2. Boomy but not muddy. While you want your floor tom to be resonant, you don't want it to be muddy or indistinct. There should be a clear distinction between the pitch of the drum and the overtones.
3. Sustained sustain. Floor toms have a relatively long sustain time, so it's important that the sound of the drum continues to ring out and not die off prematurely.
4. Clear articulation. You should be able to hear each individual drumbeat clearly, even when the tom is being played quickly. There shouldn't be any overtones that interfere with the clarity of the drumbeat.
5. A pleasing tone. While it's ultimately up to the drummer to decide what the "best" sound for a floor tom is, most people appreciate a floor tom that has a deep, warm, and pleasing tone.
