    Morning lads

    I'm looking at subs again after failing to come to a decision a while ago. My room size is roughly 14.9 x 14.5 x 8.6 ft. Which if i'm correct is approx 1850 cubic feet? What size subs should i be looking at for this area.

    It'll be used for both music and movies so a sealed sub is a must. The sb2000 and the xls400 are what i keep looking at. A Sunfire with EQ is also grabbing my attention.

    Any help is appreciated.

    For that size room I'd say SBU13. I have used a sub similar to SB2000/XLS400 in a room smaller than yours and it wasn't impressive for movies.

    For music only those two will be plenty.

    A lot will depend on budget, space available (footprint, height, overall max dimensions), how loud you play things (movie 'Reference' level or just -20 on the receiver because of kids / neighbours / etc) and if there is WAF to consider ;)

    I would suggest either dual SB2000 or Dual BK 400. SB 2000 are much smaller than the BK size wise and are better but costs more (especially you could have second hand BK 400 for around £300 these days) SB 13 ultra would be better but much huge in size. Also dual subs might even out the bass reponse in the room. My roomies 1300 cu feet and one SB 2000 is plenty for movies and music, I did run a dual setup briefly before I sold my previous sub bk400 and the dual setup certainly produces good punch. I'd definitely run a dual setup if I had the space.
    If you are not going to go down the sealed route, then either an Svs PB 2000 or XTZ 1x12 might do a better job than any of the single sealed subs you mentioned in your larger room

    Cheers for the input,

    I've considered the sb13 ultra and love the look of it, I just wasn't sure if it was necessary in my room? I suppose I wouldn't need to change it for a many years. I would just have to wait a couple more months to save the extra £££.

    Dual sb2000 would look very nice and symmetrical in the living room which the Mrs would like.

    With regards to volume levels, we don't watch films even close to reference level due to the kids being in bed. However, we do have very noisy neighbours who like to play music very loud at random times throughout the day/night. So I'm not one bit bothered about annoying them with ridiculous bass during the day from music.

    Two sb2000 in black gloss is roughly the same as 1 SB13 ultra. It's just a question of would dual sb2000 be better than sb13 ultra?

    guy on avs had dual SB2000, and changed to single SBU13.

    he said the single SBU13 outclassed the dual SB2000. He's now bought another SBU13 for dual SBU13 action lol.

    Also I had single SB12+ and pretty unimpressive for movies, I doubt another would help much.

    They probably come close with measured performance but the tonal quality of the 13 Ultra will sound superior. When I had the PC-2000 and upgraded to the SB13 Ultra the difference in refinement and bass definition was immediately apparent and in a way it made the PC sound a little monotone.

    Paul, I would've thought the PC/PB2000's may have had a slight advantage over SB 13U for movies as the spec says they go a couple of Hz's lower. But hey who am I to argue as you have had both in your room to compare. It would be an interesting comparison between Dual SB2000 vs SB13U, as both are sealed and roughly costs the same.SB 2000 may have a different character in its tonality compared to PC2000 ( again not heard the PB or PC myself)

    In small rooms (-2000cuf) a sealed sub will usually go lower than a ported but it won't have the output a ported sub has, but with some room gain the sealed can make up for the lack in SPL.
    The SB12-NSD (previous model) has some output at 12hz and the SB13 Ultra at 10hz

    The JL Audio E12 (or whatever it's called, I can't remember right now :facepalm: is also very compact with a lot of output, so that might be another option, but it is somewhat more than the BK or SVS, I believe.

    Do you have a sub now? How is your seating laid out - all in a row or spread around the room?

    If your seating is all in a row that might make it more viable to get away with just one sub, but if you have seating in different locations you might risk them all having a different response - with one seat quite quiet and another seat a bit boomy, for example - so two subs might help smooth the response across the room.

    If you already have a sub then you should put it in your seat and then do 'the sub crawl' to identify the best position for the sub in the room. I fear it won't accord with your desired design aesthetics :laugh: but that's always the way... lol


    Oh, and while I'm typing, can I say those three letters that are muttered in hushed towns in this section of the forum... DIY :devil: :p

    Might be worth looking at the XTZ or PSA offerings as the SVS isn't the last word in subs these days. I also would add that I have a slightly bigger room (approx 2300 cuft) and run a pair of sealed subs that fill the room more than adequately at over 110dB down to 10Hz, so ported isn't the only option in a bigger room (though you do need more power to achieve this). However I'm talking non commercial 15" subs, so not so relevant to the OP.

    I don't currently have a sub so can't do the "sub crawl" just yet. The living room is almost a square. My AV kit sits along one side one wall and we've a new sofa being delivered on Thursday which will basically cover the entire opposite wall.

    Ideally with two sb2000, they would sit nicely besides the KEFs. If was to get the bigger sb13 ultra I'd prefer it to sit behind the door firing across the room or in the corner.

    That JL is to expensive for what id be willing to pay for a sub. How do ppl rate the Sunfire subs with eq? I wouldn't attempt a DIY jobby.

    Thanks for the input lads.

    Hi Rick,

    the Sunfire´s have a pretty good reputation and seem to perform pretty well for the size. There was a review on here for the latest 12" Sunfire sub and a matching thread as well.

    Having the build in EQ is a nice to have, but imho the build in EQ´s, no matter if it is Velodyne, JL or Sunfire will only be a compromise (Paradigms PBK might be the exception to the rule).
    You will imho get better results with an Antimode DC or even a MiniDSP. But this will come with additional costs associated.

    You should download Room EQ Wizard (REW) and play with its room simulator - you can work out the best positions for placing the sub(s), which should reduce the need for EQ if you can place them in the locations you find to be the best on the simulator!

    Hi REM,

    I'd look at a pre owned Sunfire but the model in the review is too expensive. I noticed Movie Rooms are selling some the HRS 12 and the Atmos XT with a decent discount at the minute (new models due out maybe? ) The Paradigm Seismic 110 is also very good by all accounts.

    Good shout. I'll have a look when I get chance to start up the MAC. I'm guessing it's not IPad compatible ?

    Just downloaded REW, how on earth do I set it up? Lol.

    Can I use the Audyssey setup mic to take the measurements?

    Cheers DaneP, it looks a tad more complicated than I initially thought.

    Indeed. I've only used the room simulator function to help me place my subwoofer but I found that to be quite intuitive and has yielded good results so I'd suggest starting there. General consensus seems to be that the simulator is accurate enough to tell you whether you're going to face any major peaks or nulls in your room.

    Just reading through the link DaneP posted, seems like a lot of extra kit is needed.
