Subwoofer size to rock any bar.

Minimum I'd go for in a PA type sub is 18". As I said, my/most PA speakers already have 15's in them.

I'll be honest. We run 2x QSC KW181 subs, and we're already looking to see what we can add that would add a little bit more. We've done sound with bigger production companies before with some larger passive subs setup as well, and it's amazing with the extra punch added on.

We are stuck deciding if we want to get another pair of 181's, or if we want to start venturing into the realm of passive. (We run a monthly in a one-room venue at the moment that is decent size, expanding to other venues in the future, completely mobile setup).

Personally I wouldn't go anything smaller than dual 18's. But I also think sound quality is the most important aspect of a night.

what are you talking about man?
First of all, the difference between 1 sub and 2 subs is +3 db.
This one sub will pound an average size bar (50 feet x 60 feet, low ceiling) He did say bar, not club.>

Wrong. Doubling cone area and power, while coupled, theoretically adds ~6db to your total output. This is quite noticeable and gives you quite a bit more legroom over a single. A dual 18, corner loaded, will do quite well in most small to medium venues. However, most singles (yes, even the KW181 or even an SRX 718) will struggle, even corner loaded, in a loud environment.

Those Yamahas are decent for the price... but a single will certainly not "pound" anything other than a coffee shop.

Of course this is all controlled by what his client is willing to pay. I wouldn't bring dual 18's for a $200 gig either. In that case, don't even bother with subs. Get a good pair of 15" tops and call it a day.

Personally I wouldn't go anything smaller than dual 18's. But I also think sound quality is the most important aspect of a night.

This is also an important point - remember you don't have to (nor should you) use the full output of your subs all of the time. Granted, with a single sub, you're going to have to. But going with multiples lets you run them at 80%-90% to decrease distortion and increase low-end extension. They'll sound better, last longer, and your amps will thank you.

That Yamaha DXS 15 is all you need for a bar.

He said a bar. Which I'm assuming is not much bigger than an average restaurant.

I've played backyard pool parties with one DXS 15 (not corner loaded) and it's been great.
