MKtheater Posted June 2, 2015 Report Share Posted June 2, 2015 Hey Adam, I fixed the shaking projector syndrome. I had to wedge a piece of Styrofoam or hard foam in between the lens and in between the projector and ceiling. Sometimes the writing will vibrate but my favorite is during a single digit burst the screen will ripple. Without the foam my screen looked like a wave of water going by, not it just shudders a little. Link to comment Share on other sites More sharing options...
Bossobass Dave Posted June 3, 2015 Report Share Posted June 3, 2015 Hahahaha Dave actually sent me that pic with a Raptor stack in the foreground! :lol: http://bossobass.com/Bossobass.com/Technical%202.html Scroll down to the Raptor specs. It's called the Vortex house. Always loved it. Perfect illustration for what others think of our hobby. Link to comment Share on other sites More sharing options...

Yah I saw someone else did that too but my whole pj shakes cuz its small and weighs like 10lbs hence a lot easier to shake. I'll try it though since I still have some wedge foam left. Hahaha that's the one. That would definitely be your neighbor coming over if you had 3 or 4 systems running. "Crazy ass Dave imploded his room! Now I don't need this gun."(cuz that's clearly what's in his hand) Link to comment Share on other sites More sharing options...
maxmercy Posted June 4, 2015 Report Share Posted June 4, 2015 Ya know a lot of guys on here have some pretty capable systems. I do wonder at what levels you would start to damage your house. There is no way in hell I would run 3 Raptor systems. It already sounds horrible in the rest of the house when my one system is turned up. Hell the BB in the living room makes my house sound bad haha. And the lower you go... Do NOT underestimate the power of resonance. Google "Tacoma Narrows Bridge". IIRC, it didn't take much windspeed, just the right windspeed to cause it. JSS Link to comment Share on other sites More sharing options...

Diogenes Posted June 9, 2015 Report Share Posted June 9, 2015 I have a few songs from the Telatc series of CD's. 1812 Tchaikovsky and a few others. I believe the CD states that it has 7hz canon blasts. BUT the trac is about 40mb. Would be fun to see a cap of that:) From the 25th Anniversary Classical Sampler: First set of cannons: Second Set: Cannon spectrum: What it looked like back in the day on vinyl: No wonder it got such a reputation, most stylii would skip right out of that and those that could play it would distort and lose the information in the rumble filters.

SME Posted June 9, 2015 Report Share Posted June 9, 2015 Wow, that picture of the vinyl is awesome! I was kinda of hoping the 1812 canons had a bit more ULF bass because I find them a bit underwhelming as it is on my 16 Hz system. One day I did hear them from the opposite side of my house (part of the same open space) and noticed a lot more low end than I had before. I suspect that the upper bass content masks a lot of the bottom end on this recording at my MLP. At the rear of the house, the bottom end is stronger relative to the mid bass. That said, are the different releases created equal? The one I have is a hi-res digital download that supposedly came from the SACD master.

chrapladm Posted June 9, 2015 Report Share Posted June 9, 2015 I dont think they are ALL equal in quality or ULF. BUT I do believe I also have a digitally downloaded version of 1812 direct from Telarc. Link to comment Share on other sites More sharing options...

Not my own, of course, but I too have always found that to be an awesome picture. Right in the center you can see the spot that made the Telarc 1812 legendary: that right angle jog that pops all but the most complaint and best tracking cartridges out of the groove. I understand that being able to get past that one spot made for worthy bragging rights among audiophiles back in the day (and still does for that matter). It's never really been about the low frequency extension with this recording, it was the broad spectrum dynamics that's done so much with the reputation. (Turn it up so the orchestra is loud and...BLAM!! BLAM!! BLAAMM!!! System killer there. Window killer, too, as I understand that particular performance blew out several windows of one of the campus buildings with the percussion.) It's really impressive to consider that they managed this much with the analog recording equipment of the day, surely taking all the tricks and skills they could bring to bear, and had the guts to put it out as was without filtering and compressing everything to hell and back like everybody else did to suit the constraints of the medium. I've heard that later vinyl pressings reduced the modulation some to be playable to a broader audience. (Telarc wasn't always about ultimate fidelity; they did put out cassettes, afterall.) From what I've read, though, the digital formats received the original treatment of 1812, full dynamics and everything. Link to comment Share on other sites More sharing options...
SME Posted June 11, 2015 Report Share Posted June 11, 2015 The version I have is this one: http://www.amazon.com/Tchaikovsky-Overture-Kunzel-Cincinnati-Multichannel/dp/B00005AVNH Except mine was converted to 24-bit 88.2 kHz for digital download. Playback level is something like +5 from theatrical reference or higher. It is definitely the most dynamic published music recording I own. The only published music in the same league that I own is "Best of Kodo", which is also brutal test of a system, particularly with regard to mid and upper bass. It'll destroy your mains if you let it. I play it at least +3 from theatrical reference, and it should probably be played a bit higher still. I've heard them play in real life in a very well designed concert hall, and the chest pounding was pretty epic. Then there's the (unpublished) Danley recordings, for which, I don't have any idea what playback level is appropriate. About +7 is as high as I'm brave enough to take them. I loaded the later fireworks recording in Audacity and noticed it really punishes the mains between 100-200 Hz. No wonder if slams so nicely. Then there's the Harley recording, which gets the same treatment and seems to impress my guests more than the fireworks. I can't blame them. 90 Hz at pants flat levels is pretty damn wicked. When I played the recording cranked up, I commented to my wife, "so this is what the appeal of owning a Harley motorcycle is". Yup. Link to comment Share on other sites More sharing options...

chrapladm Posted June 11, 2015 Report Share Posted June 11, 2015 Funny.....as I have all of those tracs that you mentioned. I have all 3 of the different covered CD's from Telarc, few different CD's from Kodo, and the DSL's tracks. Also liked Bosso's short intro he made and countless other ULF tracks. Nothing compares to a great symphony for my enjoyment but bass tunnel slowed was quite nice. Bosso try this test and see how it feels. https://www.youtube.com/watch?v=ZgcDxm1HI60 You know....... when your trying to make sure you have ever rattle gone from your HT listen to this track.

BeastAudio Posted June 11, 2015 Report Share Posted June 11, 2015 More on that star trek scene..... I ran through that and then the Capt 'Merica bubblegum dispenser scene last night. Ugh, yea, I felt the LFE in my room......I even power cycled the Crest on the CA scene. WHA?!?!? Yea, shut the bugger down! On a scene that most people don't even know exists..... I think Paul is working on getting that one capped for everyone to see. It aint on the regular thread, I will tell you that much Man, Dave's floor ripple is one for the books to say the least. The experience you get with the ultra low stuff down below 10hz is unreal. I will make sure my next home has a 6hz tuned room....haha! I spent some time admiring the raptor III systems Dave had brought up and installed for the g2g that day. I know others have already said it, but the craftsmanship that Dave and Paul have put into these enclosures has no parallel. The attention to detail design choices made make the raptors happy in just about any room one would want to put them in. The bamboo was just freakin' gorgeous. If I didn't have a capable setup already, Dave would have waved bye to me with a nice check in his other hand It's not to say I won't be doing a lil' sumpin er another here in the near future anyways :wink wink: Anyways, I could spend months in my garage attempting to get that nice of a finish, kudos there! To top all that off, the a14-k is an absolute MONSTER.....That amp was doing this to those subs that was just downright illegal, but the good news is, the subs took it all in stride 16-15's? Check please! Content: All the good ones Pac Rim, as we all now isn't the deepest, but man is it a bass journey that literally leaves you aching from the pummeling. It was merely a good warm up for what came next.... we delved into the meaty section of ULF: TIH, ST ship flip scene, the CATWS bubble gum scene, Oz ( I have to go buy this one now). The fireworks on Oz literally had me flying out of my seat as I thought the system was still muted but it wasn't.....holy cow! Really fun, family friendly demo scene that packs a punch. The other tracks were just silly. I already mentioned the floor resonance. It's just something you have to experience. I am moving my theater up to the living room as we speak to try and get on that Haha. (Not really) Next up we did some output monsters, Interstellar stuck out here. My god I was having a little trouble seeing. I know this sounds stupid, but I love when it gets to that point.... Link to comment Share on other sites More sharing options...

LOL I usually just use pure raw sine sweeps to test for rattles. It sounds like there's not much more than that to this one. My setup is pretty low on rattles above 20 Hz, unless the SPL gets real high. I did notice some port noise on this one at around 15 Hz ... from the air moving through the gap at the bottom of the door that connects my house to my garage. I will have to try to get that opening sealed some day. Link to comment Share on other sites More sharing options...

Good stuff! Yah I haven't watched that yetin my room, but just doing that scene made me remember how amazing that soundtrack is. The A/V in that movie is top 3. Even with a cheap ass pj on a 165" screen it looked amazing. Hopefully one day 4K will be reasonably priced and available. Link to comment Share on other sites More sharing options...

chrapladm Posted June 14, 2015 Report Share Posted June 14, 2015 I figured someone might. I tried that years ago and just watched the woofer move to roughly its full capacity. Was quite fun although my other THT sub was not liking it. lol Link to comment Share on other sites More sharing options...
