I've toyed with adding two DIY sealed 18's for further improved response over my dual submersives.

But it wasn't really recommended, at least that's what I seem to recall.

Well if you plugged both in to sub out one and two and ran Audyssey it will pull down the extension of your sealed sub. But I have thought through this process of ported sub and sealed each into a mini dsp Channel, measure the combined response, make a few PEQ alterations to flatten it out manually, and add your low shelf. Then run Audyssey. All Audyssey would see is the combined response and wouldn't know if one was ported and sealed. The problem LTD02 mentioned to me before is at the port tune you can get reverse polarity happening and cancellations could happen, and happen more with the reflections factored in. It's over my head but I posted the comment recently he made...

IIRC - as far as output.

Orbit Shifter = 1 S1 below 20hz
Orbit Shifter = 2 ported Captivators at around 20hz
Orbit Shifter = 4 S1 above 20hz


dgage - in your post you mean dB instead of HZ.

Also - Orbit Shifter and Gjallarhorns are really quite different designs. The GJallarhorn is several times more more powerful than the orbit shifter at 15hz, how many times more powerful is not necessarily known without testing, but the Orbit Shifter is tuned to low 20hz and the gjallarhorn is tuned to about 15hz. Below tune the Orbit shifter design acts like a single sealed 18". Below tune the Gjallarhorn cabinet completely unloads and becomes unsafe for the driver quickly. At frequencies say 60hz and above the orbit shifter will have a significantly flatter (more desirable) frequency reponse than the gjallarhorn. The gjallarhorn should really be used from 15hz to 60hz because of the design. You get modal ringing points above 60hz on the gjallarhorn. The Orbit Shifter is a full frequency capable subwoofer option.


Lukeamdman, or Ricci can elaborate further if they care to.

Two sealed LMS-5400 would only beat the Orbit Shifter below 20hz. It would take four LMS-5400 in sealed cabinets to beat a single Orbit Shifter across the board.

I hear ya about sound treatments... I am planning on doing that soon (as soon as the construction is fully finished and I get some furniture) before investing any more money. The only reason I'm experimenting now is because I've brought down the speakers form the upstairs game room so I can try different configs.

It's an L shape room, so the back is open to a huge space, which from what I understand is bad for creating pressure for the subs. So, I want to somehow close it off either with thick drapes or an accordion wall. Any thoughts on that approach?

OK with this diagram imagine the seating position is my only on of seats... And it's against the rear wall. Now I have bipols on rear wall. If I go to slant 8s rear wall is probably no ideal... The distances in this are same as mine. So would s8s be better off on side walls.... I can post pics of my room if that helps
post #14675 of 18666
Where is the diagram
post #14676 of 18666








Sound I mount them above each door which is only option to mount to the side. Being up high I figure slant 8s would be best option. Thoughts?

I just realized JL has been making home theater subs for several years now. Back in the car audio era, JL made some of the most kick-ass subs available. I wonder if they have made a good transition to home theater?

How would a nice JL Audio sub compare to a JTR sub, or a Seaton Submerisve I wonder?

I owned a pair of F112's before the Captivators( passive ,2011).
The Caps have same SQ , to my ears at least, and are all over the JL' s in output and dynamics.
First pair of subs in my system that scare me.eek.gif

That and I received lousy service from JL , so I sold the F112's broken with considerable loss.
Form factor is great though. For size they do have considerable output.

So Archea, what is your recommendation for DotJun to bring up his 10Hz response in his room with a single OS? Looking forward to your recommendation simply for my knowledge. Thanks.
post #14680 of 18666
I've heard all the subs in JL's lineup (my brother in law sold them) and can't say I've ever been all that impressed with their performance. The gotham is a beautiful and performs pretty well but is so overpriced its insane. The dealer markup was over 75% on that pig. JL drivers are good as far as the big box drivers go but compared to others you can purchase online and high quality DIY drivers, they leave a lot to be desired.
When I was in SPL and SQ comps with my car, guys would strut in with their JL stuff and think they were gonna walk all over everyone.... it always ended up with them eating some humble pie... ahh those were fun times.

+1

And I'd also like to add that it's not really fair to compare the 20hz performance of one sub to the 10hz performance of another sub. smile.gif

Add sealed subs to pick up the bottom. Everyone around here is terrified of it but it's quite easy if you have some method of dsp and measurement. Check out my theater thread in my sig for details on how I did it with good results. It allowed me to choose the placement of the OS that gave the smoothest response rather than chasing every last bit of extension.

The (3) 228HTs have arrived! Much earlier than I expected, I still haven't finished the 20-amp circuits on the breaker panel side. So the Sherbourn (20-amp plug) can't be used at the moment unless I pick up an adapter, which seems like a waste since I will have the outlet wired within a week or two. I might just get the X4000 turned on and setup and let it power the speakers for now. The other problem is the Cap S2 is not here (or on the way) yet, so I'd have to run the 228HTs in full-range mode. If I do that I will try to avoid any bass-heavy audio.

And here are some pictures of them, they are definitely large and the 212HTs would honestly look ridiculous in my room. The TV on the wall is a 55" VT50 mounted at 40" (bottom edge of TV) to the ground for reference.

If you have a 20amp receptacle to use with the Sherbourn amp; just replace the 15amp receptacle with the 20amp and plug it in. I personally know for a fact that if you're only powering your three 228HT's off of the PA 7-350 you won't trip the breaker.

Congrats on the new toys bro. They look fantastic and I am sure you will enjoy them for years to come.

Get those things off the floor. tongue.gif

Tweeter at ear height is ideal.
post #14689 of 18666
tongue.gif Guess I should have been more thorough in my post! I placed an order with Jeff on 12/27 for the following:

(3) Noesis 228HT
(2) L/R Stands @ 24" Height
(1) Captivator S2

He quoted me 5 weeks as was the standard at that time, but for whatever reason I got a shipment notice on Tuesday (1/7) that three packages were headed to me from FedEx. It was the (3) 228HTs, so that is all I have right now. I'm not going to bother Jeff about the rest of the order until it is closer to the 5 week quote he gave me, getting the 228HTs early is just a bonus from my perspective.

So the L/R CD will be at 37.25" height and the center will be horizontal on top of the S2, which puts the center CD at 27.125" height. I ordered some MoPAD-XLs to give the center a slight incline (either +4* or +8*) if needed.

That Jeff, always shipping orders early before we're ready. tongue.gif

My $.02 ... Pretend they aren't there and wait for the stands and S2 before hooking the speakers up. smile.gif
post #14692 of 18666
I was going to stop in and see Jeff this past Monday but the Midwest storm locked me into a Merrellville, IN motel for two days and nights and I ran out of time.



Jeff called me today and said my three 212's are finished. I informed him that my new construction won't allow me to place them until Spring sometime so one of you lucky ducks will be getting yours a little earlier than you thought.

New JTR speaker day is always a happy day. biggrin.gif
post #14695 of 18666
Hello all, looking for input:

I currently have a set of Paradigm Studio Speakers: Studio 60 pair (fronts), CC690 (center), & a ADP590 pair (surrounds) all V.4.

I just moved into a new home and put in an acoustically transparent screen. I would like to place the speakers behind the screen, but space is tight, so I have been looking to replace for some low profile speakers. In come your Triple 8HT-LP & Single 8HT-LP speakers for LCR…

Factors:
• This set up is 100% for movies
• Room is 2500 cubic feet (open to stairwell and hallway)
• It will join dual PSA XS30’s
• Amp powering the speakers is an Outlaw 7500 (200 x 5)
• I do not listen at reference, about 10db’s below reference for movies

Looking for feedback on the following:
• Will I see much benefit going with the Triple 8HT vs Single 8HT for the front 3 speakers?
• What can I expect in moving from the Paradigm Studio’s (which I love)
• Aside from Loudness, what benefits do the Triple 8HT’s give me over the Single 8HT’s? Over my Paradigm Studios?

Other considerations??
post #14696 of 18666
I can help with pat of your question. I came from studio 100's and went to triple 12's. The difference for movies really is night and day. I was powering the paradigms with an Emotiva xpr3 but the JTR's just trounce them in dialogue clarity and impact in dynamic scenes. I find myself jumping a lot more when sudden noises or explosions happen because the speakers aren't compressing and taking the impact out of the scene. I even like the t12's equally for music. I have never had a t8 but have several single 8's and they sound very similar to the t 12's as far as dialogue clarity and overall feel. The triple 8 should add more output and a bit more impact over the singles so for most content and in a smaller room than I have I would think the t'8s would still provide a considerable improvement in your movie experience.

Thank you for sharing your experiences. I understand diologue clarity, great to hear. Regarding dynamic scenes, do you mean it was able to play louder, or did it have a greater presence in the room? Sounds like you have Single 8HT's as surrounds. Have you tried the Singles as mains to test? I appreciate your feedback.



Also, I should clarify, I would be looking at the "low profile" or LP versions of either the Single or Triple 8HT-LP.

Between those two options in your space, I bet a 5.1 setup with all 8LP would very good. Think timbre matching...smoothest overall sound from all speakers. Or 228 for LCR for a bit more $.

While I can't compare the S8's or S8-LP's to the Studio I could give you a quick comparison's of my 228HT's and the Studio series.

Before I bought my 228HT's I had the opportunity to demo some Studio 100v5's and matching CC690 center channel, I have a friend that works at an AV store that was able to lend me the speakers for a week to try out. So I really like the speakers in the store, but once home I quickly started to realize this wasn't the case anymore. Well at least not in my room, the louder I would turn up the speakers the less and less I liked them. They started to become harsh sounding and would lose composure.

I would have to think that pound for pound the S8's would be a step up just knowing how great my 228HT's sound compared to the Studio stuff.
