JTR Captivator - Page 4

Its custom made, just for you, twice the price





Thats Death-Vator

WTF???? Weirdos!

Well I swapped out the passive radiator last night and all is good now. This thing is beasting anything I throw at it. Actually just finished cleaning up a mess in my laundry room. Thanks to the cap, some things on a shelf took a spill causing the entire shelf to become unbalanced and the whole thing just crashed to the floor Will write a better review when I have time but to all those who are on the fence do not hesitate to jump on anything Jeff creates.
Stopped by the shop yesterday and the quintuple and new veneered triple 8's are flat out gorgeous, I know some of you have purchased them recently and all I can say is lucky you!

nice setup, what did you use to mount the center speaker?

Nice setup Pinktri,
I like the acoustic treatments under the L & R speakers
Looks like the Captivator got a center divider in it's port mouth.

Thanks. The mount is made by sanus designed for CRT tv's. I cut the arm a little so it did not hang too far out. The speaker is actually strapped in and is super secure. I believe it's rated for 120lbs with 4 lag bolts straight in the stud.

how would the output on this unit using a 500watt amp compare to a Submerssive?

maybe RMK can answer that since he's heard both. I've run the Cap on a single channel (currently bridged) around 600watts and it sounded fine but definitely lost some headroom

To be more familiar with this design, what exactly is a band pass sub (captivator)

is that like a folded horn?

Bandpass designs have a chamber in front and behind the driver.

Ok, so I used "the google" to find more info on this design. It seems there are different types of "orders" 4th and 6th?

Most of the info. was found in car audio forums not pertaining to home audio.

Yeah, we both went to the same sites, the same way you understand this designs is exactly how I pictured it.

I know Mark was involved in this design along with Jeff (audio magicians) and that Marks offerings are different in some aspects. His bandpass subs are also not well know. What I mean by this is not many people know about them. Iam sure they sound ridiculous as well.

Just curious why there is so little info on this design and why (to my knowledge) no else in high end audio is using this design. Only Mark and Jeff.

Everything that I read pointed to the fact that this design does not lend it self to a good transition to high fi audio in the home. Only PA systems, with the ultimate goal of high spl levels with little concern for sound quality.

So I read negative comments about such a design and think this may not be a good sub, but then you read and hear comments about Marks and Jeff design and how it takes your breath away with it performance and sound quality.

Iam not by any means knocking this design, I trust Jeff and Mark as well as the few owners of these subs when the say they are fantastic.

Just wondering what magic pixie dust they are sprinkling on top of these subs that makes them one of the best options for home theater use.

I think no else does it because of costs (design) and size of the sub.

pinktri adn RMK!,

Valid points, its is a difficult design and expensive. Like most sub designs there are many factors to get right and most don't. Maybe why there are negative comments by those that have tried (DIY) and did not get it right. This would lead to lowered expectations and beliefs about the abilities of this design in other venues like home theater.

Also, ported and sealed designs have been the main stay of subwoofage for so long, many feel reluctant on taking RMK's leap of faith into other designs that may offer greater performance and sound.

I was just thinking of these as I wrote: The flavor of the month regarding subs is folded and tapped horns. They offer efficiency and dynamics needed for the HT environment. Which makes sense. Jeff as gone a different route, he choose a folded horn for his growler which is intended for PA crowds and choose a bandpass design for his home theater customers. To contrasting designs in other wise contrasting environment.

I believe most (average individual if made to chose) would have choosen the folded design for HT and bandpass for PA.

The captivator needs a bigger audience, a say subshoot out!!!

Jeff, how does a bandpass design differ from a ported design sound quality wise? Is it cleaner sounding? Just wondering about the benefits. Thanks.

Hi Tom Bley,

I have one 6th order bandpass subwoofer and you are right it sounding very clean and precise, usually 6th bandpass design has very high sensitivity my sub has 103 dB 1w/1m so it is quite loud it is in the left back corner near two back doors on that video:

Regards!

Wow, thanks for the info. I also like my T-8's with the Line-X and Baltic Birch ply. The other thing I noticed on Pinkti's is it doesn't have the nice round over edges that yours does. I'm wondering how just your two Cap's with an action movie sound or have you just used the two for music?

Tom

RMK!

Your captivators also have rounded edges, pinktri's caps. are square.

I read and article a few months back regarding wood properties and its (wood) ability to properly reproduce sound.

I can't remember exactly what the recomendation was but BB and MDF where involved in the study.

One reflects sound and the other absorbs sound.

I wonder if that affects the sound in Jeff's designs, if any?

Gotcha. thanks for the info. I wonder if there is something simple and in- expensive that could provide adjustable HP filtering. I'm suprised you heard it bottom especially w/ the Danleys but, I guess that's still is a possibility because of no HP filter on them.

I wonder if you hit bottom or reached the PR's limit.

Thomas, is the E.D. box on top of your QSC providing a HP filter for your Cap?

For the money, it looks like a good solution.
