I have likely crossed this topic in some way before. Any of you out there who gig with an acoustic amp...for more room coverage, ever run from its DI line out to  a powered PA speaker or monitor? How did it go? 
 

I've never done it that way. What has worked well is plugging the acoustic straight into the board, and having a good level of the guitar coming thru a floor monitor.

i use my mini loudbox (https://www.amazon.com/Fishman-Loudbox-Acoustic-Instrument-Amplifier/dp/B003S3S0DU ) as a DI to my mix board, but have not connected to a powered mixer or directly to a powered speaker. presumably it should work effectively the same once the gain settings are all correct. as far as sound - i have coupled it with my older Roland cube - as well as by itself - it sounds good as a standalone amp, as a DI (the reverb and chorus come through to the mixer as well as the EQ), and coupled with the cube give me about 100W...

I've used an acoustic amp and DI'd it into the main mixer in the past. The amp being there to provide some localised "just me" volume and better eq facilities for a piezo pickup than many mixers have. Worked fine.

Doing the same into a powered PA bin should work just as well so long as it can handle the level of signal the amp"s DI puts out, which is typically mic level if the DI out is on an XLR socket. The only problems I can forsee is if the PA speaker hasn't at least basic eq of its own and the eq for the amp sounds bad in the PA bin, and the potential for earth loops and hum.

Putting a cheap small mixer between the amp and PA bin might solve both those problems if they arise.

Thanks . Interesting to read all the variations. I got some good ideas here to vary what I am doing a bit and just stick with something. 

One glitch I found if using the Loudbox for guitar and mic/vocal the DI (it is Xlr) line out is a a mix of both channels. So my next trial is to use my Loudbox for guitar only, since it sounds so good...and route my vocal directly to  a channel of my Alto Trouper PA. Forgot to mention that before any amp is my Play Acoustic , which ideally has seperate outs for guitar and mic. I place my Loudbox just to my right and slightly behind me for easy reach to controls and it actseems like a guitar monitor too, and the PA in front left on a pole.

yeah, i only use my loudbox for guitar and bass DI. vox go into the mixer directly or via my tube compressor then mixer.

OK we think alike...

In the days when I was playing out solo with acoustic guitar and vocals I ended up putting the guitar direct into the mixing desk. Via a DI if the pick ups weren't piezo and direct into the mixer line input for piezo pickups.

I found acoustic guitar into a guitar amp changed the acoustic character too much; too electronic if that makes sense.

Imho and others' experiences it's best to go to a DI before going to a PA (unless the board before has a preamp (pseudo DI).

Something to get the acoustic level up so it can be mixed at a middle level.

If the acoustic signal has to be maxed out to get into the mix there is typically more noise introduced.
