I too have the K8.2 stereo pair. I did add the QSC KS112 powered sub because I was missing the punch or bottom.

Now, right before Christmas, I just came across a great deal.
On the same day, I got an offer on my RCF ART 312a mkII speakers... the guy paid cash. Three hours later, I sold my pair of RCF ART 310a mkII speakers. I wanted to upgrade my 12” speakers and I found a deal on Facebook Marketplace for an open box RCF ART 732a mk4 with cases for only $680 a box. I sold 4 speakers from 2010 to buy 2 new 12” speakers.

I had 2 gigs with them and the sound great... much better with my Genos compared to the QSC K12.2.

Only 40 lbs... “1400w”... the cases can stay on the speaker and you can still but them on the pole... lower crossover point for better bass and clean highs. Great sounding box! $600 per speaker and $80 per case. The RCF ART 732a are normally $899 per speaker. Also check out the RCF HD12A compared to the QSC K12.2.

Have fun!!
