These T12s are mutha faaahhhkkkkin SHAWHEEET!!!!

I thought my RF-83s would be hard to beat. Since I got the 83s, I have been soooooo in love with the sound.

Got the T12s in today, and without even any EQ they are so incredibly BEAUTIFUL.

I cannot begin to explain the clarity, detail, and PFO these things provide.


I will go deaf, lovingly absorbing such beautiful output.

EDIT: Disregard this last part:

Unfortunately, I'm not too pleased yet with the Captivators. I hope it's a cancellation issue.

Tapping the clip lights on a bridged Crown XLS 5000 per Cap, there just doesn't seem to be the output I expected.

I obviously need to run some sweeps, but the dual Cap visceral feel is currently less than the single Klipsch RW-12 I was using before.






From my comments in the Captivator thread:

Quote:


I think we're good now!!!!!!!!!!!!!

I've had them running for about 4 hours today (plus yesterday for awhile) at a moderate level. I turned them down for awhile (half hour or so) to talk with a friend and then turned it up really loud to take a shower. My lights were pulsing with the music and there's PLENTY of bass.

The fans are in turbo mode!!!!!!!!!!!!!!

SWEEEEEEEEEEEET!!!!!!!!!




I LIKE IT!

Part of this project was neoprene padding to go under the subs and under the T12s on top of the subs. Friction and scuff protection was what I was after, but I think it has served as a bit of a decoupling because the bass is REALLY there with a purpose, but the house rattles less than it did with the RW-12 that was right on the floor.

It's only 1/4", so I don't think it can provide much as a decoupler.
post #3664 of 8265
It's almost a certainty you have cancellation issues. Have you tried just one Cap instead of two? Once you get the set up issues resolved I suspect you will have as good of feeling towards the Captivators as you do the T12s! the Caps are monsters!
post #3665 of 8265
I second Sidewayz, definitely a cancellation issue. I got to hear dual Captivators at the KC meet on an iNuke3000 and I can't imagine someone not being impressed.

@geomania That is one awesome system, much respect! Probably, my dream speaker set up.

Umm, as noted above, you are dealing with a serious null at the LP and/or the amps are malfunctioning or, set incorrectly. I assume you level matched them with the speakers using an SPL meter, correct?

Try one Cap in the same location as your RW-12. Not that the Klipsch isn't a nice sub ... but the performance delta should be easily heard/felt.

No EQ yet, as I said, but I can't put a Cap where the RW was. Not enough space, but the one on the right is very close to where the RW was.


Can't be a LP null, because the whole house is the LP and there's pretty much nowhere that has the same impact as the single RW. That only leaves cancellation.

I'm going to work on sorting it out today.

Have you used the crown xls before with any other subs? Also, is your receiver a pioneer?

No to both. It's an all new setup from the EQ to the speakers. The "receiver" is an Alesis MultiMix that I've had for several years. and my iPod runs through 2-track.

(It's my band room, not HT.)

Those speakers look bad-a$$ sitting on top of the Caps!

I hope you figure out what is going on with the subs, something has to be very wrong.

Ah, my mistake. I was thinking it might be an issue with a receiver getting enough voltage to the crown amp. I asked about pioneer because I had that problem with a pioneer myself.
post #3672 of 8265
I just picked up a pair of JTR Triple 8's, they're vented. The seller claims they are 2010's. Is there anyway to confirm this? Are there any physical attributes that separates the earlier models with the 2010s? I'm coming from a M&K S-150s and I'm hoping these will sounds a bit "bigger" while maintaining equal if not better dialog intelligibility.

The 2010s are actually 12x12.75x26..........at least mine are. Here is the post of their introduction: http://jtrspeakers.websitetoolbox.co...iple-8-3459401

The cabinets could have been changed though later in the year before a 2011 model was announced??? I don't know that answer, but mine indeed are 12x12.75x26..........and mine have the huge binding posts on back.

post #3676 of 8265
Now that I upgraded to a high quality sub (Seaton Submersive.. almost bought a cap sealed), I now realize that I eventually want to upgrade all my speakers as well to something from JTR or Seaton.

Although Seaton's Catalysts have gotten my attention, the price tag is a bit too much for me to realistically afford anytime soon, even if I started going Deuce Bigalow and prostituting myself.

The Triple 12's and 8's seem to be the next best thing, and would be much more affordable for me. My question that I haven't really seen answered before, is how do the Triple 12's (LP and vented) sound compared to the active monitor Catalyst 12-C? My room is only about 3000 cu ft and I'm more about quality and clarity over deafening SPL.

Is the difference in active dsp vs passive that much more noticeable? Is the difference in price and value in the JTR speakers that much of a better choice?

Congrats on the Submersive upgrade and on realizing that in order to fully realize the benefits of a great subwoofer like the Submersive, you also need high efficiency speakers. I also agree that the goal should be sound quality over pure SPL with an emphasis on dialog clarity.

While the speakers (including subwoofer) are very important components, the most important factor in getting the best sound in a home environment is the room itself. Having a sound friendly room (dimension wise) and treating the space with appropriate absorption and diffusion materials can be more important than the specif loudspeaker choices.

I would also consider equalization products like the very user friendly Audyssey MultEQ or slightly more challenging professional equalization products as very important elements in getting a great sounding room.

I'm not dodging your question as to what speaker sounds better but simply pointing out that these other considerations may have more impact on sound quality than the loudspeakers.

To your question, I like my JTR's speakers and have no desire to change them out. I have heard Catalysts (with Submersive's) on several occasions and was very impressed. There is some magic in the powered DSP controlled Catalyst sound and they are undoubtedly one of, if not the best choice for a fantastic sounding HT. But as active speakers they present some logistics problems like power at each speaker location and needing to use XLR cabling rather than speaker wire. Certainly not insurmountable problems but should be a consideration none the less.

I know this all sounds very PC and generic, but I find the buy my brand recommendations suspect. Obviously, no one can answer the question as to which speaker sounds better and what you might prefer except you. So the best suggestion I can give you is to get out there and listen to what you want to buy. If that isn't possible then it's a leap of faith. They will almost certainly sound different in your room anyway. I'm not much help, am I ...

Two Captivator S, three Triple 12HTs, four slanted 8HTs scheduled to ship mid to late next week !

I want to thank RMK! for letting me demo his fantastic set up about a month ago.

Nyal Mellor from Acoustic Frontiers is helping me with the overall theater design, installation, acoustic treatments, and audio calibration.

I suspect the amp. The Crown XTi 1000 had very weak output 20hz and down. Go to the DIY speaker and sub section. At the top there is a measuring amps sticky. Take a look at the Crown XTi 1000.

For the T8/T12 - is there a reason the coax is in the center? Does it matter if it is moved to the top - is there an impact on sound? Just thinking from a stand perspective as a middle position would require a taller stand...

Thanks.

I have 20" stands for my mains and wides, to have the center of the center-mounted T12HT-LP coax at 39" from the floor. I filled them with sand to weigh them down and increase stability.

The T12HT-LP surrounds have the coax mounted on the top and are on 24" stands.

They can be moved to the top. Jeff built my T12s with the coaxial at the top to work with my layout. Jeff can guide you through with details. It involves removing the center first to determine which side of the cabinet is up.

I edited my post. I didn't realize I hadn't updated this thread like I did the Captivator thread.

Next, any LCR main should ideally be at least 1/4 wavelength of any freq in it's operating passband from any adjacent boundary. Additionally, acoustic absorption should be placed behind and immediately to the sidewall sides of mains to mitigate SBIR issues. This is a serious consideration.

Here's two links on SBIR (speaker boundary interference response)
SBIR
SBIR

Couple of follow ups:

1) Crossing in front of the listening position. I know the Geddes emphasizes that for his speakers. Are you saying the same for JTR's? Pretty steep toe-in, correct? Is it 45 degrees or not that sharp an angle?

2) "...should ideally be at least 1/4 wavelength of any freq in it's operating passband..." - the T8 sealed goes from 75 to 24k. At 75Hz, the corresponding 1/4 wavelength gives a distance of almost 4'. Which implies that I either move the speaker 4' from the wall, or put some GIK-type absorber to reduce the reflections.

Thanks for the links to SBIR as well. That and VER look to be two things to look out for.
post #3689 of 8265
I am looking for something that would raise the speakers 18" or so, solid (so they can support 50lbs), and decent enough to put in a living room.

I have looked at Racksandstands.com, and Standsandmounts.com but haven't seen anything I really like. Bello and Lovan are two brands I looked at in particular.

Any recommendations on stands for the T8's?

Thanks!
