Improving sub quality

I am close to pulling the trigger on a REL B3 sub, and wanted to know if anyone has noticied an improvement with replacing the stock footers (plastic) with a high grade cone/spike? I did hear a difference with switching out the stock PC, so maybe cones/spikes will make a difference too? Sub is on low-medium depth carpet.
Thanks,
Mark

I have a REL on carpet on a suspended wooden floor and it sounded worse on spikes. It surprised me, but REL generally recommend against spikes, so perhaps they know better.

I have found the best room loading to be out towards the middle of the room (just in front of one of the main speakers, following a Cardas placement method). REL's corner placement always sounded boomy to me.

KGveteran, I'm glad it worked out for you. If aesthetics permits you might want to try placing the sub non-centered, following the Cardas placement rules at

This placement was designed to minimize standing waves, and I figured if it works for the main speakers it ought to work for a single sub .... and I've found it does work, very well.

Semi's point is a very good one. It would make sense to me that a front firing sub would behave very differently to a down-firing sub.

I find it interesting that the B-series are advertised on Sumiko's site, but there's no mention of them on REL's home page. Are they designed only for the US market ?
UK and US requirements are a bit different, due to the larger rooms in the US.
