Gary Forbes Thanks so much for your comment. Look forward to talking with you please do get in touch any time and we wish you all the best. From the team at HTE

.....................and?

Hi Steve, so sorry we get so many comments and yours slipped through the gaps. Good luck with your project. We are currently managing several projects in the US and other countries, If we can help you at all please reach out to use via our website. Hometheatreengineering.com and wow 200” IMAX thats going to take a beast of a projector to reach any kind of HDR levels..!

@@HomeTheatreEngineering The Projector is only going to be either an LG 4K Laser Projector or an Epson 4K that can produce up to an 200 inch 16:9 Image. What I meant by an IMAX Theater was creating an IMAX Themed Theater. I was thinking about going with an Old Classic Movie Themed Room. Other iterations on a Theme was as follows. 1. Knight Rider Theme. 2. Airwolf Theme 3. MacGyver. 4. Miami Vice. And or a Classic Tarzan Theme or a Classic Sherlock Holmes Theme. Using IMAX intros in front of every movie.

@@HomeTheatreEngineering Here’s what I meant by IMAX Themed Movie Room. I was going to add these before I played any Movies. kzfaq.info/get/bejne/pJt4lbRo26nadI0.html

@@vestel777 ok I get it. Sadly the movie industry makes life hard for us 16:9, 2.35, 2.37,2.39, IMAX, 2:1 choose your poison !! If you are already working with a lens then ultimately you have opted for widescreen as primary. The IMAX format will play but obviously with black bars left and right and ironically a lot of these imax themes are actually in 16:9. If you haven’t set up anything then possibly the format to go with might be 2:1 it kind of gives you everything but also with black bars almost all the time somewhere. So how does the lens handle that well again it depends on the anamorphic capabilities within your projector. If the material is 16:9 then fine if anything else other than scope there will be some variations in screen fit. I hope that helps

We serve clients not only in Melbourne but all around the world. We start with photos and measurements and details of your own requirements and then design the room for you and send you the result. Once you have the completed design we can help you find someone local to install and set it up and often we then come over and calibrate the end result. Contact us directly for more information.

Thanks for your comment on bass traps. I disagree with your comment on 2 subs. Modal analysis shows marked improvement with 4. I certainly have achieved superior results with 4 and this seems to be supported by Harman Labs research. A good read is Sound Reproduction By Floyd Toole.

Carlos, you shouldn’t make declarations so easily disproven. Don’t read one article or watch one KZfaq video and think you’re an expert. Research room modes and standing waves. While multiple subs doesn’t guarantee perfectly smooth sound without measuring and calibration, with a bit of work, four subs can even out response over a broader area of seats. #Science

@@scottwallace1 I have to agree with scottwallace here. The evidence is stacked against you Carlos. Also I am personally not a fan of “extremely large subs” especially in smaller rooms. They are harder to manage and more like a blunt weapon than a finely tuned instrument. The aim is not power (to an extent) but detail and precision. The physics of large subs challenges this to some degree

Yes of course we can. We have a professional design service please contact us through our website hometheatreengineering.com

For design we use several tools from REW to CARA plus tools built into the HAA calibration software package.

Hi I am not sure are you responding to a comment in the video or some other comment? It’s great that you do those things but they should be standard as a minimum for all installations. I don’t know that I would call basic setup as recommended in the user manual calibration at all but regardless it’s good that it’s getting done we see a lot of jobs where that’s not the case too. I’m not sure about free standing speakers, these are definitely not a good choice for theatre for a stack of reasons. It depends on design but if you are running an AVR and crossing over at 80hz then you aren’t using the full range of free standing speakers. If you are using full range you are using a lot of power and reducing dynamic range and headroom due to the demand of the woofers in the freestanding speakers. Finally these are now functioning as subwoofers and often are not in a great location with regard to room modes and you now have to configure tone align and phase manage those along with all other subs. This is often more trouble than its worth which is why good home cinemas (and high end cinemas like DTS Europe etc) don’t use towers or full range free standing speakers. It’s is often done but it is far from optimal depending on the design and spec. Hope that makes sense. Certainly though in our region given the exposure we have to other work I stand by my statement that our industry doesn’t finish. It’s good to know that companies like yours are out there doing the right thing. That’s a win for the customer.

@@HomeTheatreEngineering Hi. First, lead with positive…good to see, read, and hear about companies in our industry who care and who put the work in. Now, ‘freestanding’ speakers…not sure where in that you necessarily equate that to mean full range towers, but one thing at a time… Freestanding means not in-wall, on wall, or in-ceiling. It means speakers that are not inherently tethered to a boundary. This could mean full range towers, but it doesn’t have to mean that. And a home theater is a decidedly different creature than a commercial cinema. Commercial cinemas are bound by physics to use transducers for mid and high frequencies that can efficiently broadcast to a large auditorium without constantly redlining it. Hence, compression drivers. And in order to have sufficient bass for a large space, you need multiple bass drivers placed in spots that energize the room evenly. Given this, the main speakers are crossed over fairly high (80Hz or so) so as to not muddy the waters should those speaker positions prove to be undesirable as low frequency transducer locations. These are logistics that are not necessarily a part of a high end home cinema, optimized for one or very few viewers/listeners. And while residential size rooms certainly have their own room mode issues, it is also true that the very best music reproduction is done with a speaker that can reproduce the full frequency range and dynamic envelope of a recording so as to preserve all of the delicate harmonics and help ensure a cohesion that is exceedingly difficult to pull off with a sub-sat system. And so, for a home cinema customer that also places a high priority on stereo music reproduction (still a large percentage of our clientele), a carefully setup system using full range speakers (still crossed over in virtually all cases, just much lower than 80Hz), with an identical vertical center when possible or the largest horizontal center channel speaker when not, can provide phenomenal stereo reproduction, but still fantastic multichannel reproduction. Energizing a residential sized room with real bass from multiple main speakers and from well set up subs can be an amazing experience. Key of course, is finding where those larger main speakers may be exciting room modes and crossover and room correct as necessary for proper integration and smooth playback. But, point being, a full range speaker crossed over properly and mated to a subwoofer is a far more powerful and engaging experience than a bass limited main speaker that requires a subwoofer. The latter is always given away by a gap between the effective low point of the main speakers and where the sub picks up the slack while the former’s inherent character is such that that transition is much more disguised by the smoother handoff to the sub from an already highly competent fuller range main speaker.

@@scottwallace1 I agree with some of what you say. But totally disagree with your statement that “it is true that the very best music reproduction is done with a speaker that can reproduce the full frequency range….” Etc. We have been able tp prove time and again this is not the case for several reasons. 1) using a subwoofer if properly integrated is no different to using a subwoofer or bass driver in the one speaker housing. 2) you are making no allowance whatsoever for the extra energy consumed by the bass driver in that full range system. Many people still use all in one AVR’s and these share power. Using full range speakers with these robs the system of headroom and dynamics. Many of the brands we use are designed and built from the ground up to be crossed over at 80Hz, Procella is an immediate example. Finally if using full range speakers a lot of phase cancellation can occur dependant on the room dimensions and speaker locations. It is more critical to energize a room evenly in a small space than a larger space, unless you are dealing with 1 seat. The very physics of a commercial cinema means that most have lengths and widths that eliminate a significant number of modal issues. In short our approach is not to use full range speakers for the reasons above. We do however put massive time and effort into this to ensure the detail and cohesion is maintained and that takes work. I am not sure about the reason for your point as to the definition of freestanding speakers but I agree. Our aim is to provide and equally good stereo or multichannel experience in all of our rooms. As it happens we also own on of Australia’s leading 2 channel businesses and we make it a point of ensuring the standards we apply to our 2 channel/audiophile clients applies to our Home Theatre Clients. Personally I do not accept that products are better for music or for Cinema. This is an unfortunate development in our industry, the goal should always be “accurate reproduction of sound” and if products cannot do this they are, in my mind no good for either. I would love to discuss and debate this with you further, nothing better than a meeting of minds , everyone learns but time is very limited in this particular forum. It would be great to meet you some day.

I wouldn't say big trouble :-) just try these settings and see how you go!
