Official JTR speaker thread - Page 157

What sort of spl numbers are you guys hitting? That can't be good for you. It probably blows your hair back like in those old maxell ads.

LOL, now THAT is some sweet ass overkill!!

I CAN get insane levels but I don't listen to my system at the extremes, it's fun to know it can! lol. Last time I checked, I can play my system well over reference in my room and the 4 x 21's and the 6 x 18's give out before the JTR's do

I'm thinking that a pair of T8s or T12s would sound sweet playing music through a old mellow 30 watt/ch tube amp. Has anyone tried anything like that?

Looks like the Triple 8/12 are overkill. How about producing a smaller version, ie Triple 6 ? I'm sure it'll fit the bill nicely.

I'd bet they would sell like hot cakes.

I had to get a second pair of Captivators for this reason. I don't have enough juice at home to run all 4 Caps and both T12s full tilt. The line voltage to the house sags so much it trips breakers. The T12s could still outgun out the quad Caps, depending on your taste in bass.

I have measured 120dB at 30 feet. Don't know how close I was to any limits.

In 1987 or 1988 I entered a car stereo "Crank It Up" contest at a local
event. Compared to everyone I knew my system was the best overall
sounding without a doubt. It was clear to me everyone else was competing
for 2nd thru 5th as I already had it won.
Long story short the judge and I jumped in my car he told me to "crank it up"
whipped out a SPL meter took the highest # and that was it. I won 3rd.
No one doubted that mine was the best sounding by far. So how could I get
3rd place. My best friend won 2nd Which was total BS. He stills rubs it in everytime
he comes to listen to my "home theater system". The contest was based on highest
SPL number and thats it, Distortion and all counted.
That is why I never pay attention to total SPL capability.
I have Never even measured mine because to me I truly do not want to find out.
I bought my T12's because they were rated at 1600watts @ 4ohm and that is alot.
I bought my D-SONIC M2 because in a perfect enviorment it can produce 1000w/ch @ 4ohm
and to me that is alot.

Big Speakers + Big Amp = Big Sound (Big SPL too)

I know that is "Simple Minded" but anything else is over my head or just confusing.
Remember I purchased 2 DefTech SC Reference subs because I read they could
go down to 11Hz.
Not at my house they can't. Not even close. Mabey they can but not me.

I am trying to learn. I read several members comments on several different threads even
when it does not apply to me just for the knowledge as I have ALOT to learn
This JTR thread is the easiest one for me to ask questions .
Thanks for all the explanations because I appreciate it.
I hope everyone is under the impression " no such thing as a dumb question"
since as time goes on I plan ON asking them anyway.
JTR owners have got me to wear I am now and
I Love It !!!
Thanks

A T6? Why? I Don't think that's going to happen since Jeff already has a smaller version of the T8. And there is no such thing as overkill.

I agree
Since it will still cost almost as much as the T8's and
more than the single 8's it would be a space or situation
issue.
If a theater room is to small for the T8's then it is probably
to small in general and T6'S can not fix that.
I know a few would be interesterd but since "most" people
are cost oriented it may or may not.
Just a question to see.
If Jeff had a T6 available for $999. would anyone be interested?
Now is a chance to peak Jeff's interest.
I truly do not know.
WVchris
And remember "There is no such thing as Overkill" !!!!

I thought Jeffs next project was already decided
QUINTUPLE 12'S Haha

So far so good. NIN beside me in time concert bluray is quite the experience with a little over 10,000 watts. Effortless and huge is the best way to describe it. The OS is in a league of it's own. My old twin 15" soundsplinters aren't bad subs but they certainly don't compare. I have to play with the positioning as I have a terrible suck out at 40Hz right now and it still sounds good. I have a lot of rattle proofing to do now too.

You do really have to be careful with the volume as there is no indication of how loud it is anymore. It's so clear and dynamic that I'm running 10dB higher than I ever used to and it doesn't sound as loud, until you turn it down and feel kinda deaf.

I don't think I ever got the shivers and goosebums with any of my old systems and I get them overtime i turn it on now.

Isn't that awesome?

Live music is wear it excells. It is hard to put into words what you
are Experiencing right now. I watched SLAYER this
morning from "The Big 4 Live From Sofia Bulgaria" Blu-Ray.
I did not know this level of sound was available till I got my system.
9 months later and I still cant describe this feeling in words.
Effortlesss with Endless Headroom
It just keeps getting better
Enjoy

Try ....Ten Years of godsmack the CD comes with a DVD
of an acoustical concert that is So Sweet on the 12's
and a mean bass guitar solo that would sound great on
the OS. My Subm HP'S love it.

I find myself looking around the basement or pausing the movie to make sure that there isn't someone upstairs or something going on in the house because sometimes, it freaks me out how real stuff can sound. Though sometimes the paranoid feeling has nothing to do with the sound

"Triple 12HT? Nope. That's a coaxial compression driver instead of the 12" coaxial. The horn is 60x40 degrees and rotatable."

Quoted from Jeff, the post was on the Facebook JTR page.

I want one ... well actually three.

Rob
Since your reviews and opinions have sold so many T12s
and JTR equipment in the past 3 years, I am sure
Jeff would look at it as a wise business decision to make you
" an offer you can't refuse" godfather style.
The sooner the better
WVchris

I would assume that can also be built in tower form with the horn on top.

Initial results with omnimic and minidsp. The raw response with the OS in my room wasn't great so I gave up on corner loading and ended up with it flipped around and almost in the middle of the side wall. That gave a relatively flat response from 30-100Hz. I had big peaks at 29 and 60Hz to cut and a null at 40 that took some boost. Not too concerned about the boost since the OS had the horsepower plus I have it high passed at 27Hz. My twin sealed 15's then pick up with a low pass at 27Hz and play flat to 6Hz where the built in 5Hz filter in the behringer ep4000 cuts in. This gves a nice house curve with neither sub really working all that hard. The OS takes the bulk of the content while the sealed ones take the load under the OS's tuning. I have one sub out on the 4311 y'd into both inputs on the minidsp so that the sub level on the receiver will shift the entire bass curve while I can use the gains on each system to tweak the curve itself. I have the mains crossed over at 80Hz which was the best result. The important part is it sounds fantastic! The bass is hugely powerful but clean and clear at the same time. I think the gain on the OS is at about 1/3 and the sub level at -1 on the 4311 which is 4dB hot. I did all the equalizing prior to running audessey which made almost no changes to the bass region but cleaned up the rest nicely.

Surprisingly there were no phase issues running the two types of subs together. If I messed with the delays in minidsp I could create some terrible cancellation but it was easy to avoid. Now I just need to figure out the null at 180Hz.

Very good looking response curve. Good to see that OM is reading that low for you, I dont seem to get much below about 10hz on mine but I have yet to send it back to get it fixed.

So, you'll be ordering 3 tomorrow then?

I already have

Great, looking forward to your impressions.

Just got some details on this new Triple 12 from JP. The first cabinet photos and drawings are for the Pro version with 10" drivers. These will utilize a new CD-Horn but with a 10" form factor. As pro audio speakers they are lighter and built for mobility (rough handling).

This one is a new Triple 12HT prototype with a new CD and horn. They will use essentially the same cabinet (vented and sealed) as the current T12's but have this new mid/HF CD-Horn and of course, a redesigned crossover. The CD and horn represent about as high end as one can/should practically go with these types of drivers and speaker design.

The question is, how much better will they sound and at what price?

The Bitter Sweet!!!
Will this new CD-horn completely replace the cuurrent T12's or
will it just be another option to the JTR arsenal?
Chris

I cant imagine it would replace the current. Both will have their intended applications: The CD/horn center for a constant directivity design, and the coaxial design for a broader soundstage. My main interest would be the ability to modify the current T-12HT with the new horn center and the appropriate XO. I would do this in a heartbeat, and take the leftover coaxial and just build out some single-12 height (or wide) speakers. Oh lord, I just thought of that, I might get on the horn with Jeff later today!!!

The problem with that is a square horn will not fit in a round hole.
Trying to cut it out myself could lead to a whole new set of problems.
Figuring the cost of the upgrade to the CD and crossover with the liability
of messing up an already great speaker leads me to believe just selling
the current T12's would be my only option.
I am not even considering that.
Now if RMK says it is worth it then Mabey.
thanks for reply
I hope the idea is to keep improving on our existing T12's like in the past.
Oh well its win win as long as I am not involved with a CNC machine
Chris

My understanding is that this is not a replacement for the current Triple 12HT. As noted, square peg/round hole makes upgrading the current cabinet difficult.

I think Jeff just wanted to take a shot at creating the best sounding HT speaker yet in his lineup. The CD is several times the cost of the current (already excellent) compression driver and the constant directivity advantages of the horn (as noted by beastaudio) should make this speaker more room friendly and improve the soundstage presentation while retaining the dynamic capability of the current model.

Not sure if these upgrades will interest the audiophiles but for those of us who are always looking for the last 5-10% of SQ it may be worthwhile. I would like to think that the speakers performance will determine if this is a winner but in this subjective world there are no guarantees.

I too can't imagine JTR moving completely away from the mid-tweeter coax. That would tend to put the speakers even more in the pro or HT category than they already are and would tend to move them further away from the "audiophile" category. I'd think there would be a risk of losing some of those folks who tend to straddle those two worlds. I'm one of those folks because my system is fully a 50-50 music-HT system and I'm not so sure that I'd choose a horn over the coax to cover the mids and highs.
