Audiophile speakers that get loud

@bundy --

What high-pass filter(s) have you been using? I’m using the Xilica XP-3060 in my own setup, and find it to be virtually transparent with my (passively filtered) mains high-passed.

So, maybe the Xilica could be the solution high-passing your C1’s between 80-100Hz (the XP-2040 would do and retails for ~$1,000), and while we’re at it add another JL Audio sub. 

A better more massive rack for your turntable.

Stuff the ports. :)

The excursion happens because below the port, the woofers have no resistance at all.

Stuff them. This will raise the natural -3dB point up a few Hz, but greatly increase the dynamic range they can play out before they hit max.

Compensate with new sub settings.

Loud and small don't go together, Sir.
