I have the center crossed at 60 and the L/R crossed at 80. Music is strictly 2 channel. I like how dialog sounds crossed at 60 for my center channel. Mid bass punch is never lacking with movies or music. Before, I considered a growler because of mid bass issues but that's not the case any more.

mojo I totally understand!!!! This sub is sheer power! It's a real physical subwoofer if that makes and sense. It's hard to describe but it's definitely something I FEEL rather than hear. SERIOUSLY who needs shakers when you have a CAP

I have been waiting on a Growler since November but I have the Cap. I want to see how I can blend them in together. Seems to be a long delay.

I have tried Jeff all week with no response both PM and Phone. Not sure what is up, I know he is a one man show and busy.

Will do.

Eventually I am going to get another Cap but need to save up. Has anyone had success with the EP4000 and 2 Caps?

I would keep them at 8 ohm and Bridge down to 4 Ohm for both.

The question I have is the Speakon "OUT" of the Cap for linking another one to the first....would that yeild a 4 ohm load?

Thanks

Perhaps you're just trying not to bother Jeff, but he's probably the only one who can answer those questions.

Hey Vitamin, He was shipping out mine today! I think jeff was waiting for the
drivers to come in and they came in this week so they should be in stock now.
I think the shipping is around $120-$150 depending of course where you live.

Yes if both are each 8 ohm for linking you get 4 ohm load! Looking for do the same for two CAPTIVATOR-PRO in the future

Jeff, was kind enough to bring by a powered JTR Captivator Pro. My setup consists of both an Elemental Design A7-450 and Epik Tower in one corner, a def tech signature in each of the 2 other corners. Placed the captivator in the free corner in the back room. Room dimensions are 17 feet wide, 8.5 ft ceilings and 29 feet long closed in. Ran a quick calibration with the Velodyne SMS-1 and got everything dialed in. Adding the captivator boosted my 12hz frequency by 6 db. The frequency response with all subwoofers going was beautiful from 12 hz to 100 hz.

Played WOTW and the POD seen was extreme and visceral. The impact at the seating area was astonishing the air movement and chair movement was scary as was air flowing through the hair

Musically it the power captivator pro blended in nicely with the rest of the subwoofers.

I am getting ready to put an order in for 2 powered captivator pros. Haven't told Jeff yet, will call him shortly. I will now have a total of 5 subs in the room

Alright,

Here is what I am trying tonight.

A friend is bringing over his XTi4000 and I have and XTi 2000 and EP4000.

We are going to hook up the following just to see how it all sounds. (nothing else to do on a monday night)

1. XTi 2000 in Stereo going to Left and Right Triple 8.
2. XTi 4000 in Stereo going to Center Triple 8 and Growler through LFE Sub 1 on AVR.
3. EP4000 Bridged into Captivator through Sub 2 on AVR all ran through SMS-1 (LP at 50Hz to start)

We will disable the crossovers for L/C/R through the DSP in the amps and use the AVR to decide the crossover (Probably 80Hz to start)

USE DSP for Channel 2 (Growler) to set a from 50 Hz to start using Band Manager Software and leave the AVR set at 120 for LFE out of AVR

Will try to blast the Triple 8's with 800 to 1200 watts and see if 650 watts will be a good start for the Growler.

Who knows, never done this before so working the DSP in the XTi's, messing with SMS-1, and run Audessey should make for a long night or will have to continue on Wednesday night.

Sounds like a lot of trouble. I like it.

I'm a step away from ordering a powered Cap. I'm getting weaker by the day.

Spoke with Jeff,

He said changing the old cap into a new one only involves making some pilot holes into the divider and then hitting it with a hammer to knock it out.

So there's really no cutting needed on the outside woofer hole?

Need to work out the numbers and see what I can do.

might get the woofer and install it then start trying to find an amp


My cap's finish is pretty beat up it from day one and beyond that moving it around so it won't look pretty but should sound good.

Well we went through some paces tonight but not completely.

I can only have the Cap and Growler on my stage behind my screen for space issues but we moved them left, right, center, facing front, back, left, right. (took a while).

We found that putting them back to back in the middle with my center channel on top facing the Cap towards the left corner and the Growler facing the right corner was the best.

- With just the Cap. alone it was flat from 17 Hz to 50 Hz then a huge null from 52 Hz to 73 hz down about 20 db then flat again from 75 Hz to about 115 Hz.

- Then we ran both through sub 1 (Cap) and sub 2 (Growler) output on my Integra AVR using 120 hz LP for LFE. We used SMS-1 on the Cap and dialed it in as good as we could. Then Turned on the Growler and used DSP on the Xti 4000 (Channel 1, Not bridged). What tried a number of High Pass settings and it turned out nicely with some time. We ended up using a HP of 54 Hz (48 Butterworth) to get an extremely flat curve in the LFE from 18 Hz to 120 Hz.

To this point, the Growler has helped tremedously in shaping out the null in 3 different listening positions. Just watching a few movie scenes it was evident the overall performance was much better then in the past.

What is nice about the Growler is that for Music, I can basically shut off the Cap and get extremly great bass and kick. So far I am happy, and with all the discounts around the holidays and the extra multi purchase discounts the Growler was almost free at the time compared to purchasing now. I also have a friend that would buy it for DJ'ing so It was worth the time and it will buy some time as I save for another Cap in the future to daisy chain with my first.

All is good....

Goal is to have 2 Caps up front and "Maybe" get my MFW-Turbo for my "dead" subs to have 2 of them in back left and right of the couch. That should settle it all for me. : /

Last question was Audessey was having trouble picking up the distance of the Growler. The "Physical" distance in any position ranged from 14 feet to 11 feet.

Audessey picked it up different each time ranging from 22 feet to 35 feet. I know there is a 7 foot horn fold but...

I tried my Captivator over at my girl's house tonight to hold her over until the one she ordered arrives. So far the amp is a big bottle neck. Using a QSC PLX 3402 with one channel doin 2 ohms it just doesn't have the oomph of my Face Audio F700. In my set up when playing the Incredible Hulk, (the scene where the Hulk is punching Abomination with the cop car)the Cap pushes enough air out of the vents to blow out a lighted match 7 feet away. With the QSC you can hardly feel any air even with a hand right up to the vents. Next up will be a Crown K2 then the Face Audio F700 to eliminate that part of the equation. Then gotta focus on situating it in the room cause as of right now it doesn't have the impact it does at my place.

Yeah, as Mike alludes, something's amiss. According to http://www.avsforum.com/avs-vb/showt...8#post12938838, your amp should be putting out around 1800w on that channel. That's pretty much what my EP4000 is putting out in bridged mono at 4ohms, and at that wattage, my Cap puts out stunning amounts of deep bass.

Perhaps the issue is entirely placement-related?

As was discussed previously in this thread, there are certain AVR-pro-amp combos that don't work out well without something in-between to boost the sub-out signal.

Other than cost, what are the disadvantages (if any) of ordering a power Cap instead of the passive version and providing your own amp?

I can only think of two disadvantages.

1. In case of amp failure, replacement might be more of a hassle with the powered Cap.

2. With the powered Cap, you don't have the option to "double down" with two Caps on one amp like you could with a separate pro-amp.

The main advantages of the powered Cap are a response curve optimized by Jeff with the amps DSP and, of course, 4000! watts.

The sub level was at -6 and I still had more left in the tank. Problem is it just sounded loud but no oomph.

That sounds like either a problem with room acoustics or an problem with integration with the mains. I'd suggest frequency response measurements to diagnose the problem.

One potential weakness of the Captivator (and perhaps the only one that I have found) is it's upper bass response. My tests show that it tends to roll off above 80hz or so. If the mains lack strong response down to at least 80hz, the upper bass region may be lacking. That may account for lack of oomph.

I agree, it is probably a room issue and should measure the response at that house to compare to the other.

I wonder if that's by design, or if the powered version shares the same roll off with the DSP controlled amp when compared to an external amp...
