just have to comment on the above " Although I’m not a huge country music fan, I find the Brooks and Dunn track "My Maria" to be a great track to audition speakers to, because it has really well recorded drums, that challenge the mid-bass reproduction abilities of most speakers." (i suspect that corresponds to your port on your Focal)
Wow that is a joke ! that wouldn’t challenge a pair of BBC ls5a
Try Al DI MEOLA Flesh on Flesh SACD -most ported speakers fart out that much bass not funny it is incredibly revealing of bass quality quantity and rhythm and timing -many tracks on this are just incredible
Also for strictly drums get the Sheffield drum and track test cd - turn that up -very well recorded drum solo not overdone rap bass tracks
