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).

My Meadowlark Kestrels have the all time worst factory spikes, an obvious afterthought, especially in view of the otherwise wonderfully crafted cabinets. That said, I simply put 25 lb. bags of lead shot on top of each speaker and Newton's third law on a leash. Big improvement in image and bass clarity.

JD; you are correct. I just mentioned J. Dunlavys's comments because he is a well respected speaker manufacturer, and I found his position regarding spikes "interesting".

Until a few weeks ago, I didn't even know Dunlavys weren't spiked. I personally think that conditions would dictate whether or not the speakers (Dunlavys) sound better with spikes or not-- regardless of how they measure-- or who they are made by. BTW, which model Dunlavy's do you have? Cheers. Craig

I have the IVa. I started with the III and loved them, but always wanted the IV, it was an ego thing I think. The IVa has much better bass definition, the III's have a midrange to die for. I never tried spiking just because of the weight and not wanting to lose the perfect speaker location it took so long to find. I would love to here if anyone has tried spiking on there Dunlavy speakers. GREAT SPEAKERS CRAIG! J.D.

Ikarus, the sound being produced inward on a speaker is a concern that relates to interior dampening. If your speaker is physically moving in the opposite direction either it is too light or the volume is too loud. This movement problem is best solved by speaker weight which in term reduces cabinet vibration. If any one disagrees please respond. This is simply my common sense approach.

Marsh, be assured that my speakers do not move (except when I want them to :)). I'm expressing my surprise to the suggestion of Aurios and/or Roller Blocks under the speakers - which, in my opinion, will cause the speakers to move. I'll stay with spikes.
