Thanks. I'm just worried about the 1602 he is selling. He said that he used it for some events when he does DJing. He also used it home. But he also said it was not frequent. He also mentioned that I can come and listen for it. Of course, most sellers will say that it was infrequently used. Problem is, I don't know what to look for when it's in front of me.
He said that the bottom price he can give to me is $320. I'm trying to haggle it for $250.
So what should I do then? I was actually planning to buy 2 more Fi18" drivers but not this year. Looks like 1602 won't be able to handle 4 drivers but EP2500 can. The reason I was leaning towards QSC is because I can get it locally although used. And also from my research, I've found that QSC is more reliable. Another good news I found last night was that my friend knows someone at Guitar Center. He can get me 10% off plus another $100 rebate that QSC is offering.
Can you guys help me with this since the model RMX1450 will be fit my budget perfectly. Currently, I have 2 Fi18"s. Will it be able to handle 4 drivers though?
