** Finally got to hear a Bumpboxx !!! **
The other thing I collect is vintage AC fans. I was at a fan sellers house and noticed a Bumpboxx in his lounge room. Turns out his visiting nephew who was on school holidays brought his box with him.
I had to hit him up for a demo.

He’d not yet heard it and was interested as he is also a HiFi enthusiast. Via BT, I hooked up my IPhone and played a few tracks. After a short, 10 minute indoor test, here are my impressions:
The good:
Loud!! **** this thing just screams!!
Relatively light weight when you consider the size.
Looks cool with the 10 inch drivers and flashing lights.
Heaps of input options.
The bad:
Sound quality is fair - strong, boomy bass but the mids were lacking. Overall clarity was limited with some frequencies either missing or subdued. The bumpboxx definitely ‘sounds’ mono. We are all aware that perceived stereo separation almost disappears when you sit a sufficient distance from a box. But even with that in mind, it sounded more ‘mono’ than a stereo Boombox would sound from that distance.
This is only my opinion. I know there are many people with different tastes in sound that absolutely love the Bumboxx sound.
This is definitely an outdoor box. Outdoors, I’m sure the boomy mid bass and peaky highs would sound ok. The compromises they made to achieve maximum loudness on 12 volts (Mono amp) and the use of horn tweeters make sense for outdoor applications.
Unfortunately, this does mean that for indoor, high fidelity applications, there are better choices.

P.S I tried the FM tuner - I couldn’t get it to lock onto a station so nothing to report.
