snom PA1 and Valcom V-1080

[sunstate]

I need to put up a single PA speaker in a small warehouse. I think the snom PA1 looks like the great little box, especially for the cost. 888VoipStore recommends the Valcom V-1080 with it, but it's $65. What is special about this horn? Anything? Just trying to figure out if I need to spend the extra money on it or if any off the shelf $20 PA horn will work fine.

Thanks,

I'm assuming that the 4w output of the PA1 isn't enough for a cheap, un-amplified horn?
