I am selling my dual OS LF's and I would like to do it locally to avoid shipping. These units were the first Orbit Shifters delivered to AVS user RMK in 2010. I bought them from a friend of his earlier this year. They are the first design with the mouth of the horn exiting on the end. The LFU version that I bought later has the mouth of the horn exiting from the side. I still have my old LFU and I am going to try to find a match for it. The space behind my false wall is very tight and my room is not very wide. So the upright version gives me more placement options. Other than that I am extremely happy with the product and my plan is to stay with an Orbit Shifter for bass reproduction as long as I can find a unit that was made before Jeff changed the design again to the current units.
calibrated these subs and noticed that one of the amps had a different DSP programmed into it and was making a whirring sound intermittently. I removed both amps and sent them to Speaker Power to have them looked at and both reprogrammed for the appropriate DSP. They are functioning perfectly now. They are very hight quality amps rated for 4000 watt RMS and 7200 watt peaks and Jeff does a great job of taking care of his customers.
I think the buyer should get both of them from me because the OS really benefits from having duals and you will get a much smoother response. One is probably plenty for most people in the frequencies that really matter but the overall response will be smoother with 2.
The output is pretty insane. When compared with the new Captivator 4000 ULF they almost tie at 25 and 31.5 Hz. Then at 40, 50, 63, and 80 the Orbit Shifter bests the 4000 ULF. And if you are worried about the low end then the 16 Hz output is still 101.5 db so there is plenty to work with. If you care more about single digit performance then there are other units better suited.
Here is the link to a chart put together from Data-Bass and a few other sources that demonstrates the output. https://www.avsforum.com/forum/attach...5&d=1494018983
And here is the test from Data-Bass. The LFU design is very similar to the LF design and should not deviate substantially. I confirmed this with Jeff over the phone before I made the purchase. http://www.data-bass.com/data?page=system&id=123
This is the link to the original post in the JTR forum made by Jeff about the new horn design. The pictures have expired thanks to photo bucket. https://jtrspeakers.websitetoolbox.c...ter-lf-4700464
If you have the room for these subs and are willing to slide them around till you get the perfect response I think you will be very happy. I am only 6-12'' from perfect placement but just can't quite make it work. If you want to demo over at my place then feel free. Even less than perfect placement these subs sound fantastic and can absolutely destroy my foundation. Maybe I should have a movie night for those interested. I am not in a huge hurry to sell but I wanted to put it out there for local guys first. Then after a bit I will make an official for sale thread in the classifieds. Most likely the classified thread will be for $3000 plus an additional $250 for shipping. That is close what I paid to have them shipped here.
The best thing about these subs is truly the sound quality. It is more special than the output in my opinion.
And you will not need butt kickers with these. Or a near field. Just think of the savings! Ha!
