Hello,
I have a crown XTI 4000 powering two 36 inch wide T48's. I Also have a Driverack PA2 available. Are the onboard limiters in the XTI sufficient? Or, would the driverack be better suited?
Also, how to determine how much limiting?
Thanks in advance

If pack/transport space allows, you could build 4 36" t48's and swap all of your existing drivers over and wouldn't need to purchase any additional drivers, amps, or cabling. And... four 36" cabs is less pack space than eight 20" cabs as well as half the number of cabs to place and s...

And that's 1 driver in the 36 inch?

Are you saying 2-36 wide with 1 driver will outperform 4-20 inch wide with the same driver. We are talking single driver per cab, right? Yes, correct. But, it would be too close to hear the difference. If 20" is your limit, it is what it is. Still a bad ass cab. Based on that, I would get simi...

Thanks, makes sense. It's been a while since my last build. I just wanted to make sure I'm up to date.

Welcome back! Build these next four 36" wide if you can manage the size. If not, build as wide as you possible can. Two 36" cabs will outperform the four 20"ers you have now. 20 inches wide is due to packing restrictions. I wish I could go wider. Are you saying 2-36 wide with 1 drive...

20 inches wide is due to packing restrictions. I wish I could go wider.

Hello folks, First post in a while for me. I want to start if by saying how much I've enjoyed this forum. So much useful information from knowledgeable folks. So, to the question. I currently have 4-20 inch wide T48's loaded with 3015lf's. I'm now in the process of building 4 more. I'm wondering if ...
