All the while you're thinking how "safe" your drivers are in their new sealed box home.
Add to this the loss of LF output of an A-S system compared to a ported driver system, and you'll be wanting to put more power to them automatically. We all know JBL coils can handle power... pretty soon you could be asking yourself "what happened to the lows and mids?":dont-know .
