Title: Danley TH 221, Powering?
Post by: Daniel Mock on April 08, 2011, 03:53:23 pm
I believe the TH 221 (http://www.danleysoundlabs.com/tapped_horn.asp?MODEL=TH%20221) has two drivers
each 3000W program @ 4 ohms.

I was thinking of bridging two QSC PL 4.0s (http://www.qscaudio.com/products/amps/powerlight/powerlight.htm),
that would put 4000W @ 4 ohms in each driver.

would that be ok? thanks m8s

You need to change your name to your real name or the thread will get locked and deleted.

4000 watts is 1.2dB over the rated program power.

Of course the real question on whether it would be fine depends on the program material-how hard you push the amp-how much compression/limiting and so forth is being used etc.

It may be more than twice as much power as you should be using, or maybe even a little low.

It depends on your circumstances/music.
