I haven't a clue but I would have thought your room would not have a huge negative affect on 13hz and lower but maybe I am wrong?

Any more listening impressions?


Compared to your captivator setup are you impressed with the new system enough to justify the extra expense of these 1k drivers?

- Wow these drivers in a sealed box are power hungry


- WOW the FP14000 is powerful!!!


- Wow the 5400 + VMP design is much more efficient


- Wow this thing sounds good



At first it sounded good, but not great. The punch and weight of the bass was missing, and it didn't play well with the VMP sub AT ALL. Both sounded much better playing by themselves. I inverted the polarity on the MiniDSP for the sealed sub and bingoDANG it sounds good!


I can see how a Marathon MA-5050 would come in a little short for powering one of these. The FP14000 seems endless for power. It just keep going and going, and my ears say stop when trying to find its limits. I haven't seen the clip lights yet, and for me that's a first.


The cost of these two weren't too far apart. The dual sealed setup was about $150 more expensive, but theFP14000 was 3x the cost of an EP4000.

As I get some time to listen, and for the new drivers to break in, I'll post some thoughts on the sound differences between the two. Even at this point with only a couple minutes of listening, I prefer the sealed setup.

how do you invert the polarity on the MiniDSP?

Inverting MDSP:


Click on "Delay/Gain/RMS-outputs 1 & 2" (Or outputs 3 & 4, whichever you are trying to invert)


On bottom right corner of output channels is the button to click on. If it is glowing green it is inverted.

Very interested in your impressions here as well as I LOVE my JTR t-12's and can imagine the caps are just as high quality of a build as they are

This setup is almost twice the cost as my dual Cap setup, but it is a improvement in every way.


Earlier this year when I was looking to upgrade from my DD-18, I wanted more low end output but didn't want to lose the clean and crisp punch of the DD-18.


A single Cap had the output down to 20hz, easily more than two DD-18's were capable of, but the bass reflex design wasn't as clean down low. There was also the inherent problem with bass reflex designs which is port noise. Even without the the Peavey 4080hz, a EP4000 could drive a Cap hard enough to produce port noise. I will say this though, it was the least noticeable amount of port noise I've ever experienced with a ported sub.


Because of the cost between the two setups, it's not really a fair comparison. The quad 5400s are cleaner, louder, and play much much much lower. At 40hz and up I had no issue with the Caps, but when we're talking about 10hz to 25hz performance, there's no comparison, and considering the price difference there really shouldn't be.


This to me is really the best of all worlds. Bass that extends to 10hz and below depending on the room, a crisp and powerful punch at 50-60hz, ultra low distortion, zero port noise, and with the FP14000's they have what seems like limitless output.

Overall do you think this is more a product of the rediculous amounts of power you have going to the LMS's vs the caps, or more the specific design? Obviously sealed will go lower, but further up in the passband?

The sealed design obviously eliminates any port noise, and that's a major annoyance of mine. Also, according to my ears, sealed subs play clearer/cleaner for sub 30hz material.


The ridiculous amount of power is kind of necessary considering how inefficient these drivers are when sealed. However, the FP14000 just happens to be ridiculous enough to even over-power TWO of these drivers at once. I'm sure something like the QSC RMX 5050 and Marathon MA-5050 could push these loud, but probably not as loud as dual Caps with a EP4000...

Are those in phase? might just be the angle/video but they looked out of phase.

They're in phase. I'm not sure why they look like that in the video but I noticed the same thing.

Please post more videos of your quad sealed LMS 5400 ultra 18" subs powered by dual FP14000s on some bass-heavy scenes or musics
btw, where did you hide your FP14000s
