I’d ask HD about the 520c I think he has one I’ve not herd good things about it in reviews . Now jbl’s compression driver technology is the best so this might work for you . They need a solid 3 way for this lineup in my opinion. I’d look at the HDI center it’s built right and is definitely more dollars.\n\nI have one but not using it with the rest of the studio 5 series at the moment, replaced it with a 3-way Infinity RC263 I got on sale for $150, moved the 520C into a mish mash system in a spare bedroom (where it works just fine). I may swap them back to see what stands out as a difference, but just thought at higher volumes the RC263 was a bit better\/cleaner. I'd still rather have something from JBL that matched the 590s better, tho....too bad they never made one (but will look at the HDI center now that you mention it).
