Try without the Heil. I bet the overall bass improves because you’re doing your main amplifier a big favor by increasing the impedance it has to drive. Just try it.

The heils are a recent addition so I have listened extensively without them. I just run the Heils off the high / mid side of speaker binding posts with a 3.9 film cap in line.
