JBL EON 618 S

I recently purchased two active RCF Art15A speakers.
Having no active sub, I started the search, and I found these amazing JBLs.

It has just enough SPL, with 18", only 1000w peak (so it uses a normal power cord), goes really low (31Hz!), and a crossover.

When it arrived, I found that in the manual, there was no information on how to switch the frequency of the crossover, so I emailed JBL to get some info on that (about a week ago - unfortunately no answer yet), so that's a minus.
A good thing about it, though, is that it's bypassed, so, even if the sub is off, still passes the signal.

But besides that, it sounds just amazing, and if set right (with proper volume & eq) it just gives the lower frequencies a nice boost without getting in the way of the mids.
But you can also get a good sound, pretty much, straight forward.

The sound quality is just amazing.
And considering everything it probably is the best sub you can get fit the price.

I'm really satisfied.
