post #11551 of 18382
somebody asked about "gunshots".

why stop at gunshots when you can have cannon?

http://www.freesound.org/people/man/sounds/14616/

just be sure to turn it down before firing. it appears to be an unclipped wave form preserving much of the spectral content and dynamics of a real cannon shot.

Hey, being a SHO-10 owner myself I can understand.

I had them in my dreams too, but now I have them in my living room biggrin.gif

I put my Sunfire TGA-7401 up for sale on EBay to make room for the Lab Gruppen 10000Q that will be delivered tomorrow. It's gonna be a fun weekend!!!!

Cool man Ill be there some day too. In the mean time I actually really love my SHOs and they give me great joy everynight. But I always want more lol.

Nice on the Lab Gruppen 10000Q wow what a amp!! Curious to hear your input compared to the Sunfire.

Did you list it in the classifieds on AVS? might be worth doing that too.

no problem. I made one correction (speakers in a field have no reflections off walls of course) and the spell check seems to has changed 'haas' effect into 'has' effect.

"So, I'm guessing that acoustic panels on reflection points on the wall and ceiling can help with reflections but not completely eliminate them?"

acoustic panels and dealing with all those "first reflections" is a much bigger problem when working with an omnidirectional radiator than a controlled directivity speaker. most of the cues with respect to imaging are in the 1khz region and up. again, not sure why, it just is. those frequencies are largely controlled by the horn, so acoustic panels don't help much with them. you'll notice that both linkwitz and cowan employ controlled directivity speakers but otherwise have no room treatments. they aren't really necessary.

...

cookgeek, here is a stylized picture of a jtr speaker in horizontal mode. a listener off axis will have a different distance to each woofer. when that distance is 1/2 of a wavelength, the frequency will be completely cancelled out. the closer the woofers can be put together and the lower the crossover point where only the center unit is emitting sound, the less problematic it will be. for the noesis, the cancellation point would be quite far off axis, so unless you were sitting way off to the side and close to the screen, it should be ok, more or less, to run them sideways. the d'appolito arrangement was actually specifically designed for this purpose by the way as a way of putting the off axis cancellation point right on the walls in order minimize reflected energy. turned vertically, it helps minimize ceiling/floor bounce.


That's an excellent narrative on the horizontal verses vertical. I was trying to make that point/issue with questions a few days ago. Thank you...again. smile.gif

Regarding acoustic treatments, we all know that first reflections are bad, especially ones in the vertical (off the ceiling, coffee table, etc). Controlled directivity helps this a lot. Horns can still have issues close to the wall. In the theater I provided a photo of the other day, you may recall that I had to flip the enclosures to gain a bit more distance between the horn and the wall. There was an audible problem created by that first reflection...despite pretty sophisticated acoustic treatments there.

Acoustic treatments are a balancing act. If the room is multi-purpose, it will offten have enough furniture and chachkie stuff around to diffuse the sound without killing off the room. The most common mistake made by folks with dedicated rooms is that they over-absorb the region LTD02 spoke of; >1 KHz. It can happen really quickly in smaller rooms, especially with 1" depth absorption panels...whcih are almost worthless because they only absorb around 1 KHz and above. Finding that balance of absorption where its needed (first reflections) and diffusion where it's needed (randomly and above ear level) is sometimes challenging; takes planning. PMI Limited (Tony Grimani's company) makes 4 ' x 4' panels that have both absorption and diffusion and some depth so that they will actually reach a little below 1 KHz, and they won't break the bank. I've used these a good bit, getting them from Tony. http://www.soundandvision.com/content/pmi-cinepanel-acoustic-treatment-kit

Of course, reverberation time is a player and depends on room volume and frequency. As a broadband target, RT-60 of .25 to about .6 seconds has been the accepted target for designed rooms. Multi-purpose media rooms might be more, and that might well sound fine as long as it's not crazy lively (all glass and concrete/tile). I have one of those big family rooms with high ceiling, but there's enough stuff and mix of floor coverings that it is around .45 seconds. Works out okay.

LTD02, might you like to talk about "Critical Distance?" Seems like that would fit into this discussion nicely when using controlled directivity speakers like JTRs.

what this means is that if two speakers are in a field and playing some music, the imaging will be super tight as there are no reflections. all instruments will appear to be the right size and placed in space properly.

[edited]

put the speakers in a baffle wall and all reflections are killed. imaging is tight. very similar to being in a field. that is why it works so well.

but, if you have to have your speakers out in the room, move them VERY much forward so that the distance from the speaker to the rear wall or the side walls is greater than about 8 feet and the reflections will be heard by your brain as echoes, not combined with the first wavefront into a big foggy image, but a small tight focused image with an echo behind it.

the Allison paper even mentions first best approach is in the baffle wall. cam man mentions that this was thx spec from the beginning and for good reason.

anyway, several different things going on.

Accurate sound reproduction from two loudspeakers in a living room: http://www.youtube.com/watch?v=VC-sxvNzC8I

by linkwitz may be one of the best introductions to some of the key issues that I have ever seen. I have watched it at least 5 times and pick up some nuance of something every time. it is REALLY rich and is very easy to miss big points the first couple times through.

So the "best" case for sound reproduction is outside? Then followed by utilization of a baffle wall? Is that functionally the same as an in-wall speaker? Great link by the way.

should be interesting, not only the clean output but the adjustable input sensitivity should be interesting too. Playing Temple of Thieves - "Pull Me Down" on ITunes 256kbps bit rate (great band by the way if you like Tool you may like them), tonight at 12' and 116dB readout peaks(c weighted fast on my GalaxyCM-140. The sunfire was starting to lose control a little. Pretty dynamic for rock music but the readings were almost always between 108-116 on my readout. I am thinking the LG will be good for about another 6dB. Looking forward to your impressions.

hah. I miss the old days when I put the speakers in the room and they sounded "amazing". No second guessing involved. Now thank to AVS I keep thinking...should I buy measuring gear? How about toe-in? Or different speakers? Or a bigger sub...you get the idea :-)

You might have picked up my uncertainty after visiting such an impressive theater complex to experience Atmos. It shook my confidence in my theater briefly. I came home, popped in a reference BD chapter, and reconfirmed my confindence...by comparing it to a very high professional theater. I was relieved. It wasn't identical, but it communicated the impact and emotion that defines "the cinema experience."

A lot of people gripe these days about the bad quality of commercial theaters/cinemas. If you are lucky enough to have really good ones nearby, you have the opportunity to emulate that experience. I didn't say match its bass its SPL or even refer to the technical other than to say "the experience." Of course, that is the sum of many things...including superb design (acoustic and equipment), installation and calibration. They don't just throw it all in there. It's all on paper (or computer software) first. It is a blueprint for technical achievement. It is an objective approach to achieve from us a very subjective response; emotion, approval, return business. smile.gif Of course, THX made this mandatory, but some theater chains like Harkins take the ball and run very well with it.

Why not let them make the investment in calibration gear? We can go and experience this, and if it really impressed, then go home and compare our experience at home to that at the very well engineered theater. It's a freebie of sorts.

Many people say "I guarantee my home theater surpasses the best commerical cinemas!" Oh yeah? Give me some objective criteria to evaluate that. Sounds all subjective to me. And if that is exactly what has made you happy, then fine. But those folks need to add a disclaimer. "I guarantee my home theater sounds better than any commercial theater...to me." wink.gif

I've often told people that from the time I first throw the switch on the camera the first day, until the movie's release, there is total chaos in many ways. Although it seems that way, there is actually a rather defined set of standards and protocols followed through the process. The goal is for the end product to be standardized/consistent. The theater is the last step and the wild card, but THX recurruing certification or just consciensious theater chains help us bring a pretty standardized experience to the public. They won't be identical, but if we can communicate the experience, we have won. I think that is a worthy goal for home theaters, too. Just my $.02 worth. redface.gif

Hey man Ive read through a few of your posts and I really like the way you think. I respect your audio prowess as well. I totally agree about having a good sounding cinema near by where you can try to imulate the "experience" of the show. Thats what I try to do and as Paul Klipsch has said, use it to recalibrate your ears. I can recreate the movie experience pretty well especially after my absorption panels.

I also enjoyed your Atmos review in the Klipsch thread.

Damn...I get on here tonight and see 50+ posts to read. I thought for sure someone had spoken negatively about the almighty Noesis. smile.gif

And what the hell is it with all of the Disney DVDs and Blurays being so much more expensive than most other movies than have been out for several years? Decided to pass on Toy Story 2 at $20 for DVD and $25 for BluRay. I liked the Croods in the theater when I saw it with the kids so I'll probably pick that up, even at $26. And the Open Range DVD while I'm at it. Another Disney film I really liked was Over the Hedge...that **** was hilarious with Bruce Willis (unfortunately no guns with unlimited rounds) handling voice for the lead character.

So how was Oblivion as a movie? Any good or primarily another good AV experience?

LT, thanks for the explanation. I guess that explains why moving around on my bed made not much difference. I guess unless there's a very wide couch placed very near to the speakers, the Noesis are good to go laying down as center channel duty. Unfortunately, they are rather large for most living halls.. mine covers the last 2 inches of my tv right now but it's only temp and will be moved to behind an AT screen in a few month's time.

Thanks for the link. I will definitely check it out once i got my OS hooked up.

BTW: I started a thread on building a mid bass unit to complement my noesis.. anyone who have experience here please give me some input. It'll be greatly appreciated.

By the way, I just came across this post about Speaker Burn-In and thought it would be pertinent to this thread as some have stated they feel their Noesis speakers have changed sound slightly and others have said it's your ears getting used to the sonic signature. My guess is it is likely both.

Gee, thank you for the kind words. I don't know about prowess, though. redface.gif I stay close to guys who really know their stuff, and ask a lot of questions (over the last decade). I've also been hanging out here since February 2000. smile.gif

I would certainly regard Paul Klipsch as an excellent source! "Recalibrate" is a good way to put it. Another is what a lot of us in cinematography say: "Plagerism is the sincerest form of flattery." wink.gif We see something we like and go to work figuring out how they did it. In HT, since the pro and home environments are so different in scale, our task to emulate the big pro room is not easy. Sometimes the best we can do is do the basics right and hope to emulate the experience rather than duplicate the environment.

You got that right Cam Man. They are indeed very different environments. You really do gotta find what works and what you like and use that as a reference. Especially with audio it seems.

Hey guys, we're talking a lot of acoustics and speaker positions and stuff on here. Over on the AVS Radio area, they have a series with Anthony Grimiani underway. Acoustics 101 & 102. You may remember that a couple of pages back me talking about Tony teaching the heavy blocks in the THX training about 10 years ago. Excellent education to be had there. Enjoy.

From what i know, I think the Noesis 212s are replacing the tripple 12s and the Noesis 228s are replacing the T8s...

At least if I were to make buying decisions, i would go that route... I have the Single 8s and I can tell you the difference between that and the Noesis 212s are astounding (some here might not agree). And the T8s uses the exact same coaxials of the single 8s... I am going to assume the 228s will also be a huge step up from the tripple 8s in terms of SQ, not necessarily SPLs...

And if you can afford it, go with the 212s and never look back. I doubt i'll ever need to upgrade from there...

Those are pretty much my impressions too. And in my experience at those volumes the control is actually lost far before your brain realizes it. The actual loss of control by the amp likely started 3-6 dB before that point. Only an A/B with a clean signal would highlight that reality. Clipping is insidious.

The horn design in the 212 & 228 are an addition to the the JTR Speaker arsenal not a replacement. The horn design has a limited dispersion pattern so it is not the best option for all situations. The Triple 8 is a 3-way design with the CD attached to a fitted coaxial midrange making it a great option for LCR and side/ rear surrounds . The 228 is a 2-way design with the CD attached to a 60/40 horn making it nice for LCR speakers but not so much for surrounds unless one truly only cares about the LP while seated. The Triple 12 has more to offer than the either the T8 or the 228 and at $1599 is $600 less expensive then the 212 but is not limited to placement like the 212.
Since speaker designs are a series of compromises and trade offs JTR and its customers will benefit from offering both the Coaxial fitted midrange 3-way Triple series and the Noesis horn design. The Triple 8 offers more then the Single 8 for the $300 price difference. The triple 8 comes in the LP model (50lbs) and can be wall mounted.
Why offer either or when Jeff can do both.wink.gif

Ah... sounds like a plan then. Which means I made the right decision in going with the single 8s for surround duty...

I wonder how many people nowadays opt for either t8 and t12 vs the Noesis? Just out of curiosity...
post #11574 of 18382
GOT THE ORBIT SHIFTER HOOKED UP!!!

Books ARE flying... haha.. well, maybe not... but one of my bottles on a shelve did shake loose and fell to the ground.

OK, initial assessment.

IT HAS TONS OF OUTPUT... way more than BOTH my HSU's combined. It might actually equate to 8 HSUs ULS 15s in terms of output... (if i had to make a guess).

But a caveat. I prefer using my 2 HSU's for music vs the OS... The sealed subs are cleaner and seems to blend nicely with the sealed Noesis.

I don't know yet why... there are still too many variables to call this.

1) the SUB placement. The OS is now beside my bed and I don't like it there.. crossed at 80hz (which is the lowest my receiver can do and the OS doens't come with it's own Low Pass Knob like the HSUs where I can adjust the frequency range.), I can totally locate all the sounds and it's bugging me. I need to move it to the front but there's limited placement in my current room. Not sure how to fit it there...

2) I'll have to get my processor working (currently either my cables are not done correctly or the processor i bought has problems, signals not getting thru), and then cross the sub at maybe 60hz.. not 80hz...

3) What gain do you guys use for your Orbit Shifter? It was really confusing. The higher the number, the lower the gain.. it's complete opposite from my HSUs... It took me a while to realize that. When set at 1db, it's super loud... is this normal or is there a design flaw in the speakerpower amp??? Currently I have set it at 12, which totally overwhelms the Noesis...

Ok, that's it for now.. i think i might be deaf... i can literally feel the air compress in my room.. might not be too good for my inner ear... without an SPL meter, i might actually be doing some permanent damage...

but.. my bed is vibrating like i actually inserted a coin in...

Those numbers have plummeted since the introduction of the 212 & 228. I would imagine there will be a leveling off period once the Newness of the 228 wears off. If and when Jeff introduces an upgrade for the current T8 and T12 owners the conversation will change to that for a while but all JTR speakers and subs compliment each other so well that mixing and matching the 2 designs will allow for all around better performance for our HT needs.smile.gif

I have an ashley protea 4in 8 out. I can set crossover there. Is that the same as a minidsp? What freq should I cross the os at? Right now it's at 80 crossed from my receiver sub out but I think it's too high. The problem is I can't seem to get a signal thru my Ashley processor. It's either the cables aren't done right or the ashley is defective

BTW: what 'gain' level do you guys set for your OS when used with a regular home receiver? I have currently set it at 12 (or is it -12db).

That will be different for each room. Either use the auto calibration to set gain levels or use a SPL meter and manually set them. Many (probably most) bump up the LFE level for movies.

You were referring to the gain knob on the amp. Try it at 9:00AM. Calibrate system and then check levels. Adjust up or down as needed to get sub close to 0db level. in the AVR or Prepro.

The OS amp is powerful. Divide the volume or gain knob into 20 different clicks or settings. Starting at the lowest setting or all the way down, 1 to 4 clicks from being turned off is usually over the 75 - 85 dbs.
Basically the gain knob setting from just barely on to about 25% of the total power available will be all you can use. Halfway up would probably be too much.

I can confirm that on my S2 subs (same amp used as the OS I believe), I only have the volume at about 20%. THe first day I turned it on it was around 50% and the roof almost came off my house...just saying :-)
