Official JTR speaker thread - Page 139

Hey guys, I owned both the new T8 LP and the original T8's and I like the newer version better. They have more feel to the music if that makes any sense. BTW, they will play fine at 80hz if ones needs that crossover. Jeff makes damn good products and we are lucky to have him as a part of our community. I believe Jeff, Mark Seaton, and Danley have taken HT to a new level and paved the way for other companies to follow along with cheaper iterations like eD and CHT. You can always try JBL pro or something like that but they are enormous so all I can say is that HT has never been better!

Audyssey XT crossed my T8 LPs @ 80hz when I first ran it.
I ran Audyssey a few months later and it crossed them @ 70hz. Not sure if they were just more broken in or what.

PS...I have my T8s- Lp listed in the forsale section if anyone is interested.

Hi giomania, Like to hear your thoughts on the t12lp's sealed. Just this week i ordered them myself, have not read anything about them here. I'm using them in my dedicated theater room, the room is treated and is about 3000cf. Thanks!

Thanks

At your request, RMK.

Not readily apparent in the frontal shots are the big subs. The Captivator lurks hidden away in the left front corner while the PB13 inconspicuously serves as an end table. They are not so much seen, but easily felt.

I might power up the RS850's with an currently unused amp that's sitting in the rack. Then I can switch to them for a slightly different audio flavor if the mood strikes.

Cool! Good to hear your going to have a system again. Are you going with JTR subs again?

If you do not mind me asking, why are you selling them?

The difference between the freq response graph on the sms-1 and the xtz room analyzer was huge in my room. The xtz showed a lot more peaks and dips than the sms-1 did. When I made a slight eq change on the sms-1 I could see the change very easily when I measured with the xtz, but on the sms-1 graph it was much harder to see. I love the sms-1 for making eq changes but for actually seeing what is going on in the room I don't think it is useful.

I upgraded to Triad Gold LCRs (newer versions) but got them used at a great price. In my small room (1150cu ft), I feel this is an upgrade but my thoughts might be different if my room was much bigger (2500cu ft or bigger). Its possible the dynamics of the JTR would pull ahead in a larger room.

Keep in mind the Triads new are double the price of the JTRs new.

The SMS-1's graph has a lot of smoothing, I think it's like 1/3 or something. You probably ran a higher resolution graph with the XTZ which will undoubtedly show a more true response. In reality a difference of +/- 3db is not going to make a huge difference to most people. We definitely are not most people on this forum though

I have used the Omnimic and REW in conjunction with the SMS-1 and it's true there is a difference but not enough to put up with the added steps involved. To me the SMS-1 was close enough and once you know the difference you know how to read the SMS-1 graph more accurately.

The frontal shots were apparent to me What is that movie anyway?

I was thinking it was a home movie ...

Maybe there is something wrong with my sms-1 microphone because it was maddening trying to get a flatter response until I used the xtz.

Do you like my wife's wings? Actually, it's sci-fi/horror movie called "Splice" which just happened to be on the tube when I switched it on for the photos.

The SMS-1 screen graph resolution is quite low compared with XTX or REW. It sort of ignores very narrow band frequency anomolies, but it also seems to reflect the way we actually tend to hear things. Our ears also are not sensitive to very narrow band changes.

I agree.

Never watched Splice, looked a little freaky, apparently I was right

Check out the alien/angel winged girl from splice in human form, might have to check out that movie after all

Dragon, I have quoted a bunch of my posts on my system setup above (Click on the link to see any pictures posted), and will add the following:

I upgraded from 11-year old 7.4 Mirage Omnipolar system to the 11.4 JTR setup noted above. What I am saying is that in my case, the upgrade was significant, so keep that in mind My viewing/listening habits are currently 100% movies.

I also had Mark Seaton perform my Audyssey Pro calibration, so be assured he squeezed every last ounce of performance out of my setup. Mark is very meticulous and was at my house for 11 hours total! He first takes the Audyssey measurements. Next, he uses acoustic measurement tools & software to adjust the sub distance, ensuring the best output at the selected crossover frequency. Finally, he starts tweaking the Audyssey Pro target curve, loads the changes, and then listens to program material to check the result. He repeats this last step numerous times until he is happy with the result.

What I have noticed in my new setup versus the old, is how much more accurate the system is; a poorly recorded soundtrack is noticeable. For example, this past weekend, we watched "Insidious", and I noticed a lot of the dialogue in one particular filming location of the movie sounded terrible with echoes. It changed when the filming switched to a different location, so it may have been the director's intent, that particular set, or a re-dub perhaps. Anyway, I like the accuracy in JTR setup.

The other thing I like is the dynamics / realism. I tend to jump a lot more now if I don't know something is coming, as the sound just has a lot of impact.

I hope this helps.

I REALLY liked the SMS-1 (owned several) and miss it for the ease of use, multiple settings and remote switching. I am now a slave to Audyssey XT32 and it's mysterious process. Blind Faith or quite possibly Expectancy Bias is at play here.

I let Audyssey do most of my eq'ing, but I use the SMS-1 for initially tweaking the crossovers and the phase particularly to get all the various different subs playing nicely with each other. After Audyssey does it's thing, I then use the SMS to create custom pre-sets for different circumstances such as for movies or music that are weak on bass. It's also nice to be able to easily raise and lower bass levels by remote and then be able to easily reset them back to normal.

Do you have XT32? It supports two distinct sub outs (Integra 80.3) and running those through an SMS-1 with mono output defeats the purpose. I suppose I could look at the output of one sub at a time, but I would only be able to adjust one of the subs FR, levels and phase relative to the combined output. Sounds like a useless exercise to me. Now, a dual sub SMS-1 would get my attention.

Onkyo/Integra's implementation of Audyssey XT and XT32 pretty much makes most sub EQ's no longer necessary. I wouldn't use the SMS-1 if I didn't need to apply boost down low to my DIY subs.

Here is what the response looks like with only XT32 out of the Onkyo 5508. Notice how they only filter I have moved on the SMS-1 is the 3db boost at 16hz which was later maxed out at +6db:



The odd thing though is I did have to use the SMS-1 to fix the response after running XT32 with a Denon 4311. The Onkyo 886 with regular XT did a better job on the subs that the 4311, I had them both at the same time.

Unfortunately I only have Mult-EQ at this time. A new AVR with XT32 is certainly in my future. I eq my two LFE subs as a unit and the stereo subs get eq'ed by Audyssey as part of the L&R front channels. I use the PB13's phase control to align it with the Captivator, then further adjust the phase of the two together as needed using the SMS-1.

XT32 EQ's all the subs as a single source as well, the only difference is it first sets the levels and distance (phase) separately.

Ahh, I see. I could certainly make use of the separate distance and level controls.

That, plus the secret EQ sauce is the value of XT32.

The real time FR display of the SMS-1 (as well as the other nice features you mentioned) is what is cool about the SMS-1.
Waiting for that SMS-2

That is my understanding as well and I believe these are set after the first measurements. I have to wonder why XT32 continues to ping the subs separately for all of the other position measurements and not just do the combined response?

I have 2 SMS-1 but for some reason that doesn't equal a SMS-2

I am hoping they are making a SMS-2, as long as it is not insanely priced I would be in.

Your right in that it is set after the first measurement, it pings sub 1, then sub 2 then a third ping which is the combined response. After the first measurement though it only pings them both at the same time on each consecutive measurement.

The only time to EQ subs separately is when they are being fed a different signals like mojomike has set-up with his SVS subs. When they are being fed the LFE signal then they must be EQ-ed as one since they are getting the same signal.

XT32 really is remarkable at how well it EQ's the subs, it would take hours to duplicate what it does in minutes.
