The obvious choice is the ef500p. I believe the advantages are; the filters(xovers) and amps match and it should just be a plug and play rig. And I believe the disadvantage is the 60 deg horn and I know the weight is a disadvantage. I think another advantage to this box is that it has a true 2" throat horn similar to the JBL 2245 which I'm pretty familiar with. This thing will cut for loud rock bands which is what I do.
The other contenders are;
the EV ZXA5 and I also believe the disadvantages to this box are #1, the price-about 50% more- and it has no clip indicator light. Also, it's a plastic box.
Advantage- the weight. It's Loud and it has a 90deg horn, but I'm not sure the horn is a true 2" throat.
the Yamaha DSR115. I've heard a lot of good about this box. I've heard it's Loud and can keep up with the Yorkville subs. It's got a 90 deg. horn but again, I can't tell if it has a true 2".
I've been scouring the web for info and I've come to the conclusion that a lot of the comments are from DJ's and they don't necessarily apply to live, loud rock bands. The gigs that I do, we play as loud as the bar will let us. With my old JBL system, I could feel it thumping from onstage and it just didn't sound right unless I could kind of feel surrounded while playing on stage.
Also, the reason I'm hung on a 90 deg horn, is I do not plan on ever adding another top to array them and I think a 90 deg horn is more versatile for the smaller speaker on a stick gigs that we occasionally do.
So those are the contenders, the Yorkville EF501p, the EVZXA5 and the Yamaha DSR115.
