I only know of a handful of movies with sub 20hz content, certainly not enough to tune a sub to those frequencies. Anyone shed any light on this? Is there another reason?
I wouldn't say the Cap 1400 is a better design. It is definitely more mainstream. It is JTR's first active sub tuned to 17Hz and priced under $2000 plus shipping.
BEQ actually became popular after LT ported became more common.
Back in the days, if your goal is reference capable down to single digits, your only choice would be multiple sealed subs. The bigger the room, the more you need. However, 2 sealed subs just don't provide the same amount of TR from 2 ported. A 17Hz tuned ported certainly is more efficient from 16~40Hz. Below the port tune, its output drops like a cliff.
JTR's design philosophy is always about filling a niche. Jeff saw a market for 10Hz tuned ported subs so he created the Cap 4000ULF. The 2400ULF was the 4000ULF scaled down. The 2400 was the 1400 tuned to 10Hz.
I believe Jeff decided to lower the 1400's 17Hz port tune to the 2400's 10Hz because there are a lot of competition in <$2000 market. The Cap 1400 was selling for $2199 + shipping. Therefore, for $300 more ( and $2,200 now shipped!!!
), bassheads can get a Cap 2400 that covers down to 10Hz and is much more efficient than a sealed around port tune. With 2 of them, most rooms can be 110dB capable down to 10Hz.
Further, there is sonic advantage. Though JTR excels at clamping down the port noise while maximizing the port wind, the 17Hz tuned Cap 1400 is not immune to chuffing from movies with super hot content at ~20Hz, which are much more common than those with super hot content at single digits.
The 10Hz tuned Cap 2400 also creates enough product differentiation because most people would go for the Cap 1400 (@$2199) rather than the Cap 118HT ($1699).
