Because if you use 1000watts, then a little bit of clipping might be acceptable-which in most cases can happen easily on peaks, but if runnng 1600 watts and you clip, the extra excursion can be damaging.


If the growler clips a little bit at 1000 watts during peaks, then at 1600 watts it would clip even less due to the headroom....right? Not trying to argue, just trying understand.

Not the loudspeaker that clips but the amplifier that is driving it that we are talking about.

Yes using a amp rated for 1600 watts non clipped would be better than running a 1000Watt amp clipping a little.

But most people runt things right up to and past the limit, that is why Jeff said what he did-I assume.

1600 watts is only a hair bit more than 1000watts-a small hair.

I understand that. I should have worded that a bit better.

That, and maybe for marketing purposes. Rating it at 1000 watts makes it appear more efficient and thus a smaller amp can be used to run the growler.

We actually had a well known consultant (in some circles)complain about the rating of the TH115, 1000watt @ 8 ohms.  He was saying that it would be a problem getting an amp that had enough headroom.  He wished it was rated lower so he could use a smaller amp Shocked

Just because it can take a particular amount of power does not mean you have to use that large of an amp.  You can always underpower a loudspeaker, you just won't get the maximum performance out of it.

I don't follow what you are saying 100%.

If clipping will push the driver farther than 1600 watts will, why is 1000 watts recommended? Are you saying that 1000 watts is less likely to clip than 1600 watts? It seems to me that the bigger amp with more hearoom will be less likely to clip than the smaller amp.



I'm not sure if this is the missing piece of information but an amplifier clipped to a square wave will put out 2x power. So a 1000W amp is capable of more than 1600W when square waved....  

Now I'm sure nobody ever does that to subs...   Laughing

You are correct sir,

A 1000watt amplifier producing a square wave doubles the RMS power to the growlers rated thermal capacity of 2000 watts however still within the 32mm each way mechanical limits.

Nope. No one. We used DJ's to beta test these. LOL

I have two configs over here in Boise. (1)A block of 6 Growlers run with 6 ea crown macro-tech 2402's bridged. Amps just idling along. Lots of spl. Config 2: A block of six growlers, Two growlers paralleled to one side of a Crown 2402. (using 1 1/2 Crowns). Crowns are working pretty hard. The amps are not very happy at the 4 ohm bridged mono with these growlers. They told me so.....

How well would a bridged Crown XTI 1000 per cabinet work on these?

Honestly,

 I wouldnt do it! Save some money and get an amp you can run the same power in stereo. I had the xti-4000 and now have the QSC PL6.0II....couldn't be happier. the xti-4000 just wasnt doing it for me bridged. the amp would clip prematurely and get maxed out easily. no headroom! just my $.02
