Wow, can't get over how much mid bass that OS pro has.  It's not like it doesn't have any low bass (not LFE obviously), hell it matches a G Horn at 32 hz, which also matches the sealed SI 24 at 32 hz. 

 

With music this thing must be able to beat the living crap out of your chest.  I was impressed with the Growler but this thing beats it by 10 db's.  I was thinking that someday I'd have to pay someone to build me an Othorn, but it looks like there is no need with this beast available.  

 

I was actually thinking about buying the OS Pro before I built the Othorns.  However, after the shipping cost of the OS Pro was taken into account, I could build two Othorns for the price of a single OS Pro.

 

If you get a couple OS Pro's, you better not power them with a weak sauce amp like a CV-5K or iNuke/IPR in stereo or something lame.  That would be a crime to what they're capable of!

Ha, no can't get one anytime soon but when I do I'll be sure to get the right amp.

My current amps do the job since the SI drivers don't need a lot of power.

Enjoying the positive comments about the JTR range. I'm a bit older now but I'm still crazy enough to want that Pro Orbit Shifter hmmmm someday.........

The Captivator 1400 is completely redesigned for 2017:

New driver with 33mm Xmax for lower distortion and increased output.
New larger port for increased bottomend (+9% more port area than triple 3.5" diameter ports)
New cabinet with improved bracing and damping for lower distortion and better sound quality.
New dsp program with improved "LF adjust" that simulates a sealed sub roll off when turned all the way down.
The new Captivator 1400 outputs over 1db more on the bottomend and will hopefully be tested by Data-Bass in the spring.

Same old price!

Hello Jeff, can you tell us a little bit about the driver differences between this new cap 1400 and the current version?

The new has the same geometry as the Captivator 4000ulf drivers(different impedance for the 1400w amp).

We're really excited about the new Captivator 118HT. We're measuring the same output as the 1400 from 50hz and up while still putting out 105db at 16hz, 2m, rms. Hopefully, Josh can test the 118, 1400 and S1 in the spring.

How was that 10th anniversary party? Sorry I couldn't make it.

It was good. People actually came in from NH, FL, NE and other places. We showed off a pair of Captivator 4000ULF is the warehouse and then new Captivator 118HT in the demo room.

Yes sir. The celphone audio is horrible so just ignore that.

Jeff, could you chime in about how the driver is able to put out more low end with the same amount of power? The bigger ports mean there is less enclosure volume, so the power requirement should go up, but the old Cap 1400 is already pretty severely power limited. The other way is more motor strength, but the old driver is already very high.

We modified the cabinet to regain the cabinet volume. With the new driver we had to lower the dcr a little to get the efficiency back that was lost from the longer coil. The, in band, zmin is exactly 2.5 ohms which is the minimum the 700asc module will put out full power.

Jeff, does the cap driver use round or flat wire?

For 2017, we increased the Orbit Shifter and Captivator 1400 driver's Xmas to 33mm (from 30mm).

Can I ask what's the big deal with round or flat wires? Using round or flat wires make a performance difference? I would think the question I asked about how the Cap is getting more low end output would be a way bigger secret than the type of wire used. I'm not pressuring Jeff to divulge in any way, I'm just wondering how the type of wire could be more secretive than getting more low end output from an already exceptionally optimized system.

Showing off dyno charts is one thing but that isn't going to tell anyone how they got those numbers. Popping the hood of a car isn't going to show the cam profile, compression, squish, rod length, fuel map, etc. We don't discuss magnets and steel grades, motor geometry or voicecoil specs. Someone can pull a driver out and get t/s parameters but they won't know how we got there.

Sure I understand, the flat (or edge wound) coils (at least from precision econowind) cam really do a number to the part cost. I have typically seen about 8-10% higher L numbers as a result. This of course will raise inductance too, but the advantage here is you don't need to make the gap wider and hurt the B as would be the case with another layer or two of turns to achieve similar results.
 
Flat seems to be an advantage, but its not night and day and doesn't dictate final performance as Jeff mentioned.
