I have used 5 months
Systm + full efficiency, compact, and robust Polyval .- box a bit heavy.
I have not tried other Systm because I immediately liked
Excellent price quality ratio I think the product is very well placed on the market and guarantees seem srieuses.
I pass the sub pro, pro 12 and pro 15 peavey home a little this system can not compare these two product ranges Different.
