Well, we had a small GTG at Chucky7's house yesterday (@Chucky7,
, and myself). The JTR Cap1400 and the PSA S3000i. To cut to the chase, there was no winner in my mind, only that the two subs have inherent differences. Neither sounded better to me overall, just different.
Chucky runs his LFE +10dB hot & we also ran the volume well over reference. His room is not large and had considerable room gain despite two openings leading to the kitchen and the rest of the house. We ran clips from the Ultimate Bass Demo Discs as well as some music (Hotel California in 5.1 DTS HD MA sounded great). The JTR had in-room extension to about 14Hz and hit peaks of 125 dB between 20-30Hz w/movie clips. The PSA was no slouch with extension down to 6Hz and hitting peaks of 120dB from 20-30Hz.
We moved the JTR to the other front ¼ wall position for better FR and placed the PSA in its original place.
At the levels we were playing (~10dB over reference) there was definitely some chuffing on the JTR but it didn't bother me because it had an amazing ability to create wind! Not just a small breeze but strong wind if you were directly in front of the port. We sat about 2m from the front of the JTR. The JTR was also more tactile (except for at 10Hz of course) for the most part. The PSA had a bit more mid-bass.
seemed no closer to making a decision when we left than before. A Cap2400 will hit 20Hz but he can't face it towards the MLP to feel the wind. At regular listening volumes I doubt the chuffing is a big issue. A second Cap1400 would likely increase chuff free headroom.
Honestly, without the sealed S3000i there and REW RTA we wouldn't know we were missing any content at 10Hz.
Is there something about the Cap1400 that produces more port wind than other designs?
I personally think the new
FV25 should be a consideration for the OP to get a form factor closer to the Cap1400 and also get 10Hz extension. It should be quite formidable in his size room with room gain.
Because I am a champion of dual subs I believe dual PSA V1801s have a great price, finish, and form factor and would be a better choice than a single Cap1400 for the OP (giving up on the quest for 10Hz). But oh the Cap1400 wind!
