Can you picture your v5.0 and provide some sound testing. In terms of outside performance, the Aiwa Exos 9 was previously tested to disturb a whole village and heard 600m far. Based on that, we can guess the DiamondBoxx can be heard half a mile away. That's pretty impressive loudness.
Well I just had the V5.0 outside for a non-neighbour friendly blast session.
We're on the high side of the street and have a house directly across from us which is probably 50 metres away. The sound bounces off this house and causes a very strong delayed echo. Walking around the corner, you can still hear the bass and highs very clearly and it's still LOUD!
I was particularly happy with the way the highs and bass carry so well outdoors. However, I think for residential purposes, at max volume, it's simply too loud. I can imagine people calling the cops on me before too long.
