    Are there any budget limitations or SPL requirements?

    Ok, so there are no budget limitations. Lucky man. [​IMG]
    The SPL question still needs to be answered, though, as I can design a tiny box with an 8" woofer that will "do" 25Hz. It won't be all that loud, though, to put it nicely, which is the case with that Boston, I suspect.
    Anyway, you're probably looking at one of the Velodyne models is size is the chief requirement. Is it the "footprint" that's a limitation, or the height, also?

    This one meets your criteria and for the price is hard to beat, IMO.

    Felix, I only laugh at myself, so I never run out of amusing material. [​IMG]
    Spl is sound pressure level. How loud to you want it to go?
    For example, if you have a DD home theater system, do you calibrate it to reference levels?

    Well, that's up to you. There's a certain capability the sub should have depending on how loud you listen. For full reference levels in DD, the sub needs to be able to get to 115-120 db, which is well beyond any "small" sub I can think of.

    Vin's suggestion is excellent, and not too big.

    Felix,
    From what little I know, your question will need a lot of qualifiers in order to get the best answer.
    For starters, room size (LxWxH), desired listening level, etc. Apparently, a lot of subs can say they go under 25Hz, but if they do that with no volume, what good is it?
    If $$ is no object, check out this thread and take your pick.
    By small, do you mean footprint? If so, the SVS qualifies. But it is a large cylinder sub. So it definitely has a "presence." [​IMG]

    Any restrictions at all?
    Money?
    Wife?
    Mother in law?
    Size?
    SV subs are known for deep bass on the cheap, without looking cheap.
    Let us know the budget, when you will buy, room size and all that groovy stuff....

    ok. next year gonna buy a house.

    living room 5 meter times 6 meter.

    i dont like the looks of the svs. it is like hotdog on a stick. too distracting. wife wont object even though i buy the 18 inch sub from velodyne, but i hate anything that looks big.

    ok, i want frequency under 25 hz to be audible as my dog barking on my face. but i also want it as small as possible, and if that costs me 2000 bucks i will go for it.

    floor : carpet.

    Small? You want small?
    http://www.sunfire.com/products/submark2.shtml
    How's that for small? Sure, it's $1,500 (can be found for $1300 or less), but at 11" cubed it's the smallest sub on the block. Sounds good too, down to 20Hz.
    Edit:
    hahaha, Neil beat me to it... still, this is the answer if size is your main concern.

    felix,

    Can you hear 25Hz? I can't. My hearing drops out

    at 37Hz.

    It sound like you are asking for 25Hz at 75db, 12ft

    from the front wall. Is that right? If so, thats 4 PB12's

    lined up on the front wall. Are you sure the structure

    will stand up? I think that anything meeting your 25Hz

    spec would be quite uncomfortable at 70Hz. Therefore, a

    low-freq graphic equalizer would necessary.

    not sure whether i could hear 25 hz though. but human ears were said to be able to hear 20 to 20000 hz. so what is the purpose of creating 25 hz sub if you guys cant hear it? at least you can feel it, right?

    No, we can't feel it either. However, we think we can, and

    our sound pressure level meters tell us its there.

    Just get something, and put it in the corner.
