Any way at all to downplay the bass for my pair of Phantom Golds?

[ogs]

I was just demoing the KEF reference 5 and B&W 803D3 and I really liked the KEF. One major difference with softer music is the bass from Phantoms are too heavy. Not that I'm trying to match them but I wonder if there's a way to do it as titled as it would fit my taste better.

One method: digital room correction. Phantoms respond very well to DRC. If Roon is the player, this is quite easy. REW should be able to create a suitable amplitude correction filter that can run in Roon's convolution engine.
