Official JTR Orbit Shifter Subwoofer Thread

post #1 of 1182
Thread Starter 
Here is a Post By Jeff Permanian on the JTR Forum site:

Quote:


The Orbit Shifter LF is currently in development and should be available by mid June. The first are to be displayed in public June 12th.



100db 1w (103db 2.83V) outdoors, ground plane, 1 meter

25-150hz +/-3db outdoors, ground plane

30" tall, 22.5" wide, 45" deep (mouth 30" x 22.5" side)

160 lbs



Uses the same amplifier as the Duo, 4000 watts RMS and 7200 watts burst peak. "Low" mode will adjust the subwoofer for flat response down to 20hz.



Output Capablility: (calculated from 4000w, not 7200w peak)

133db average above 25hz, outdoors, ground plane, 1 meter

120db at 20hz, outdoors, ground plane, 1 meter

103db at 10hz, outdoors, ground plane, 1 meter

145db average above 25hz, eighth space (corner loaded), 1 meter

132db at 20hz, outdoors, eighth space (corner loaded), 1 meter

115db at 10hz, outdoors, eighth space (corner loaded), 1 meter

In room numbers will be even higher than the eighth space (corner loaded) calculations.


For best results from two Orbit Shifters, install them along a wall either facing corners of a room, facing each other or, one of each depending on room modes.


Retail - $3599
Direct - $3199
-5% - $3039 (+4)
-10% - $2879 (+8)

The mentioned June 12th (Saturday) initial public demo will be in my HT in California. A pair of Orbit Shifters will be replacing my dual Captivators and all interested parties are welcome to attend. I will be posting a Thread with details in the Area Home Theater Meets Section of the Forum.

Should be interesting ...

Wow! It looks to be the most powerful commercial sub ever.
post #3 of 1182
This looks to have a low end similar of the DTS-10 and midbass of the cinemonster. Great combo!!!!

Amp wise I believe you are correct.

I hope so of course, "the proof is in the pudding".

I am sure it will be great. Everything Jeff makes is great. That is pretty small for so much low end output. I believe the DTS-10 is 90db's at 12 hz ground plane with 1 watt. So 2000 watts takes it very high. They are very big for low end output.

I'm not just talking about amp output, but overall SPL output as well.

Man Jeff is not playin!

Sounds awesome!

Looking forward to your impressions RMK!

Are you sure you don't want 4?

Yeah, but that 8 price is pretty attractive .

I'm guessing it's a 25hz knee FLH using a TC Sounds driver or drivers.

Clash of the Titans:
Orbit Shifter vs. Terraform XL vs. Danley DTS-10.

Now that would be a back-breaker of a shootout!

Lets do a group buy =)

I have been saying this for a while now, if you want the most accurate and dynamic theater experience from a commercial company these are the 3 companies to choose from.

What is the biggest difference between this and the recently announced Growler Duo?

These seem like niche products for the truly obsessed and then the professional audience.

Models change mid-stream. They all have fairly extreme output, but then they are sized accordingly.

Let me know if Art Sonneborn swaps out his 3 Submersives for anything new.

I thought he had 4.

4000Wrms? But isn't the limit from my typical 120V 15A AC line about 1800Wrms based on a 100% efficient amp?

Well yes that's true and 4K amps do seem like overkill.

I have a couple of 20 amp circuits available in the HT room and they will provide 2200 watts each. Despite the headroom these very powerful amps provide, I do not want to reduce my house to a pile of rubble so I won't be tripping any breakers .

How many or what kind of drivers The Orbit Shifter LF will be useing (10-inch, 12-inch, 15-inch....????), and how long the horn path will be ?? the box is quite big. Wondering if the ampl will be also 220/230 V ready!

My guess is double 12" or a little bit less likely an 18".

18"

That would be a weird setup for a horn then based on the dimensions he gave or the horn length is really short. For an 18" driver a tapered horn would need a massive horn length and a box that is probably twice the size that what jeff is listing.


But hey I could be wrong
post #25 of 1182
Could be wrong but I don't think it's tapped. All of the previous horn offerings have been FLH.

As was suggested earlier, a comparison to your DTS-10 pair and Fugueness's Terraform XL's would be fun. Maybe Peter has a connection and we could use the Greek Theater .

How is this design capable of these enormous numbers if the amp in only puuting out half of the stated power numbers based on the limits of a circuit. Jeff calculated everything of the 4000Watt estimate but if the amp is limited to just half, then those numbers are not realistic, is this correct or am I missing something?

I can prove the stated amp power and Orbit Shifter LF subwoofer numbers here in EU we have 230V, 20A which is enough for 4600W

Did you see the YouTube video of the Triple 8/Growler Duo? Same 4K amp that is used in the OS running on a long 12 gauge extension cord off of a 120V service. Was that loud enough for you?

Those numbers are off the charts crazy for most rooms. The point is that if you provide the current they can get there. Why anyone would want to is another question.

Now if you have 20,000^3, maybe ...
