Help! I need a tiny subwoofer! Any Suggestions??

Hey Everyone,

I am building a AV display case for an upcoming trade show. The case will have a LCD monitor mounted in it and a small sound system. The last case I did (see link below) I used FBT Jolly 5A speakers which are great, Im just looking for a little more bass. The problem is that the sub needs to be small, I was thinking along the lines of 2 reference monitors and sub. I would like to stay in the install/PA realm because of durability and volume, but I am open to suggestions. Thanks for your help!!

the amount of bass you get from any speaker is proportional to it's size. small subwoofer = small bass. it's physics, nothing can be done to change this relationship.

It looks like yr cases are pretty decent in size. I'm sure an 8-10" sub would work pretty well. While not best for studios, i'm sure one of the krk subs would work fine for your application.

not necessarily... you just have to move air. you can trade excursion for diameter, and also there are other ways to move air besides a cone attached to an electromagnet

this clever little guy will go down to 1 Hz. 110 dB. And it's only $12,900!

Yes, but you lose efficiency. If the membrane is small, much of the air moved will "spill" to the sides, rather than travel into your ears.

Compare two speakers with the same power, but one with the bigger membrane than the other...

I used to have a pair of old speakers. Only 60 watts, but big 15" membrane. Damn they sounded good. Accurate bass, beautiful definition. Only way to achieve that sound with a smaller membrane is much, much more watts... and it still won't be the same.

Tannoy TS-8 is the only thing I've heard that still a pretty smalle footprint and sounds good. I really don't like going below 10" woofers though.

How small is "small" for the sub? How much bass is "a little more bass"?

Any speaker will produce movement down to 1Hz. The question is whether you'll hear it. The smaller the cabinet in relation to the driver the stiffer the air behind the speaker, which restricts the speaker's movement thus making it's low frequency output less audible at practical distances.

You can attempt to overcome this with more power and a larger driver but you lose sensitivity due to driver mass increasing. You can attempt to get a little more low frequency extension with a port but then you add the potential problems that ports bring, which is really only an issue if you're using the thing for critical listening. If it's just for display, casual listening then any 8-inch, ported sub ought to work fine.

Frequency response 1Hz – 30Hz +/- 4dB
suggested crossover 30Hz @ 18dB/octave
Sensitivity 90dB 1 watt 1 meter @10Hz
Maximum acoustic output >110dB between 1 and 30Hz.
Goodness gracious- It crosses at 30! It's a sub-subwoofer.
5hz @ 110dB I think has military applications!
And all for the low, low price of $12,900!
There are some crazy f**king people in this world.

At this point I am leaning towards the Behringer Truth B3031A speakers with the B2092A sub. I think this will be more than adequate. Any thoughts? I know everyone hates on Behringer here, but the Truth speakers are actually great; although I dont have any experience with the sub.
