Looks like JL Audio just crashed the party on a lovefest with the typical brand subs. These new developements will send a lot of people back to the drawing board. Great news for the consumer!
Some people have been saying it for a long time (Sealed, small, long throw, big power), mostly falling on deaf ears
. Good to see a manufacturer finally putting it to good use.
Can Craig's outdoor numbers of the F113 be compared in anyway to the subs in The Way Down Deep test?
Unfortunately, we only have 10%(ish) THD limited output numbers at 3 frequencies (16, 20 & 25Hz), and Yates doesn't limit THD. He uses the compression test and records the THD as the compression graphs reach their limit.
The only 10% limited comparo with an SVS 2X12" is Ed's numbers on the Ultra 2, which, as Ilk has pointed out to me, should be within .5-1.0dB of the Plus 2.
Craig's F113 #s: Ed's Ultra 2 #s:
16Hz: 93.7dB 18Hz: 100.7dB
20Hz: 100.2dB 20Hz: 102.8dB
25Hz 109.8dB 25Hz: 106dB
All of Ed's numbers are amp limited, so I would say that the Fathom would have more gas in the tank at less objectionable consequences than the SV subs.
Of course, the size of the Fathom's box, in relation to the driver's capabilities, allow for excursion headroom and big power to be applied where the opposite is true of the bigger ported sub. Nothing new here. Just took JL to realize it and build one (or 3) subs
