Having done this dance with my 125 lb Tekton’s ( please don’t flame me 😆 ) I’m a firm believer in decoupling. I use Townshend Isolation platforms. At the size of your speakers Townshend’s would be HUGE and expensive. You can search my history from last summer and read the thread regarding suggestions. I’d look at Gais’s , Auva, and Herbies from expensive to less expensive. FWIT Townshend also offers bars Vs platforms when you look at their stuff. Also when I did my search , I was contacted ( PM ) by the Townshend rep during my thread. I made my purchase through the AGON site and used the make offer option and this was significantly less expensive than list price. Also in making my decision all of the sellers were very responsive to my inquiries. If I may suggest, be sure to consider height adjustment since your speaker has a large footprint and you have hardwood floors. Happy Hunting, Mike B.
