the box PA 502

Simply amazing value passive PA speaker.

I'd even say amazing, period, regardless of price!

Works perfectly as FRFR speaker for an "amp-less" setups.

I use it as such for my bass, and it sounds significantly better than my dedicated and much more expensive SWR Triad bass cabinet.

Quite neutral representation of whatever signal you feed it with, really clear and well balanced reproduction, and with an outstanding, but tight and punchy, low end response, unheard of in PA speakers even many times this one's price.

Just astonishing sounding!

Only negative I can think of to say about this PA speaker is that it is quite heavy.

Well, and I guess the fact that it is the chasing is plastic, but to be fair most PA speakers are, even so called high end ones.
