Has Anyone Here Tried The SVS Soundpath Feet On A Rel Sub?

You are right @ millercarbon. My mistake. It couples it to the floor which is what Rel wants to happen. I knew Rel’s had a different approach. I just didn’t know how big the difference is. This may be the reason for poor reviews by some. I suspect that posting this tidbit will only give cannon fodder to the Rel haters.

From the article

The cost of the Blu-Tack solution is extremely affordable and it works better than any other material. We do not recommend the use of spikes or platforms as they do not work well on RELs or any high-quality sub. Remember, the goal is to couple the subwoofer to the floor and transfer the energy into the room.

The more efficient the subwoofer’s mechanical pathway is, as is true with REL subwoofers, the bigger the jackhammer.

Platforms change the height off the ground (as do spikes) which will have a negative effect on the performance of your REL. The higher off the ground, the less bass will transfer into your room. You may well be surprised at how much better the sound is once this has been completed and for almost zero cost. Enjoy.

Thanks guys. FWIW, my system sounds fabulous. But I've learned that through the tweaks I have made that it can sound even more fabulous. Thus my question? That said, ....
@b_limo & @ dadork    Thanks for the recommendation. Though it does seem to go against the REL design, I will check it out.

@rdk777    After reading and listening to the REL rep in the link I provided, I understand why you had the results you did.
@oldhvymec I understand your concerns. Honestly, I had the same thought AFTER I listened to the video which I posted. It's also the reason I said "isolation" in my OP because my mind would not accept the idea of coupling the sub.

That said, I've owned REL subs for 15-18 yrs. They have always been known as being excellent for music. Quite honestly, they sound great when properly set up. But early on users most always recommended turning the crossover as low as possible which sounded right and the volume no higher than necessary. the sub should disappear just like the speakers should do.

Most Most people who know me knows of my love of good bass. This is probably due to my playing drums for 50 yrs and the importance of hearing the bass. That said, I disagree with many who prefer the "fast & tight" bass of SS. I was never fully please with the SS amps because my experience tells me that bass is NOT tight.  It was only after trying a tube amp that I got "proper" sounding bass.

 I would recommend everyone to watch the Rel video. they talk about their filters being very important. I have no real electronics knowledge. But I know sound which is why I choose the Rel. But I will be re-thinking and trying to make sense of it all.
