  1. They are pretty big! I can tell you in my room lots of bass treatments made the bass is very very tactile (e.g. waterfall plots that decay under 300 ms down to ~20Hz at 40dB down from peak). This combined with a clean ETC/impulse response (which fixes imaging) are the most important measurements I've found, and made the biggest difference for me. I've had huge gains in sound (imaging and tactile bass) by making these two plots look as clean as possible.
  2. Here are some impulse response plots of my old leather high back chair versus a new low back fabric chair (less than 37" tall) I bought at La-Z-Boy (brick and mortor only) for half off. I initially ordered two, but since they are more than half off ($399 regularly $829), I ordered two more so guests have a place to set. They are the La-Z-Boy Designer series too (not the cheaper stuff), with thick velvety fabric and nice stiff padding. By the time I sell my Palliser chairs I bought off craigslist, I won't be out too much more and will have brand new chairs. Although things sounded very very good before, it seems leather is too reflective for a picky person like me (who is also obsessed with plots and measurements). The high back was also messing things up. After I rerun Dirac Live Full (Emotiva XMC-1 version), the results should look even better.
  3. What an improvement for very little money after I sell my palliser leather chairs on craigslist (which is where I bought them so I'm not losing much)! I need to rerun Dirac, but the red plot speaks for itself. No more peak at near 690 microseconds and the plot looks cleaner over all even without Dirac.
  4. Maybe... I'm seeing a high peak at 690 microseconds on my ETC plot due to my current chairs. I'm not sure if fixing it will make a perceivable difference or not (due to the time it takes for my brain to actually process a sound). System sounds great now though!
  5. It reclines, speakers are optional though
  6. http://www.la-z-boy.com/p/charlotte-high-leg-recliner/_/R-028931 Comes in brown or burgundy for $399 + tax (ends this weekend). Of course you can go custom for $400 more, but I opted for the black friday special. My ears are just above the back and the chair is well padded too. Seems like a great audiophile chair, especially if you are ultra anal and want to have your impulse response plot look a little cleaner. It will be interesting to compare REW measurements versus my leather chair with a very high back. Made in the US, and the construction looks good given it's price. PS: I think this may be instore only at your nearest La-Z-Boy store.
  7. I agree that THX may recommend the two foot thing, but this is not what Dolby shows in the figure on their site. What THX shows on their website is a dipole looking sound field two feet above ear level (not what I'd want). I'd much rather have all mid-ranges at ear level all the way around. There are a lot of on-the-stage audio mixes where this is very beneficial for the best possible imaging too. THX is giving recommendations so that the sound is spread throughout a room for multiple listeners. Many of us with smaller rooms only want the best sound in one or two seats. The truth is unless you have a separate room for music listening trying to cater to all seats in a home theater is going to lead to less accurate imaging and a sacrifice of system performance. I've heard ChrisA's system, and this is what convinced me of this fact. I think we can agree there are different schools of thought here. I personally believe in controlling directivity and using acoustic panels (for all channels) to ensure an excellent ETC/impulse response plot as I've found it gives me the best imaging (for all channels). I agree in the Dolby Pro-Logic days this is what surround speakers were truly met to be above ear height, but many of us critical listeners are into these multi-channel music recordings from 2002 on.

    What I Got Today!

    My used Emotiva XMC-1 shipped from Puerto Rico and arrived last week, been enjoying it ever since! http://emotiva.com/products/pres-and-pros/xmc-1 I got a fantastic deal on it, so I figured I'd take a chance of not liking it, but this is the best sounding preamp I've ever had! I immediately noticed a difference in clarity as it's differential design matches well with my ATI AT2007 differential 7 channel amp even before running Dirac. Also it seems door slams/punches sound a bit more real (to where they actually startle you). Although, all these differences are small compared to the Marantz AV8801, I think discerning listeners would hear them. Overall, the XMC-1 is a great unit for the money. The noise floor on this thing is incredibly low and measurements compare with pre/pros costing many times more: http://hometheaterhifi.com/reviews/receiver-processor/processors/emotiva-xmc-1-processor-review/ The only complaint I have is Dirac Live Full (Emotiva version) can't really compare to the EQ job Audyssey Pro was doing, especially since I was using SubEQ HT before (which pings the subs separately to set level and phase, and then calibrates them together). I'm going to try a few things to improve Dirac's measurements. I think they sound great, except the bass isn't as nice as what I got used to after having SubEQ HT. I may just use REW to upload filters to the XMC-1 (which is a new feature they added in firmware 3.0). My Dirac Live Full (Emotiva version) vs. Audyssey Pro measurement comparison is below. These measurements were taken as objectively as possible, and the Audyssey Pro calibration was done for only one seat as was the Dirac (comparing apples to apples). http://www.avsforum.com/forum/90-receivers-amps-processors/1617090-emotiva-xmc-1-owners-only-thread-143.html#post38951553

    What I Got Today!

    Thanks! I posted video tutorials and modules/scripts to set up what I showed you (voice control under Android) on my YouTube channel: https://www.youtube.com/channel/UC6fLTEmRoGam7B5VoKazC9A I don't know if I'll keep doing the videos and posting my work, but I've been trying to post something every week; not enough people watching them versus the time it takes to record them. However, if they perpetually earn me $10/month it may be worth putting more up there. The KODI/XBMC video is pretty cool; I have it integrated into my house very nicely (caller id, doorbell pictures, auto library import, voice control, etc...). The KODI module + some scripts can do cool things for a setup like yours such as automatically set a parametric equalizer based on what library item (e.g. song) is playing, etc... I have the KODI module setup to automatically move my anamorphic lens sled in/out when 2.35:1 video content is played. Pretty neat.

  11. The speakers aren't too bad either Klipsch sure knows how to do product placement; what can I say?
  12. Looks like it based on the scaling. Pretty good show so far too, although we both know the speakers are better!

    What I Got Today!

    "Bought" this thing in the Windows 10 App Store. OK, it's an app I built and put on there, but Windows still made me pay to download it! Quick Demo What's Required? 1. Setup Motorola Premise Home Control (free home automation software) on a windows PC. This is not bloatware, Motorola used to sell the software for around $1000, but made it free when they discontinued support. There's an online http://cocoontech.com/forums/forum/51-premise-home-control/'>support forum and a [url=http://cocoontech.com/forums/page/home-automation-software/_/premise-r3]wiki[/url] though! Plus there's an SDK, so new technologies are added by tech savvy users. 2. Link whatever you want to control to your Premise server this can be lighting, HVAC, Security, A/V, anything that can be hooked somehow to your PC or network (KODI/XBMC, z-wave, insteon, radiora, upb, global cache... hundreds of supported devices and technologies). 3. Install and setup my SpeechParser module (by watching tutorial #7.x on my YouTube channel). 4. Install my Premise Control Home with Cortana app to control your home hands free by saying "Hey Cortana...Control Home...[insert command here]. Key Features Note the command phrase is not order dependent and works with synonyms too; you can even ask questions about your home (such as what is the brightness in the living room, when was the front door last opened, etc...). You DO NOT need to program a sentence for each device/property for this to work with your voice. Just give Premise the room names (regular expressions are supported, but optional), and my free Premise SpeechParser module does all the work of figuring out what you want based on what devices you have automated in a particular room! App uses a background Cortana voice service that is enabled once you open and setup the main app, so it works when things like KODI are in the foreground! App is compiled as a "Universal Windows Platform" (UWP) app, so it will work with Windows 10, Windows Phone 10, and maybe the Xbox One in 2016!
  14. Minority Report Season 1 Pilot:
  15. Too far from me, but this is the best deal I've seen. The bookshelve speakers alone are ~$2000/pair dealer cost, and the palladium sub is included. Hopefully the ad is legit...? http://up.craigslist.org/ele/5115910264.html
  16. Please go back and read my post. No where did I say a Jubilee can't be as good or maybe even beat a P-39f?!? I heard the Jubilee's with the TAD drivers and was ready to buy, but didn't have the space and no way were they going in my living room/great room (said my wife). I'm glad for you that you have a 20 foot wide room or whatever to accommodate them, some folks don't. Like I said, I wanted a Jubilee and couldn't fit one, I thought my post was clear on this?!? I stand by my statement about the khorns though. The La Scala II's have the same drivers and horns on top as the Khorns. In the same room, with the same equipment, with the speakers in the same spot, even using Audyssey pro kit to level the response to be flat, the P-39f's beat them. You are welcome to your opinion, but I've lived with both and listened to both for hundreds of hours, so... The difference in clarity is especially noticeable at low volumes and easy to hear. I have an MS in EE so I'm pretty objective. I don't spout nonsense after hearing speakers for one session in a non-ideal environment. I do believe if I'd have changed the compression drivers and/or added a larger horn, and then also added an active crossover, the LS II's I sold could have sounded very close, if not as great. I got a good deal on the used P-39f's though and wanted 7 channels and plan to add more channels (something I couldn't do with heritage stuff due to space limitations). Comparing out of the box products, the P-39f's sound more real and have additional clarity I didn't hear from the LS II's. Also, who wants speakers where the midrange is so close to the floor (I'm pretty sure the khorns are taller though)? I like having my midrange horn at ear height. Folks really need to try speakers in their home for a few weeks (in place of their former speakers) before attempting to compare them. One absolutely needs to have well recorded test tracks to compare with, that they've heard hundreds of times too. Listening to tracks a demonstrator or salesman picks isn't going to cut it. You must be intimately familiar with whatever tracks you are using for the comparison. I'd like to know how many of these users you speak of have actually owned the speakers they're comparing. I know the guy who ran the klipsch corner website still loves his P-39f's, just saying I'm not alone... Sorry, but you are the first person that I have ever hear say they thought the PF-39 sounds better than the Klipschorn, let alone Jubilee. That not only includes all of those present at the Hope demonstration, but other friends I have that have had a similar Demo at Indy... Roger
  17. I tend to agree. I've seen pictures of the demo and the Khorns likely had the best spot in the room as far as corner loading is concerned. We all know moving a speaker 1 foot can greatly impact it's low end, reflections and impulse response. The most scientific way to compare speakers would be with conveyer belts like harmon-kardon does in their double blind setup; with the speakers hid behind curtains and tested in the same room location, level match (very important), fast control switching, acoustically treated room, etc... Having lived with the La Scala II's for a long time, and then the P-39f's for a long time, I can tell you the P-39f's have more detail and sound more real to me (and my wife too) in my room by a noticeable margin. I'm not going to compare the low-end, but the Khorns have the same horns in the upper range as the La Scala II's, so I'd expect no difference in the high-end. I'm not saying you couldn't make the LS II's and Khorns sound better by time aligning the horns and swapping out the drivers. The La Scala II's just never produced sound that was as real and clear the way they come from the factory. They had a great sound to them though. I heard the Jubilee's with TAD drivers, and they did have a very real and clear sound. I just couldn't fit them in my home, and used TAD drivers pushed them higher than what I paid for the used P-39f's.
  18. The best you can do is scan the pictures and have a printing company print them on canvas. Then you can build your treatments and wrap the front and side with the fabric. Too bad you have such an awesome system, but don't have bass traps or permission to use the danleys. Bass traps made a big difference for my system. Same with room treatments. How much are you wanting for the danleys, are you looking to sell?

    Priceless

    Why is this information out in the media in the first place? Now all terrorists know we read their social media. It would have been much smarter not to mention why or how we obtained certain information that lead to the air force's actions. Sucks when politics get in the way of intelligent decision making.
  20. ChrisA is very knowledgeable, you're definitely on the right track with him involved. I'm sure you know this, but frequency response is only a small part of having a great sounding system. I listened to ChrisA and this thread, adding lots of bass traps and treatments, and my system is now the best I've heard.
  21. It seems more places offering these minor surgeries would be a good thing for the consumer as it should bring the cost down. With regard to the other comment, I don't know about Obama being at fault, it seems any conservative should love letting the free market do more things with less regulation. Optometrists probably spend years more in school studying just human eyes, where as someone like an ophthalmologist who has to go through full fledged medical school like an MD.
  22. I have no doubt you could get $800 if you posted it on ebay. They are very rare subs, but a great value. I have two, but it took me a long time to find a second one.
  23. I think it'd be neat to measure THD of the two subs (maybe even outdoors), after using REW to level match them. Have you tried REW, a calibrated USB mic, and an SPL meter? What I've learned is so much of a sub's performance has to do with things like acoustical treatments, using a pair (or more) to help smooth the in room response, etc. I finally got my subs to decay in less than 240ms all the way to 24 Hz (40dB down from 105dB using the waterfall plot in REW). Quick decay time like that is crucial if you want tight bass. Of course ensuring the frequency response is flat is important too. It'd suck to have a big dip in the chest thump region. Any ways, if you follow this thread and add another RSW-15, you'll have an awesome system for only ~$800 more, plus maybe another $80 for a calibrated mic, and some bass traps.
  24. I'm still enjoying the 39's I bought from Billy or I'd buy these. These are by far the best sounding speakers I've heard or owned. Much better than the La Scala II's I sold.
  25. Read through the first few posts here: http://www.avsforum.com/forum/91-audio-theory-setup-chat/1449924-simplified-rew-setup-use-usb-mic-hdmi-connection-including-measurement-techniques-how-interpret-graphs.html REW is probably the best choice given there are several support forums and the software receives improvements. Most use a calibrated mini dsp usb mic or this one: http://cross-spectrum.com/measurement/calibrated_umm6.html
