REW lets you see what you are hearing. Even moving the sub a few inches can make a big difference relative to the MLP and REW lets you see it and address. Alternatively you can do a sub crawl but with a sub that size, it ain’t going to be pretty....

I'm looking at the 1400 or 2400. I had a couple of questions for JTR. How long does it usually take for JTR to respond back?
It can take awhile. Jeff is the builder, customer service and sales so he is a busy man. I have an order in and had asked him a question last Monday with no response. Just be patient and he will get back to you and if you buy anything JTR you will realize it was worth the wait.

Okay then. Guess I need to start researching REW and figuring out how to use it and understand the graphs and all that good stuff.

I would start with purchasing a UMIK-1 mic from minidsp, Amazon or CSL labs and a laptop with a HDMI connection. There is a separate thread for REW at

https://www.avsforum.com/forum/91-aud...et-graphs.html

Download the guide complied by Austin Jerry. Its a great place to start. Its linked in his signature in the above thread.

Did you ask a question via email to [email protected] or [email protected]?

Based on my experience, Jeff usually responds within a business day. However, make sure you check your junk mail. I would say that if you emailed [email protected] or [email protected] and did not get a reply after 2 business days, you should try to contact him with other methods -- PM or calling 847-714-6878.

Excellent point @torii . This is a lot to absorb and it can get overwhelming. As tori said, get your subs set up and dialed in by ear and whatever EQ your AVR has. Listen to them for a while, let them break in a bit. Get a feel for what they can do, what you like (most everything) and what may be not sounding just right. Play with the LF Adjust setting. Another words, Don't get caught up in REW just now. Wait a few weeks, months. I waited and it made it easy. Test drive the car before you put it on a Dyno and run new performance programs.

Like I said in the beginning. Go slow. Spend as much time as you can listening to Music/Movies you know and have a good sense for. Get to know the subs is always best before breaking out REW. In the end, to squeeze out the best room FR you will need REW or OmniMic to help you see what the subs are doing in regards to standing waves, nulls, peaks.

In the beginning, just have fun and plug and play! Let the Bass move you. And anything and damn near everything in your house. Go buy those little felt stick on things in bulk. Your going to need them. I spent weeks, no scratch that. Months, chasing down rattles. Getting that fixed is priority #1 and you don't need REW for that.

Enjoy your new Subs.

Hello everyone,

I have been contemplating about JTR subs for a long time (about 4 years more or less) Having only owned sealed for many years, I have always wonfdered about JTR ported subs. Yesterday I ordered 3 Cap 2400ULF Tall. My room is 21 x 11 x 9 which I believe puts me at 2079 ft^3

I'm anxious for the 2 week lead time and Jeff has nothing but responsive. Every time I called, Jeff has picked up the phone and was very friendly and helpful.

BTW, I did much research and looked at 2 Cap 4000ULF for my room. @Marc Alexander suggested I might kill myself in that small of a room with those big behemoths.. lol seriously though... 3 2400s in my sealed room is going to be pretty crazy, I can't imagine what 2 Cap4000 would be like. I guess in the future I can always add one more Cap 2400 and it would be like having 2 C4Ks...

Anyway here is another link to the other thread that I started

https://www.avsforum.com/forum/113-su...l#post55625882

I went as far as contemplating DIY but after much research, I found that JTR subs have so much value and positives that it made sense for me to go this route.

I hope to have more to report in 2 or 3 weeks once I receive these bad boys and placing them in my theater.

At that pricepoint w/ the 3 subs, i would have bit the bullet and just went w/ the dual 4000s (less money to boot). You will always have the what-ifs. The dual 4k will easily get you in the mid single digits where the trip 2400s will not.

Goodness and congrats!!

The bass in your room won't be "pretty crazy," it would be off-the-chart crazy :-), but if you're a nutty basshead (a compliment), then you're a nutty basshead LOL. Plus there is that level knob that you could turn down.

FWIW, that was one of my reasons for going with JTR: I needed to know what this amount of bass power in a ported design sounds like in my room. Now that I have it, there's no going back, even with my humble - but very very pretty :-) - 1400.

You probably have plenty of time to change your mind if you were considering a change like suggested by Junkie.

Jeff just sent me an email an hour ago about the two 2400's I ordered a couple weeks ago. He said the driver manufacturer had some supply chain issues that is causing a delay. The manufacturer said they are okay now and are assembling the drivers as we speak. They expect to ship the drivers to Jeff next Wednesday and Jeff expects them to bee deliverd on the following Monday or Tuesday.

I ordered Hacksaw Ridge and Interstellar to watch with my new subs. Dark Night and Master and Commander were great on my submersives so I will also be interested to listen to the differences in those movies.

Damnit I need to stay away from this avs forum lol

I want 2 cap4Ks but @Marc Alexander came over and he said the size alone on those bad boys would be a disadvantage because I loose the flexibility.

If you look at the link I posted, I think I attached pictures in the earlier postings.

I could accommodate two 4K LP at the back and maybe one regular one up front and one at the back.

When Marc did measurements he said that the best room placement for my room was opposite sides in each corner from each far end.. so think X placement in a rectangular room length wise not width

**** you got me rethinking man.. lol

You will always have the what-if birdie on your shoulder now, LOL. There is absolute no disadvantage to dual 4ks from 3 2400s.

8000 watts vs 7200 watts
4x 18" drivers vs 3x 18" drivers
Tuned to 10hz vs 14hz

NO, because you would need awhole lot of 2400s to match dual 4ks in the 10hz and lower frequency. You would need 2x 2400s to match the 10 hz freq. of the cap 4000.

Dual Cap 4k at 10 hz: 114db
4 Cap 2400 at 10hz: 109-110db (2 subs add 6db, 3 sub adds 3db, 4 subs add 2-1 db.)

**Would take almost 6x Cap 2400s to match the 10 hz range of 2x Cap 4000s. Let that sink in.

Regardless of which one you go with, if you can’t place them right don’t matter if you have 15 18 inchers with 15,000 Watts. So let that be a determining factor. If 2400 give you more placement flexibility then go with that. If placement options are identical then go with the 4000.

Looking at initial considerations for building a dedicated home theater. I’m currently using a media room which serves me really well, but the wife is hating the Cap 4000 for moderate and above listening levels. I love the deep smooth bass, but it does shake the house too much for her especially late into the evening.

The wife has allocated the resources for me to move my system and build a sound isolated dedicated theater in a 20x20 room to keep her and myself happy. My budget is robust so I’m not sweating the finances.

I’ve had one initial consultation with an acoustic design firm. I was moderately disappointed with their mentality of we build what we want and you will like it. It almost felt like they’ve figured out one good system and they believe if the shoe fits..

Where our conversation went astray was in the subwoofer department. They told me two Procella 18” dual sealed subs would clearly impress me and I’d want to sell my Cap 4000. I told them I wanted two Cap 4000s in the room. Then I looked at the skinny sealed mini box that looked like it was built for the back of a Ford Ranger. They want these little boxes to save space behind my screen. They are 12” deep so they believe I can produce serious impactful bass from 4 sealed 18” woofers in a mini box after I’ve been using a nearfield Cap 4000.

I’m not obviously sold on this company, but I just wanted to hear if anyone had experience with Procella subs and if they feel in a 20x20x12 ft room I’d be happy.

That is what Marc said.. I?m going to measure again to see if I can do 2 x 4K

Will update you guys

I?m also going to take pictures

And maybe place tape to show where the boxes will be placed

I want 2 cap4Ks but @Marc Alexander came over and he said the size alone on those bad boys would be a disadvantage because I loose the flexibility.

If you look at the link I posted, I think I attached pictures in the earlier postings.

I could accommodate two 4K LP at the back and maybe one regular one up front and one at the back.

When Marc did measurements he said that the best room placement for my room was opposite sides in each corner from each far end.. so think X placement in a rectangular room length wise not width

**** you got me rethinking man.. lol


Regardless of which one you go with, if you can?t place them right don?t matter if you have 15 18 inchers with 15,000 Watts. So let that be a determining factor. If 2400 give you more placement flexibility then go with that. If placement options are identical then go with the 4000.

No disadvantage on paper maybe.

Why do we continue to evaluate performance on paper and ignore the room/placement?

Hi please do not move backward under ANY circumstance - a good tuner should be able to integrate JTR subwoofers into any system.

Objectively, we know the 4000 is one of deepest/most powerful/etc. residential subwoofers ever manufactured and measured. In many aspects, it IS the Holy Grail of subwoofers. Procella is a decent brand, but would stand NO chance whatsoever. Not just against JTR, but any of the reputable "internet" brands we see on this subwoofer forum.

Subjectively, not only you've had a taste of the JTR 4000, you've actually loved it (it's a different thing if you had NOT liked it), going to Procella will gnaw at your psychologically and bring regrets. I speak from my 30 year experience of being a fairly crazy audiophile - never get rid of anything you love because the what-if's are impossible to tolerate.

At most and if the ultra deep bass makes you nauseous etc. LOL, I would consider going backward to 2400, or 1400, but even that would be a "dangerous" move. All IMHO.

I’ve had one initial consultation with an acoustic design firm. I was moderately disappointed with their mentality of we build what we want and you will like it. It almost felt like they’ve figured out one good system and they believe if the shoe fits..

Where our conversation went astray was in the subwoofer department. They told me two Procella 18” dual sealed subs would clearly impress me and I’d want to sell my Cap 4000. I told them I wanted two Cap 4000s in the room. Then I looked at the skinny sealed mini box that looked like it was built for the back of a Ford Ranger. They want these little boxes to save space behind my screen. They are 12” deep so they believe I can produce serious impactful bass from 4 sealed 18” woofers in a mini box after I’ve been using a nearfield Cap 4000.

I’m not obviously sold on this company, but I just wanted to hear if anyone had experience with Procella subs and if they feel in a 20x20x12 ft room I’d be happy.

Only sure way to know is to compare them against each other in the same room. I doubt they would sound better to you than the Caps but this way you will know that you made the best decision

That’s not possible. I have to build the room designed for one type of sub or another. If I go with the Cap 4000s I would need to build a front stage beneath the screen and hide them under it. If I go with the Procella then I build them behind the screen. Can’t really audition them.

I’m wondering if anyone has experience with listening to the Procella sealed units versus the huge ported 4000s. Procella doesn’t even publish specs to know where the bass stops and how loud. They are externally amplified and they give minimum specs and point to the amps for full performance information.

I’ve owned 5 different subs (all bigger than the last) and am happy with the Cap 4000s. Leaning towards designing the room with 2 of these in mind. Also it’s one fewer to buy since I already own one.

Gotcha. @cannga 's advice seems to be on point. We already know that it takes more sealed subs to get the impact of the ported subs especially near port tune. You already have the most powerful subs one can buy so in no way the math is adding up unless you keep adding the sealed ones till you get to the same level as the dual caps which of course you cannot do....

@otismojo have you already dialed down the LF Adjust to minimum for the wife?

Jeff sent me a new DSP program for the 2400ULF with more range in the LF-cut (-18dB vs -12dB I believe). To me, the -18dB was perfect in Jon's room. We had 4 Seaton Submersives to play with in comparison. This DSP setting is a change you can discuss with Jeff.

All I can say about the Procella subs is that the integrator is simply ignorant about the capacitors of the JTR. Although, your wife likely will be happier with them. I need to go back and read more about your room to be able to comment further. I can't stress enough how important the room and placement is.

Sealed subs are easy to simulate/predict. Roughly, you will need between 12-16 sealed 18" drivers to compare to dual 4000ULFs.

What are the potential dimensions of the new room? Hard slab or platform floor?

I’m the problem not the wife . I like the bass as is. It’s pretty substantial at -20dB and higher listening levels. For comedies and drama stuff at lower listening levels the bass is fine.

The designer wanted to place two 18” dual Procella subs in the front behind the projector screen. We can’t place Cap 4000s there or on the sides of the room without them being “in the room” which aesthetically is an issue due to their size.

The only option is under the screen built inside of a stage to hide them. My room is 20x20x12ft. I’ve got room below the screen, but since the room is already depth limited my options are few. The screen will be 12” built out from the back wall leaving 19ft of depth. For a 14’ wide screen I’m near the focus limit of a projector. So the 4000s can’t be behind the screen either. All concrete floor and sealed room.

My other concern is can the room be built sound isolated well enough so that the bass is contained and not felt all over the rest of the house? Tough issues.

I'm anxious for the 2 week lead time and Jeff has nothing but responsive. Every time I called, Jeff has picked up the phone and was very friendly and helpful.

BTW, I did much research and looked at 2 Cap 4000ULF for my room. @Marc Alexander suggested I might kill myself in that small of a room with those big behemoths.. lol seriously though... 3 2400s in my sealed room is going to be pretty crazy, I can't imagine what 2 Cap4000 would be like. I guess in the future I can always add one more Cap 2400 and it would be like having 2 C4Ks...

Anyway here is another link to the other thread that I started

https://www.avsforum.com/forum/113-su...l#post55625882

I went as far as contemplating DIY but after much research, I found that JTR subs have so much value and positives that it made sense for me to go this route.

I hope to have more to report in 2 or 3 weeks once I receive these bad boys and placing them in my theater.
Wow! You're nuts! I've been contemplating a cap 2400 thinking it's much more than I need or even want in a room about your size. The single svs pc13 ultra I have sounds great and shakes the room pretty good as it is. I can't imagine what 4 would sound, or rather feel like. You've helped push me over the edge. I tried to call and put in the order for a cap 2400 today, but it looks like they're closed on the weekend. Will have to call them on Monday. My wife doesn't much like the pc13 (scared her a few times). I'm wondering what she'll think of the cap 2400.
