Hi

I am projecting onto a large white wall. The wall is freshly painted white and almost 213" diagonally. The entire room is roughly 20 feet by 20 feet and freshly painted white.
I'm using the projector at night only for watching movies and the room is almost fully darkened with curtains.

I am deciding between three projectors: the BenQ W1070, W1070+, W1080ST and W1080ST+.

I have two questions:

1. Would the W1080 with its much shorter throw have any advantage in terms of maintaining the contrast in the image? I supposed if the projector is placed closer to the wall, the amount of light bouncing around is also much less?

2. The difference between the regular and + models is that they have 200 more lumens. I calculated that with the W1070 and W1080ST, I'm getting 13 foot lambert. With the +versions, I'm getting 15 foot lambert. Is the 2 foot lambert significant enough for the viewing experience or will the 13 foot lambert be sufficient enough?

Thank you for taking the time to answer my questions

Hi all,
I don't know if this is the right place to put this, but its where I think I will find the most balanced opinions from those that have been the whole hog, and maybe, back again.

I have some some people online on various forums, youtube, and other places, that have gone from dedicated home theater rooms with atmos 4k blah blah blah, and after some serious personal thought and apparant soul searching, decide to cut right back to just a TV and stereo speakers! Now personally, I don't understand why anyone would do this. Perhaps that's just because I am in the middle of the upgraditus whirlwind, maybe I'm just ignorant, I'm not sure. Maybe one day I will understand? :confused:

Some call it simplifying, others just lose interest in the hobby and want to reclaim their space back, others have been 'forced' into it to maintain certain relationships in their life. I get those reasons, but hey, I just want to understand it a bit more when someone 'simplifies' by choice. Why?

If that's you, or someone you have known or observed, I want to hear about it. I want to hear your opinions. Help me understand...WHY!? :(

FROM THIS


TO THIS - WHAT???


EDIT: The pics above area bit of an extreme exaggeration, but you get the point of my question.

Hi, I am planning to build a dedicated HT room in the basement which has no windows so pitch dark if entrance door is closed. I am thinking about 120" and based projector throw requirements, it seems my only choice is to go with ultra short-throw laser projectors.

Please review included photos and I have following questions:
1) Given the 12ft viewing distance, having 120" screen an optimal size?
2) If speaker wiring becomes a challenge through walls, is Bluetooth based L/R/C speakers a good option?
3) Should I get two or one subwoofers?
4) Is repainting the walls to darker color worth it?
5) Is it a good idea to 2nd row seating on the front of sofa and risers for the back given the size of the room?
6) Any lighting suggestions to re-purpose current BR30 recessed lights?
7) Any suggestions on projector? Usage is 50-50% gaming/movies and my budget is up to $5K and I debating between new LGU85LA, VAVA 4K, and Optoma P1
8) I already have BIC America PL-76, PL-200 sub speakers that are 6 years old. Is it worth upgrading them?

Anything else you suggest to make this home theater room great...

I'm considering buying a subwoofer. In this previous post, I didn't ask what my power requirements are in order to fill my room, so I'm asking now. What I think I really need to know is, how much subwoofer power is required to obtain output at a certain perceived loudness level in a room of a certain size?

What I think I need more than recommendations for individual subwoofer models, is what specifications should I look for, and how do I find subwoofers with those specifications.

I'm also going to go through the questions mentioned by one of the stickied threads as questions that people asking for subwoofer recommendations should answer.

Primary uses: I think that the choice of a 'music' sub over a 'home theater' sub (or vice-versa) is a false choice. Ideally, I want a high-quality sub that is great for everything: TV shows, movies, games, and music of all genres.

The volume at which I listen to content: first, a little background information. I set the volume level display option on my AVR to "relative". My source for TV shows, movies, and games is my Xbox One S, and it only allows bitstream passthrough for its Blu-ray player app, so my listening volume changes across apps due to my Xbox's inability to output a constant volume across sources, due to the lack of bitstream passthrough for most apps. However, so that I can give you a numerical value for volume, and since the Blu-ray player app has bitstream passthrough support, I popped my Gravity 3D Blu-ray (which has a dialog norm value of +4) into my Xbox, went to the dialog-heavy part at the beginning (prior to the action), and increased the volume until the dialog got to a comfortable level. It got to -18.0 dB. I watched the whole movie, and the volume seemed about right. Then, I ejected Gravity and inserted Top Gun 3D, watched it, and throughout the movie, I gradually increased the volume to - 17dB. It was a bit too loud during the battle scene, but I guess it was a good volume for the quieter scenes. Obviously, different content might sound best at different volume levels. Why am I mentioning all of this? Because I'm wondering about a subwoofer or subwoofers that will match the volume of my main speakers, all the way down to 20 Hz.

To add to that, I wish I could get accurate reproduction and equal loudness of ultra-low frequencies (< 20 Hz). That might be too unrealistic, so it is not mandatory. To be honest, I haven't experienced frequencies below 20 Hz at appreciable volumes, so I don't know what I'm missing and whether it's worth it.

Room size and layout: my home theater system is in a room that serves as a home theater room as well as a bedroom. I've attached a crude drawing of my room's layout. You'll see that there's only one chair, and that's because usually I'm the only one watching. Occasionally, however, I'll move this chair to the left in order to make room for another chair or two, which I can bring in from another room, so that I can watch things with my mom and/or with other family members when they come over.

My budget: I don't have a set-in-stone budget. I want to know what my options are before I decide how much I'm comfortable spending.

Subwoofer enclosure size limits: I don't have a set-in-stone size limit. I want to know what my subwoofer options are.

How soon I want to have a subwoofer or subwoofers: I am interested in buying a subwoofer or subwoofers, but I'm not in a hurry.

I noticed that my Klipsch R-10SW subwoofer is making a noise known as chuffing.

Does anyone know if this is common in this model?

Any indication of subwoofer in this price range?

Thanks

Let me know if this is the right section to post. I am new to the forums.

So I had an electrician come over and measure few things in the house because my LG OLED TV has suddenly broken (green line showing in middle of screen when turning on and then it turns itself off). The only thing that he found to be out of order was a measurement of 40 volt on the metal connector of the HDMI cable going from my Nintendo Switch to the TV. Is this a normal reading? And if not is this voltage something that could have fried something in the TV?

So... recently a friend of mine was utterly amazed when she heard my home system and decided to upgrade her own home audio. I was tasked with finding her the best possible sound under a budget of $2000. Her current source of sound is an LG Oled panel, 75" i think. She does not want projection since it is a shared living space/media room. It is a massive space, around 20x20 which opens to the rest of the house through corridors.

So far i got the JBL Stage A190 pair for $648 with a JBL Coupon
and an Onkyo TX-NR777 for $349 from A4L
Which leaves me about $1000 to work with for a sub or subs. Which sub would be ideal in this case?
Also any of those two above mentioned items can be returned for something else since i ordered it this weekend.

Hello,

I live in Norway (Region B). Blu Ray disks in US (Region A) won't play on my PS3 as I understand.

If I buy a blue ray player that claims to be "World-Wide Use" or "Region Free", will it be able to play disks from both region A and B?

Like this one from Amazon for example:

https://www.amazon.com/SONY-X800-Reg...s%2C313&sr=8-4

or this one:

https://www.amazon.com/Region-Blu-ra...s%2C313&sr=8-3

Thank you.

14x14x9 room & MLP 10' from cc, old ears, damaged hearing (tinnitis), 5.2.2 system, Yamaha RX-A660 (Aventage, 80 wpc), 75% TV/movies, 25% soft
rock, clear dialog is top priority. Don't listen loud (-30 on AVR). Currently using Elac Debut B5.2 and C5.2 for L/R & cc, consider them good on music
and ok on dialog but would like an upgrade. Since dialog is primary focus, looking at center channel and matching L/R. Budget around $2k.
Consider 3-way Ascend Horizon w/Raal one of best cc speakers available but height is too high for my application (8" max).
Evaluating (bs, cc): 1) Ascend Luna + Duo, 2) SVS Ultra, 3) Elac Uni-Fi, and 4) Klipsch RP (500 series). Each option brings a different
technology solution to my problem. Willing to upgrade avr (i.e. Elac Uni-Fi) but would rather do this later as the next step of improvement after speakers.
Appreciate any input or experience about these selections.

I have a Mitsubishi ws-55315 from 2004. I used to be able to sync and mirror the display from my chromebook laptop to the tv via hdmi to dvi-d adapter...in 1080i resolution with no issues. Now the only clear resolution I can get is 480i...which still doesn't look right. I've tried a couple different sources such as my blue ray player..a hdmi to component converter and my computer...and the tv wont switch to 1080i. The picture is just all distorted and wavy and flickering except for 480i. Both component inputs and dvi-d input are doing this. With the blue ray player I'll set the output resolution using yellow video output to either 480p or 1080i...and when I connect either digital signal from it it to dvi or component input on the tv...I just get the crazy distorted blur. Is there a chip of fuse in the tv that could have gone bad possibly? Any advice would be greatly appreciated...thanks

Have a new extension I'm building off my family room and am going to re-purpose my current Energy RC-70 reference connoisseur tower speakers and LCR from another room, and add surround speakers for a 5.1.4 ATMOS setup.

Unfortunately the Energy speakers I have are quite old now, prior to when they sold. The subwoofer I have is from SVS.

I know for ATMOS you want timber matched speakers, but in this case I gotta find the best I can to work with the RC-70's. Will upgrade my main to one of the newer Yamaha's (maybe RX-A1080 or RX-V2085), so maybe with the eq settings I can get them close.

Been a very long time since being in the know of speaker, so any help is appreciated! Looking at speakercraft LCR5's as seems they have a good selection for using in a ATMOS setup, but not sure how they compare to paradigm or martins, etc and if will even come close to working with the Energy RC-70's.

Quick question for the group: I'm planning to remove a door and build out the opening to support a flat panel TV in my office, which is one floor above my home theater system. Ideally, I'd like to run an HDMI cable to the receiver to connect to all the video sources there (about a 30' run, which I've done before to my projector). I primarily want to watch cable news, so I'd also wire up an IR repeater, like Dinky Link. The catch (of course) is that running these cables will require a lot of drywall cutouts and drilling through two firestops. From what I've caught up on in AVS threads, is that non-line-of-sight wireless options are not very reliable yet. Is that true? Any other thoughts? Thanks in advance!

I imagine this has to have been asked and answered, but I'm having no luck with a search:

Basement in the home I'm in has a recently installed Owens Corning system. Question I'm looking for is how to mount speakers on the wall for these systems. That I can't find a YouTube video on it is . . . troubling.

Anyone here have experience in these quarters?
