Problem was that I didn't realize those JBLs were actually bass drivers and not sub drivers.
DSP is a Xilica XP 4080.Ī few years ago I did a DIY project with a pair of 18 " JBL 2242 drivers, which didn't work out that well. I have some knowledge on how to use REW, so I was able to have all speakers time aligned and EQ'd flat. Currently I'm running a pair of Klipsch La Scala IIs, and a pair of Tuba HTLP's (=horn loaded subs).
