I'll reiterate that I would look to a commercial ("pro") unit such as this Mackie and just keep it on a mover's dolly.

Roll it out and plug it in as needed.

Umm, maybe I'm missing something here, but aren't all of the anechoic responses as stated on the Axiom product specs as measured from the outdoor tower at the Axiom plant? I know you'll give up volume and extension outdoors without the room gain, but you should still be getting some reasonable output, no? What am I missing? Why all the outdoor sub measurements then?

Boston Acoustics makes an interesting outdoor SW.

Their Voyager sub is discontinued, though.

if the OP decides to move the sub inside/outside, then i would suggest a cylinder sub, as it's about half the weight of the equivalent boxed sub.

have a look at this one, and read reviews too about it:

here's one review:

Yes, proper subwoofer measurements are either taken 2Pi (groundplane) or 4Pi (tower). This is done to eliminate the room and to properly compare subwoofer performance. However, the majority of subs out there won't do squat without room gain and rely heavily on it. For example 20 Hz at 100db is no more than a fart in the wind.

I think the mic is pretty close to the sub in those tests, too.

Ohio isn't that far from the Axiom plant. Maybe you could just feed your LFE channel over the internet up to Dwight and have them pump it out over the SWUT (SubWoofer Under Test) on the tower wink

You won't get full room gain but at worst you would get "ground gain" (sub is only radiating into a hemisphere rather than a sphere) and if you had a solid outside wall you could get at least half the output you would get in a room (eg -3db) which should make a pretty significant difference.

From a practical standpoint this should be do-able, and seems like it would be a pretty cool product. Downside is that ideally you would make it in some kind of inherently waterproof material (like the Algonquins) and that would have to be pretty thick/expensive for what is probably a pretty low volume product.

I guess this is another (wordy) vote for the moving dolly wink

Thanks BlueJay1 - that helps put in perspective. grin

Ken - good point about the mic placement, I completely overlooked that point.

Cheers,
