smallish dedicated subwoofer?

[J.Wolf]

I know this is a bit of an oddball question, but for a rig I'm assembling, I need a small cabinet solely for lows. I have two 112's run in stereo which sound fantastic for all but the deep sub lows. For the material and the instrumentation of this project, I need a cab that can put out those low frequencies typically associated with dedicated subwoofers, but in a manageable package (don't really want to haul an 18" speaker cab around).

What it needs to be: portable, powered (ideally), and reasonably affordable. I don't need a ton of volume or stage projection, just some nice extra bottom end on stage. Looking for something that really sounds good though, and not sure what is the best way to go, as this is kinda unfamiliar to me. Any help would be appreciated

Need a few more answers please.

First, how low do you have to go?
Next, are you willing to biamp?
How much size/weight is acceptable?
Why do you need this onstage? No PA support?

This is a huge difference between 31 Hz and 41 Hz.
You can get way down low, but not very loud in a reasonable box.

If you need 30 Hz, you can get this from a BP102 in a good size box, but still not very loud.
...certainly not a loud 'stage volume'.

Essentially, I'm playing in a group with two other guys, acoustic and electric dobro and a world percussionist. Both of those guys have their sound very dialed in, and very full range/high fidelity. Where I am normally more than happy with the full range-ness of my tri-112's, something about the context of the band seems to want a deeper low end on my part. I don't know exactly how deep I need to get, frequency wise, and its more than likely for monitoring on stage only. I'm sure most venues would want the full range DI signal from my pre to go their system, so theoretically the box doesn't have to put out a ton of volume, but certainly it needs to kick for a small stage setup.



First, how low do you have to go? it just has to cover the B string

Next, are you willing to biamp? In my mind, I'd be looking at this chain: Preamp w/ effects in loop > 1 line to powered sub with built in crossover, 1 line to stereo QSC amp running my 1x12's.

How much size/weight is acceptable? up to 50lbs, nothing bigger than a small 1x15 sized enclosure

Why do you need this onstage? I don't want to get all those lows from the tri112's (they can do it if EQ'd properly, but I would prefer to biamp my sound and separate the lows from the full range stereo effected signal).

thanks

See sig

Hoffman's Iron Law: To extend response 1 octave lower with equal sensitivity requires making the cabinet volume eight times larger. One can get around this to some extent by accepting lower sensitivity, but that means using a lot more power, and having a driver that can handle that power. In short, a small cabinet for lows isn't practical. At the very least it would have to be as large as your current two cabs combined.

those look cool, wonder if I could get away with eq'ing and powering one of those with my extra LMII, and get subwoofer-ish results

you need a fearful 12 sub. yep.
see greenboys sig line.

I hear you. the only thing that makes me think its reasonably do-able is the fact that I don't need it to push a ton of volume.

could a LMII > 12/6 do the job?
