Hey Mark,
I was over friends house last night and he's was talking about getting a new sub. He was talking about a 113 and I of course was pushing the Submersive. He's coming over in the next few days to hear mone. Can you give me a comparison between the two? He still hasn't seen or heard the Submersive so I'm hoping I can convince him.
Thanks,
Joe

A while ago, when I was still looking I asked Mark the same thing:
Here is my question
There is allot of buzz about the new JL audio subs. They seem on face value to be pretty good. 121db. Down to 19Hz ground plane.
Here was Marks reply
121dB is simply a maximum output at 1m. This doesn't tell you anything regarding the maximum output at 20Hz or what sort of compression will be seen at that point. The SubMersive easily does maximum levels of 122-125dB above 40Hz. The performance of the SubMersive should basically be close or edge out that of the f113 in maximum capability terms, but the SubMersive does it with much less power and great efficiency. This translates to less compression and less issues with pushing the drivers to their physical limits under 95% of operating conditions. The f113 and f213 will be very good products, but take very expensive, brute force means to achieve their results. The mechanically stable design of the SubMersive still trumps the most exotic of box constructions, and while everyone likes to boast about huge power amps, in many homes the wall Voltage sags before you can deliver that output.
Also, he said
I did note that JL send Ilkka some measurements of the F113, and from what I see, the SubMersive is about equal down low, probably with more very low frequency extension, and has more headroom and dynamic linearity above 40Hz.
So that might get you started on how to compare the two.  Hopefully Mark can come in and qualify it even better then this
P.S, I hope Mark does not mind me posting this stuff.  I would hate to make him upset
I simply love this stuff.

One thing you can say for sure is that the Submersive's pair of drivers should be able to displace a lot of air with a lot less effort than the f113 driver.

Hi Joe,

Mike and mojomike's posts covered the basics.  The long story short is that the SubMersive is significantly more efficient to do its thing with 1000W vs. the JL with 2500W, and really only gives up ground in the aesthetic and size for a significantly lower price.  I will be curious to see some more of Ilkka's testing which will shed some more light on exactly what the F113 is doing, particularly in its frequency response.  The SubMersive has some real strengths in the upper bass dynamics and headroom, which is where much of that slam and impact lives.  The SubMersive is also very smooth through the upper frequency range.  Reports I've heard have indicated that the JL subs do high pass in the mid teens, so you won't get the extended VLF coupling that everyone has observed with the SubMersive.  I do feel all of this adds up to an audible difference, and IMO, an advantage.

Thanks Mark!  I'll try and get him this weekend, he's coming over Sunday so we'll see if I can impress. I should have bought two though
