Good evening lads,
After finding a suitable 15" driver available locally to replace the 3015CXs in two of six T48s, the SB Audience Rosso-15SW800

https://www.sbaudience.com/index.php/pr ... o-15sw800/

Which is has 11.28 Xmax with an 800w AES rating
l've now confused myself on Xmax/AES and vlimits
Using the plans guide for vlimit for a 15" with 11.28mm Xmax, we're at 60v, though the 15NL9300 is mentioned at 80v as it's 800w AES, but with 8mm Xmax.
And then l'm wondering if l fit the pair of 15SW800s, will they need more voltage to deliver their excursion than the 3015LF and LAB15s in the other 4 cabs..? Needing more amp channels & DSP
On one hand my thoughts are, l can fit the pair of 15SW800s and run 60v limit & not miss out on output from those two cabs. The other is replace all 6 drivers and move to 80v limits.
I understand these are maximum limiter settings, real world setup is more conservative.

Personally I wouldn't be mixing drivers, which can result in having to use different EQ and limiting, which can lead to driver killing mistakes. Pick one and stick with it.

Yes, l agree. If l were to change to all 15SW800s, would l set a 60v or 80v limit?

60v. It's set to the Pe or Xmax limit, whichever is lower.

Ok great, thank you Bill
