Driver question for titan 39. We are going with a pair of 12 inch drivers for 2 separate cabinets. These are going in a small church 40 x 60 or about 2,400 sq feet permanently fixed mounted.
My question is on what drivers to order. Choices are: Delta 12lfa, Kappalite 3012 lf, lab 12 and s2012. Also, there are some Eminence Impero 12a Pro at a discount.
please advise. Also, please comment if you think 2 cabinets are too much. These will be running with a pair of SLA pro with 4 drivers.

2 cabs with 3012LF.

Before you permanently mount them - be sure to learn about proper sub placement.....it truly makes a difference.

6 - T39 3012LF
4 - OT12 2512
1 - T24
1 - SLA Pro
2 - XF210

+1

Sub placement in a room can make or break an otherwise well thought out system.

Please feel free to ask placement questions if you have them. What you think it "should look like" is, in many many MANY cases, the worst place to put them.

Yep. Subs are like real estate. What matters most is location, location and location.
