Is active pa the right choice

Recommended Posts

Looking to upgrade pa again. Im currently using jbl mrx 515 over srx718, feeding each cabinet 800 watts. Looking to switch to 812sp over 818sp. This is for live rock band. Question is howmuch improvement could i expect? Hoping for better intelligibility of vocals along with overall cleaner sound and of course i want more kick on bottom.

You will gain some clarity in the tops and probably a little more transient range, as a result of the processing/biamping.

 

I really don't expect you will gain any bottom over the 718s at 800w on the low end. Those are nice boxes powered well. But the convenience factor alone may be worth it

Do you think id be better served by just finding some 712 tops? Also does anyone know if the 828sp can be stood on end?

So ive purchased 812 over 818 Trying to make some power/signal siamese cables. Does anyone know if the 812 has to be wired from 818 or can i put a “y” in signal cable

By the way The srx812 blow away the mrx 515. Not even close. The 818 arent much of an improvement over srx718passive

You input into either the tops or the sub. I think you input into the sub and set the output at an xover point to the tops. I have not read the directions so do not make a y cable. Read the manuals on your tops and subs. You can get manuals here.
