JTR Captivator 2400 or Captivator S1

Hey guys, I need help deciding which I should go for my home theater in the basement. Ceiling height is 7', and room size is 12' x 19'.

I have KEF Q900 for fronts, Center channel KEF Q600, and Yamaha ceiling speakers for surround, powered by Onkyo 929.

The sub I currently have is Paradigm DSP 3200. I want a sub that can produce heart thumping bass. I mostly use my home theater for movies. I don't care for music part.

Would the ported Captivator 2400 be better or sealed S1? I would appreciate some suggestions.

I read on this forum about Submersive, which model would be better?

I was very seriously thinking about buying JL F113, but that's very over priced subwoofer. I live in Canada and a local dealer sells it for $5K.

I emailed twice yesterday and today to JTR from their website, I haven't got any replies back. I tried calling them too, but no one answered the phone. I am wondering whati their customer service will be like if I run into any issues with the sub.

Thanks.

Captivator 2400 over a Captivator S1 in my opinion. I loved my ported captivators. They are power houses.


Jeff is sometimes hard to get a hold of. He's a one man show. Give him a few days, check your junk mail too incase his reply went there.

I agree. I have a cap s1 and wish I would have got the ported version. To be fair to the subwoofer, I really need multples in my room (5000 cf).

To the OP, The s1 would probably do very well in your space so I guess it depends what you want.

Jeff has given me great customer service.

Wow! 5000 cf? You need dual Orbit Shifters..

I have dual FV15HP's in a living room probably around 5,000 cf give or take and they perform quite well. I can't even imagine one orbit shifter in my room let alone two.

Cap 2400 will do fine in that room...It has a boatload of output on tap from 20hz on up.

I was looking at the S1 and Cap 2400 too. Like my room, your room is not too big so ether would work fine. Even more so if you room is sealed like my room. I have a large screen up front so for me a Captivator 2400 would be too tall at 30". I have no room to place it in the back or sides. The S1 is really compact for an 18" subwoofer so that makes it ideal for those with limited placement. The Cap 2400 does play lower louder so that is a plus and only cost a bit more. I currently have a Velo HGS-15 (which is sealed) so may add a second sub like the Cap S1. Two subs do assist in evening out the bass.

Thanks guys for all your suggestions. I really appreciate it. I ordered the Captivator 2400 ported subwoofer. Jeff emailed me and told me that he'll be shipping it on Monday.

I will let you guys know how I like it once I have it all set up and watch a few movies.

So far I have only good heard good things about this subwoofer. Hopefully it will sound better than the Paradigm DSP 3200 that I am currently using.

Thanks again to all of you great guys that answered my question. I really appreciate it.

I received the captivator 2400 yesterday. It's a huge sub and a very heavy one.
It didn't come with any instruction manual or the subwoofer cable. The only thing it came with is the power cord.

I was confused as how to connect it to my receiver. After doing some reading on this forum, I went and bought an XLR male to RCA male cable.

Maybe I didn't conneCT it right, I am not getting very good bass. Mind you my paradigm hit much harder with volume know only turned quarter way.

Any suggestions? Am I using the right cable?

Emailed Jeff from JTR this morning, but no replyou yet.

You ordered the right cable. Is the sub in the same place as the paradigm? Do you have a receiver that has an auto EQ such as Audyssey, which sometimes really kills response? It could be that the sub is just slightly in the wrong position in the room causing your MLP to be in a null. I would try the sub crawl. Put the sub in your main listening position (putting it on your couch will be a bit of a pain but it really works well), play some music with good bass notes and crawl on the floor where you would be able to put the sub and see where it sound the cleanest and puts out the most SPL to your ears.

Doubtful there is anything wrong with the sub. The Captivator is one of the most powerful you can buy! Im sure others may have some answers for you, and dont email Jeff, make a phone call. Hes a one man show and is generally always busy. Trust me you'll get this figured out and will be in bass heaven!

It seems like you bought the correct adapter because I'm assuming your receiver has RCA sub outs and the Cap is XLR so as long as it fits on the sub end you should be ok. That Cap is tuned to 17.5HZ so you should be getting good output from whatever you're crossover point is down to 17.5hz then it starts to drop-off. In order to help with your situation, you'll need to explain how your hook-up is. Does your receiver have some sort of room correction and (if so) what level did it set the sub to? And what is your crossover set to? And the most important thing of all......pics????

Your receiver could have also set your speakers to large. Go in and manually turn them to small

Thanks guys for all your suggestions. The receiver I have is an Onkyo TXNR 929. Yes, it has RCA's for the subwoofer. Two subs can be connected to it. I ran the calibration on my receiver, and the sub is set to 80Hz and I turned the sub level in the receiver settings to +5db and Captivator to full volume from the back and I put on Hulk movie. it sounded pretty decent, but I was hoping for more hard bass since this is a 2400 Watt amp sub.

I will try to post some pictures later. Oh and the Captivator is placed in the same exact spot as the paradigm was. Anyways, whatever the bass it was outputting, was pretty tight, which I am pleased with. But I wasn't really thinking that a 2400Watt Sub I would have to turn the volume knob all the way up to get some bass out of it.

I have ordered an adapter, which I will have next week, which will allow me to use my monster subwoofer Male RCA to Male RCA cable. Maybe this cable is not a very good quality cable that I am using to connect to the sub.

I had to run around and make so many phones call at so many stores. Finally I was able to find a last one at one of the music stores. None of the electronic stores have this cable. That's why I wish an adapter or a cable was supplied with the Subwoofer.

Are some of you guys using this sub? If yes, do you have your volume knob on the sub turned all the way up?

It sounds like your output from your avr might be pretty weak, have you turned up the sub trim volume on your AVR?

When you say there isn't much output, is the driver on the Cap moving in and out a crazy amount? That driver is capable of a ridiculous amount of movement so if you aren't seeing tons of movement when you crank it up something is wrong and the sub amp isn't getting a strong enough signal.

I bet you have it turned all the way down rather than up. Turn the amp dial on the back of the sub the other way. You laugh, but I just had this conversation with someone a couple weeks ago and he had four speakerpower amps and they were far too loud, he thought the gains were on min, but thet were maxed out.

Set speakers to small, set crossovers to 80hz.

When setup properly there isn't a room null on this earth that could make a captivator sound weak compared to a paradigm.

Thanks Carp and Archaea for the suggestions. Archaea, I set the speaker's to 80Hz and turned up the subwoofer level in the receiver settings. I seem to get be getting good bass response from the sub now, but I know it could be better. The driver moves fair bit, but not like the way I have see on some youtube videos of captivator 2400s.

I was trying to post some pictures of the settings, but I couldn't. I guess the size of the pictures is too big, so I couldn't upload them. I will try to take pics with a different camera and try to upload them again.

Have you tried running the sub with Audyssey turned off. Just to see if it is neutering the subs power.

Where did Audyssey set the sub trim? Was it in the acceptable range (above -15db)??

Is the bass stronger anywhere else in the room?

Thanks guys for our help and suggestions. I turned the Audyssey off and changed out the sub cable with a better quality one that I received today.

The bass response is good. I am happy with it. Finally starting to like the Captivator 2400. I put the Despicable me 2 on for the kids, and the sub was hitting pretty hard.

I am posting some pictures of the settings of my receiver. Feel free to make any suggestions.

I will post a video of the subwoofer in the next few days.

Harry,

Checking in to see how thing are looking with the 2400 as I'm looking at this sub as well? You didn't sound like it blew you off the water with its performance, Is that still the case? Which XLR male to RCA male cable did you end up purchasing?

Sorry for the late reply. I have been using the sub for a few days now. No it didn't really blow me off the water. It's a good sub with respect, tight bass, but I went ahead and re-connected my Paradigm DSP 3200 again, just to compare between the two. I turned the gain about quarter way up on the back of the Paradigm sub and the driver moves crazy amount of air, but Captivater's gain turned up 3/4 way almost fully, but the driver does not move as much compared to the Paradigm.

I had very high hopes on this sub, oh well. I mean this sub has a 2400 Watt Amp on the back of and still not moving the driver the way it should with the gain turned up almost all the way.

Now i have my paradigm connected as well along with the captivator. With the paradigm gain turned less than 1/4 way, I could feel the ceiling tiles vibrating. If I turn off the Paradigm sub, not too much with the Captivator.

Maybe I will try to call Jeff and see if he has any suggestions.

Sorry if I disappointed you with my observation, but there are others here for whom the sub seems to hit pretty hard. I was hoping for the same for me, but with two subs now, my home theater sounds pretty good.
