Speaker plinth material bottom ported Zu Omen Defs

Currently my Zu Omen Defs sit on hardwood floor ( bamboo) in my basement finished listening room. Even though we are very good at keeping sewer cleared, video checks every year, I’m always paranoid about water overflow. Our basement is bone dry. I would like to raise the zus off the floor about an inch or two with a plinth. IMO, mapleshade’s at $600 + each is pricey. I can make my own. My question is wood vs granite on bottom slot ported speakers like Zu. One would think that granite may be too reflective for bass vs wood. Just curious if anyone has any thoughts. For the trolls: yes we have flood insurance, sump pumps, etc. I’m not moving the gear back upstairs. Just asking about best material. 

Thanks

Btw, I’ll be keeping the speaker feet intact so GAP between speaker would be the same as current gap

Thanks for reminding me about ZU's great customer service. I wish I thought of that earlier and called last week. I will call or write ZU after New year. I was fine with the bass response upstairs for the last 5 years (oak wood floors). An actually fine with the bass response now (Bamboo hardwood flooring). So I would probably be fine with a plinth of either wood. Just curious if their is an optimal wood or material for such a use (with bottom slotted ports on speaker). I use to correspond with Sean Casey quite a bit a few years ago. I'll dig out his email address.

Thanks for info. I think you are right, I’m paranoid from a flood many years ago. So the plinth does not take place of the floor since it’s solid?

Basically I’m adding a block of wood or something on the floor. Taking the speaker as is and lifting on top of the wood or whatever. I’m maintaining the same gap ( using the floor spikes) that I am currently.

Why isn’t there moisture now? There’s a vapor barrier between concrete and wood floor? So if speaker is on spikes on top of the plinth, I don’t see the difference. I guess I could put small feet on the plinth

I wrote Sean at Zu. I'm looking forward to hearing his thoughts.
