It's very hard to list a top ten speaker of all time. Too many price points, sizes, personal tastes and etc...
But from a dollar to dollar perspective my pick is clearly the Dunlavy SC-IV signature series. Nothing I mean nothing can touch these speakers "overall performance for the money". I have owned speakers in the price range from $2000 - $90,000 retail and the Dunlavy SC-IV signature series speakers impress me the most.
Only drawback is they are big and not th easiest to setup. But once you give these classic speakers the right amount of space and excellent electronics & cables they deserve to have. Wow ! You will hear what I mean.
Another drawback is you can only find the Dunlavy SC-IV signature series speakers preowned since they are no longer in business. The only reason why Dunlavy is no longer in business is because Mr. John Dunlavy became very ill and retired there after.
I am a critic of Stereophile at most times. But back in 1994-1995 calling the Dunlavy SC-IV's product of the year was rightly so accurate. The signature series are even better sounding than the orignals. And forget the Dunlavy SC-IVa speakers. Dunlavy became ill and rushed for an upgrade in actuality cheapened a few things which took away the magic from the Dunlavy SC-IV signature series.
There are a number of worthwhile additional speakers to mention on there greatness but the Dunlavy's stand out in my mind.
