[QUOTE="Jim McKeveny, post: 132457, member: 2978"] Re: How will removing Ferrofluid from a Celestion CDX14-3050 affect it's response? I am ever the contrarian Art. "Easily" and "battery of frequency response, power handling and distortion tests" do not seem a complementary pair. When ferrofluids were introduced to loudspeakers they appeared a silver bullet: eliminate the air gap and enhance heat transfer away from coil. The "damping" was an assumed advantage, but likely a variable over a temperature range as fluid viscosity changed. That ferrofluid has not become routinely utilized in top products by most high end pro and consumer speaker/driver mfrs. makes me suspicious of real audible benefit. Or is it a power handling Hail Mary? Maybe someone here can offer a paper/publication otherwise. [/QUOTE]
