Hi
I've got some Monitor 10's but have heard and read some things about the 12's...it seems there are two kinds of 12's. The RTA and the Monitor series 2 12's. What is up ?
Is the RTA the real time array ?
Is the RTA the ones with left and right speakers ?
And how would I ID RTA12 early/late ?
Would I be able to ID the Monitor 12's easily ?
