Have you tried adjusting or removing the suspension mounts? If the bands aren't perfectly formed, they might have squeezed them onto the lugs, which could in turn be choking the shell.
What are these drums made of?
Just a suggestion.. At least before you sell it.. MOVE it to some other rooms if you have the availability.. and try it out. Different thickness shells will sound different depending on the room and construction. This happened to me MANY times and I thought I got dud kits or something. My cement floored , wide open garage was WONDERFUL for thicker shells. HORRIBLE for my thinner kits. Once I moved my thinner shelled kits into smaller rooms in the house with carpeted floors.. it was all 110% there and then some.Dang!!!
I took delivery on a custom build Noble & Cooley Horizon kit about six months ago.
Stunning build quality and attention to detail. Absolutely zero issues with the fit and finish.
I’ve spent six months attempting to find the heads and tuning range for these drums. I can’t freekin hit it. I’ve gone through head choice after head choice after head choice - nojoy.
It just doesn’t have “that” sound and feel. It sounds like other Horizon kits … it just doesn’t inspire me. I’m not connected to it
From your first post:They aren’t thick shells by any means. They are also not super thin. Just an average ply shell these days. The Drum Room is a new build and has new carpet. You might be on to something there. I did a full buildout when I ordered the kit. Prior to it was a wood floor. I never considered the floor as I’ve played tons of kits in that room ... PRIOR to installing carpet and doing the buildout. It just never occurred to me in this process that the floor dampening would kill a kit to this level. I’ve played plenty of sessions in carpeted rooms ... and wood etc. I’ve never had it impact this extreme.
But I’m going to move the kit into another room with a wood floor to check. I’m leaving no stone unturned.
Man, I sincerely appreciate all the help.
