The above question was sparked off by reading this quote by Keith Horward (HFN):
"When I was a nipper reflex speakers were a good deal less common than they are today, with the closed box alternative a lot more prevalent. Why? Because closed box loading better controls cone excursion at very low frequencies, obviating the cone flap that occurs when replaying warped or rippled vinyl, particularly if the arm-cartridge combination has a poorly placed and damped fundamental resonance.
By using up available cone excursion, and perhaps even pushing it beyond the driver’s linear range, this infrasonic diaphragm dance squanders output capability and increases distortion. If you’re an LP user, this is something to bear in mind when considering any reflex loaded speaker."
Most of the speakers that I used when I owned a TT (70s / 80s) happened to be sealed, but I wasn't aware of this as a possible advantage.....any thoughts / experience on this from you knowledgeable folk on here........?
