50w Cloud amp - too little...?

#1 Post by AlBrum » Mon Sep 28, 2020 8:51 am


I have a four channel Cloud amp - very efficient and reliable make in the UK - used in many installs in bars for zoned music distribution, worth £550 got it for £75 (!) 4 x 50w

I run two conventional wedges on it (bridged to 2 x 100w). Works fine for the band: 1 monitor at front for sax player and singer, 1 at back for drummer (just needs vocals)

Thinking of running wedgehorn 6's for foldback- one for vocalist =, one for sax player (who like her sax LOUD - so overpowering the vocalist currently) and one for drummer for vocal cues. I might add a fourth at some point when stage is spread out for percussionist on right of stage..

Is 50w a wedge going to work with wedgehorns. We keep levels sensible on stage, but is that cutting it a bit fine do you think?

Here's what the WH6 plans have to say about that
The recommended woofer is the Eminence Alpha 6a. It will take about 50 watts at 120 Hz before reaching its excursion limit (xmax), which is twice as much as is generally required of a floor monitor.
Should work fine.
Build in process - 2 WH6, one Alpha 6a loaded, one PRV Audio 6MB250-NDY loaded

Two 2x6 shorty SLA Pro's
One T39, 16", 3012LF loaded
Tall AutoTuba, 20" wide, 2x 8" MCM 55-2421
TruckTuba, 8½" wide, 2x 8" MCM 55-2421

Going from 100 to 50 watts you lose 3 decibels. Psychologically to your brain you might say it's "80% as loud". I'm not sure of speaker efficiency difference though the wedgehorn 6 won't be as good if you have bass in your wedges.

You won't lose 3dB when you can't put more than 25w into them anyway before they're too loud.
