I use these speakers in mobile disco for 3 years.
They are fed with the CX 1200, the same brand of amp.
Before that I need a pair of double 38 first prize (XXL brand, type of home AudioPhony fiesta) ... It has nothing to do!
Very happy with this purchase, it's really big sound real cheap ...
I confirm that the sound is really good even with minimal treatment (3 bands on my mixer !!!).
It is true that their weight and the coating are that they must be handled with care to stay in good condition (especially for mobile installation).
The value is excellent.
I hesitate between buying another pair of A30 or subwoofer (I like the sound quite heavy).
No regrets for this purchase, I would definitely do it again!
