Should I build plinths or screw spikes into cabinet?

I've got a great old pair of B&W DM640 floor standers, but I don't have the plinth and spike kit that were sold as an option back in the '90s.  Since I have been unable to track down a kit online or directly through B&W I am planning on building my own.

The speakers themselves were built without any isolation system on the base of the cabinet, and were set on top of adjustable "lugs" which were incorporated into the top of the optional wooden plinths.  Each plinth had four basic spikes mounted at the corners.  This sounds easy enough to replicate.

Does it make more sense to simply drill into the base of the cabinet and mount the spikes directly?  The tweeters are nearly at ear level, so I don't need to lift them much.  I am a little hesitant to make any permanent alteration to the speakers, however.  Any opinions or alternatives are welcomed!

guitared, You should go under your house, find the area to support with bottle jacks and 4x4's. (or equivalent), After this, (if needed),you may look at look at other options above.

(All of this will keep you under your $100.00 target... I'll make a bet that it will be the ticket...just requires some effort.)

The main reason I like (spikes), it allows me to fine tune speaker placement which I find to be critical. If you don't feel a need to drain vibrations away, the Vibrapods may be one solution. Some may have monitors that allow this adjustment to be made between the speaker and the stand.

I've found that with suspended wooden floors, there will be (out of level) floor issues that require a more thoughtful approach that may include having several methods of adjustability.

My post was out of what I feel to be the need to address the main issue first: your suspended wooden floors. (I have a similar issue) This should be done first and addressing this basic issue will be beneficial for every aspect of your listening pleasure and system upgrades from now on.
Good luck!
