Let's see what she, (and Klipsch) comes up with.

BTW,
your 2-3 posts in here.... A lot of "Klipsch Fanatics" might be able to
help you now or down the line too.. Let us get to know you as well...

Another Heritage theater convert here! Welcome to the madness!

Roger...

OK, I had to re post here...LOL

A few quick answers and I will post more as I can.

This room is in Wisconsin not too far from Minneapolis.

Ceiling speakers worked out best for the surround and rear channels. I'll have to post more photos. The room is not all 16 feet high.

The room is 22 feet wide and 22 or more feet deep.

I'm using eight amp channels now (7.1) but I have two DEQX processors and will tri-amp LCR for a total of 14 amplified speaker channels.

This room was a "great room" in the center of the house. I'll have to talk more about the extensive window treatments.

I've got seats from Hjellegjerde about 12 feet from the screen.

The acoustically transparent screen is from Seymour AV. It is 16x9 95" wide (110" diagonal). I'm considering a change to 105" wide and 2.35:1.

The LaScala on the IB sub is altered only on the bottom. I'll post some more photos soon.

 geepers, is that glass behind all those curtains?

Details on what looks like a supraLaScala in the center? 

Whats on the back/side walls?

Welcome to the Madness indeed!

Michael

Well it was all glass. The upper deck windows and the lower corner windows are plugged (glass still in place) on the inside with two layers of 1/2" MDF with "Green Glue" damping compound in between the layers. There is six inches of dead air space from the plug panels to the glass. The very heavy window plugs are resting on felt seals and are sealed in the openings with vinyl foam in a can. The remaining "see through" windows have inside windows from: SoundProofWindows.

The theater can barely be heard standing right next to the house outdoors.

The back and side walls are covered with 3/4 inch clear Oak tongue and groove boards.

Is that sub UNDER the house?? How do you keep moisture/temp extremes from damaging it??

Yes, this Infinite baffle sub uses the crawl space under the house as what would normally be the speaker box. The space is very big, hence the IB name.

The crawl space is sealed and stays between 55 and 65 degrees all year round. The relative humidity hangs around 55%. The speaker cones are sealed on the side facing into the crawl space.

Have a look here: Infinitely Baffled

My goodness hulkss where have you been hiding all these years… or have you been here before? System looks awesome alright. Very clean to. Totally awesome.

And I am happy just thinking about the day in the future when I replace my RC35 to RC64.. gees.. I think everyone here would do anything, I mean anything, just to have a little listen to your HT.

You are teasing us with the photo’s here and photo there saga. We all cant wait to see it all… stop teasing. WOW…. Congratulations on a wonderful system..

What is the black thing up center on the ceiling?

Can u take a pic the other direction fron the center out into the room too?

Wow that seems like a HUGE room...

Maybe Heritage sides n rears are necessary? hmmmm Looks outstanding from your pics though... WOW...

The "black thing" is a Panasonic PT-AE3000 projector. I guess it kinda looks like something mounted on the front wall.

I'll take some more pictures this weekend.

The room is about 6000 cubic feet. The back part behind the seats has an 8 foot ceiling height.

These Klipsch KL-7502-THX and KS-7502-THX ceiling speakers were working great until an amplifier failure literally smoked 'em

Thanks for the compliments. I gotta say Khorns sound mighty fine in a big room like this. But the IB sub really compliments them. NO BASS SHAKERS NEEDED.

The IB sub is amazing. I had to do a complete departure from my normal listening habits and buy some pipe organ SACD's. A number of pipe organs exist with 32 foot pipes that play down to 16 Hz. A few are even bigger and go lower. The biggest is 64' at 8 Hz.

The sub has four of these: IB15

That sub looks and probably sounds rediculous (in a great way). Four 15's? Wow, that's gotta sound sweet.

The "black thing" is a Panasonic PT-AE3000 projector.

Great projector. I did not even recognize it myself in your photo. I thought it was something mounted to the ceiling but I could not tell it was the panny. I just got mine a few weeks ago and love it.

Saw those sides n rears at the Klipsch get together in Indy... Wow.. You have a huge room too?

How they ever really kept up with your fronts is amazing to me... Even at THX Ultra II certifications... Your room is HUGE....

Glad you were happy with them, I use the 525's as side surrounds in my HT. They have to be cranked to keep up but seem to do the trick here...

My Dream?

Now if someone ever trades these in... I would love to be the first to see how they do here.....LOL

KPT-12-VB


KPT-12-VB Cinema surround speaker



The
Klipsch KPT-12-VB is a high output, ultra wide coverage cinema surround
channel speaker system that brings a new level of seamless ambience and
envelopment to the sound image in medium to large-sized auditoriums.



Features


  • Virtual Boundary Array Technology (VBAT)

  • Dual Skewed horn design provides coverage in excess of 140° in the horizontal; reduces required speakers by 50%

  • 12-inch woofer for deep bass and high power handling

  • Threaded inserts to accommodate industry standard fittings








Detailed Description


Continuing
to advance Klipsch's technological leadership position, this patented
Virtual Boundary Array Technology (VBAT) loudspeaker reduces the
required number of surround speakers typically used in today's
conventional surround channel array by 50%.

This exciting new
technology uses a pair of our patented skewed horns in a side by side
configuration that provides coverage in excess of 140 degrees in the
horizontal. The result is consistent coverage over a much wider area
than was previously possible with a single horn. These new horns also
have a tighter 60-degree vertical pattern for greater distance
throw—better suited to today's wider auditoriums.

The large
voice coil 12-inch woofer and pair of 1.75-inch titanium diaphragm
compression drivers give the KPT-12-VB truly prodigious power handling.
When combined with 100dB sensitivity, the result is truly effortless
reproduction of the tremendous dynamic range present in today's digital
sound tracks.

The system's durable enclosure features an angled
15-degree down-firing front baffle and rear panel equipped with
threaded inserts to accommodate industry-standard brackets. This
facilitates quick, simple and secure installation. The top mounted two
point barrier strip provides easy access for hookup after installation.

The
KPT-12-VB incorporates the standard SMPTE/ISO 2696 X-curve into its
response and is capable of a solid 40Hz in-room response, further
enhancing the realism in the digitally mastered effects channels.

An
array of KPT-12-VB's have an uncanny ability to localize and track
directional effects and provide seamless envelopment, setting a new
standard for the suspension of disbelief in the movie going experience.

How they ever really kept up with your fronts is amazing to me... Even at THX Ultra II certifications... Your room is HUGE....

When I set the system up the rears needed about 10 times more gain than the fronts. The rear ceiling speakers are not playing below 80 Hz (THX recommended x-over point) so even with 10 times more gain there is less average power going to them.
