    Hi all!

    I may be moving into a semi detached house and am trying to get an idea for my HT setup. Basically all living rooms are on the attached wall that connects to the neighbours, I am worried about my setup being too loud and don't want to be the annoying loud neighbour. Once I move I do plan on speaking with the neighbours and getting a feel for how loud becomes a nuisance for them however worst case scenario and any reasonable volume for me is too loud for them I'm trying to think of new plans.

    I am curious if anyone has experience on this but basically I am wondering if I was to set the speakers up closer to the sofa so that quieter volumes are still loud from the sitting position would this negatively effect the sound?

    I don't have exact distances measured but will make some numbers up for the sake of explaining but in theory the plan would be to have the screen setup lets say 8 metres from the sofa, If i then placed the front L/R and sub say 3 metres from the sofa how would this translate? Would this allow everything to be turned down but then still sound nice and full from my sitting position? Or would the sound be too disconnected from what's on screen?

    I've done a quick picture to show the potential plan. Has anyone tried or run a setup similar? How does it fair compared to the usual positioning of either side of the screen (which is my plan originally and this is a last resort option)

    Appreciate any help.
    Cheers!

    If you are bothered about the sound, look at putting some sound proofing up on the adjoining wall in stead of placing the front speakers and woofer where you have do in "setup.jpg". What you have suggested is something that I would not recommend in any way and the speakers are really to close and there is nowhere for them to work off. Almost all 5.1 systems and even ones with a phantom front need to be placed in the right place which is usually around the front of the room with the rears to the rear of the room

    Take a look at this website to see how to setup a 4.1 system up with a virtual centre channel. This should enable you to understand why your choice of setup is not ideal for surround sound

    I did think about soundproofing but it seems the only way to do it effectively is a room within a room? I can't just place something on the wall as that wouldn't do a lot. The place is rented so any major changes aren't really an option. I had a read of the Dolby site you linked but I'm still not too sure why bringing the fronts out from the screen is a problem? (sorry if I'm being dumb!)

    My thinking was that if the fronts are still evenly spaced from the screen/listener and setup correctly with the distance from listener on the receiver and also with the pink noise and a DB meter then sound wise they should behave the same way as if they were placed a few metres back and either side of the screen? I just wasn't sure if the sound would feel disconnected from the screen.

    If this does actually present a problem then I am happy to try and find another solution, I'm just not too sure what the problem would actually be atm.

    Cheers.

    Just want to add that my diagram is pretty poorly done, the speakers wouldn't be as close to the seats and as wide apart as they look on there as i know you would be able to hear each speaker individually... but if they were slightly narrower so that the sound would cross over from each one in the seating position would that then work?

    Where we place the speakers in a room has a direct effect on how they sound as the room has more of an effect than some people think. Placing them to far from away wall can create even more boom whereas placing them to close to a wall can create a very thin sounding speaker. Plus how we hear the waveform from the drivers in relation to where we sit also has an effect on how we hear the entirety of the speaker too. As a rule, you'll be best to follow the guidelines as there is far more science going on here than my explanation, but everything will just work better for you including the volume levels too if you follow the guidelines :)

    I agree with Shane - I do understand that being in a rented property limits how much you can do regarding any permanent alterations, but you'd be surprised how much difference a wall of thick material can make to deadening sound.

    Is your new living room connected to their living room? When do you watch your films? Does your AVR have a "quiet room" setting i.e. it still plays full range but at a lower volume?

    Interesting query, though. At least you're only renting!:)

    Agree with Shane and Derek, your proposed front speaker placement is likely to cause more problems than it will solve and be too remote from the screen. The sub needs to be placed where it will give a good clean bass response and the sub is more likely to be the cause of annoyance to a neighbour. Some receivers are able to limit the subs influence by having a 'containment' option, some of the Denons and Marantz have this ability.

    Cheers Shane yeah that makes sense. I think my best bet is to get the speaker in there and do some tests as they might not even cause a problem yet! But I will play around with placements and distances from walls and see what works and what doesn't. My current setup works fine and has the speakers set next to the screen, I'm thinking the sub will be more the problem anyway so I will make sure I have it set properly and test out volumes and see how the bass travels.

    Derek - that is a good point, are there any materials in particular that people recommend? I have to ensure the room looks nice as well as being setup for my HT as per the GF's wishes, my plan is to go for a dark shade of (possibly) purple on the walls and ceiling to darken it (not as dark as I would like as I still expect light reflection) but that means it will still look nice when used as a normal room. I'm not sure how she'd feel with material stuck all over the place :laugh:

    The living room is connected to the neighbours yes. I mainly use it with the PS4 and that's on a night and weekend and my receiver doesn't as far as I have been able to tell it's an Onkyo tx-sr333!

    I just had the thought of doing a tighter setup like that and tried googling it but found nothing which is what prompted me to post here myself! Thought it would be an interesting experiment although not ideal!

    Agreed with the sub being the main problem. I don't think my receiver has any options other than turning it up and down in the calibration settings. Worst case scenario I will limit the use of the sub or have it set very quiet just to add a little bit more to the bottom end

    Correctly set up the sub will response to the master volume of the receiver.

    With the Sub, if you are worried about excessive boom. Place the woofer where you want it. Let it make some noise and walk around the room, if you find its booms on the wall your bothered about, move it to a place where it wasn't booming and then test again. With luck, that will have solved that issue for you :)

    Sorry for the misinformation there, the sub does turn up and down along side the rest of the speakers when using the master, other than that the sub has its own volume control on the back and can also be +/- in the speaker calibration menu when you adjust them individually whilst they play pink noise.

    Thanks for the suggestion there Shane I will try that :) I'm thinking I will place the sub closer the the front right speaker as that is away from the attached wall but I will definitely test walking around and hearing how it sounds from different areas.

    Luke (ee!) - there's a separate Forum on this site for people building their own Home Cinemas called "Home Cinema Building DIY". Why don't you post a query on there about suitable sound deadening material for one complete wall?

    And at the risk of sounding like I agree with everything everyone else says, I also agree with Gibbsy and Shane! I live in a flat and have neighbours only beneath me. They've told me that they only ever hear my Subwoofer during big explosions, but otherwise don't hear the rest of the soundtrack (which surprised me, I must admit).

    Have you got your Sub isolated from the floor using a plinth, riser or platform.? Or even just an offcut of granite? Again, this can make quite a difference regarding boom and can really tighten up the bass response.:)

    Hi, cheers for the suggestion about the DIY forum, I'll probably make a post in there if it comes to needing to get some sound insulation on the wall.

    I don't have an isolation platform for it atm but I did look at them as I saw a few people suggesting them on another forum. I may get one anyway though as you say they can tighten up response, do you have any in particular to suggest? Good to hear that you manage okay in a flat, how loud do you normally have things running? Bit of a tough question I know!

    No problem!

    Probably the most famous Subwoofer isolation platform is the Subdude:

    Auralex SubDude II subwoofer isolation platform for sale | Bax Music

    But it's very expensive for what it is. I've seen something like this which seems pretty much identical and does exactly the same job, but doesn't have the brand name attached:

    AcouFoam Speaker Cabinet Isolation Pad by Gear4music, Medium at Gear4music

    I know which one I'd try!

    For me, because I'm in a flat, I've gone a bit mad with trying to isolate my Sub. As well as having two thick offcuts of heavy granite placed underneath, I'm also using these too:

    SVS Soundpath Isolation Feet (4 Pack) - Spikes & Isolation Feet - AV Online - UK Home Cinema and Hifi Specialists

    And my 15" Sub has its own EQ to further reduce boom!

    Volume? My AV receiver volume runs from 0-100 (I think) and I usually play films at 55, sometimes 60 if it's a Sci-Fi/action/thriller with lots of explosions! My system is 5.1.4 and my LCR are two floorstanders and a large Centre speaker.

    I do notice that games consoles tend to vary from game to game - some are booming and others are quite quiet, there doesn't seem to be a universal standard like there is with films and TV, so volume can vary quite a lot between games.

    But then games tend to give you the option to increase or decrease music, effects and dialogue volume in a way you don't get with other media.

    Any more questions, just ask!:)
