THX or Reference Line?

Recommended Posts

For the dreamers in here.... my neighbor is but a few weeks away with three of these up front...

http://www.klipsch.com/media/products/cut-sheets/kpt-325-cut-sheet-080326.pdf

Drool... I think???? I cant wait to hear them.. He is using 4 subs...so 2 of the Klipsch THX KA 1000 amps and 4 of the THX 120 subs too.

His room is "Architechtual Digest" material... So all the side and rear surrounds are the THX KS and KL 7800 Inwalls from Klipsch.

I am very happy I steered him down this path, I can't wait to see n hear the results.. If he allows it I will post some pics.. It will be the fanciest dedicated HT theater I have ever been in I am sure.

I would love to get a A vs B on this though.... Granted, I have the older La Scalas too...

Klipsch 325...

features the KPT-315-LF single, 15-inch woofer enclosure coupled with
the KPT-904-HF Tractrix® Horn. Amazingly, this compact combination
delivers the same frequency response as the KPT-904 system. The KPT-325
is available with or without a passive crossover.

vs
La Scala...

Detailed Description



Even though the La Scala II adopts a more finished appearance, it
still delivers the same sparkling highs, extreme output and unsurpassed
low distortion bass response as the original design. It also continues
to utilize the same horn-loaded drivers as the Klipschorn, making it
highly efficient and able to produce high volumes consuming very little
power and undetectable distortion.


When the La Scala first launched in 1963, audio pioneer Paul W.
Klipsch made it for Arkansas gubernatorial candidate Winthrop
Rockefeller to use as a public address speaker. Because some considered
it a "portable" and more affordable version of the revolutionary
Klipschorn®, the La Scala found success beyond the campaign. Despite
its raw, unfinished appearance, the fully horn-loaded, three-way La
Scala sounded so good people still wanted to put it in their living
rooms.


Remaining virtually unchanged since those early campaign days,
Klipsch decided to cosmetically improve the raw-looking La Scala by
totally redesigning the way the cabinet was constructed. The goal was
the achieve a more finished appearance and improve cabinet rigidity. It
is now available in a variety of high-quality wood veneer finishes,
including cherry, walnut and black ash. The La Scala II also includes a
grille to cover the mid and high frequency horns. The bass horn cabinet
walls are now constructed of 1-inch thick MDF rather than ¾-inch
plywood to offer more support, decrease resonance and deliver cleaner
bass response.

Thanks Roger .

BTW , I find it hard to believe you need the side surrounds . My set up is in a 16 x 22 room and I have no need to step up to 7.1 . 5.1 will overload the room just fine at about 120 db !



I agree with you also that 5.1 can fill a room no problem. But with Blu-Ray
now encoding a lot of the discs in 7.1 it sure would be nice to be able to take
advantage of this. If you have ever heard a really nice 7.1 home theater with a
true 7.1 decoded disc it’s a pretty amazing experience. Our THX Theater is 5.1
and not big enough for a 7.1 set up but I really wish I had the room to add in
the rear surrounds. We just did a 7.1 with the THX In-walls and played
Hairspray Blu-ray and it was truly awesome.

I was at Roger's last weekend watching Cloverfields and there were a couple times where his THX surround really came to life. Purpose-built surrounds in the correct position do much more good in his theater than another set of LSIsplits in the rear corners. It's all about placment, and the processor makes up the difference in timing and volume.

It works very well for Roger and I've heard a ton of home theaters. Good move Roger!

Your very gracious Michael..

I know there is a "Science"...and a "ART" to all of this.. If I can be so bold to say this too.... A little "luck factor" as well in getting all of your equipment to work together interface wise to bring the best out of each step of the process.

I know in "Flight of the Phoenix," when that plane flies over you, it really feels like it, especially with those two big props spinning...

In "Cloverfield" on the bridge scene where cables are splitting all around you and behind too...And that bridge gives out in front of you...YOU FEEL like your on that bridge for sure!

Even in the THX blue exploding ball when it explodes through you....it feels like it was shot through you because of the rear speaker too.

Movies in DD EX and DTS ES go even farther. And with Blue Ray looks like more coming out in 7.1.

Like the AV guy said.. Set up well, you just get immursed in the whole story...... And that is the point.
