Cones vs. factory spikes?


Has anyone done any A-B testing for various speaker cones? Currently, my KEF REF 4s (120 lbs each, ported base) have the factory spikes. Before spending big bucks on Orchard Bay cones (used on Talon Khorus and recommended by my dealer) or Black Diamond Racing (why is their web site is abysmal?), I would like to know what others have used on the bottom of their speakers and if they make an "audible" differnce. Rest of system (for 2 channel) is: Aranov tubemonos, firstline pre, Sony SCD-1 (on order).

There was a thread from 2-6-01 entitled, "Talon Khorus owners, please read" that you might find interesting. The poster said the Sistrum SP-1 platforms were even better than the Orchard Bay cones with his Talon Khorus'. I've not used them, but their website is www.audiopoints.com. Good luck.
Try the BDR or Polycrystal speaker cones, thread them almost, but not completely, against the speaker bottom face. These two work the best for me on carpeting. If you're lucky enough to have hardwood floors, or VERY low pile carpet, try the Audios MIBs under the speakers. Wow. Like you, I despise the simple spikes even the most expensive speakers seem to provide as factory equipment. Awful sounding, and don't inspire structural confidence, at least to me. I always fear the damn things will shear right off with heavy speakers, you know?
Most factory spikes are just threaded rod ground to a point on one end with locking nut, almost an afterthought. I use "collossial" Polycrystal cones which are 2" tall brass coated with polycrystal material. Does clearly provide better sound all around over factory spikes and cost $160 for a set of eight threaded cones. I was told by dealer to tighten cones against speaker bottom to completely couple for best sound. You can loosen one cone as needed to level.

Also as Evans said don't be afraid to experiment with other speaker mounting methods such as Aurios MIB, RollerBlocks, Vibrapods etc. All produce different sound. Sistrum, mentioned by Macm, and others make speaker platforms with spikes built in, can get expensive though (as can Aurios MIB for speakers)
I think you guys are CRAZY! "Cones or spikes....hmmm what sounds better?" Nothing wrong with being nuts, eh?
