For ht?

You will always need a good sub or two..

Hello,

Is that with a sub, in your opinion?

Thanks!

get RF-83s all the way around. That will sound better than THX.

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.

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!

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.

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...

Detailed Description

Engineered to save space, the new KPT-325 is only 12-inches in depth. The system 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.

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.

La Scala II Specifications

frequency response	51Hz-17kHz± 4dB
power handling	100 w max continuous (400 w peak)

hehehehehe

I thik it is more for me to fill in the sides... I played around with it to be a all La Scala...which works too... but the fill factor was not right. (for surrounds, I think I prefered the KS 525's for movies to spray it a bit. Timbre wise always use the same three up front!)

I could put the tops of the La scalas up there... but what to do with the bottoms is the problem in a 17' wide room..??

But the sounds going behind you in 7.1 say as a plane flies over is just awesome....in 7.1.

I still play around some.. but if you come out here in June, stop by for sure and hear for yourself.....

Sunburn...

Consider I have in my dedicated HT

7 La Scalas

Ka 1000 amp with 2 of the THX subs

And 2 of the THX side surrounds

all in a 17 x 28 roughly room. 106" screen

It's very dynamic, as I am sure you feel it in yours too. People outside this hobby drool when they come over to your place I bet? They do in mine!

The 650's might be more directional, and should have some higher highs maybe? Especially 3 up front and 2 in the back? That said... hard to move away from the classic Heritage sound if you like it? I doubt either of us are losing any sleep over this? hahahahahaha

Enjoy the day!

IndyKlipschFan:

Allthough I would be suprised if the Klipsch THX system could compete with my Heritage based setup !
Seriously
Droopy...
Seriously, you can come here and get a demo of a little of both.. hehehehehehehehe
It is just different.. I wish I could get the three 650's up front for a demo too someday? Maybe someone in Indy who orders them, will bring em over to see? But if you like that K horn / La Scala dynamic sound... Hard to go to something different. A jube system?? Again, the wow factor is off the charts as well.
I will say this... That newer palladium system is just awesome... That in any HT will ROCK!

After reading the specs of the THX system again , I feel I must change my initial response of being suprised if the THX set up could compete with my Heritage based set up .

I must now say , no how , no way could it compete ! OK , so the satellites have a tiny bit better frequency response than my Belles . The efficiency is way down and my sub will dig deeper . As far as space considerations go the THX system wins though .

Now assuming we add music into the equation ...

ensmarcum:

Yeah I do have a good setup. I am not using the subs, they are in their boxes hopefully someone will buy them. So I am looking to get either the THX setup or to go with like the rf63's and rc64 and forgo the sub for now. I dont quite understand what you mean by I am on the right track, and then saying she may thank me later? Is the THX better? Thanks

Not using the subs? Forgo the subs?? In a mostly HT system??? Next to your center channel, your sub makes the most impact in a HT. Don't think for a minute that your mains are handling the LFE adequately.

Re: THX or Reference Line?

AV Theater Designs — Mon, 19 May 2008 16:44:45 GMT

The THX System produces a LOT of sound. It is really designed for a dedicated home theater and hopefully a lot of sound proofing. I would not recommend using one in a family or living room environment unless you are the only one living in the house. When played at mid to high levels you would rock the house and most likely the neighbors. It’s really hard to play the system soft also, it’s kind of like driving a Ferrari and only being able to go 55 MPH. Not very fun now is it?

In our THX Demo room, the room was built with plywood and then drywall and soundproofed and insulated to the max. When played at a loud level you can still hear the room 2 stores down from us. We cannot demo the room to its full potential during business hours but after 6 pm when other tenants leave.

Just something to think about when going with the THX Ultra 2 system.

BTW Our room is 18 by 20 and they sound great. I would not go much smaller then that with the THX System.
