OK, I'll start this one. MY new 212HT LCR's should ship this week and so I may have them by next weekend. Jeff is busy building and shipping so i don't expect him to post much here but some pictures would be nice.

I have a couple pics of the 212HT-LP's but can't post them here so ...

Will post my impressions relative to the Triple 12-HT's once I get them an spend some time with familiar source material (music and movies) and I hope others will do the same.

I think I get to demo these in my theater for the weekend after Desertdome brings them over.  Excited to hear them.

That is very cool H/O. I think it is smart of Jeff to allow a pair to be sent around for in-home demo's at certain qualified HT enthusiasts homes. They are commercial grade construction and so damage is unlikely and maybe someone will buy the demo pair (at a slight discount )

Jeff-hope that was okay to play these for the weekend!

I need to adjust something in J River because I was getting feedback a tiny bit after I went phantom center and adjusted down the level some -10db to match the sensitivity (up from my SHO-10s).  

I feel for these speakers, I'm only giving them AVR juice.  I could always hook my clone up to them and go 2 channel but that's probably just asking for it-they don't need more than what I'm giving them already.

Played Halo 4 xbox game on them for about 1.5 hours.  Sounds beautiful.  Clear as I've heard anything in my theater and maybe around town here.  I wish I had treatments for these as at volume I get a bit more fatigued but I'm sure some of that is my levels (desertdome still has my SPL meter so I'm not matched perfectly).

I need to lower my crossover to 60hz from the current 100hz and play some music and go through the first 20 min of Art of Flight again.

These pair well with my Quad UXLs though.   Sounds good so far.

I can just imagine what some Cap Pros and these outdoors would sound like!

More later.

I took the demo Noesis pair back to Jonathan a couple of days ago.  I'm already going through withdrawals.  I of course hooked my eD cinema speakers back up, and it's just not doing it for me.  They sound thin, and really lack the mid-bass that the Noesis pump out.

The highs are good, but sound grainy/scratchy compared to the smooth sound of the Noesis.  

I got to the point with the Noesis that I was crossing them over at 80hz, even for music and for the first time EVER running the subs flat with the speakers and the sound was fantastic.

Now that I'm back to the eD's I had to go back to the 150hz crossover for music and running the subs hot again.  It doesn't sound near as clear, it's muddied up a bit, but it's preferrable to the thin sound of running the subs flat and having a lower crossover.

The thing is, I thought I was completely happy with the eD's before I heard the Noesis.  I'm going to have to be careful in the future, I'm not going to demo a pair of speakers unless I plan on the possibility that I might buy them.  I had no plans whatsoever of buying the Noesis.

I'm looking forward to next week, Jeff says I'll get them before that weekend.  Can't wait.

You know, the the opposite might end up being true in that demo's will only re-affirm your satisfaction with the Noesis. But under the circumstances, I understand your trepidation ...

Here are a series of posts from AVS by myself and a good guy from Minnesota who was out my way on business and wanted to hear the Noesis and Orbit Shifters. A friend of mine was also there and it was really fun having guys in the HT who really get what it is and who enjoy letting the system get really loud :-)


I hope Lukeamdman doesn't mind my posting this here but I thought it would be good to revive this thread based upon this quick review by an avid DIY'er. There have been several disparaging comments from the DIY "bubble" about the Orbit Shifters and all of them have been anecdotal or based upon a misinterpretation this one posted graph ^.

I would like Jeff to send an OS to Josh for testing but that is a big deal and not an inexpensive proposition for Jeff. These subs are what they are (profound no ) and having heard many alternatives they remain my favorite option. It was good to have someone with quad sealed LMS 5400 powered by uber amps give his honest and unbiased take and I'd like to extend my thanks to Luke for doing so ...

There were two things I wanted to hear, and both happen to be JTR products… The Triple12, and the OS. It just so happens, he recently sold the T12s and has bran new Neosis for LCR. Even better!
First off, his theater room is awesome. Aesthetically pleasing, spacious, great acoustics after what he’s done to it, and the AT screen is just beautiful. My theater room, called “the dungeon”, or “the scary room” by my wife, looks even worse now, and that shouldn’t be possible. Thanks a lot, Rob…
Anyway, on to my impressions, and I think Jeff did a fantastic job with the Neosis. I’ve been dabbling in the DIY world, most recently working on building crossovers, and for the 12s in the Neosis to blend in as well and they do with the CD, Jeff is really doing a quality job with that crossover. Just amazing. I don’t want to guess as to how many hours he put into R&D for the crossover for this speaker! Highs were crisp and clean, not harsh, and the mids blended seamlessly and were very detailed. At several points in the demo Rob exceeded +5db in the main volume, and Neosis didn’t even blink. Never sounded strained or distorted ever.
As for the bass, I feel I’ve heard the best of what’s out there, and I wasn’t expecting to being impressed by two 18s, regardless of their configuration. I was definitely wrong! For starters, the obit shifters are HUGE. Pictures don’t paint the whole picture here. Second, having never heard a horn loaded sub before, they do have a “unique” sound to them, and I’m saying that in a completely positive way. Great punch, great detail, and great sub 20hz response and tactile feel. I know for a fact that at certain points in the demo the orbit shifters exceeded 125db, and they did so effortlessly. Considering I have quad LMS 5400s and 16kw worth of power feeding them, I didn’t expect two 18s and half the power to accomplish what they did. I may have to build four “gjallarhorn” enclosures for my 5400s now
Thanks for the demo, Rob!

And, this post in the DIY Section:

A trip over to RMK’s place a couple days ago got the wheels turning. Long story short, two JTR Orbit Shifters, which combined is two 18” drivers and 8kw of power, gave my quad 18’s and 16kw of power a run for their money! To be more specific, I feel his setup had greater output above 30hz, and mine had greater output from the mid 20’s on down.

The efficiency of the horn design definitely impressed me, so I started to look around. It didn’t take me long to find the GJALLARGORN on Ricci’s data-bass.com. From his measurements, just one gjallarhorn will outperform all four of my sealed 5400s from 16-40hz-ish, and obviously with far less power.

The plan is two build two of these, and re-use two of the 5400s from one of my sealed cabinets. That means I’ll still have two other sealed 5400s powered by a LG clone, which can help cover the top 60-80hz portion where the gjallarhorn may need some help. The only investment for me is the cost of the wood.

Ricci already emailed me the detailed plans, so all I have to do is find 4x8 sheets of quality Baltic birch and I’ll get started<img src="/images/boards/smilies/smile.gif" border="0" align="absmiddle">

Point of this being that hearing the OS's prompted this fellow to want to build a couple of Horn based subs using two of his super drivers that are currently installed in a sealed cabinet he built. I admire his abilities and understand Luke's priorities. For some of us, just buying something that performs at the level of the OS's is the best course. In any case, this just provides a bit more information for someone looking for a sub like the OS.

carp you suck.

After saturday night's demo session at your house I was playing with your former eD speakers at my house and feeling the same way about the highs.  The Noesis clean sweep the eD's in every sense of the phrase, and before I heard the Noesis - I too really liked your eD speakers.   I still like them --- but the Noesis are absolutely a cut above.

I know why, because the JTR is using BMS drivers  one of the best on the market for the money, you will find those drivers in many Hi-Fi top end speakers and I am using in my mid/hi horns BMS too.

ZivkoF, That isn't entirely true. A speakers is a system of many parts that all have to work together.  The crossover, cabinet, horn and woofers are all very important parts that have been carefully designed.

Hi Jeff,

yes I know that the driver is only a part of the successful JTR story, the main task is the correct assembly of other parts designed to work together.
