Subwoofer Isolation, what do you think...

I just got this big honking subwoofer, a DD-18 Velodyne. I've a ceramic tile over concrete floor. I also have a nice turntable in close proximity to the only WAF approved site for the big honker. Anyone have any feeling for if the adjustable feet that came with the DD-18 are enough or should I replace them with cones or something else? I always use the sub even with the vinyl as it adds so much depth to everything. I can't say my turntable's stand is very good, it isn't but I'm working on finding something good (and affordable!). I am concerned though with this big thing so close... maybe within four feet.
Thanks People!

Oh Yeah get a 25lb bag of #6 (I bought #7.5 instead because that is what the gun shop had in stock and it works also)lead shot and throw the bag on your sub with whatever isolation you choise it will tighen up the bass more by adding mass to the top of the sub cabinet. Especially with an 18" subwoofer cabinet!

I had the same problems with my Velodyne FSR1800X Subwoofer next to my Projector stand shaking the pj. I tried Aurio 1.2's first and then went to Aurio Pro's to Decouple my Subwoofer from my tile floor. I also went through that same process to float my 17lb projector to take it to the next level. I am going to do a shootout with my Sistrum SP-4 stand under the subwoofer again which tightened up my sub considerably in the next month once I stabilize the changes in my system. I use 2 sistrum full racks for my video and audio system.

I understand a 25lb of shot on top of a gloss black sub is not WAF compatible but it can put placed on the sub when listening only. I thought my 105lb velodyne was well built enought but the top is still less than 1" thick and not brased enough. Bob at www.audionut.com suggested this, but he dresses up the bag with a dress black sock slipped over it (make sure not to use a goldtoe sock)
