The Fugoo XL appears in some of Oluv's reviews and comparisons, it is a really small speaker, roughly comparable with the Beoplay A2 or a bit above. That means it's like the small Bose Sounddocks at best, or like B&O Beolit 15, but less refined.
I have used such speakers for very small congregations in chapels, but only if the audience is quiet. As soon as there is chatter, it won't suffice. The Klipsch KMC-3 is a lot stronger, next level would be Beoplay A8 or A6 or Bose Companion 50, probably Teufel Boomster XL or Aiwa Exos-9 in the same class, and Bose Sounddock 10 still louder.

You can compare the Fugoo XL to some others here in Oluv's tool. Select Fugoo XL and another speaker and "maximum volume".

I recently bought/ tried several smaller speakers as there were some incredible prices. The latest I got is the B&O Beolit 15. I can really recommend it as a monitor and e.g.for small churches with quiet audiences. The bass is absolutely incredibly deep, and the general sound is very refined although not neutral.
With these small speakers You have to pay attention regarding distortion with piano sound. While normal/orchestral music is often rendered without any problems, pure piano sound sometimes causes a very bad distortion in the upper third of the volume range.
For this reason I recently returned the Vifa Helsinki, an absolute high end speaker. It couldn't cope with the massive mid frequencies of a piano sample. Same applies to the Sony SRS-X88. The Beolit 15 has absolutely no problem with it.

Heard the Fugoo in the store wasn't impressed,.......butI have a few of the JBL Charge 2 units and they sounds amazing for a Bluetooth speaker.

The Charge 2(+) was one of the better pocket speakers before the Charge 3 and the Sony SRS-XB3 were recently released. But this size of speaker is just enough to hear yourself play alone in the living room. The Fugoo XL is definitely much more powerful than the Charge 2, no doubt about that.

Here's one of Oluv's comparisons between Fugoo XL and Charge 3 (which is MUCH more powerful than Charge 2). The Charge 3 has no chance against it - but BOTH are no serious speakers for live amplification. It starts to get serious with the old Bose Sounddock portable/Soundlink Air, Beolit 12/15, Klipsch KMC-3 for background piano music and similar.

And I forgot to mention, what I'm most impressed of, is my pair of Genelec 8010. A really HUGE sound for their tiny size and only 7 lbs per pair. And of course premium studio monitor sound quality. They are stated to go down only to 73 Hz, but the bass sounds much deeper. No distortion of piano sound even at high volumes. It's bizarre: Some years ago I tried the bigger Genelec 8020B - they did distort with piano sound. These small ones don't - and they are much better than the former 6010. Just one small inconvenience: they require XLR cables.

P.S. I'm going to make a video demo of them some time.

I only use the JBL Charge2 for with my cell phone on the patio & it sounds great ......but in no way would I play music thru it with my KB, etc,......

I can't see anything in your last post, only the quote. Ah, probably a video. My smartphone can't display it...
EDIT: It was my smartphone, sorry.
Yes, great as a small studio monitor, but after my tests I can really recommend them as tiny live speakers as well. And unlike these one-piece speakers they provide a great stereo stage, too.

This interesting thread is becoming an expensive influence on me: I thought I was going to buy the Aiwa but now I am looking at the B&O Beolit 15 and the Genelec 8010, and I am saying to myself that these two are for different purposes!

Just heard some great news. And the international version of the aiwa exos 9 will be available in August this year from Amazon . Got this information direct from the company.
