Sorry i meant to say they are a 4 piece band with drums, bass and electric and acoustic guitars.
And they mostly play in pubs but as they get more popular will also likely play in nightclubs and some outdoor street gigs
Unfortunately the QU-16, though ideal, would be way outside their budjet.

With PA speakers yielding an average sensitivity of around 95 – 110 dB/W/m, a 100W speaker with a sensitivity of 100 dB/W/m would produce 120 dB (at 1m) at it’s max 100W input power. A 400W speaker with the same sensitivity of 100 dB/W/m would produce 126 dB (at 1m) at it’s max 400W input power. Twice as loud.

For a 100W speaker that produces 125 dB, it would have a sensitivity of 105 dB/W/m and an efficiency of 19.95%.
For a 400W speaker that produces 125 dB, it would have a sensitivity of just 99 dB/W/m and an efficiency of just 5%, a very in-efficient speaker….you could warm your hands off the back of it while listening with all that wasted power 🙂

I’d prefer the pound of feathers meself 🙂 Speaking of feathers, if you dropped a feather and a lead pellet in a cacuum tube, which would hit the bottom first ??

Chill out man, there’s loads of topics on this forum that are not strictly QU related. Have a nap and relax dude !!
