Do you think it would be worth the upgrade ?

What would be your reason for the upgrade? Are you running out of headroom? If not, I see no reason to upgrade.

Good to see JTR people with opposite views( about power anyway).
I feel any time you get a chance to double your watts than do it.
That is why I love my 12s, they take more than what I can give
them and say "thank you may I please have more".
I have read where peolpe state that it does not matter your total watts
becauase you only get 5 watts whether your amp can produce 200w or 400w.
I do not understand that aurgument because:
using XPA-5 VS XPR-5 as an example,
In my system if using a XPA-5 to power then replacing it with the XPR-5, essentially doubling
the rated power,
If I am plugging it in the same power outlet and just replacing an amp for an amp, would it not
draw more watts. Mabey not double but definitely more.
I might be wrong but you will not know till you try it. If you do, please report your thoughts back because
I would be interested in your overview.There is nothing like first hand experience.
For me I cant wait to see the XPR-1 1000 watts at 8ohm and 2000 watts at 4ohm.
My 12s might cry "uncle" at that time.
Till then I am going to keep trying.
I LOVE MORE POWER!!!

The general idea is you don't need to upgrade from 200W to 400W if all you use is 5W. Speakers don't simply draw power; there's a volume knob under your control.

Unless you have a really big room and play really loud I don't think it is needed. This is one of the benefits of having HE speakers. smile.gif

In testing my T12s I didn't see any difference between my Outlaw 770, Emotiva XPA-3 and the QSC GX5 amps in either the frequency response or (realistic) volume capacity. I forget how loud I was testing the volume but it was over 100 db.

I'm one of the guys that will buy as much power as humanly possible....just because. I'd buy the XPR-5 just based on looks alone! It's a beautiful amp IMO. I currently run a D-sonic ICE 7 channel amp and have a few 1000 watt monos as well. If money is not a huge concern, I'd go with the XPR-5....because it's cooler cool.gif
post #4477 of 18717
I am guilty of having more power than needed as well. My array is 110 dB sensitive and I have a 500 watt amp powering them. It is also stable into 2 ohms at 650 watts which is also not needed.

post #4479 of 18717
I love power like I stated earlier but I would like to clear that statement up a bit
I am not interested in big overbearing pro audio amps or even emotiva mono blocks.
The size and weight of those as seperates are just to big and take up to much space.
I have 3 20amp circuits so my main amp gets 1 dedicated and thats all. no more.
If it was not for the D-sonic ICE amps I do not know how I would feel on the size to power
trade off. I can have a seven channel amp with as much as 500watts 8ohm 1000watts 4ohm
weighing in at 50 lbs and taking up one shelf in my cabinet same size as my receiver. It uses
1 20 amp outlet leaving me 2 more for all other equipment. I can easily make that work with no
problems. The D-sonic amp is sweet in every way running cool and sound quality is excellent.
It really drives my 12s great. It is also a VERY noticable difference in everything that counts over
my XPA-3 and XPA-2 . Those amps work just fine but there is a superior difference between the
class d and Emos amps.
I am not BIGGER IS BETTER for the sake of size but more
"better" sound with a " wider soundstage" usually comes from "bigger" products.
Just how it is.
My goal is simple:
make IMAX try harder.
I love my Triple 12s

any questions I will answer.

When going with very high-gain amps with very sensitive speakers such as the T12, I'd suggest seeking out an amp with a gain controls. Otherwise, you've got the real possibility of hiss problems in a quiet room.

I get hiss with Quituples and Bob Carver Signature Grand Cinema amp. That's 810 wpc @ 4 ohms and no gain control on amp. It mostly happens with TV programs and some with movies.

Interesting. i've got the TGA 7400 and no hiss. I am not using the XLR inputs ntil I updgarde my pre pro. Right now I use UMC-1 and it does not have xlr outs except for the sub. Even running the RCA's (3 ft long each) there is no audible hiss, the noise floor on my T12's can only be heard with your ear about a 6-12 inches away with the rest of the room dead quiet. Will this noise floor drop even more with the XLR's?

I know its not recommended and seems a shame to have to do
but plugging a $3700.00 amp into a $1.25 cheater plug worked for me.
I did not want to do it but after fighting with that hum for 2 weeks
and eventually blowing my sc-37 sky high I was out of simple self made fixes.
Out of frustration,I went to the hardware store and got 2 for $1.25.
That was seven months ago and it still works. I will never be comfortable with
this situation but for now it works perfect.
At least I ended up with a 4311 and xt32.

Using another HE speaker design (100dB sensitivity), I found that the preamp or surround processor affects the hiss level as much or more than the amp.

I disconnected my Innersound ESL from the surround processor and away went the hiss! I also own Sunfire amps and they are dead quiet from the LP until you connect them to a less than stellar source (preamp)

Consider the source... biggrin.gif (could not resist!)

My D-sonic amp is dead quite on my T12's. My Emotiva XPA-5 did have some hiss but it wasn't that bad.

Also consider that even on the xpa-5 and my listening position, audyssey has trouble dropping the level of my speakers enough to EQ them properly. I had to back my speakers off further behind my screen to keep audyssey from knocking them down to -12db each, which is the floor, and screws up the testing if you get there. with close to double the wattage on the xpr-5 this most certainly should be an issue, unless you are listening from 20feet away. (my source is a 4311 as well)

N8, can you comment on your move from the emo amp to the d-sonic? Id love to hear your impressions!!!
post #4488 of 18717
I believe that emotiva reduced the gain by 3 db on the XPR series vs the XPA. 29db on the XPR vs 32 on the XPA

Figured I should drop in and introduce myself. I've been lurking on all the JTR threads for quite some time now and about a month ago pulled the trigger on a complete setup to overhaul my theater. I've been running Paradigm studio 100's in my dedicated theater for a few years now and have never been completely happy with them. Driven with an Emotiva xpa-3 they just couldn't handle reference movies without getting harsh and unlistenable. They are okay for music but again, not at any above average volume. The tweeters are definitively bright as well. My biggest issue is with the center channel (old V3 cc570) which can't keep up at all especially on concert blurays.

In order to remedy this situation I have ordered the following:

3X Triple 12 HT
2X single 8HT
2X slant 8 HT
1X orbit shifter
The LCR will each get it's own bridged crown xls1500 while the front wide single 8's will get an xls1500 running stereo. The rears will run off my 4311 as well as future highs.
Jeff is building me a custom center stand so I can lay the center on it's side under my 126" screen with a 10º upward angle.

I will also continue running my DIY dual opposed 15 but will likely end up having it handle the under 20Hz content only and let the shifter handle everything else.

Everything is projected to ship next week so I'm getting pretty excited. I live in Canada but just a few minutes from the border so I will be bringing them across the border myself to save on shipping. Getting them loaded and into the basement will be an adventure.

Kudos and congrats, that's some monster system you just got yourself!
Enjoy.

They don't really sound much different...until you get to extremely loud volumes, then the ICE amps really stand out on the control over the T12's and alike. I also have a set of Red Dragon 1000ASP's and they have been running my T12's since I got them. I LOVE ICE amps. Any problems are easily fixed with a module swap, they are light and will take anything I can throw at it and breeze through it. My XPA-5 had served me very well in the time I had it. If I didn't have the D-sonic, I'd have the XPR-5. The only real problem I ever had with any emo amp I've had (xpa-5 x 2, xpa-2, upa 5)
was the high gain and how it really didn't match up to well with the HS speakers. I'm happy with my D-sonic and Dennis was really great to deal with. I'd recommend D-sonic to anyone. Very nice looking and well built amps.

Can't wait to hear the impressions on this set up. Should be outstanding! With the 12's and amps you are running up front I think you made the right decision with the orbit shifter. Please post impressions and pics when you can.

congrats subyguy . Look forward to hearing your impressions and any pictures.

Yup, I'll try and survive with the one for now but it's a compromise:) I do have a very big room that is open through a hallway to the rest of the basement so I may end up with two eventually depending on how integrating my dual 15's for the low end works. If I install a door to seal the theater room it would make a big difference as well. The theater portion is 4000cuft alone plus the rest of the basement and stairway so we'll see.

My truckload of ATS accoustics panels arrived a while ago so I have that to occupy me for a bit. Deadening the room has really showed the weakness of the paradigm setup. Killing some of the room issues allows me to turn it up quite a bit to where the studio 100's compress and the center falls on it's face hard. I sold my xpa3 and temporarily hooked a crown up to my LCR so I have to be pretty delicate with the volume or risk turning the pradigms into a pile of hot goo.

Now I'm busy searching for the best remotely triggered power option to power up my 4 xls1500's and ep4000 with my Ipad Irule remote. Add the OS amp and 4311 and the power company is going to love me but I'll finally put my two dedicated 20amp circuits to good use.

I also picked up a balanced mini dsp to use to low pass the dual 15's and be able to work on the crossover to the OS. Jeff figured it should work OK but I'm sure it will take some time to optimize.

Nothing green about that setup of yours except the green with envy color of friends when they hear/feel the system wink.gif. With good placement,I'm sure you will be able to get by just fine with a single OS. Mine were the first OS's and there was an issue with the first run of amps so while Speaker Power was repairing them I was down to one OS. Honestly, any difference in SQ and output was negligible. Two may be nice but a single OS and your dual 15's should fill just about any space with bass.

The door for the HT room is a good idea. With that opening I think you will find that the bass will find it's way to the adjacent room(s) and will seem much hotter than in your Theater room.

Good stuff and let see some pics when you get it all setup.cool.gif

I had the good fortune to be near the town in Wisconsin that JTR calls home today. Jeff was nice enough to take some time to demo the triple 8's and the Cap 1000. All I have to say is "wow!". Everything was so clear it was unreal. I've never heard anything like it. He started out with the gunfight from "Open Range". I was surprised that he picked that scene as I had seen it several times and didn't think that it would be a great demo for the speakers. Man was I wrong. The sound created such an emersive experience, I was riveted, even though I knew exactly what was going to happen. One great moment in the demo was when a bullet was shot towards the screen and my hair was ruffled by the Cap 1000. Talk about 4d. I think the fact that I was familiar with the movie and didn't think of it as "demo" material made it a great choice. We also listened to several music tracks and they were just as impressive. I was sold on the CHT sho-10's before I went into JTR's office. Now, assuming that the costs for finishing my basement do get out of control, I'm going with the Triple 8's. Thanks Jeff!

Listening before you buy is always a good idea. Your room may sound different, but at least you have a benchmark. I was able to hear my speakers before I purchased and it was the incredible dynamics that got me hooked.
Good luck with your HT room build, I'm sure it will give your family and friends many happy times. cool.gif
post #4500 of 18717
Hello Everyone! I have had my JTRs for about a week now and its safe to say I completely love them. It's all been said before but the effortless volume and dynamic capability of these speakers are amazing. The clarity, sound-stage and imaging really wow me! There are times where it seems as if there are no walls and sound comes from everywhere. These points combined make for a far more cinematic experience than I had previously. It's also confirmed for me now that I was pushing my previous speakers towards there limits(for sounding right anyways). At or near reference volumes have gone from very edgy and thin to smooth and huge! Its nice not to worry about over driving one's equipment, for my tastes these are "IT" ! smile.gif

JTR.jpg

Other speakers used:
Chase PRO-10 surrounds
Axiom Qs8 rears
4-18" IB sub
